The minimum energy performance certificate rating for rental properties will rise to C by 2030, a move that could hit 1.2 million homes across England and Wales. That is the headline from a new government consultation, as reported by thefifthestate.com.au. For homeowners, the implications stretch beyond the rental sector, this signals a broader push on energy efficiency that will eventually touch owner-occupied homes too.
Who qualifies, and who doesn’t
The new rules apply to all private rented sector properties in England and Wales. Landlords must ensure their properties meet EPC C by 31 December 2030. The current minimum is E, so the jump is substantial. Around 1.2 million homes currently fall below C, according to government estimates. Exemptions exist for listed buildings, properties where the cost of upgrades exceeds £3,500, and those where tenants refuse consent. But the bar for exemption is high, landlords must prove they have exhausted all cost-effective measures.
What it costs a typical 3-bed semi
Upgrading a property from EPC E to C typically involves cavity wall insulation, loft insulation top-up, double glazing, and a modern boiler or heat pump. The Energy Saving Trust puts the cost at £5,000 to £15,000 depending on the property’s age and construction. A typical 3-bed semi from the 1930s might need £8,000 of work. Landlords can claim up to £5,000 per property under the Green Homes Grant scheme, though the scheme is currently capped at 60,000 applications. Those who fail to comply face fines of up to £30,000 per property, plus a potential ban on letting.
The catch, and what it misses
But the policy has a blind spot. It does not mandate heat pumps or solar panels, only fabric efficiency. A property can hit EPC C with a gas boiler and no renewables, so long as the walls and roof are well insulated. That means the carbon savings may be modest. Campaigners argue the government should align the minimum standard with net-zero targets, requiring heat pumps by 2035. Yet the consultation document makes no mention of fossil fuel heating. The risk is that landlords do the cheapest work to scrape a C rating, leaving tenants with high running costs from an old gas boiler.
What homeowners should do now
If you are a landlord, start by checking your EPC register entry. If it is below C, book an energy assessment now, the surveyor will identify the cheapest route to C. The Green Homes Grant is open now, but applications close on 31 March 2027. For owner-occupiers, the writing is on the wall: similar standards are coming for sales and mortgages within five years. Get ahead by insulating your loft to 270mm and sealing draughts. The average household saves £315 a year on heating bills after full insulation, according to Ofgem. That is money you can keep, not hand to the energy companies.
