Solar and Property Values: 2026 Data

How much do solar panels add to property value?

Do solar panels increase UK property value? The peer-reviewed evidence says homes with solar sell for more — but by a range, not a number. UK research has found that homes with solar panels sell for more than comparable homes without them. A 2024 study of around 5 million Zoopla observations (Asproudis et al., Energy Economics) estimated a selling-price premium of 6.1% to 7.1% using causal machine learning, and 3.5% on its lowest estimate using matching methods — so the size of the effect depends heavily on the method. That is an average association across the whole market, not a valuation of any particular home. It is not a guaranteed uplift, and we cannot tell you what solar would add to your property. WHY THE RANGE MATTERS: 6.1-7.1% comes from the study's causal machine-learning models; 3.5% is its own lowest estimate, using matching. The published abstract also records a DECLINING trend in the premium over time, while finding that it persists. EPC IMPROVEMENT: solar typically improves an EPC rating by 1-2 bands (e.g. D→C or C→B), which is what many buyers and lenders look at first. WHAT WE REMOVED FROM THIS PAGE: figures previously attributed to BEIS (1-3% per EPC band), a £300,000 worked example, a £5,000-£10,000 'mid-point estimate', an estate-agent survey statistic (78% in 2026, up from 45% in 2019) and a Rightmove search-volume statistic (23% more searches). None could be verified against the named source, so none are published here. WHAT WE WILL NOT DO: convert a national percentage into a pound figure for your home. The study's own £14,062-£16,368 range is tied to its sample average sale price of £230,536 and does not transfer to a different house.
