EPC rating F: what it means and what it costs
A F is below the legal minimum for new tenancies: typically solid walls, single glazing, or no central heating. Across 90,292 homes certified at band F since September 2022, the median modelled heating and hot water cost is £2,348 a year, about £196 a month.
What would a F-rated home your size cost to heat?
The same home at band C: about £710 a year, £1,450 less.
