In Ireland, the landlord is generally responsible for arranging and paying for a property's BER assessment and certificate before advertising it for rent. A tenant would not normally be expected to pay this cost separately, although rental prices may reflect the property's overall running and maintenance costs. The assessment fee varies by property size, type and assessor, so landlords should request quotes from an SEAI-registered BER assessor. You can check the property's BER rating and certificate details on the official SEAI register.
