Overall remediation

As at the end of December 2024, there are 5,011 residential buildings 11 metres and over in height identified with unsafe cladding whose remediation progression is being reported on in this release, an increase of 13 since the end of November 2024.

Since the department first began reporting on all five remediation programmes in October 2023, 1,214 more buildings with unsafe cladding are being reported on in this release.

Overall, 2,403 buildings (48%) have either started or completed remediation works. Of these, 1,472 buildings (29%) have completed remediation works.

Figure 1: Of the 5,011 buildings identified with unsafe cladding, 2,403 (48%) have started or completed remediation works, of which 1,472 (29%) have completed remediation works. This includes remediation progress on high rise (18m+) and mid-rise (11-18m) buildings in height.

Note: From October 2023 onwards combined remediation progress is shown across the BSF, ACM programme, Cladding Safety Scheme, developer remediation contract and as reported by registered providers of social housing. The total number of buildings identified with unsafe cladding, reported in the overall remediation section of the data release, does not sum to the total number of buildings in each remediation programme, reported in each respective section of the data release. This is due to some buildings appearing in more than one remediation programme.

The increase in the number of reported completions between May and June 2024 is largely due to a change in methodology in reporting social housing sector remediation, which from June 2024 includes social housing buildings that had completed remediation independently of government funding and monitoring schemes before March 2024.

ACM remediation – monthly update (as at end December 2024) since previous publication

As at 31 December 2024 of the 514 high-rise (18 metres and over in height) residential and publicly owned buildings with ACM cladding systems, unlikely to meet Building Regulations, 492 (96%) have either started or completed remediation works, no change since the end of November.

Of these, 446 buildings (87%) have completed ACM remediation, including those awaiting building control sign-off, an increase of two since the end of November.

There are 22 buildings yet to start ACM remediation (4% of all buildings), no change since the end of November. One building is vacant so does not pose a risk to resident safety, 18 occupied buildings have forecast start dates, two further buildings have had local authority enforcement action taken against them, and the remaining building came into scope in 2024.

Building Safety Fund (BSF) – monthly update (as at end December 2024) since previous publication

As at 31 December 2024, of the 809 high-rise (18 metres and over in height) residential buildings proceeding with an application for funding through the Building Safety Fund, 157 buildings (19%) have started remediation works and 364 buildings (45%) have completed remediation on unsafe non-ACM cladding, including those awaiting building control sign-off.

Overall, 521 high-rise buildings (64%) in the BSF have either started or completed remediation works on non-ACM cladding, no change since the end of November. Of these, 364 buildings (45% of buildings) have completed remediation works, an increase of seven since the end of November.

Cladding Safety Scheme (CSS) – monthly update (as at end December 2024) since previous publication

As at 31 December 2024, 525 buildings 11 metres and over in height have been assessed as eligible for the Cladding Safety Scheme (including 109 buildings that have transferred from the BSF), an increase of 33 since the end of November. Of these, 53 buildings (10%) have either started or completed remediation works, an increase of seven since the end of November. Of these, 17 buildings (3%) have completed remediation works, including those awaiting building control sign-off, an increase of one since the end of November.

The CSS continues to investigate and pull in potentially eligible buildings. There are a further 2,415 buildings 11 metres and over in height in the pre-eligible stages of the Cladding Safety Scheme, which launched fully in July 2023. Of these, 314 buildings are progressing through eligibility checks, and 2,101 buildings are in the pre-application stage.

Developer remediation – data received from developers as at 31 October 2024. Data received from other programmes relating to developer-led remediation is as at 31 December 2024

Data received from developers is accurate as at 31 October 2024, except for one developer (Frasers Property) who did not submit data within the deadline. For this developer, the data release uses the data they submitted as at 31 July 2024.

As at 31 December 2024, 1,745 buildings 11 metres and over in height have been identified as having life-critical fire safety defects (including cladding and non-cladding defects) which developers have committed to remediate or pay to remediate (where the cladding remediation works are being carried out in a government funded remediation programme), a decrease of one since reported in the November data release.  

Of these, developers reported that 850 (49%) have either started or completed remediation works, no change since reported in the November data release. Of these, 439 (25% of buildings) are reported to have completed remediation works, no change since reported in the November data release.

