Propertymark has analysed data from the latest English Housing Survey which shows in the eight years to 2020 the number of homes in the PRS with an EPC 'C' rating rose from 19% to 39%.
If that increase is replicated forward to 2028, it will rise to 60%.
The UK Government has yet to respond to a consultation it held in 2020 on how to improve the energy performance of the PRS. The draft strategy includes a ‘preferred policy scenario’ for new tenancies to have a valid EPC rating of 'C' or above by 2025, extending to all tenancies by 2028.
A Private Members’ Bill with the same requirements was introduced by Conservative MP Sir Roger Gale in May.
England’s 4.4m privately rented homes make up 19% of the country’s total housing stock, the second largest tenure, so will be vital in supporting the UK's 2050 net-zero target.
According to the English Housing Survey, 68% of housing association homes are currently rated at 'C' or above, compared to 61% of council homes and 42% of those owner-occupied.
Propertymark is calling for the UK Government to move away from a one-size-fits-all policy in favour of energy efficiency proposals that consider a property’s age, condition, and size rather than its tenure.
Propertymark’s Lagging Behind report highlights the variances in retrofitting costs based on individual characteristics and regional property values. It includes proposals for local councils to develop ‘one-stop shops’ to engage with landlords to find suitable methods to facilitate retrofit at pace which has also been recommended by stakeholders such as the Local Government Association.
Timothy Douglas, Head of Policy and Campaigns for Propertymark, said: “We knew it would be a huge challenge for the PRS to achieve the proposed 2028 target because the owners of rental properties will not directly benefit from lower energy bills, so where is their incentive? The data in the English Housing Survey shows just how far there is to go.
“The new UK Government should take heed of this projected shortfall if it is serious about net-zero, and against the backdrop of the huge sums of money, it has had to commit in the short-term to help householders with their rising bills amid the cost-of-living crisis.
“Our member agents are already seeing rental properties disappearing from the market for a variety of reasons and there is a real danger more could go with the EPC rating target hanging over them.
“Propertymark supports moves to improve the energy efficiency of property types and will continue to lobby for a national retrofit strategy with realistic, fair and achievable targets alongside dedicated, long-term grants that consider each property’s individual characteristics.”
