Found a lovely house, good location, layout works for our family, but is has no gas and is heated by old-fashioned storage heaters, so has a very low EPC rating. We currently have full gas central heating in our existing house, rated EPC C. I'm worried about the energy costs. Would it be unreasonable to ask to see some bills? Would storage heaters put you off? I know I could get gas laid on and fit radiators but buying the house would leave us no budget to do this.