When excluding buildings reported with only non-cladding defects, there are 1,535 buildings which developers have reported as having unsafe cladding, of which 790 (51%) are reported to have started or completed remediation, including 397 (26% of buildings) which are reported to have completed remediation.

Social housing sector – data received from Registered Providers of social housing as at 30 September 2024, data received from other programmes relating to social housing sector remediation is as at 31 December 2024

As at 31 December 2024, 2,606 social buildings 11 metres and over in height have been identified as having life-critical fire-safety cladding defects. This is no change since reported in the November data release. These have been identified using survey data submitted by Registered Providers of social housing and data on buildings the department is monitoring under other government programmes (ACM programme, BSF, CSS and Developer Remediation contract).

Of these, 1,176 (45%) are reported to have started or completed remediation works - no change since reported in the November data release. Of these, 728 (28% of buildings) have completed remediation - no change since reported in the November data release.

Enforcement – monthly update (as at 12 December 2024) since previous publication

As at 12 December 2024, local authority enforcement action has been, or is being, taken under the Housing Act 2004 against 506 buildings over 11m with unsafe cladding, an increase of seven since the end of November.

Building safety overview

This data release publishes data across all government remediation activities to give an overview of the status of progress to remediate unsafe cladding on residential buildings over 11m in England. This includes:

• Data relating to the Aluminium Composite Material (ACM) cladding programme – those highest risk buildings that are high-rise buildings with unsafe, ‘Grenfell-style’ ACM cladding
• Data relating to the Building Safety Fund, which funds the remediation of eligible high-rise residential buildings with other forms of unsafe cladding
• Data relating to the Cladding Safety Scheme, which funds the remediation of residential buildings over 11m in height with unsafe cladding
• Data relating to developer-led remediation, which reports on those buildings that developers have agreed to remediate
• Data on residential buildings over 11m in height that are the responsibility of registered social housing providers.

Overall remediation progress

Figure 2: 2,403 residential buildings (48% of identified buildings) have started or completed remediation on unsafe cladding, of which 1,472 (29% of identified buildings) have completed remediation works.

Overall remediation: key statistics

Of the 5,011 residential buildings 11 metres and over in height with unsafe cladding the department is monitoring, as at 31 December 2024:

• 1,472 buildings (29%) have completed remediation, including those awaiting building control sign off
• 931 buildings (19%) have started remediation
• 2,608 buildings (52%) have not started remediation

Since the end of November 2024:

• The department is monitoring the remediation progress of 13 more buildings.
• 6 more buildings are known to have started or completed remediation, and 9 more buildings are known to have completed remediation.

Since the end of December 2023:

• The department is monitoring the remediation progress of 1,172 more buildings, largely due to more buildings being identified with unsafe cladding in the CSS, and reported by developers and social housing registered providers.
• 795 more buildings are known to have started or completed remediation, of which 675 more buildings are known to have completed remediation.

There are an estimated 272,000 dwellings in the occupied private and social sector 11m+ residential buildings with unsafe cladding that the department are monitoring. Of these an estimated 92,000 dwellings are in buildings that have completed remediation, and an estimated 57,000 additional dwellings are in buildings that have started remediation. An estimated 124,000 dwellings are in buildings that have not started remediation.

Figure 3: Progress of remediating unsafe cladding differs across the programmes due to the differing maturity of the schemes.

England, 31 December 2024

Local authorities with 10 or fewer 11m+ buildings monitored with unsafe cladding are excluded from this map as their inclusion could lead to the identification of buildings with unsafe cladding.

ACM remediation

Information in this section is correct as at 31 December 2024 and shows a monthly update from the previous publication.

Figure 7: 96% of the 514 identified ACM clad high-rise buildings have started or completed remediation, with 92% having had their ACM cladding removed and 87% having completed remediation.

ACM remediation: key statistics

As of 31 December 2024, the department has identified 514 high-rise residential and publicly owned buildings identified with ACM cladding systems unlikely to meet Building Regulations, no change since the end of November.

• 446 buildings (87% of all buildings) have completed ACM remediation – an increase of two since the end of November. Of these, 420 buildings (82% of all buildings) have received building control sign off – an increase of four since the end of November.
• 492 buildings (96% of all buildings) have started or completed ACM remediation – no change since the end of November. Of these, 475 buildings (92% of all buildings) have removed ACM cladding – no change since the end of November.

