Swindon factory solar — expanded FAQ
How long does a Swindon factory solar install take?
From contract signature to commissioned system: 8–14 weeks for systems up to 500 kW, 12–16 weeks for 1 MW+. The longest item is the G99 grid connection (6–18 months DNO timeline) which your installer should initiate before contract. Physical install on roof: 2–5 days for 100–500 kW, 5–10 days for 1 MW+. Installers typically schedule the work around your shutdown windows.
What grants are available for Swindon manufacturers?
Nationally: the Industrial Energy Transformation Fund closed in July 2025 with no successor fund planned, so the Annual Investment Allowance (AIA) — 100% of capex up to £1m in year 1 — is the main relief. Locally, ask your local growth hub or combined authority about current regional business support.
Will I need planning permission in Swindon?
In England, rooftop solar PV on non-domestic buildings is usually permitted development (Part 14, Class J of the GPDO) up to 1 MW, subject to conditions; Scotland, Wales and Northern Ireland have their own rules. Listed buildings, conservation areas and PV projecting more than 200mm above the roof need full planning. Your installer should confirm planning status before quoting.
What roof types suit factory solar in Swindon?
All commercial roof types: standing seam metal (clamp-fix, no penetrations), profiled / corrugated metal (rail-mount), flat membrane (ballasted), single-ply EPDM (mechanically fixed). Asbestos-cement roofs cannot be retrofitted — refurbishment to a modern membrane is required first. See our roof weight load guide for structural requirements per roof type.
How do I get a quote for my Swindon site?
Three steps. (1) Submit a quote request with your annual electricity spend and roof type. (2) We pass your enquiry to a matched installer. (3) The installer can then model your half-hourly meter data and roof, survey the site and send a proposal. A quote request carries no obligation.
