We are a UK commercial solar contractor that specialises in one of the hardest building types to get right: refrigerated and cold storage warehouses. Most solar installers can put panels on a flat roof. Far fewer understand what changes when that roof sits over a chamber held at minus 25 degrees, why the fixing method matters more than the panel brand, and how to design an array that pays back in four years because the refrigeration plant beneath it never switches off. That focus is deliberate. Cold storage has the strongest economics in commercial solar, and it has the least sector-specific expertise on the market.
Why we focus on cold storage
Refrigerated warehousing is the most electricity-intensive part of UK logistics. The compressors, condensers and evaporator fans run 24 hours a day, 365 days a year, which means a cold store consumes nearly everything a rooftop array can produce. Self-consumption above 90% is routine, and that is what drives the four to five year payback that dry warehouses cannot match. But the same buildings carry real complexity. Insulated composite panel roofs cannot be penetrated carelessly without breaching the vapour barrier. Structural loading has to be checked because the roof was built to keep heat out, not to carry ballast. F-gas regulated plant rooms need careful coordination. We built our business around solving exactly these problems, rather than treating a cold store like any other shed.
Our team and track record
Our engineering team covers structural, electrical and refrigeration-aware design. Every project is led by an MCS-certified commercial installer, and we model each system on its own merits using your half-hourly meter data and a PVSyst yield model, not a rule of thumb. We are manufacturer-independent, so we specify the panels, inverters and mounting that suit your roof and your load profile rather than whatever a single supplier wants to move. We have delivered installs ranging from single-chamber facilities to multi-temperature regional distribution hubs, including sites on long institutional leases where landlord engagement and green-lease consent were part of the job.
How we work
Our process is transparent and survey-led. The first proposal is desk-based and free, built from your meter data and roof drawings, delivered within seven working days, with an indicative system size, generation forecast and internal rate of return. If the numbers work, our engineers carry out a one-day structural and electrical survey, after which you get a fixed-price proposal with full yield modelling, a discounted cash-flow analysis and clear contract terms. We obtain insurer pre-design review before fabricating anything, design to LPC sprinkler clearance standards, and calculate wind loading to BS EN 1991-1-4 for your specific site exposure. Installation happens above your operations, so picking, despatch and the cold chain itself keep running. The only outage we need is a few hours for final grid synchronisation, which we schedule for a weekend or a planned shutdown.
What makes us different
The commercial solar market has its share of generalist contractors and outright cowboys, and bad large-roof installs have made insurers nervous about the whole sector. We are the opposite of that. We will tell you honestly if your cold store does not suit solar, and we would rather walk away from a project that will not deliver than damage our record. Insurer sign-off, sprinkler compliance and structural verification are standard on every job, not optional extras. Our workmanship is covered by a 10-year insurance-backed warranty, so the guarantee stands even if circumstances change. We hold the certifications a serious UK commercial installer should hold, every one of which you can verify against the issuing body using the links below.
