Funding routes
Most retrofit money now reaches homes through councils and social landlords. We deliver the measures and the paperwork each route asks for.
For social landlords upgrading their own stock
Wave 3 grant runs to 31 March 2028 and every home must reach EPC band C. It funds insulation, windows and doors, heat pumps, solar PV and, alongside solar, batteries, with each measure installed by a TrustMark registered installer certified for it.
Delivered by councils, for private homes
£500m through councils from April 2025 to March 2028, for lower income households in owner occupied and privately rented homes rated EPC D to G. Finding and signing up households is often part of the job, as it was on the York programme.
Stock investment and frameworks
Social rented homes must meet EPC C on one of three measures, fabric, heating system or smart readiness, by 1 April 2030. Planned investment and framework programmes, often alongside a grant, are how most landlords will get there.
Schemes our team has delivered under: Social Housing Decarbonisation Fund wave 2 (North Star Housing), Home Upgrade Grant phase 2 (City of York Council), Green Homes Grant Local Authority Delivery phase 2 (Durham County Council), and council framework programmes (Kirklees Council).
From 2027/28 the government intends to merge the Social Housing Fund and the Local Grant into a single, area based scheme. ECO4 runs to 31 December 2026 and the Great British Insulation Scheme has closed. Rules and deadlines change as rounds open and close, so we confirm the current position for your programme before anything is priced. Checked 19 October 2026 against the published scheme guidance.
The whole house approach
Each home gets the package that lifts it furthest, not one measure dropped in on its own. Ventilate first so it stays healthy, insulate, then size the heating for the house it has become.
Every property assessed and designed under PAS 2035, with a ventilation strategy, before a measure is specified.
Designed in before the insulation goes on, so the warmer home stays dry. The front line on damp and mould under Awaab’s Law.
Cut the heat the home needs, roof down to floor.
Windows, doors and roofs detailed with the insulation, not around it.
Heating sized to the new heat demand, then solar PV and storage on the roofs that suit it.

Social housing retrofit happens around people living in the homes. That means planning access with the landlord, keeping residents told what is happening and when, and leaving every room safe and clean at the end of each day.
“Both worked extremely hard even staying late to make sure the rooms were all safe and clean before they left.”Martin P., internal wall insulation in Bath, on Google
How a programme runs
The same sequence on a single block or a thousand homes, so the retrofit coordinator, the funder and the residents always know what happens next.
Send us the stock, the measures and the funding route. We come back with questions, not a brochure.
Every property surveyed in person and photographed, measure by measure, before anything is priced.
A competent, compliant workforce and an office team who handle resident liaison, sequenced with your other trades.
Occupied homes, residents at home. Photographs before, during and after on every property.
A file for the coordinator and the funder: photographs, certificates, guarantees and lodgement evidence.

Every credential has a number, a scope and an expiry date, and you can check each one yourself. We say what each covers rather than waving a logo.

Yes. We work directly for housing providers and councils, and as a subcontractor to main contractors. Our team has delivered for Aspire Housing, North Star Housing, Durham County Council, City of York Council and Kirklees Council, among others.
Warm Homes: Social Housing Fund and Warm Homes: Local Grant programmes, council and landlord capital programmes, and framework call offs. Our team has also delivered under the Social Housing Decarbonisation Fund, the Home Upgrade Grant and the Green Homes Grant Local Authority Delivery scheme.
On whole house programmes we can run retrofit assessment and coordination with our own people, as we did for Aspire Housing, or work to the design of the retrofit coordinator you have appointed. Either way you get photographs at every stage and a file at handover you can audit.
PAS 2030:2023 for flat roof insulation (measure B5), TrustMark registration, MCS certification for solar PV and battery storage, Gas Safe registration for domestic gas work, and accreditation to issue insurance backed guarantees through Bluedrop. Numbers, scopes and expiry dates are on our supplier information page.
Funded programmes need every measure installed by a TrustMark registered business certified for that measure: PAS 2030 for fabric measures, MCS for solar PV, batteries and heat pumps. PAS 2030 is held measure by measure, and ours covers flat roof insulation. Before we price, we set out how each measure on your programme will be certified, including where we install under the main contractor’s certification.
Each social rented home in England must reach EPC C on one of three measures by 1 April 2030, enforced through the Decent Homes Standard. Fabric first packages are usually the most reliable way to get there, and we can help you sequence the homes that are furthest away.
As standard. Residents stay in, access is planned with the landlord, and resident liaison sits with the office team rather than with whoever is on site that day.
Across England and Wales, from our head office in Clitheroe and offices in Manchester and London. Our map shows programmes from Birmingham to Northumberland.
Yes. Main contractors use us for single measure packages such as flat roofs, internal wall insulation and rooms in roof. Our sub contracting page sets out how that works.
The number of homes and their addresses or postcodes, the property types, the measures you have in mind, the funding route and the timescale. A stock list is enough to start; we survey before we commit to a price.
