CEO letter re 2026/27 RSH data requirements (local authorities)

Published 11 March 2026

Applies to England

Dear Chief Executive

2026/27 RSH data requirements

I am writing to inform you of the arrangements for data collection in the coming year. Timely and accurate data submission is a cornerstone of the co-regulatory settlement and we rely on the information you supply us to ensure proportionate and risk-based regulation. I would therefore be grateful if this letter can be passed on to the appropriate person within your organisation.

From April 2026, we will be commencing our annual round of data collection from local authority registered providers (‘providers’) via the NROSH+ website.

Data returns

During 2026/27, all providers will be required to submit the following structured returns:

NROSH+ returns	Deadline
Local Authority Data Return (LADR) (allows us to regulate compliance with the Rent Standard.)	10 July 2026
Tenant Satisfaction Measures (TSM) Return (including all supporting documentation as specified in the guidance) Note: providers who own fewer than 1,000 units of social housing do not need to submit TSM Returns to us.	30 June 2026
Fire Safety Remediation Survey (FRS)	3 weeks after each quarter end (Q4 2025/26 is due 23 April 2026)

The annual LADR and TSM Returns are both included on the single data list and must be completed by all local authorities registered with us.^{[footnote 1]} In 2026/27, the exception under our current requirements is that providers who own fewer than 1,000 units of social housing do not need to submit TSM Returns to us.

We will let you know in good time if there are any changes or additions during the year to either the information you need to submit or to our deadlines.

Local Authority Data Return (LADR)

Under our current requirements, we expect all local authority registered providers to submit the LADR Return to us.

For 2026, we are including a set of voluntary pilot questions on stock condition to LADR to seek additional information on stock decency from LARPs and reduce the need for ad hoc data collection on these issues through inspections and other engagement.

These pilot questions focus on the outcomes of each provider’s most recent stock condition survey, and the basis for year-end DHS fails each provider reports as part of their Tenant Satisfaction Measures. This includes the number of units found to fail DHS at the point of inspection through the most recent stock condition survey, which may be different from DHS fails reported at year-end. We anticipate that any significant survey exercise fully assessing all four DHS criteria will normally identify some non-decent units at the point of inspection. It is important that providers retain and can supply such information.

Changes have been made to update terminology and to ensure the LADR continues to provide us with the data required to support our regulatory activity. A summary of these is provided in Annex A. Providers must ensure that the return is completed correctly in line with the LADR guidance.

Tenant Satisfaction Measures (TSM) Return

Under our current requirements, we expect all providers who own 1,000 or more units of social housing to submit the TSM Return to us.

To improve data quality there have been some minor changes to the TSM Return. A summary of these is provided in Annex A. Providers must ensure that the return is completed correctly and that all relevant supporting documents are submitted to us in accordance with the TSM Requirements and the TSM Return guidance. A short note summarising the requirements relating to your publication of TSM information and your submission of the TSM Return to us is provided in Annex B.

Please note that the requirements for your collection and calculation of the TSMs themselves have not changed.

Fire Safety Remediation Return (FRS)

We will continue to collect the FRS through the NROSH+ system during 2026/27. This return no longer includes the requirement to submit an accompanying building level spreadsheet. Instead, you must continue to record building level data on all your 11m+ buildings on the National Remediation System (NRS). See Annex A for additional information on FRS and NRS alignment.

The FRS will not automatically be allocated to providers who own fewer than 1,000 units of social housing, and who have confirmed to us in a previous FRS submission that they are not the responsible entity for any building of 11 metres or more in height (or which has five or more storeys). However, providers must notify us if they acquire a building which they should report within this survey.

For more information regarding all our returns and the changes for 2026/27, please refer to the notes enclosed with this letter.

Submitting data

As each return is launched it will be automatically added to the NROSH+ dashboards of providers from whom we require the return and notification emails will be sent to all active NROSH+ users.

Guidance materials will be released on NROSH+ as they become available. It is essential that guidance notes are reviewed before the completion of each return to take account of any new, moved or revised questions.

Please submit returns as early as possible within each of the survey periods and allow yourself sufficient time to raise any questions regarding your submissions.

User accounts

You must ensure that your organisation maintains at least one active user on the NROSH+ system in order that your organisation continues to receive notifications from the system. Full access users on the NROSH+ system are able to create and maintain users for your organisation. However, if you are having any difficulties, please contact our enquiries team (details in header).

Query resolution

We aim to respond to all queries within five working days. Please note that queries made to us within five working days of a survey deadline may not receive a response until after the deadline has passed. This may result in submissions which do not meet the survey deadline. Extensions to deadlines will not be granted due to late queries.

During the checking of submissions, we may contact some providers to discuss their data returns before signing them off for further analysis. Subsequently, we may contact a minority of providers where there are any regulatory issues arising from this analysis of the validated data.

Additionally, we remind you that it is your responsibility to correctly categorise and record stock accurately according to the latest applicable legislation and to ensure you understand and apply the rent (and any other) rules correctly.

Organisational and contact details

The NROSH+ website requires your organisation to enter and maintain a suite of organisational and contact details. It is the responsibility of each individual provider to ensure that this contact information is kept updated and accurate throughout the year. This is important because we use this information to contact your organisation on regulatory matters.

It is very important that the organisational and contact details in NROSH+ are kept accurate and up to date by your officers. If they are not:

• your organisation may not receive important information on statutory consultations and/ or regulatory requirements; and/ or

• correspondence (which may include information about the provider’s business or regulatory compliance) may be sent to the wrong individuals (who in some cases may no longer work for the provider).

We take our duties in relation to data protection seriously but to do this we rely on providers updating their contact information in a timely fashion. Please see our privacy notice on the NROSH+ site for more details.

We now have a data sharing agreement in place with MHCLG to routinely provide up to date contact details for public task purposes for local authority providers. In addition to our privacy notice on the NROSH+ site, please also see MHCLG’s privacy notice for details.

If you have any queries, please refer to the guidance and FAQs on the NROSH+ website. If further assistance is required, you can contact the referrals and regulatory enquiries team NROSHenquiries@rsh.gov.uk who will assist you with your query.

Yours faithfully,

Will Perry

Director of Strategy
