Sunsave

Demand peaks April–August across the UK. Booking in autumn or winter often means shorter waits and sometimes pricing flexibility. Installation itself is a year-round activity in most UK weather — the constraint is scheduling, not the season.

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 Sunsave which apply before signing.

Search 'find-and-update.company-information.service.gov.uk' for the trading name. Look at incorporation date, current status (Active vs Liquidation/Dissolved), most recent accounts filing, and director list. A long-trading limited company with up-to-date accounts is a safer signal than a recently incorporated firm.

Use the phone number and email on the listing page above, or visit their website (sunsave.energy). For initial enquiries, email tends to give you a written paper trail; for an urgent quote, phoning often gets a faster site survey booking.

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 Sunsave for site-specific yield modelling based on your roof orientation, pitch and shading.
