How much do solar panels cost in London in 2026?
One of the first questions we get from homeowners across West London — whether in Ealing, Acton, Southall, or Hanwell — is simply: what will this cost me?
While every property is different, this guide breaks down the main factors that affect solar panel pricing in London, so you know what to expect before booking a free survey.
Main factors that affect cost
1. System size Larger systems generating more electricity naturally cost more upfront, but also produce greater long-term savings. Your household’s typical energy usage helps determine the right size.
2. Roof type and access Roofs that are straightforward to access with standard scaffolding cost less to install on than complex or hard-to-reach roofs.
3. Battery storage Adding a battery lets you store excess solar generation for use in the evening rather than exporting it back to the grid. This adds to upfront cost but typically improves overall savings over time.
4. EV charger add-ons Many London homeowners are now combining solar installation with an EV charger, since generated electricity can be used to charge a car during the day.
Are there any government incentives in 2026?
Incentive schemes and VAT treatment for solar installations can change, so it’s worth checking current guidance directly with an installer or via GOV.UK rather than relying on outdated figures — we can talk you through what currently applies at the time of your quote.
How long until solar pays for itself?
Payback periods depend on your system size, energy usage patterns, and how much of the generated electricity you use directly versus export. A tailored quote will include a realistic savings estimate based on your actual property and usage.
Why get a local quote rather than an online calculator?
Generic online calculators can’t account for your specific roof pitch, shading from nearby buildings or trees, or local planning considerations — all of which affect real-world cost and output. A site visit from a local installer gives a far more accurate picture.
