Has your commercial BER improved under new criteria?
BERready - designed by trained BER assessors - reads your existing BER certificates to project the revised BER ratings your commercial properties are likely to achieve under the May 2026 BER assessment changes. Understanding where each property now stands is the first step towards improving rentability, maximising rental value, and creating a clear roadmap to achieving A and B ratings.
What changed in May 2026?
The Sustainable Energy Authority of Ireland (SEAI) updated the methodology used to calculate the Building Energy Rating for non-domestic buildings in Ireland. The new scale has removed numbering from letter grades i.e. A2 is now A. However, the methodology in determining BER ratings has also changed - so a cert issued before May 2026 does not automatically reflect the building's new rating. For example, a B2 building could now be an A, B or C grade depending on the building activity/use, geometry, and other factors.
BERready re-runs the numbers on your existing cert so you know where you stand before you commission a fresh assessment (which can cost between €250 - €5,000+ per cert).
- • Uploads and validity checks are free.
- • Certs marked Estimated are shown for free with a caveat.
- • Unlock your Comprehensive result for BERs completed after November 2018.
- • Each unlocked BER report shows the projected new rating (A0, A, B, C, D, E, F or G).
- • If a certified assessment under the new methodology comes back worse than what we predicted, you get your money back.
- • No subscription or recurring fees - pay only for the certs you choose to unlock.
- • Non-domestic BERs only - domestic certs will be flagged as invalid.
Why check my current BER?
Commercial BERs are becoming increasingly important in determining a property's value, marketability, and letting potential. Understanding what your building's BER could achieve under the new methodology can help you decide whether renewing your BER certificate is worthwhile. A higher rating may enhance your property's value, support stronger rental values on new lettings, and reveal whether achieving an A rating is now more attainable - or more challenging - than previously expected.
