City Science Corporation Limited

Project title: Buy­to­Let Decarbonisation System
Grant value: £1,517,988.27

Partners: City Science, Property Master, PM Data Services

Project summary

The City Science and Property Master pilot tested a new digital platform, branded as eco-Landlord, designed to support buy-to-let landlords in retrofitting properties to improve energy efficiency. 

The Green Home Finance Accelerator supported the development of a full technology stack and user portals for landlords, brokers, and installers, including: 

• AI-driven retrofit planning: The system used AI models to suggest upgrade packages (e.g., insulation, heating systems) based on energy performance certificate (EPC) data, landlord motivations, and budget. These AI features allowed landlords to simulate how different retrofit measures would affect EPC ratings, offering more dynamic insights than static EPC advice. 
• finance matching: The platform included a bespoke mortgage calculator based on capabilities licensed from Property Master, allowing landlords to estimate borrowing potential for retrofit works. Users could then submit enquiries to a panel of Financial Conduct Authority (FCA)-regulated mortgage brokers for personalised advice. 
• installer onboarding and verification: Installers were manually vetted for registration with key industry bodies (e.g., MCS, Gas Safe, TrustMark). No installer was permitted to engage with landlords until these checks were complete.  
• end-to-end platform development: A cloud-hosted web portal (eco-landlord.com) served as the single access point. It was supported by automated property onboarding (using Land Registry, Companies House, and EPC data), a Customer Relationship Management system, and integrated portals for brokers and installers.

E.ON Energy Solutions Ltd

Project title: E.ON’s optimised Energy as a Service
Grant value: £1,056,977.31

Partners: E.ON Energy Solutions Ltd, Heatio Ltd, Energy Systems Catapult, Hometree Finance

Project summary

E.ON’s Energy as a Service (EaaS) pilot tested an innovative way for homeowners to adopt low-carbon technologies through a managed end-to-end service and flexible finance model. 

Green Home Finance Accelerator funding was used to develop a number of innovative tools and technologies to enhance the end-to-end consumer service offer: 

• The Heatio Home Energy Score: A personalised metric, from 0 to 999, generated using Heatio’s Building Physics Model and a reference database of over one million UK property archetypes. This tool used real smart meter data, regional weather information, and occupancy patterns to forecast energy use and identify cost-saving opportunities. 
• The Remote Home Assessment: Customers were invited to connect their smart meters to the Heatio platform. This enabled an initial remote assessment using data-driven modelling and a live digital twin of their home. Customers were then offered a tailored video consultation to explore options, with follow-up remote surveys identifying where equipment like heat pumps, batteries and solar panels could be installed. 
• the pre-fabricated ‘Energy Pod’: To reduce disruption, Heatio developed a modular Energy Pod (a prefabricated unit combining hot water and energy storage systems from Sunamp and GivEnergy). All mechanical and electrical work was completed in a factory setting, minimising on-site time and enabling rapid installation. This approach demonstrated how factory pre-configuration could reduce customer costs and make installations easier to scale. 
• customer engagement tools: Marketing campaigns were developed and delivered, centring on financial empowerment and control. Customers were guided step-by-step through the retrofit journey using plain-English tools and remote consultations, with messaging refined through live A/B testing to maximise engagement. 
• post-installation monitoring: Once technologies were installed, they were connected to the Heatio platform. This enabled real-time tracking of electricity and gas use, validation of predicted savings, and ongoing optimisation.

Energy Saving Trust Enterprises Limited 

Project title: Retrofit Proposition Toolkit
Grant value: £829,204.02

Partners: Energy Saving Trust, TrustMark and Residential Logbook Association (via Chimni).

Project summary

Energy Saving Trust led the development and testing of the Retrofit Proposition Toolkit (RPT), an integrated set of digital services designed to help lenders offer end-to-end retrofit journeys to their customers. 

