DEON Energy

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 DEON Energy which apply before signing.

Yes — three quotes is the UK standard. Use EnergyRanked's London filter to compare DEON Energy against other local installers on rating, review count, and accreditation. Don't just chase the cheapest quote; compare warranty terms and brand specs side-by-side.

Many Greater London-based installers cover a 20–40 mile radius from their base. DEON Energy's exact catchment isn't published on EnergyRanked — ask directly. Distance affects scheduling and travel charges; an installer 90 minutes from your property may quote more for the same work than one 20 minutes away.

DEON Energy typically begins with an initial enquiry via phone or website, followed by a desktop assessment and on-site survey. Ask whether the quote is fixed-price or estimate-only, and confirm what's included (scaffolding, DNO application, commissioning).

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