Hi there, my father built a 3 bed detached home in Dublin 16 and gas bills are 2 - 3 times the national average and he wants to get some advice on why this is happening. The house was built in 2007/8 with underfloor heating set in concrete downstairs and rads upstairs that are rarely used. We are looking for some advice on why this may be happening. He has contacted energy provider who just says that he is being billed as per the meter. Appreciate any advice on who can help with this, I have contacted a few companies but has no response. Thanks,
