Sixty-eight per cent of private rental homes in England already have an EPC rating of D or below, according to government data. That is roughly 3.6 million households paying over the odds for heat that leaks through single-glazed windows, uninsulated lofts, and draughty walls. The latest news from Simply Business confirms that the deadline for landlords to reach an EPC C has slipped from 2028 to 2030. For the tenant in a cold flat in Manchester, that means at least two more winters shivering under blankets while the radiator struggles.
As reported by Simply Business, the delay gives landlords more breathing room to arrange financing and find installers. But the catch is that tenants foot the bill, literally. The Energy Saving Trust estimates that upgrading a typical D-rated home to C saves around £300 a year on energy bills. Over the two-year delay, that is £600 per household that could have been saved, or roughly £2.2bn across the entire private rented sector.
Who qualifies, and who doesn’t
The new deadline applies to all new tenancies and renewals from 2030, though the government has not yet confirmed whether existing tenancies will be exempt. What is clear is that the minimum standard of EPC E remains in place until then. Landlords who fail to meet EPC E can already be fined up to £5,000 by local authorities. Yet enforcement has been patchy: only 1,200 fines were issued in 2023, according to a Freedom of Information request by the Residential Landlords Association. The delay to C risks creating a two-tier system where proactive landlords invest now while others wait until the last minute.
What it costs a typical 3-bed semi
For a landlord with a 3-bed semi in the Midlands, moving from EPC D to C typically costs between £5,000 and £12,000, depending on the work needed. Cavity wall insulation runs £2,000–£3,000; loft insulation about £500; a new gas boiler around £2,500; and double glazing can push £5,000–£8,000. The Great British Insulation Scheme closed on 31 March 2026. It funded insulation measures only and never covered windows or glazing. Landlords can also use the Boiler Upgrade Scheme for heat pumps, which offers £7,500 off installation, but only if they replace a fossil fuel heating system.
How homeowners can use the delay
Homeowners who own their property outright have no EPC deadline looming, but the same logic applies: every year of delay is money lost to higher bills. The government’s own figures show that a home with EPC D uses 20% more energy than an identical C-rated home. At current price cap levels (24.5p/kWh for electricity, 6.24p/kWh for gas from October 2024), that difference is roughly £250–£350 a year for a 3-bed semi. Over a decade, that is £3,000 down the drain. The Great British Insulation Scheme closed on 31 March 2026. It funded insulation measures only and never covered windows or glazing. The Boiler Upgrade Scheme is also available to homeowners who want to switch to a heat pump before the deadline.
Yet the delay also creates a perverse incentive. Some landlords may now delay essential upgrades, leaving tenants in cold homes for longer. The charity National Energy Action has warned that fuel poverty in the private rented sector already affects 1.2 million households. Each extra year of delay pushes more families into the choice between heating and eating. The government has promised a further consultation on enforcement and exemptions, but has not set a date.
What to do now
If you are a landlord, start planning upgrades now rather than waiting for 2029. Get an EPC assessment (£60–£120) to see where you stand. If you are a tenant, check your property’s EPC on the government register (free online) and ask your landlord about planned improvements. If you are a homeowner, the same advice applies: book an EPC assessment and apply for a grant through the Energy Saving Trust’s postcode checker. The Boiler Upgrade Scheme closes to new applications on 31 March 2027, so there is a hard deadline for heat pump funding. Do not let the rental deadline delay fool you into thinking your own energy bills can wait.
