Frequently asked questions
What warranty does Thunder Energy Services typically offer?
UK solar workmanship warranties commonly run 5–10 years; panel performance warranties 25 years; inverter warranties 5–12 years. Ask Thunder Energy Services specifically what's covered, who underwrites it, and what happens if they go out of business (an MCS Insurance Backed Guarantee — IBG — covers this scenario).
Is solar still worth it in London given the climate?
London gets enough annual sunlight for a typical 4 kW domestic system to produce roughly 3,200–3,800 kWh/year. Payback periods are typically 8–11 years at current electricity prices. Ask Thunder Energy Services for site-specific yield modelling based on your roof orientation, pitch and shading.
What UK grants or schemes apply to a solar install with Thunder Energy Services?
Current UK support includes 0% VAT on residential solar PV and battery installs (HMRC zero-rating until at least 2027), the Smart Export Guarantee paying for exported electricity, and — for heat pumps — the Boiler Upgrade Scheme (England/Wales) or Home Energy Scotland Grant + Loan (Scotland). Eligibility depends on the property and the install. Confirm with Thunder Energy Services which apply before signing.
Should I get multiple quotes alongside Thunder Energy Services?
Yes — three quotes is the UK standard for solar PV. Use Thunder Energy Services's quote as one of those three. Compare not just price but warranty terms, MCS certification, and panel/inverter brands. Specs vary widely between installers.
Does Thunder Energy Services offer free site surveys before quoting?
Most reputable UK installers — including most London-area firms — offer a free desktop survey followed by a paid or no-cost roof inspection. Thunder Energy Services's specific policy isn't published on EnergyRanked; ask when you make initial contact (their website thunderenergy.co.uk is a useful starting point). A red flag would be any installer quoting without ever physically seeing the roof or property.