There are an estimated 26,700-30,000 dwellings in private and social sector buildings that have completed remediation, and a further 5,300-5,400 dwellings in occupied private and social sector buildings that have yet to be remediated.

Driving ACM remediation forward

There are 22 buildings yet to start ACM remediation (4% of all buildings) - no change since the end of November. One building is vacant so does not pose a risk to resident safety.

Remediation Stage	All occupied buildings yet to start remediation	Of which:
		Enforcement action	Enforcement action supported by Joint Inspection Team	Forecast start available	Forecast to start by the end of March 2025
Total	21	9	4	18	4

Table 3: Enforcement action and forecast start dates for occupied high-rise buildings yet to start ACM remediation, 31 December 2024

Of the 21 high-rise occupied buildings yet to start ACM remediation:

• 18 buildings are forecast to start works in 2025, and seven of these have had local authority enforcement action taken against them.
• Two buildings without a forecast start date have had local authority enforcement action taken against them.
• The remaining building has been determined as in scope of the ACM monitoring programme in 2024, and the department continues to engage with building owners to ensure their remediation is progressed.

These forecast estimates are based on information provided by building owners and agents and may change as further information is received. These estimates can also change because of buildings being newly identified. The department continues to engage with building owners to start remediation works on site as soon as possible and will continue to support local authorities and fire and rescue services in the use of their enforcement powers.

Figure 8: 96% of buildings are forecast to have started or completed ACM remediation works by the end of March 2025.

ACM remediation progress by year of identification

Figure 9: 99% of buildings identified at 31 December 2022 have started or completed remediation compared to 96% of all buildings in the programme.

Since 31 December 2021, 33 further high-rise residential buildings have been identified with ACM cladding systems unlikely to meet Building Regulations and have moved into scope of the Building Safety Programme. Of these, six buildings were identified in 2022, eight buildings were identified in 2023, and 19 buildings were identified in 2024.

Building Safety Fund

Information in this section is correct as at 31 December 2024 and shows a monthly update from the previous publication.

Figure 11: 64% of buildings proceeding with an application for funding in the BSF have started or completed remediation, with 45% having completed remediation.

Table 5: Remediation status of buildings within the Building Safety Fund, 31 December 2024

BSF remediation: key statistics

As of 31 December 2024, 809 buildings were assessed as eligible and are proceeding with an application for funding from the Building Safety Fund. The remaining 2,857 buildings registered with the fund are either ineligible (1,112), withdrawn (1,601), in review or have given insufficient evidence (19), or have transferred to the Cladding Safety Scheme (125).

Of the 2,857 buildings that registered with the Building Safety Fund and are not currently proceeding with an application for funding, 455 buildings which were assessed as eligible have been transferred to developers

As of 31 December 2024, 125 buildings have transferred to the Cladding Safety Scheme for their remediation (where works have not yet started on site) and are progressing through the CSS process. The number of buildings reported as transferred from the BSF to the CSS in this section of the data release may not be the same as the number of eligible CSS buildings that have transferred from the BSF in the CSS section of the data release. This is because transferred buildings will go through CSS eligibility checks before buildings are included in the eligible CSS figures.

Of the 809 buildings proceeding with an application for funding in the Building Safety Fund:

• 170 buildings (21%) are remaining in the fund with developers set to reimburse the cost of remediation.
• Nine buildings (1%) are anticipated to be transferred to developers.

Of the 809 buildings proceeding with an application for funding, 181 buildings have been assessed with a Fire Risk Appraisal for External Walls (FRAEW), and 628 have been assessed under the BSF 2020 CAN criteria. It is possible for a building to submit a new application to the fund after having completed remediation, if it originally applied under the BSF 2020 CAN criteria. Therefore, buildings could be double counted. As of 31 December 2024 one building had undertaken remediation work from both application periods, so is double counted. Further details are available in the technical note.

Of the 809 buildings proceeding with an application for funding, 521 buildings (64%) have either started or completed remediation works – no change since the end of November.

Of the 521 buildings that have started or completed remediation as of 31 December 2024:

• 157 buildings (19% of all buildings) have started remediation.
• 364 buildings (45% of all buildings) have completed remediation – an increase of seven since the end of November. Of these, 229 buildings (28% of all buildings) have received building control sign off.

There are 288 eligible buildings proceeding with an application for funding that have not started remediation, of which:

• 143 (18% of all buildings) have remediation plans in place
• 145 (18% of all buildings) have reported an intent to remediate

There are an estimated 67,000 dwellings in buildings that are eligible and proceeding with an application for funding in the BSF.