Funding from the GHFA Pilot Phase supported the development, integration and testing of the following core Retrofit Proposition Toolkit components: 

• property data lookup service: Powered by Energy Saving Trust’s Home Analytics API, this service lets users get tailored insights by simply entering their postcode and address. It automatically retrieves and displays key data such as property type, heating system and insulation levels. 
• tailored energy-saving advice: The Home Energy Check API generates improvement recommendations based on the user’s home, budget, and motivations (e.g. saving money or cutting carbon). This allows customers to explore retrofit options with personalised cost, carbon and energy performance certificate (EPC) impacts. 
• digital logbook integration: The digital logbook is a centralised, online record of a home’s key property data, retrofit history, and renovation plans. Users can create a digital logbook through Chimni, a consortium partner specialising in home management tools, which automatically imports their retrofit action plan and helps them track progress over time. This offers a secure, portable record of home upgrades. 
• installer search functionality: Users can view and filter a list of local TrustMark-registered installers based on the measures they’re interested in (e.g. loft insulation or heat pumps). This makes it easier to find a vetted professional to carry out the work. 
• installation verification service: Lenders can confirm that recommended upgrades have been completed using TrustMark’s assurance tools, such as the Trustmark Data Warehouse API (which provides access to verified records of completed retrofit installations). This supports compliance with the Consumer Credit Act and the Financial Conduct Authority’s Consumer Duty requirements. 
• user testing and interface design: A clean, accessible user interface was developed and tested with 10 participants (five homeowners and five landlords), helping refine the journey and ensuring it met users’ needs and expectations.

Living Places Earth Ltd

Project title: Built Environment Investment Analysis Service
Grant value: £887,239.65

Partners: Living Places Earth Ltd, SkenarioLabs, Eunomia Research, Consulting Ltd

Project summary

The Built Environment Investment Analysis Service, piloted by Living Places, developed two tools to provide mortgage providers and local authorities with comprehensive data insights to facilitate greater investment in green home retrofit.

Green Home Finance Accelerator funding was used to develop the two tools, enhance usability and tailor insights to specific user needs. Whilst described as two separate tools, both were built on the same core back-end, with front-ends designed to be most appropriate to each target user group, maximising potential engagement. Funding was used to develop, test and integrate the following features: 

Lender tool: 

• portfolio segmentation: Enables lenders to analyse climate risks at different levels (e.g., property type, location, Energy Performance Certificate ratings, mortgage product categories). Using the tool mortgage lenders can, for example, analyse climate risk in their mortgage book according to a specific property type.  
• risk scoring and threshold customisation: Enables lenders to set their own climate risk thresholds and receive property-specific information on high-risk properties.  
• retrofit pathway modelling: Enables lenders to adjust assumptions to model investment scenarios for different retrofit pathways and associated lending criteria. Different retrofit pathways can comprise varying levels of energy efficiency improvements and low-carbon technology installation across a portfolio.  

Local Authority tool: 

• project area comparison: Enables local authorities to create and edit different Net Zero Neighbourhood proposals and compare them to create various delivery options.  
• spatial data mapping: Enables users to filter assessments by neighbourhoods, housing characteristics or socio-economic factors. This required the application of predictive modelling to evaluate assets without current Energy Performance Certificates and predict their energy efficiency.  
• retrofit scenarios: Allows specific retrofit scenarios to be applied, enables users to compare impacts of different levels of retrofit, and includes deep retrofit, electrification of heat, and solar/battery.

Green Home Finance Accelerator funding enabled a wide range of project activities designed to pilot, support and scale retrofit finance through credit unions, including:  

