What Solar Actually Costs in the UK
The Energy Saving Trust puts the average home solar system at 4.5kWp, costing around £6,100 to install. That is roughly 12 panels on 20 to 30 square metres of roof.
Installation currently carries 0% VAT until 31 March 2027, after which it reverts to the reduced 5% rate. A well-oriented UK roof generates roughly 800 to 900 kWh per kWp each year, so a 4.5kWp system produces in the region of 3,600 to 4,000 kWh annually.

Standards You Can Check
MCS-Certified Installers Only
MCS is not a legal licence, but without an MCS-certified installation you will struggle to get Smart Export Guarantee payments, and grant schemes require it. Every installer we work with is MCS-certified (mcscertified.com).
Consumer Code Protection
MCS installers must belong to a consumer code such as RECC (recc.org.uk) or HIES, which set standards for sales practice, deposits and dispute resolution.

Realistic Payback, Stated Plainly
With current prices and export payments, payback on a typical UK system is 9 to 12 years (Energy Saving Trust, July 2026). We say that plainly rather than promising your bills will vanish.
Frequently Asked Questions
A typical home solar system costs around £6,100 to install, based on the Energy Saving Trust's reference 4.5kWp system (July 2026). That is roughly 12 panels covering 20 to 30 square metres of roof. Installation currently carries 0% VAT until 31 March 2027. Actual prices vary by roof, specification and installer, which is why comparing several quotes matters.
No, there is no universal UK solar grant. What exists instead: 0% VAT on installation until 31 March 2027, ECO4 support for low-income and fuel-poor households (runs until 31 December 2026), and the Warm Homes Plan launched in January 2026, which includes fully funded solar for low-income homes and low-interest loans for other homeowners. In Scotland, Home Energy Scotland no longer funds standalone solar PV. For most homeowners the real financial support is the VAT relief plus Smart Export Guarantee payments.
The Smart Export Guarantee (SEG) is the scheme that pays you for electricity you export to the grid. Suppliers with at least 150,000 domestic customers must offer a tariff, rates are set by each supplier and must be above zero. As of July 2026, Octopus pays 12p/kWh on its flat Outgoing tariff and British Gas pays up to 12p/kWh for its own customers. You will need an MCS certificate and a smart meter to sign up. Rates change often, so check supplier pages before you commit.
Realistically 9 to 12 years for a typical UK system, with export payments included. The Energy Saving Trust's July 2026 figures put payback at around 9 years in London, 10 to 11 years in Manchester and 11 to 12 years in Stirling. Panels keep generating well beyond that, so the years after payback are where the return builds.
You don't legally need MCS to have panels installed, but without an MCS-certified installation you will struggle to get SEG export payments, and grant schemes require it. In practice, always use an MCS-certified installer. Every installer RenewQuote works with is MCS-certified.
Roughly 800 to 900 kWh per kWp per year for a well-oriented UK roof, based on the MCS estimation method used by installers. Output is higher in southern England and lower in northern Scotland. For the typical 4.5kWp system, that works out at roughly 3,600 to 4,000 kWh per year. Your installer must give you a site-specific estimate using the MCS methodology before you sign.
