Frequently asked questions

Yes — many UK homeowners can meaningfully reduce electricity bills with solar panels. Savings depend on roof size and orientation, daily usage patterns, your import and export tariffs, and whether you add a battery. Use our savings estimator for an indicative figure tailored to your address.

Yes — panels produce in any daylight, although output is lower in midwinter than summer. You'll generate less per day in December and January, but a well-sized system still meaningfully reduces your annual electricity costs. Our estimator uses your latitude and roof orientation to give a realistic year-round figure.

Most modern solar panels carry a 25–30 year performance warranty. Quality manufacturers guarantee that panels still deliver around 80–90% of their original output at year 25. In practice well-installed panels often keep generating for longer; degradation is gradual.

Most domestic rooftop installs in England and Wales fall under permitted development — no application needed. Exceptions include listed buildings, conservation areas, and certain roof-mounted equipment limits. We'll check your situation as part of the process and tell you clearly if an application is needed.

A typical UK domestic solar system costs around £6,000–£10,000 installed. Final price depends on system size, roof complexity, panel and inverter brand, and whether you add a battery. See our solar panel cost guide for a fuller breakdown.

System cost, your electricity usage, your import and export tariffs, and how much daylight your roof gets all affect payback. Most UK domestic systems pay back in 5–10 years, with 5–7 years being typical for well-sized systems. Adding a battery can shorten or lengthen payback depending on your usage profile.

Yes — new domestic solar installs export to the grid under the Smart Export Guarantee (SEG). You get paid for excess electricity your panels produce, subject to your supplier and meter setup. SEG rates vary between suppliers, so it's worth comparing.

There aren't national grants for solar in the UK right now, but VAT is currently 0% on most domestic installs. Some local schemes or eco-loan products exist regionally and change over time. We'll flag anything that applies to your address when we discuss your project.