• developing two retrofit loan products: the Better Home Loan and One Stop Shop loan.  
• improving both householder and credit union understanding of retrofit by creating householder advice materials (e.g. 10 user-friendly factsheets). 
• designing and delivering Credit Union staff training in person with Metro Moneywise Credit Union and South Manchester Credit Union and via the Association of British Credit Unions’ (ABCUL) platform.  
• developing and integrating tools that verify energy reductions post-retrofit, such as Carbon Co-op’s PowerShaper Monitor and Tracker, which onboards clients to smart meter-based tools to quantify energy use and savings. 
• market research with a survey of credit union members to understand retrofit motivations with 145 responses coming from eight community credit unions. 
• disseminating findings through ABCUL and national networks to raise awareness of retrofit within the credit union sector and vice versa and to share best practice and raise the profile of credit unions as a lender of choice for retrofit with policy makers and local authorities. 
• planning for a Credit Union Support Organisation (CUSO) to coordinate efforts to provide a community retrofit finance model on a larger scale. CUSOs are owned by multiple credit unions and offer a range of back-office and other services. They can help credit unions access sophisticated services, leading to cost savings, increased efficiency and the development of new services.

Perenna Bank PLC

Project title: Perenna Retrofit Mortgage & HEMS
Grant value: £888,465.25

Partners: Perenna Bank PLC, Heatio, Energy Systems Catapult

Project summary

Perenna piloted a new green mortgage feature designed to encourage home retrofitting. The retrofit discount feature offered customers a 0.20% reduction on their long-term fixed-rate mortgage if they installed solar panels or a heat pump within two years of remortgaging. 

Green Home Finance Accelerator funded activities included:  

• behavioural research: Energy Systems Catapult conducted qualitative interviews with 20 mortgage brokers and 16 consumers. The project also surveyed 2,208 people during the pilot phase across a range of ages and income levels. The research tested whether the retrofit discount would change attitudes or increase the likelihood of installing green technology, and helped to inform the design of the discount feature. 
• mortgage discount feature: Perenna created a digital process allowing eligible customers to opt in to a 0.20% mortgage discount. To qualify, customers must commit to installing solar panels (minimum 2kWp) or a heat pump within two years, using an MCS-certified installer. Savings are then applied to the full mortgage loan for the remainder of its term. For example, a customer borrowing £300,000 could save £480 per year on mortgage payments, excluding energy savings. 
• customer journey and verification process: The customer journey was designed to be simple and flexible. Homeowners could choose their own installer or use links provided by Perenna to MCS-certified contractors. Once the retrofit was complete, customers submitted their installer’s certification number. Perenna verified this through an automated link to the MCS database (a national system that certifies clean energy installations). 
• educational content and marketing tools: Perenna launched landing pages, digital calculators, downloadable guides and blog content to explain how the retrofit feature worked. Consumer testing of the website throughout the project led to improvements including key messages being reworded and bolded after surveys showed that many users missed basic eligibility criteria. 
• Heatio platform access: Homeowners had the option to engage with Heatio, whose digital Home Energy Management System helps assess energy use and identify suitable retrofits. Heatio signed up 116 users during the pilot phase outside of the project, with 63 fully onboarded using smart meters.

Scroll Finance Limited

Project title: Point-of-Sale Technology for Financing Retrofits and Energy Efficiency (POST-FREE)
Grant value: £1,773,014.27

Partners: Scroll Finance (Scroll, project lead and fintech lender); Sustainable Building Services (UK) Ltd. (SBS, retrofit contractor and consortium partner); Sustainable Energy Services (SES, retrofit advice and engagement specialist and consortium partner)

Project summary

The POST-FREE (Point-of-Sale Technology for Financing Retrofits and Energy Efficiency) pilot brought together Scroll Finance, Sustainable Building Services (SBS), and Sustainable Energy Services (SES) to create an integrated retrofit solution for private homeowners and landlords. 

