Properties with an “A” or “B” rating see an average increase of around £57,000 in value, nearly £10,000 more than those with a “C” rating or lower. The difference between “C” or “D” and “E” or “F” is approximately £1,500, while homes with a “G” rating show no extra value.
The impact of upgrading the energy rating on house prices varies significantly by region. The South East experiences the highest increase (£112,821.75), followed by London property investments (£137,613.44), suggesting a higher value placed on energy-efficient properties in these areas.
All regions, except the East of England, South West, and West Midlands, witness a minimum 10% increase in house value for an “A” or “B” EPC rating. However, despite a lower percentage increase, these regions still see a substantial rise (£22,000, £20,000, and £8,000 respectively).
Among the various upgrades, triple and double glazing are the most lucrative, contributing an average increase of £44,770.09 to a property’s value. Effective window insulation is crucial, as single glazing shows no increase in house value, according to Uswitch.
Roof insulation, another key factor in energy efficiency, also significantly enhances property worth, providing an average additional value of £25,152.64. Limited insulation, while contributing positively, has a relatively modest impact at £1,552.14.
