EPC rating E: what it means and what it costs
A E is the legal minimum for rented homes, usually meaning little insulation or an old heating system. Across 413,540 homes certified at band E since September 2022, the median modelled heating and hot water cost is £1,593 a year, about £133 a month.
What would a E-rated home your size cost to heat?
The same home at band C: about £710 a year, £790 less.
Scaled from the median modelled cost per square metre of E-rated homes certified since September 2022. These are the standardised running-cost estimates from EPC assessments, and never a prediction of your actual bill, which depends on your tariff and usage.

Loft and cavity insulation plus heating controls are the usual route to D and beyond; grants often apply at this band. The full rundown of measures, costs and sensible order is in how to improve your EPC rating, and if the property is rented, the legal position is in EPC rules for landlords.
