Seven years of stop-start retrofit policy may finally be ending. The Federation of Master Builders (FMB) has welcomed new cabinet appointments as a ‘positive start for housing and retrofit’ as reported by the FMB. For the 19 million UK homes with an EPC rating of D or below, this is not a Westminster talking point, it is a signal that the machinery of government may finally treat retrofit as infrastructure, not a pilot scheme.
Who qualifies, and who doesn’t
The key change is a named minister responsible for retrofit and housing delivery. Previous governments buried retrofit under business, energy, or levelling-up departments. The result: 11 different grant schemes since 2010, each with different rules, income thresholds, and expiry dates. Homeowners who applied for the Green Homes Grant in 2021 are still waiting for vouchers. The new structure, if the FMB is correct, should mean a single point of accountability. That matters when you are deciding whether to insulate your loft this year or wait for a better deal.
What it costs a typical 3-bed semi
Typical costs for a full retrofit package, cavity wall insulation, loft top-up, double glazing, and an air-source heat pump, run between £12,000 and £18,000 for a 3-bed semi, according to Energy Saving Trust estimates. Current grants cover about 30–50% of that, but only if you meet income caps. The new ministerial team could expand eligibility to the ‘able-to-pay’ market, households earning over £40,000 who currently get nothing. That group spends £1,200 a year on gas alone. A 30% bill reduction from insulation and a heat pump would pay back within a decade.
The catch is timing
But the FMB’s welcome note comes with a warning. The industry can scale, there are 30,000 certified retrofit assessors and coordinators in the UK, but they need consistent demand. Every time a grant scheme closes early, small builders lay off staff and move to new-build work. Ofgem data shows that the Boiler Upgrade Scheme has been undersubscribed by 40% in some regions, not because households do not want heat pumps, but because the application process is opaque and the installer capacity is patchy. A minister who understands this, who has seen a cavity wall survey and knows the difference between a SAP calculation and an EPC, could be the difference between 600,000 heat pumps a year and the current 60,000.
What to do next
For now, homeowners should do three things. First, check your EPC on gov.uk. If it is below C, start getting quotes for insulation, not next year, this autumn. Second, write to your MP asking when the new minister’s retrofit roadmap will be published. Third, if you are on a standard variable tariff, fix your energy price now; the October cap rise is £63, but the real saving comes from using less. Retrofit policy may finally be serious, but your bills are not waiting for Whitehall to get organised.
Frequently Asked Questions
Not immediately, but a dedicated retrofit minister should lead to more stable, long-term funding schemes rather than short-lived pilots. Homeowners can expect clearer EPC targets and potentially expanded eligibility for grants, though no new funding has been announced yet.
Get an up-to-date EPC assessment, research local MCS-certified installers, and consider low-cost measures like loft insulation or draught-proofing. These steps improve your home's efficiency and position you to take advantage of future schemes without delay.
