GreenEnco

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.

An IBG is essential — it covers the workmanship warranty if the installer ceases trading. MCS-certified installers usually offer IBG via the MCS scheme. Confirm GreenEnco provides an IBG certificate at handover; don't accept a workmanship guarantee that's only as good as the installer's continued existence.

GreenEnco's website (greenenco.co.uk) typically lists their service categories, recent case studies, panel and inverter brands they install, and contact details. Cross-check against their Google listing — discrepancies between the two are a useful sanity check.

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

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 GreenEnco which apply before signing.
