What EPC rating is required for a rental property in 2026?
In England, rental properties must have a minimum EPC rating of E to be let legally in 2026. Properties rated F or G cannot be let unless a valid exemption is registered (e.g. the GBP 3,500 improvement cost cap has been reached). The proposed upgrade to a minimum C rating has been delayed beyond 2028 -- check gov.uk for current timelines.
Full answer
Energy Performance Certificate (EPC) ratings are mandatory for rental properties in the UK. The rating runs from A (most efficient) to G (least efficient), based on an assessment of the property's energy use and carbon emissions. Current requirement in England and Wales (2026): landlords must have a valid EPC with a minimum E rating before granting a new tenancy or renewing an existing one. Properties rated F or G cannot legally be let unless the landlord has registered a valid exemption with the PRS Exemptions Register. Failure to comply can result in a penalty of up to GBP 5,000 per property for breaches of up to 3 months, or GBP 5,000 for breaches over 3 months (in Wales up to GBP 4,000). Exemptions: an exemption can be registered if all recommended improvements have been made and the property still does not reach E; if the cost of improvements exceeds GBP 3,500 (the cost cap) and the property has not reached E; if the property is a listed building where improvements would alter character or appearance; or if a third-party (e.g. a tenant) refuses consent to improvements. Exemptions last 5 years. Proposed changes (as of 2026): the previous government proposed requiring all new tenancies to have an EPC C or above by 2028, and all existing tenancies by 2030. The current government has indicated a revised timeline -- the minimum C requirement has been delayed. The proposed cost cap for achieving C was GBP 10,000 per property. Always verify the current deadline at gov.uk/energy-performance-certificates before planning property improvements. Scotland: since 2025, rented homes must meet the Energy Efficiency Standard for Social Housing (EESSH2) or equivalent private rented sector standards -- check the Scottish Government website for current requirements. Wales: the Minimum Energy Efficiency Standards apply similarly to England, with the E minimum in force. Improvement options to raise EPC rating: loft insulation, cavity wall insulation, double glazing, heat pump or boiler upgrade, solar panels. Many improvements may be partially funded through government schemes such as the ECO4 scheme or the Great British Insulation Scheme.
