BER Map
This colour coded map of Ireland allows you to zoom into small geographical areas of Ireland and explore Building Energy Rating (BER) information for clusters of homes.
About the map
Upcoming Update - In line with the Energy Performance of Buildings Directive, a new simplified BER scale for Irish homes will be introduced on 24th May 2026. Further details are available here. To ensure consistent visualisation of both new and existing BER records, the colour coding of the SEAI BER Map will soon be updated to align with the new scale.
This colour coded map of Ireland allows you to zoom into small geographical areas and explore Building Energy Rating (BER) information for clusters of homes. It also highlights the spatial distribution of all BER ratings across the country.
The data was originally collected by BER Assessors when they completed a BER assessment using the Dwelling Energy Assessment Procedure (DEAP) software.
Please note the BER Map is representative of only a proportion of the total Irish residential dwelling stock however the map is updated on a monthly basis with the latest published assessments.
How it works
Interactive tools within the map will allow users to view BER statistics and breakdowns for each small area, filter areas of the map based on specific BER ratings, and extract underlying data for defined regions.
To ensure consistent visualisation of BER records, the colour coding of the SEAI BER Map will be updated to align with the new simplified BER scale (introduced 24 May 2026). New BER records created after this date will be based on the simplified BER scale only. Existing BER records remain valid for 10 years from their date of issue unless a major renovation has taken place. To facilitate the consistent mapping of BER data, SEAI appends existing BER records with a calculated estimate of their rating under the new simplified BER scale.

Please note that the information supplied is not representative of the entire residential dwelling stock in Ireland. The map only contains approximately 56% of all Irish residential dwellings and as a result some small areas are represented using a low number of dwellings. In addition, the process of spatial disaggregation comes with a slight error rate which has resulted in a small number of dwellings placed under an incorrect Small Area. SEAI accepts no liability to any third party for any loss or damage arising from any interpretation or use of the information contained in this map, or reliance on any views expressed therein.