BSF remediation progress over time

Figure 12: 35 more buildings proceeding with an application for funding in the BSF have started or completed remediation since the end of December 2023

Since the end of December 2023:

• 141 fewer eligible buildings are proceeding with an application for funding from the Building Safety Fund.
• 35 more eligible buildings have started or completed remediation, and 133 more eligible buildings have completed remediation.

BSF remediation by tenure

Figure 13: 65% of social sector buildings in the BSF, including buildings with a financial viability claim, have started or completed remediation compared to 64% of private sector buildings.

Social sector buildings receiving full government funding for their remediation due to financial viability claims were, up until May 2024, included in private sector buildings counts. Further detail is available in the accompanying technical note.

Cladding Safety Scheme

Information in this section is correct as at 31 December 2024 and shows a monthly update from the previous publication.

Figure 14: There are 2,940 buildings at different stages of the Cladding Safety Scheme, including 314 buildings with live applications and 525 eligible buildings, of which 53 buildings have started or completed works, with 17 having completed works.

Table 6: Remediation status for buildings within the Cladding Safety Scheme, 31 December 2024

Cladding Safety Scheme: key statistics

As at the end of December 2024, there were 2,940 buildings in the different stages of the Cladding Safety Scheme (525 eligible buildings and 2,415 pre-eligible buildings). Of the 2,415 pre-eligible buildings:

• 2,101 buildings are in the pre-application stage.
• 314 buildings have a live application and are progressing through the eligibility stages.

There are 525 eligible buildings as at the end of December 2024, an increase of 33 since the end of November. None of the newly eligible buildings this month have been transferred from the BSF. In total, 109 of the eligible buildings in the CSS have been transferred from the BSF.

Of the 525 eligible buildings:

• 499 buildings (95% of eligible buildings) have signed Grant Funding Agreements (GFA) - an increase of 35 since the end of November
• Of these, 331 buildings (63% of all eligible buildings) have received a pre-tender support payment – an increase of 18 since the end of November
• 53 buildings have started or completed remediation works on site – an increase of seven since the end of November
• Of these, 17 buildings have completed remediation works on site, including those awaiting building control sign-off – an increase of one since the end of November.

Four eligible buildings are in Northern Ireland, with the remainder in England.

Developer-led remediation

Information in this section received by developers is correct as at 31 October 2024, except for Frasers Developments, who did not submit data within the deadline. For this developer, the data reported in this release uses the data they submitted as at 31 July 2024. The information received by developers remains unchanged since the previous publication. Information in this section received from other programmes that relate to developer-led remediation (where cladding remediation is being carried out in a government funded remediation programme and the developer will subsequently pay for the works) is correct as at 31 December 2024.

The estimates in this section include some buildings which are also included in other sections of this data release e.g., those reported under the following sections: ‘ACM Remediation’, ‘Building Safety Fund’, ‘Cladding Safety Scheme’ and ‘Social Housing Sector’.

Figure 17: 49% of buildings in the developer remediation contract have either started or completed remediation works on life-critical fire safety risks, with 25% having completed remediation works.

Table 7: Remediation status of buildings requiring works under the developer remediation contract, 31 December 2024. Percentages may not sum to 100% due to rounding.

Developer remediation: key statistics

As at 31 December 2024, 54 developers have signed the developer remediation contract. Between them, there are 4,683 buildings covered by the developer remediation contract. Of which, there are 1,745 buildings identified as having life-critical fire safety risks that will be remediated by developers – a decrease of one since the November data release.

Of the 1,745 buildings identified as having life-critical fire safety risks:

• 439 (25%) are reported to have completed remediation– no change since the November data release. Of the 439 buildings that are reported to have completed remediation, 357 buildings (20% of all buildings with defects) are reported to have received building control sign-off.
• 850 (49%) are reported to have started or completed remediation – no change since the November data release.
• 430 (25%) are reported to have not started remediation but have plans in place – no change since the November data release.

Although information from developers is received quarterly, these statistics are subject to change and are updated monthly as information from other programmes which relate to remediation is updated monthly.

The 1,745 buildings identified as requiring remediation have an estimated cost of remediation of around £3.7 billion. This has not changed compared to the November data release.

