Alpha Solar

Lead times for Greater London renewables installers swing seasonally — late spring and early summer are peak demand. Ask Alpha Solar 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 Alpha Solar should provide the MCS certificate and inverter performance data your supplier will request. Ask Alpha Solar whether they walk customers through the SEG paperwork as part of handover.

Per the public business listing, Alpha Solar list themselves under: Solar PV Installation. Confirm whether they handle other renewable categories before scheduling a survey. Some London-area installers sub-contract specialist work (e.g. roof structural checks, DNO applications), so ask what's done in-house.

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 Alpha Solar 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. Alpha Solar should answer all of these without hesitation.
