Two thousand homes. That is the scale of the West Midlands Combined Authority’s new Buildings Retrofit Pilot, a programme that will pay for insulation, heat pumps, and solar panels in low-income owner-occupied homes. It is a start, but against the region’s 1.5 million homes, it is a start measured in teaspoons.
As reported by the West Midlands Combined Authority, the pilot is funded by £7.5 million from the government’s Social Housing Decarbonisation Fund and local top-ups. But here is the catch: it only covers owner-occupiers on low incomes. Private tenants, social housing residents, and the vast majority of homeowners who cannot afford the upfront cost of a heat pump, they are left out.
Who qualifies, and who doesn’t
The pilot is open to homeowners in the West Midlands with a household income below £30,000 and an EPC rating of D or below. They get a full home survey, then a package of measures: cavity wall insulation, loft insulation, air source heat pumps, solar PV, and smart heating controls. No upfront cost. The authority estimates savings of £300–£400 a year on energy bills.
But the eligibility criteria are tight. You must own your home outright or have a mortgage. You cannot be in receipt of certain benefits that already trigger energy support. And the property must be a house, not a flat. The Energy Saving Trust notes that solid-wall homes, common in pre-1919 terraces across Birmingham and the Black Country, are excluded because the pilot focuses on cavity walls.
What it costs a typical 3-bed semi
For the homeowner, zero. For the taxpayer, the average cost per home is roughly £3,750. That covers survey, installation, and certification. Compare that with the typical cost of a full retrofit for a 3-bed semi: £10,000–£25,000 if you pay yourself, depending on whether you add a heat pump or just insulation. The pilot’s per-home figure is low because it prioritises cheaper fabric measures and bulk procurement.
But the real cost is the missed opportunity. Ofgem’s data shows that the West Midlands has the highest proportion of homes below EPC C in England, 63% of owner-occupied homes. The pilot will lift 2,000 homes to C or above. The remaining 1.1 million homes below C will stay cold and expensive to heat.
Why this matters for national policy
The West Midlands pilot is a template for what a national retrofit programme could look like: income-linked, area-based, and fully funded. But it also exposes the limits of piecemeal funding. The government’s own Heat and Buildings Strategy, published in 2021, called for 600,000 heat pump installations a year by 2028. The UK installed 55,000 last year. The gap is not a crack, it is a chasm.
What this misses is the sheer scale of the retrofit task. The Climate Change Committee says 19 million homes need upgrading by 2050. At the current rate of 50,000 deep retrofits a year, the UK will finish in 380 years. The West Midlands pilot is a well-designed scheme. But it is a pilot. The country needs a programme.
What you can do now
If you live in the West Midlands and meet the criteria, contact the WMCA directly, applications are open until 31 March 2026. For everyone else, check the Energy Saving Trust’s grant finder for local authority schemes in your area. The Great British Insulation Scheme closed on 31 March 2026. It funded insulation measures only and never covered windows or glazing. Apply via gov.uk. The window is open. The scale is small. But a pilot is still a start.
Frequently Asked Questions
The West Midlands Retrofit Pilot is for owner-occupiers with a household income below £30,000 and an EPC rating of D or below. You must own your home outright or have a mortgage, and the property must be a house (not a flat). Solid-wall homes are excluded as the scheme focuses on cavity walls.
A full retrofit for a typical 3-bed semi-detached house costs between £10,000 and £25,000 if you pay yourself, depending on whether you add a heat pump or just insulation. Under the West Midlands pilot, the average cost per home is £3,750, covering survey, installation, and certification.
The West Midlands pilot estimates savings of £300–£400 a year on energy bills for homes receiving insulation, heat pumps, and solar panels. Nationally, savings vary, but upgrading from an EPC D to C can cut annual heating costs by around £300–£500.
The government's Heat and Buildings Strategy aims for 600,000 heat pump installations per year by 2028. However, the UK installed only 55,000 last year. This shows a significant gap between targets and current progress.
The Climate Change Committee says 19 million homes need upgrading by 2050. At the current rate of 50,000 deep retrofits per year, it would take the UK 380 years to complete the task, showing the need for a much larger national programme.
