00:01A construction firm has warned households in England and Wales about energy costs as
00:06cold weather continues following Storm Goretti. Analysis of EPC data suggests more than half
00:12of homes are rated D to G, meaning poorer efficiency and higher bills. The firm says
00:18a typical three-bedroom semi with an A rating could cost hundreds of pounds a year to heat,
00:23while a similar G-rated home may cost thousands. In Yorkshire and the Humber, Richmondshire has the
00:30highest share of lowest rated properties. Experts say insulation and glazing upgrades can help,
00:36but ventilation must be maintained. The figures are estimates based on certificates and not
00:41individual usage.
