Small social housing providers often manage some of the most complex homes to decarbonise, including traditional, solid-wall and heritage properties. Many organisations have limited internal resources and face challenges balancing regulatory compliance, heritage constraints, resident wellbeing, funding limitations and long-term net zero ambitions. They require practical retrofit pathways that could inform investment decisions and support future decarbonisation programmes.

‍

What we did

Energiesprong UK provided tailored support to 11 smaller housing associations of the G320 group to assess their housing stock and develop practical retrofit pathways. This was delivered via the Mayor of London's Zero Carbon Accelerator Programme (led by Mott Macdonald).

‍

Support included tailored 1:1 reports for each housing provider, as well as a public facing summary report covering the following:

‍

  • Portfolio and stock analysis
  • Development of tailored retrofit pathways
  • EPC and future Home Energy Model (HEM) readiness assessments
  • Guidance on using EPC data, including identification and resolution of inaccuracies
  • Advice on heat-pump-ready retrofit strategies
  • Planning and procurement guidance
  • Funding and investment planning support
  • Resident engagement and communications recommendations
  • Practical tools, templates, checklists and case studies to support implementation

What was achieved?

The project helped participating organisations better understand their stock, identify priority retrofit measures and align future investment planning with emerging policy requirements and net-zero objectives. Many of the housing providers mentioned they would present the report findings to their boards and will use them to inform investment decisions and future programmes.

Energiesprong UK's report outlined the various options that were open to the cooperative to improve thermal efficiency of our properties, assessed the impact of the various options and their value for money. The report will help us to plan works over the next four years and has given us insight into options that we would not otherwise known about or considered. Our experience of the project was positive and the final report will help us to develop a programme and plan how we will rise to the challenge of Net Zero within our heritage stock that presents unique issues.” - Brockley Tenants Cooperative
