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 we initiate before contract. Physical install on roof: 2–5 days for 100–500 kW, 5–10 days for 1 MW+. We schedule installation around your shutdown windows.

What grants are available for Swindon manufacturers?

Nationally: Industrial Energy Transformation Fund (IETF) Phase 3 covers 30–50% of qualifying decarbonisation costs. Annual Investment Allowance (AIA) covers 100% of capex up to £1m in year 1. Locally, check current South West business support programmes — we map every available route as part of the free feasibility study.

Will I need planning permission in Swindon?

In most cases no — Permitted Development Rights (Class A Part 14, GPDO 2015) cover rooftop PV on industrial buildings under 1 MW. Listed buildings, conservation areas and PV projecting more than 200mm above the roof require full planning. We confirm planning status during the desk feasibility before any quote.

What roof types do you cover 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 fixed-price quote for my Swindon site?

Three steps. (1) Submit a free quote request with your annual electricity spend and roof type. (2) We pull half-hourly meter data and run PVSyst yield modelling. (3) On-site survey and fixed-price proposal within 7–10 working days. No obligation, no hard-sell — we’ll tell you honestly if your site doesn’t suit solar.
