Frequently asked questions
What UK grants or schemes apply to a solar install with Radius 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 Radius Energy which apply before signing.
How does Radius Energy's quote process work?
Radius 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).
When is the best time to book a solar install with Radius Energy?
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.
Is solar still worth it in Belfast given the climate?
Belfast 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 Radius Energy for site-specific yield modelling based on your roof orientation, pitch and shading.
What renewable services does Radius Energy offer in Belfast?
Per the public business listing, Radius Energy list themselves under: Solar panel installation. Confirm whether they handle other renewable categories before scheduling a survey. Some Belfast-area installers sub-contract specialist work (e.g. roof structural checks, DNO applications), so ask what's done in-house.
