The government has proposed a minimum EPC rating of C for all rental properties by 2030. Here is what landlords in Lambeth, Wandsworth, and Southwark need to do now to stay ahead of the changes.
The rules around EPC ratings for rental properties are changing. If you are a landlord in South London - whether you let a single flat in Lambeth or manage a portfolio across Wandsworth and Southwark - the proposed 2030 changes mean you need to start planning now. This guide sets out where the regulations stand today, what is changing, and the practical steps you can take to protect your investment.
Under the current Minimum Energy Efficiency Standards (MEES), all privately rented properties in England must hold a valid EPC with a rating of E or above. This has applied to new tenancies since April 2018 and to all existing tenancies since April 2023. Landlords who let a property with an F or G rating without a registered exemption can face fines of between 2,000 and 30,000 pounds per property.
If you are unsure whether your EPC is still valid, it is worth checking the government register. An EPC is valid for 10 years from the date of issue - so a certificate obtained in 2015 has already expired. The EPC cost in London in 2025 for a landlord EPC starts from 79 pounds at Carn Energy - a small outlay that protects you from enforcement action.
The government has proposed raising the minimum EPC standard for rental properties to C. Under current proposals, the new requirement would apply to new tenancies first from 2028, then extend to all existing tenancies by 2030. While the legislation has not yet been finalised, the direction is clear. Landlords who wait for the law to change before acting may face rushed and expensive upgrade programmes at the worst possible time.
A property rated D or E today does not automatically meet the proposed C standard. Many South London properties - particularly Victorian terraces with solid walls or older converted flats - currently sit at D or E. Reaching a B or above by 2030 will require planned investment, and the earlier that process begins, the more cost-effective it is likely to be.
The private rental market in Lambeth, Wandsworth, and Southwark is among the most active in the country. A high proportion of rental stock in these boroughs consists of pre-1919 properties with solid walls, which are harder and more expensive to insulate than cavity wall properties. Many of these homes have older gas boilers, single-glazed sash windows, and limited loft insulation.
Landlords with EPC ratings of D or E today should treat 2025 as the time to act. A landlord EPC from Carn Energy includes a full breakdown of recommended improvements, their likely cost, and the rating each measure could achieve - giving you the information you need to plan ahead and budget appropriately.
An EPC is valid for 10 years. If your certificate was issued before 2015, it will need renewing. Even if your EPC is still technically valid, if improvements have been made since it was assessed, a new EPC will reflect those changes and may give a higher rating - worth having on record given the proposed 2030 changes.
The most practical steps for South London landlords are straightforward. First, confirm all your properties have a valid EPC - if any have expired or were never obtained, book an assessment promptly. Second, review the recommendations on each certificate and consider which improvements are most cost-effective for your property type. Third, if any properties are rated D or E, speak to a retrofit assessor about the most efficient route to a higher rating.
Government grant funding may be available to help with improvement costs, particularly for properties that qualify under ECO4 or the Great British Insulation Scheme. A PAS 2035 retrofit assessment is the starting point for accessing most grant schemes.
