What is happening on 24 May?
From 24 May 2026, European Union (Energy Performance of Buildings) Regulations will change the scales for Building Energy Rating (BER) certificates removing sub-categories (A1,A2, A3, B1, B2, B3, C1, C2, C3, D1, D2, E1,E2 ,F,G ) and replacing them with simplified A0, A B, C, D, E, F, G ratings. The regulations also introduce a new A0 category for the most energy efficient properties. This means that any BER certificates with a 'validity' date after the 24 May 2026 will be rated AO, A, B, C, D, E, F, G.
