If you’re selling, renting or planning upgrades, you’ll need a BER. Here’s what it costs in Ireland, what changes the price, and how the assessment works.
Short answer
A BER assessment typically costs €150–€350, carried out by an SEAI-registered BER assessor. The certificate is valid for 10 years.
What affects the price
- Home size — more rooms and floors take longer to survey.
- Location — assessor travel affects the quote.
- Property type and access — apartments are often cheaper than large detached homes.
- How much information you can provide — receipts and details of insulation, windows and heating can speed things up.
Prices are set by individual assessors, not SEAI, so it’s worth getting two or three quotes from registered assessors.
What the assessor does
The BER assessor visits your home and records its construction, insulation, windows, ventilation and heating systems. They enter this into SEAI’s methodology, which produces the rating in kWh/m²/year and a band from A1 to G. The certificate is then lodged with SEAI.
When you legally need one
- Selling — a valid BER must be in place and shown in the advertisement.
- Renting — same requirement for the listing.
- New builds — required on completion.
- After SEAI grant works — a post-works BER is usually needed so your improved rating is recorded.
Make the BER work for you
A BER isn’t just a box to tick — it’s a map of where your home loses energy. Use it to prioritise upgrades that lift the rating and cut bills: start with attic and wall insulation, then see how to improve your BER rating.
