Sustainable Building Services is one of the UK’s largest providers of retrofit residential decarbonisation works. Working with social housing and private residential property, we manage and deliver large-scale energy efficiency, low-carbon technology and whole-house retrofit schemes to MCS / PAS 2030 and PAS 2035 Standards.
Experience spanning decades
We were one of the first UK contractors to deliver PAS 2035-compliant schemes at scale, and to take an area-based approach, blending funding across mixed-tenures to maximise impact across communities.
Our work improves the health, comfort and well-being of thousands of mixed-tenure households each year. It also addresses issues relating to fuel-poverty and the cost-of-living crisis, while helping to reduce energy consumption and carbon emissions. All of this supports the UK’s progress towards meeting net zero targets.

Warm Homes: Social Housing Fund (WH: SHF)
As one of the UK’s most experienced tier 1 decarbonisation contractors, we have experience in supporting registered providers of social housing, successfully delivering SHDF/LAD/HUG projects between £1m - £25+ million.
We are one of only a few contractors to have delivered under all previous SHDF phases - from Demonstrator through to Wave 2.2 - improving the lives of over 17,000 people across projects totalling £170m.
Warm Homes: Local Grant (WH: LG)
Warm Homes: Local Grant provides local authorities in England an opportunity to make large scale energy efficiency improvements to households. This could be managed and delivered in conjunction with, or separately, to Warm Homes: Social Housing Fund (WH:SHF).
As a partner, we can manage all or as many aspects of the customer journey as required, providing an end-to-end retrofit journey and solution, including customer acquisition, retrofit advice, energy surveys (assessments), direct installation of measures, and customer/LA/WH:LG administration and reporting.
Excellence in Retrofit
We deliver projects through all decarbonisation and energy efficiency / low-carbon funding streams. Where possible, we blend funding on a project-by-project and/or dwelling-by-dwelling basis, to increase uptake and maximise impact across an area or region:
- Social Housing Decarbonisation Fund (SHDF)
- Home Upgrade Grant (HUG)
- Energy Company Obligation (ECO)
- Client funded projects
As a turnkey provider, we can take responsibility for the end-to-end retrofit journey. We provide surety to clients and stakeholders that all aspects and stages of their decarbonisation projects will be delivered in compliance with TrustMark requirements and the demands of specific funding schemes.
In addition to retrofit decarbonisation project delivery, our services include stock / asset and funding management, mixed tenure / private home acquisition, retrofit assessment / coordination / design services, and EEM / MCS installation.
We work with many clients, including:
Collaboration and Expertise
Our approach to decarbonisation project management is based around full collaboration; working in partnership with project stakeholders. This is crucial when developing, planning, managing and delivering decarbonisation projects at scale.
To support this approach, we have specifically developed a network of trusted suppliers and partners, including PAS 2035 service providers and energy efficiency / low-carbon technology installers. They complement our in-house capacity and capabilities, enabling us to mobilise retrofit projects within industry-leading timeframes.
This also allows us to support, identify and maximise funding for clients whilst, importantly, ensuring projects are delivered in compliance with standards, funding requirements and deadlines.
Award Success
The Unlock Net Zero Awards recognise and champion progress on the journey to decarbonisation for the UK housing, built environment and property sectors together with the professional services and supply chains that support them. We were awarded the Supply Chain Partner of the Year 2024 and won Collaboration of the Year 2024 for our retrofit decarbonisation work with Rykneld Homes. Our Owner & Chairman, Derek Horrocks was recognised as the Climate Champion of the Year 2024.
We have also been shortlisted for the Construction News Awards for its Contractor of the Year 2024. Recognised as one of the most prestigious and coveted awards in UK construction, we have been singled out among a select few peers for our dedication to high quality, people first operations, innovation, and the delivery of outstanding projects and a forward-looking approach to the industry.
