Proposed energy efficiency requirements are set to reshape the UK rental landscape, with experts warning that millions of homes could face compliance challenges, creating what has been described as an “EPC time bomb”.
Approximately 2.9 million privately rented homes in England currently fall below an EPC rating of C, meaning upgrades will be necessary to meet future standards. Government projections indicate an average upgrade cost of around £5,400, with a maximum cap potentially reaching £10,000 per property.
The impact is expected to be particularly significant for smaller landlords, many of whom own only a limited number of properties. Rising mortgage costs, increasing regulatory demands and licensing requirements are already placing pressure on profitability.
For landlords with older properties, especially those constructed in the Victorian or early 20th-century periods, meeting EPC targets could require extensive improvements. These may include enhanced insulation, new heating systems, improved glazing and the addition of renewable energy technologies.
Experts suggest that the financial strain associated with these changes could lead to a reduction in rental supply, as some landlords opt to leave the market.
Jason Harris-Cohen, Managing Director at LandlordBuyer, said: “We’re increasingly hearing from landlords who are concerned about how future EPC requirements will affect their properties. For many owners, particularly those with older homes, the cost of reaching an EPC C rating can be substantial and may simply not be financially viable.”
He added that for landlords who are considering exiting the rental market, or wanting to sell a house with tenants, it can be a practical solution that avoids unnecessary disruption for tenants.
“Many landlords assume that selling a rental property automatically means asking tenants to leave first, but that isn’t always the case. In reality, properties can be sold with tenants still living in them, which can help avoid evictions and maintain stability for renters.”
Specialist buyers focusing on tenanted properties are becoming increasingly prominent, offering landlords a more streamlined sales process compared to traditional routes.
While the push for improved energy performance aims to modernise the housing sector, the cost and complexity of compliance may ultimately prompt a reassessment among landlords about their long-term involvement in the rental market.
