FAQ: What do the different BER ratings mean?
Since 2011 every property in Ireland now needs a Building Energy Rating (BER) certificate prior to going on the market for sale or to let. A BER certificate is an assessment and rating of your property’s energy efficiency. Each house is assessed and comes out with a score on a range of A1 to F.
Here is a rough guide to what type of property have which ratings:
- A1 – brand new, highly efficient purpose built house (such as Passive House).
- A2 – as above, still a very high standard to attain.
- A3 – most new urban homes, usually includes solar panels.
- B1 – a modern 10-20 year old property, with additional efficiency improvements.
- B2 – a modern or retrofitted property, depending on the age of the house and extent of improvements.
- B3 – as above, depending on the age of the house and extent of improvements.
- C1 – A common 15-20 year old property with double glazing and attic insulation but no other measures.
- C2 – A well-built rural property with oil-fired heating, insulation and efficient heating.
- C3 – A typical apartment score in an 10-15 year old development.
- D1 – A 20-40 year old house with double glazing, gas boiler and some insulation.
- D2 – As above but with just double glazing, older boiler.
- E – A 30-40+ year old house with no improvements or double glazing.
- F – An older property, barely a shell with single glazed windows and no insulation.
Exempt – Listed historic buildings or derelict properties are exempt.
