Questions people ask
- What is the typical BER in Co. Cork?
- Across 77,408 current certificates for Co. Cork Eircodes, the middle rating is B3. 54% are A or B, 14% E, F or G. Nationally: 50% A/B and 12% E/F/G.
- Does a bad BER lower the price?
- Yes, and increasingly so: green mortgage rates are tied to the BER (each lender sets its own band; AIB asks for A0, A or B on a certificate dated after 24 May 2026), and buyers now price the retrofit in. On the other side, a D or E house with a good advisory report is a negotiating tool: the seller cannot dispute what their own assessor wrote.
- How were these figures compiled?
- From certificates published on the SEAI National BER Register, grouped by the Eircode routing key (the first three characters), with each routing key assigned to the county where most of its sales fall. Withdrawn certificates are excluded.