Green Home Finance Accelerator funding was used to develop:  

• the Green Finance Hub: A digital  finance platform that integrates with the retrofit journey. This included creating the core lending infrastructure for secured loans and integrations with lenders and brokers, digital tools including a digital pre-application form, interactive finance calculators, and landing pages to provide customers with digestible information and tools to calculate monthly payments, check eligibility, and perform credit checks, all tailored for use with retrofit measures. 
• the Home Hero advice service and retrofit tools: Launched to be a new consumer-facing brand and website (Home Hero, run by SES) to engage homeowners. Under Home Hero, the project delivered free home energy assessments and PAS:2035-compliant retrofit advice. 
• multi-channel marketing and outreach: A comprehensive marketing campaign was launched to drive homeowner engagement in the pilot regions. The project carried out targeted digital advertising (e.g. Facebook/Meta and Google ads aimed at homeowners aged 35-65 in the chosen areas) and local offline marketing, such as scaffold banners, letter drops and flyers, all leveraging SBS’ local presence.  
• partner integration and compliance setup:The POST-FREE project trained and enabled pilot partners to access the finance offering. Many delivery partners (e.g. retrofit installers and advisors) were not regulated by the Financial Conduct Authority (FCA) at the time, so the project produced standard scripts, training modules, and referral protocols so they could introduce the loan option in a compliant manner.

Scroll Finance Limited

Project title: Green Line of Credit Embedded in Retrofit Services (GLOCERS Project)
Grant value: £1,551,642.75

Partners: Scroll Finance (lead organisation); SuSy (Sustainable Systems) – digital retrofit platform (partnered with Retrofit West in Bristol); Furbnow – full-service retrofit provider (West Midlands); Cosy Homes Oxfordshire – one-stop retrofit service (Oxfordshire); and premium solar PV and battery installers (Artisan Electric, HSEnergy, Project Solar).

Project summary

The GLOCERS project aimed to pilot an innovative financial product - Green Home Equity Line of Credit (Green HELOC) – to help homeowners affordably and flexibly finance home retrofits. 

Green Home Finance Accelerator funding was used to deliver:  

• development of the Green HELOC product and lending platform: Funding supported the adaptation of Scroll’s existing home-equity loan and line of credit model to meet the needs of retrofit projects. This included designing key product features, such as ring-fenced funds for approved works and an interest-only draw down period, and building the underlying digital infrastructure for loan applications, credit checks, and processing. 
• creation of digital integration tools for pilot partners: The project developed user-friendly digital tools to enable seamless finance integration within partner organisations’ platforms. This included dedicated landing pages for each pilot partner’s customers, interactive finance calculators to show indicative loan terms, and pre-application forms to capture leads and check basic eligibility. 
• upgrade and white-labelling of SuSy’s retrofit advice platform: Funding enabled the transition of SuSy’s retrofit advice tool from a standalone mobile app to a web-based platform. This transition was due to user research and feedback on mobile apps which found that many users find downloading an app to be too high a barrier to entry. It also covered development work to allow partners (such as Retrofit West) to deploy the tool under their own branding, making it more accessible and trusted for local users. 
• design and testing of four distinct delivery models: Funding enabled Scroll Finance and partners to test the Green HELOC across four retrofit delivery routes: a digital advice tool (SuSy/Retrofit West in Bristol); a full-service retrofit provider (Furbnow in the West Midlands); a community-based one-stop shop (Cosy Homes Oxfordshire); and solar PV and battery installation firms (Artisan Electric, HSEnergy, and Project Solar). Each model involved co-development of finance referral journeys, integration of digital tools, and tailored partner training to reflect the specific needs of each delivery context. 
• marketing and outreach campaigns: The project delivered coordinated marketing activity across all four pilot areas, including targeted digital advertising (e.g. Facebook/Meta and Google Ads), educational email campaigns, and printed promotional materials. Messaging was tailored by partner and delivery model to test what resonated best with different audiences. For example, the most effective Meta ad used by Furbnow generated 946 leads at a cost of just £2.42 per lead, demonstrating that emotionally resonant messaging - e.g., “tired of cold rooms?” - significantly outperformed generic energy advice. 
• partner training and compliance setup: Since many delivery partners (installers, retrofit advisors) were not regulated by the Financial Conduct Authority (FCA), Green Home Finance Accelerator support was used to establish a compliance process for them to offer the finance referral. The project created standardised and compliant onboarding and training materials, so partners knew how to introduce the finance option appropriately and in compliance with FCA rules.
