Haven offers customers a lower rate of interest for going green if you are buying, moving to, or building a high energy-rated home. Our Green 4-year Fixed Rate mortgage offers a lower rate of interest for homes with a certified Building Energy Rating (BER) between A1-B3 or if the 'validity' date on your BER Certificate is after 24 May 2026, your property will need to have a rating of A0, A or B.
Available to PDH customers who are either a First Time Buyer, Movers, Switcher (switching a mortgage to us where you live in the property), building their own home, buying a holiday home (in Ireland that you intend to live in), topping-up on an existing mortgage, or moving to a different Fixed rate.

Here are answers to some questions.
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.
No. If you have a valid BER certificate dated before 24 May 2026, it is still valid until expiry. BER certificates expire after 10 years.
Further information on BER certificates can be found on the Sustainable Energy Authority of Ireland (SEAI) website.
