Energy-Tech

Lead times for Greater London renewables installers swing seasonally — late spring and early summer are peak demand. Ask Energy-Tech directly for current scheduling once you've got a written quote. Plan for 4–12 weeks from deposit to install on a typical residential project; complex roofs or DNO upgrades can extend that.

SEG registration is usually handled by your electricity supplier rather than your installer, but Energy-Tech should provide the MCS certificate and inverter performance data your supplier will request. Ask Energy-Tech whether they walk customers through the SEG paperwork as part of handover.

Yes — three quotes is the UK standard for solar PV. Use Energy-Tech'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.

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 Energy-Tech which apply before signing.

Key questions: panel and inverter brands (and warranties for each); installer MCS number; expected install lead-time; deposit terms and refund policy if cancelled before survey; who handles the DNO application; and roof/structural inspection responsibility. Energy-Tech should answer all of these without hesitation.
