How long is a BER certificate valid for?

A BER certificate is valid for up to 10 years, unless you make changes to the home that would materially affect its energy performance.

Do I need a BER to get an SEAI grant?

For most individual grants you do not need a BER beforehand, but a pre- and post-works BER is required for one-stop-shop deep retrofit support. A BER is always the best way to decide which upgrades are worth doing.

Who can carry out a BER assessment?

Only a BER assessor registered with the SEAI can issue a valid BER certificate. Always check the assessor is on the SEAI's published register.

What is a BER?

A Building Energy Rating (BER) is an energy label for your home, from A1 (most efficient) to G. You need a valid BER to sell or rent a property, and it is the starting point for planning an SEAI-grant-funded upgrade.
