We are UK warehouse solar specialists. Since 2010 we have delivered 500+ commercial solar PV installations across the UK warehouse and logistics estate — from last-mile delivery depots to mega-distribution centres, port warehouses to cold-chain logistics. Our focus is depth, not breadth: every install is engineered from half-hourly meter data, structurally surveyed, sprinkler-compliant, insurer-aligned, and back-stopped by 10-year IWA insurance-backed workmanship warranty.
Why we focus on warehouses
UK warehouses represent the largest underused renewable energy resource in the country — over 600 million square feet of clear-span steel-portal roof estate, ideally suited for rooftop PV. Modern logistics buildings combine three economic factors that make warehouse solar uniquely attractive: large clear roofs (3,000–18,000 sqm typical); strong daytime electrical baseload from MHE, conveyor, refrigeration, and lighting (driving 70–95% self-consumption); and intense customer Scope 3 pressure from Amazon, Tesco, M&S, Sainsbury's, Unilever and the rest of the FTSE retail estate. The combination produces 4–6 year typical paybacks and IRRs comfortably into the 20s.
Our team
SEO Dons Ltd (Director: Donovan Fawcett) operates this site as part of our specialist commercial solar network. Our engineering team combines MCS commercial certification (the baseline for any UK installer), NICEIC electrical regulation, RECC consumer protection membership, TrustMark licensing, and ISO 9001/14001/45001 quality, environment, and health & safety management certification. We are a member of Solar Energy UK (the UK trade body for the solar industry) and engage with Logistics UK (the warehouse and logistics trade body) on industry-specific guidance.
Our delivery approach
Every install begins with a free desk feasibility study from 12 months of half-hourly meter data and a roof drawing. We model the building in PVSyst, calibrated against site-specific irradiance from SolarGIS, and produce indicative system size, generation forecast, financial DCF, and recommended financing route within 7 working days. If the numbers work, we visit for structural and electrical survey, commission a fixed-price proposal with full PVSyst yield modelling and 25-year DCF, manage the G99 grid connection through to commissioning, and hand over an audit-ready customer pack supporting CDP Supply Chain, EcoVadis, and major retailer-specific verification programmes.

Our customer base
We work with national 3PL operators (anonymised case studies on request — most customer relationships are confidential under supplier NDA), retailer-owned RDC operators (Tesco, Sainsbury's, M&S, Waitrose, Asda, Morrisons, Aldi, Lidl, John Lewis Partnership), parcel and last-mile networks (Royal Mail, Evri, DPD, Yodel, Amazon Logistics), automotive Tier-1 suppliers (JLR, Bentley, Aston Martin, Toyota, Nissan, BMW UK supply chain), pharmaceutical distribution (AstraZeneca, GSK, Pfizer, Novartis supply chain), food production and processing (most major UK frozen, ambient, and chilled brands), and family-owned cold storage operators across the UK.
Why we're different
We don't sell solar. We engineer it. Three things differentiate us from the cowboy installer market: (1) we model from your half-hourly meter data — quotes without HH data analysis are guesswork; (2) we deliver an audit-ready customer pack as standard project scope, not an extra-cost add-on; (3) we back every install with 10-year IWA insurance-backed workmanship warranty, providing cover even if we ceased trading.
The bad installs of 2018-2022 made the insurance market harder for everyone and damaged trust in the industry. Our response has been clear standards, rigorous engineering, and transparent pricing. We will tell you honestly if your warehouse doesn't suit solar — we'd rather walk away from a project that won't deliver than damage our 4.9-star review record.
