Properties in the UK with top-tier energy efficiency ratings are commanding only a marginal price premium over less efficient homes, new data indicates.

Buyers are paying approximately £4,500 more for homes rated 'A' on the Energy Performance Certificate (EPC) scale, a figure that stands in sharp contrast to the thousands of pounds often required to achieve such ratings through retrofitting.

The finding, reported by This Is Money, highlights a persistent disconnect in the UK property market between the upfront capital expenditure for green upgrades and the resulting asset valuation.

While government policy and environmental targets continue to push for higher energy standards, the market's willingness to pay for these improvements remains limited.

The modest premium suggests that buyers are not fully recouping the investment costs associated with insulation, heat pumps, or solar installations.

This dynamic poses challenges for homeowners and investors looking to leverage green credentials for capital appreciation.
