John completed the BER assessment for our house in Dromahair. He was very thorough and explained what was assessed and what our options were regarding improving the energy efficiency. I would highly recommend his services.
Olaf Springer
SLIGO
John did a BER review of our house near Sligo, which we needed after we got our solar panels installed. John was very helpful not just in explaining the detailed report, but also took time to explain what other improvements would be beneficial for us and which were not. Overall a very professional and enjoyable experience – we learnt quite a lot!