There are an estimated 115,000 dwellings in buildings with defects that developers are committed to remediate. Of these, there are an estimated 59,000 dwellings in buildings that are reported as having either started or completed remediation works.

Based on start and completion dates reported by developers, 509 buildings which have not yet started are reportedly expected to start works between 1 November 2024 and 31 October 2025, and 284 buildings which have not yet completed are reportedly expected to complete their remediation between 1 November 2024 and 31 October 2025.

444 buildings have transferred from the Building Safety Fund to developers, an increase of one since the November data release:

• 46 (10%) have completed remediation - no change since the November data release. Of these 46, 32 buildings (7% of all buildings) are reported to have received building control sign-off.
• 167 (38%) have started or completed remediation – no change since the November data release.
• 126 (28%) are reported to have not started remediation but have plans in place - no change since the November data release.
• 63 (14%) are reported to have not started remediation and have no plans in place – no change since the November data release.
• 88 (20%) have not been identified by developers as having life-critical fire-safety defects – an increase of one since the November data release.

The 444 buildings in the developer remediation contract differs from the 455 reported in the Building Safety Fund section of the data release, due to developers defining buildings differently to in the Building Safety Fund. The same building structures are included in both sections of the release.

Height breakdown

Figure 18: 54% of the 18m+ buildings have started or completed remediation, compared to 42% of the 11-18m buildings.

Cladding defects

Some remediation being undertaken by developers on buildings with life-critical fire safety risks relate to non-cladding defects. When excluding buildings reported to have only non-cladding defects, there are 1,535 buildings which developers have reported as having unsafe cladding – a decrease of one since the November data release. Of these:

• 397 (26%) are reported to have completed remediation - no change since the November data release. Of these 397, 331 buildings (22% of all buildings with cladding defects) are reported to have received building control sign-off.
• 790 (51%) are reported to have started or completed remediation - no change since the November data release.
• 390 (25%) are reported to have not started remediation but have plans in place - no change since the November data release.

These estimates are subject to change each month due to the monitoring of buildings under the developer remediation contract in other remediation programmes.

Self-reported information

The figures reported for developers above combine information received directly from developers as well as information held by the department from other programmes which relate to remediation. This is to help better estimate a figure for buildings requiring remediation under the developer remediation contract. The figures reported above will also include buildings which are being remediated solely under a government remediation scheme, for which the developer will reimburse taxpayers.

The estimates in this section report on buildings which have been self-reported by developers as requiring remediation to life-critical fire safety risks. Furthermore, this section reports on buildings which are being remediated by the developer directly, rather than being remediated through a government fund and being reimbursed to taxpayers.

Developers have self-reported that 1,492 buildings require life-critical fire safety remediation, which will be directly remediated by the developer. Some of these buildings are being remediated in the BSF or ACM programme, however they are reported to have other non-EWS life-critical fire safety defects which are being remediated by the developer and are therefore included in these statistics. Of these 1,492 buildings being directly remediated by the developer:

• 292 buildings (20%) have completed remediation. Of these, 225 buildings (15% of all buildings with defects) are reported to have received building control sign-off.
• 652 buildings (44%) have started or completed remediation.
• 400 buildings (27%) have not started remediation but have a plan in place.

Further information on the progress developers have made regarding the buildings they’ve reported on is available in the accompanying management information tables.

Information in this section received by Registered Providers of Social Housing is correct as at 30 September 2024 and remains unchanged from the previous publication. Information in this section received from other programmes that relate to social housing is correct as at 31 December 2024.

The estimates in this section include some buildings which are also included in other sections of this data release e.g., those reported under the following sections: ‘ACM Remediation’, ‘Building Safety Fund’, ‘Cladding Safety Scheme’ and ‘Developer Remediation’.

From June 2024, the estimates in this section of the release include buildings which have been reported by Registered Providers to have completed remediation since 14 June 2017 but prior to the most recent assessment. They also include social buildings the department has identified in other remediation programmes as having unsafe cladding and are also being monitored in those programmes.

Figure 19: 45% of social buildings identified to have unsafe cladding have started or completed remediation works, with 28% (of identified buildings) having completed remediation works.

