Citizen – SHDF Wave 2.1

Coventry, England

Project Value: £19.2m

Introduction

Featuring 653 occupied homes in Coventry, this multi-measure decarbonisation scheme was delivered on behalf of leading social housing provider, Citizen. The £19.2m scheme was funded by the Social Housing Decarbonisation Fund Wave 2.1, following the successful completion of an earlier scheme for Citizen. That previous scheme involved retrofit works to 114 non-traditional properties.

This more recent scheme aimed to improve the energy efficiency of various solid-walled property archetypes. In so doing, it also sought to reduce energy costs for nearly 1,600 people and to reduce associated CO₂ emissions.

The Project

The Wave 2.1-funded project began in September 2023 and was completed in June 2025 as scheduled. It entailed installing multiple decarbonisation measures, all in accordance with PAS 2030/2035 standards. Adhering to best practice, and a fabric-first approach, it included improving the thermal performance of the homes by installing external wall insulation, and fitting new, energy-efficient double-glazed windows and doors. Some properties also benefited from the installation of new or top-up loft insulation.

Results

SBS has well-proven systems and methodologies for delivering decarbonisation works at scale. Those include early engagement with designers and other stakeholders to enable rapid mobilisation, and a shared approach to project-reporting and problem-solving.

The project ultimately achieved its stated objectives. On completion, the total calculated energy savings were estimated at 4,375,800 kwh/year, and the total carbon savings amounted to 1,193,400 kg/year (CO₂). All properties achieved an EPC rating of C or above.

The social impacts of the works included hundreds of families enjoying better living conditions, and support for 93 full-time and part-time jobs within the local supply chain.

Client Feedback

Bridget Guilfoyle, director of asset management at Citizen, said: “People are at the heart of everything we do, so its hugely rewarding to see and hear about the differences these energy efficiency measures are making to our customers.

“At Citizen we are committed to working with our partners to make a positive difference to our customers and communities – and we are looking forward to carrying out more energy efficiency works across the West Midlands.”
