The EPC system is subjective. Craig Powell *, an energy assessor, estimated that one in four EPC ratings was wrong. âTwo guys can do the same property and come up with different numbers,â he said.
Julia Rennie, 59, spent Â£ 4,000 to replace the old night storage heaters in two of her apartments with electric heaters.
Energy bills for its tenants have dropped dramatically. But the EPC assessment did not take into account the fact that they previously had to plug in fan heaters in the evening at peak rates. The EPC scores fell and each apartment had a different result: in one, the EPC fell from C to D, in the second it fell from C to E. âThe apartments are practically identical, it doesn’t doesn’t make sense, âMs. Rennie said.
In September 2020, the government released plans to make EPCs more reliable and is examining the changes needed to get people to improve the energy performance of their homes. But experts are frustrated with the lack of progress so far. “They have done multiple consultations, but nothing has actually been done,” said Ms Ralston.
Mr Powell also warned that government subsidy programs, such as the renewable heat incentive, created opportunities for fraud. He said having a bad EPC rating would benefit installers financially and that he had seen evidence of tampering.
âIt was clear that the EPC they used to claim the grant was deliberately inaccurate,â he said. “There’s a lot of nudge nudge, wink wink, don’t look for certain things.”
A government spokesperson said, âNo property will be made non-mortgage-free by our plans to improve home energy efficiency.
“Our reforms will provide a fairer system for everyone, helping homeowners and homeowners improve the energy performance of their homes, lower their energy bills and increase consumer choice.”
