What the EPC tells you
The EPC gives a rating for energy efficiency and environmental impact. It may include estimated energy costs and recommended improvements such as insulation, draughtproofing, heating controls, double glazing or low energy lighting.
Why older homes can score differently
Stone and solid walls
Older solid-wall properties may have more limited or expensive insulation options.
Flats and tenements
Communal ownership can affect whether roof, wall or common-area improvements are practical.
Heating and glazing
Boiler type, controls, window type and draughtproofing can all affect ratings and comfort.
How buyers and sellers should use it
- Buyers should treat EPC recommendations as a starting point, not a final retrofit plan.
- Sellers can make simple improvements, but should be careful with costly works before sale.
- Listed buildings, conservation areas and flats may need permissions or shared agreement.