Remediation Stage	Number of buildings	Percentage	Cumulative Number	Cumulative Percentage
Remediation complete	665	26%	665	26%
Remediation complete – awaiting building control sign-off	63	2%	728	28%
Remediation started	448	17%	1176	45%
Remediation works planned	847	33%	2023	78%
Remediation plans unclear from survey	583	22%	2606	100%
Total	2606	100%	2606	100%

Social housing remediation: key statistics

564 registered providers of social housing were invited to respond to this round of a survey on their 11m+ stock. 935 small registered providers were excluded from this round of the survey because they had indicated that they were not the Responsible Entity for any 11m+ residential buildings.

As at 31 December 2024, 2,606 social buildings 11 metres and over in height have been identified as having life-critical fire-safety cladding defects – no change since the November data release. Of the 2,606 buildings identified with unsafe cladding:

• 1,992 were reported by Registered Providers to have unsafe cladding at the time of their most recent assessment. This could include buildings whose remediation work has been completed but await building control sign off and those awaiting a subsequent assessment to confirm no outstanding life-critical fire-safety defects. Additional information on these buildings is available in the accompanying management information tables, social housing provider release document and the Regulator for Social Housing’s publication on Fire safety remediation in social housing in England.
• 500 were reported by Registered Providers to have unsafe cladding since June 2017 but prior to the most recent assessment, which have since been remediated. Of these, 12 were reported by Registered Providers to have unsafe cladding in the previous survey (as at 30 June 2024) but have since completed remediation.
• 114 were identified under other remediation programmes (BSF, ACM, CSS or developer remediation) as having unsafe cladding and are also being monitored in those programmes.

Of the 2,606 buildings identified to have unsafe cladding:

• 728 buildings (28%) are reported to have completed remediation – no change since reported in the November data release. Of these 728, 665 (26% of all buildings with defects) are reported to have received building control sign-off  – no change since reported in the November data release.
• 1,176 buildings (45%) are reported to have started or completed remediation – no change since reported in the November data release.
• 847 buildings (33%) are reported to have not started remediation but have plans in place – an increase of two since reported in the November data release.

Although information from registered providers of social housing is received quarterly, these statistics will be updated monthly as information from other programmes which relate to social building remediation is updated monthly.

Height breakdown

Figure 20: 52% of the 18m+ social buildings identified to have unsafe cladding have started or completed remediation, compared to 38% of the 11-18m buildings.

Additional information available for individual social housing providers is available in the accompanying management information tables and social housing provider release document.

The estimates in this section exclude three buildings identified with unsafe cladding which have been decanted prior to demolition.

Social housing remediation: recent assessments

The estimates in this section include buildings self-reported by registered providers in the latest survey (as at 30 September 2024) as having unsafe cladding at the time of their most recent assessment.

Registered Providers reported that 2,492 have been found to have unsafe cladding since June 2017. Of these, 500 completed remediation prior to their most recent building works assessment and 1,992 buildings have been identified with unsafe cladding at the time of the most recent building works assessment. Of the 1,992 buildings:

• 144 buildings (7%) are reported to have completed remediation – no change since the November data release. Of these 144, 84 buildings (4% of all buildings with defects) are reported to have received building control sign-off.
• 589 buildings (30%) are reported to have started or completed remediation - no change since the November data release.
• 831 buildings (42%) are reported to have not started remediation but have plans in place – no change since the November data release.

Enforcement

Information in this section is correct as of 12th December 2024 and shows a monthly update from the previous publication.

This section includes local authority enforcement action on buildings 11 metres or over in height. Up until June 2024 only enforcement action taken on buildings over 18m in height was reported on.

Local authority enforcement action: key statistics

As of 12th December 2024, enforcement action has been, or is being, taken under the Housing Act against 506 buildings over 11m with unsafe cladding - an increase of seven since the end of November. Of these, 145 buildings have had 148 inspections with Joint Inspection Team support – an increase of three inspections since the end of November.

Of the 506 buildings where a local authority had undertaken an inspection, we are aware that:

• 112 had a Category 1 HHSRS rating
• 336 buildings had a Category 2 HHSRS rating

As several buildings have now had two or more inspections, from August 2024, only the most recent inspection’s category rating is reported on, as this is used to gauge the risks of the buildings in each Local Authority’s portfolio. Additional inspections are still reported as enforcement action.

Of the 506 buildings, we are aware that at least 172 improvement notices, 51 hazard awareness notices and 1 prohibition order have been served to date. Some buildings may have received multiple notices. We understand that 43 of the improvement notices have been subject to appeals.
