What is the typical BER in Co. Carlow?

Across 8,344 current certificates for Co. Carlow Eircodes, the middle rating is C1. 49% are A or B, 11% E, F or G. Nationally: 51% A/B and 12% E/F/G.

Does a bad BER lower the price?

Yes, and increasingly so: green mortgage rates need B2 or better, 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 a copy of the public SEAI 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 Withdrawn certificates are excluded.
