Do Solar Panels Add Value to Your House? UK 2026
Owned solar panels can add around 2–4% in 2026, as buyers increasingly price in lower running costs and a better EPC. But the detail matters — leased or rented systems can complicate a sale rather than help it. Here’s the honest breakdown.

When Solar Adds Value — and When It Doesn’t
The single biggest factor is ownership. Owned, paid-off panels are a clean asset that lowers bills and lifts the EPC. Leased or rent-a-roof systems tie the roof to a third-party agreement that buyers’ solicitors and lenders scrutinise, which can slow or complicate a sale.
| System type | Effect on value |
|---|---|
| Owned outright, in-warranty | Adds ~2–4%; lower bills + better EPC |
| Owned with battery storage | Can add more; stronger self-use story |
| Leased / rent-a-roof | Neutral to negative; extra legal checks |
| Old, out-of-warranty panels | Limited; buyers weigh replacement risk |
Solar is one of several energy improvements: compare it in best-ROI home improvements.
Buyers Are Pricing In Running Costs
Bills matter more
With energy costs front of mind, buyers value a home that runs cheaply. Owned solar is a visible, tangible saving they can factor into an offer.
EPC is a selling point
Solar can lift the EPC by a band, which increasingly features in listings and reassures cost-conscious buyers and lenders.
Battery adds a story
Panels with storage let a buyer use more of what they generate, strengthening the self-sufficiency appeal that adds value.
