Do solar panels add value to UK homes? What the data suggests

TL;DR

Buyers value lower running costs and better EPCs; panels can support that.

Uplift varies by area and market cycle—think “market support”, not a guaranteed premium.

Focus on a tidy install, good documentation, and realistic payback.

Why value can increase

Solar reduces electricity purchased from the grid and can improve EPC scores. In competitive markets, efficient, lower‑cost homes are more attractive, which can translate to stronger offers.

What actually drives the uplift

Local demand: some areas prize efficiency upgrades more than others.

Energy pricing: high tariffs make low running costs compelling.

System quality: reputable components, neat install, and a clear handover pack.

Evidence: bills, monitoring screenshots, and inverter/battery warranties.

Setting expectations

Property values move with wider market forces. Treat solar as a comfort, cost‑control and resilience upgrade that can help your listing stand out rather than as a fixed cash add‑on.

Is solar worth it if value is uncertain?

Usually yes—if the design matches your usage. Self‑consumption, time‑of‑use tariffs and (optionally) batteries can shorten payback while giving day‑to‑day savings.

Practical steps to support valuation

Keep manuals, DNO/Part P certificates and MCS documents together.

Label consumer units and isolators; note commissioning settings.

Track generation and self‑consumption to demonstrate real savings.

Bottom line

Solar can support higher perceived value via lower bills and better EPCs, but outcomes vary. Prioritise a quality install and clear documentation to make the benefit obvious to buyers.
