EPC rating C: what it means and what it costs
A C is the band the government wants rented homes to reach, and where a well-insulated older home with efficient heating lands. Across 3,086,831 homes certified at band C since September 2022, the median modelled heating and hot water cost is £636 a year, about £53 a month.
