Has your commercial BER improved after the new methodology changes?
BERready reads your existing non-domestic BER certificate and estimates the rating you'll receive under the new May 2026 methodology — with a confidence score so you know how reliable the estimate is.
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 we can't reliably estimate are marked and shown for free with a caveat.
- • Unlock your high confidence estimate (for BERs completed after Nov 2018) for €20 per BER.
- • Each unlocked BER report shows the projected new rating (A0, A, B, C, D, E, F or G).
- • 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.
