Do Solar Panels Increase House Value?
Do Solar Panels Increase House Value? UK 2026 Data
Yes — but the range in the research is wide. Here’s what the studies actually found, why the EPC rating effect matters more than most people realise, and the one situation where solar can complicate your sale.
Yes — owned solar panels reliably increase UK property values. Studies cite uplifts of 1% to 14% depending on method and region. On the UK’s average house price of around £285,000, that’s a potential gain of £2,850 to £40,000. The single strongest driver isn’t the panels themselves — it’s what they do to your EPC rating.
The Studies — and What They Actually Found
The most rigorous piece of research on this topic is a July 2024 Swansea University study that analysed over five million Zoopla property listings against the official Land Registry Price Paid Data. Using machine-learning techniques to control for other variables, the researchers found that solar panels increased property sale prices by 6.1% to 7.1% on average — a meaningful and statistically robust result.
Other studies sit at different points in the range. Conservative estimates from DESNZ-cited research suggest 1–4%. A widely-quoted Rightmove analysis found energy-efficient improvements including solar panels can push values up by up to 14% in strong markets. The honest answer is that the effect depends on your area, your buyer pool, and your EPC rating — but the direction of travel is consistently upward.
What Different Studies Found
Solar Panels & UK Property Value — Research Consensus (2026)
Estimates vary by methodology. All figures reference owned panels only. Sources below.
Note: Higher figures tend to come from studies in high-demand, energy-conscious markets (London, South East). Lower figures reflect UK-wide averages across all property types.

The EPC Effect — Why This Matters More Than the Panels Themselves
Here’s something most articles gloss over: the biggest driver of value isn’t that your house has solar panels — it’s that those panels push your Energy Performance Certificate (EPC) rating up a band. In the UK, the EPC rating is increasingly tied to mortgage eligibility, buyer expectations, and resale price. You can check your current EPC rating for free on GOV.UK.
A solar system typically moves a home from EPC D to C, or C to B. That single jump is significant — research consistently shows that homes rated C or above sell faster and command a measurable premium over otherwise identical D-rated properties. Homes rated A or B are increasingly sought after by buyers conscious of mortgage stress tests and future energy costs.
The government confirmed a major overhaul of the EPC system on 21 January 2026. From October 2026, the single cost-based rating is being replaced with four new headline metrics — energy cost, fabric performance, heating system efficiency and smart readiness — plus a new secondary energy demand metric. Solar paired with a home battery and a smart meter is well placed to score strongly under the new smart readiness metric, on top of the existing cost benefit. See the official DESNZ/MHCLG consultation response on GOV.UK for the full detail. We’ll update this guide once the new-style EPCs go live.
EPC Bands & Where Solar Typically Moves Your Property
Most UK homes are rated D before solar installation. A well-sized solar system commonly moves them to C or B.
What Buyers Actually Think — and the Leased Panel Warning
If your panels were installed under a “rent-a-roof” scheme between 2010 and 2015 (where you got free panels in exchange for the Feed-in Tariff income), the lease transfers with your home. Some mortgage lenders will decline to lend on properties with certain solar lease agreements — which can significantly reduce your buyer pool. If you have leased panels, get legal advice before marketing your home. Owned panels carry none of these complications — and if you’re not sure what paperwork buyers and their solicitors will expect to see, our guides to what MCS certification actually covers and what your solar warranty includes explain exactly what should be in your handover pack.
Owned solar panels are a net positive for UK property values in 2026. The EPC improvement often does as much heavy lifting as the panels themselves. With buyer demand for energy-efficient homes rising and the UK’s energy price cap increasing again by 13% from July 2026, the financial case for buyers to seek out solar homes is stronger than it’s ever been.
