EPC rating D explained
EPC D is around the middle of the scale and close to the England & Wales average — not a red flag, but one band below the C level lenders' green products and the proposed 2030 rental standard target. Most D homes can reach C with a handful of measures.
Where band D sits on the A–G scale
Band D (SAP 55–68) is the single most common band in the UK housing stock — huge numbers of solid-wall Victorian and Edwardian homes, and many 20th-century houses, sit here. It is 'average', not 'bad', but it is just below the C threshold that matters for green mortgages and the proposed rental rule.
EPC D and running costs
A D-rated home costs a little more to run than a C and noticeably more than a B. The certificate's own running-cost estimate is the number to trust — it reflects this property's heating, insulation and glazing, not an area average.

- 1Loft insulation top-up to 270mm and cavity-wall insulation where the walls are suitable — usually the cheapest points gained.
- 2A modern condensing boiler or, increasingly, a heat pump, plus room thermostats and heating controls.
- 3Draught-proofing and, where affordable, double or secondary glazing.
- 4Low-energy lighting throughout (a small but easy point-gainer on the SAP score).
Measures and indicative costs vary by property — an EPC's own recommendations page lists what an assessor thinks would raise that exact home's rating.
What band D means for landlords
A rented home at D currently meets the existing MEES minimum (E) but sits below the EPC C standard the government has proposed for privately rented property by 2030. Landlords typically need one or two measures to close the D-to-C gap.
The current Minimum Energy Efficiency Standard requires privately rented homes to be at least EPC E. The government has proposed raising this to EPC C for privately rented homes by 2030; the exact rule and dates are being finalised.
