Commercial solar across County Durham

County Durham is where we live, where the company is registered and where most of our work sits. The base is at St Helen Auckland on the edge of Bishop Auckland; the registered office is in Spennymoor; the landline is a 01388 number. When we say Durham comes first, it is a statement of geography, not marketing.

It is also, quietly, one of the better counties in England to own a commercial roof. Over half a million people live here — 522,100 at the last census, making it the largest local-authority area in the North East — and they are served by a working economy that still makes, stores and moves physical things. The buildings that economy runs on are overwhelmingly the kind solar was made for: wide-span portal-frame sheds with sheet-metal roofs, on estates that were laid out for industry and never stopped being used for it.

Start with the scale of the estate network. Aycliffe Business Park at Newton Aycliffe covers around 700 hectares, holds more than 500 businesses and employs roughly 10,000 people — the biggest single employment area in the county, and now reckoned the biggest business park in the North East. At Bowburn, just off junction 61 of the A1(M), the 205-acre Integra 61 scheme is bringing forward up to three million square feet of industrial and logistics space, with Amazon already on site. On the coast near Seaham, the £120 million Jade Business Park at Murton has capacity for up to a million square feet, with Sumitomo Electric Wiring Systems its first tenant. And at Sedgefield, NETPark — the county’s £85 million science and technology park, home to two national Catapult centres — is a measure of where the county thinks its economy is going: the park’s third phase is being designed with no connection to the gas network at all, with a solar farm under consideration alongside it.

Every one of those sites is a concentration of exactly the roof type we prefer to work on. A trapezoidal or standing-seam steel roof takes a clamp-mounted array without wet trades and, on many profiles, without a single penetration. The yield this far north is honest rather than heroic — plan on the 800–950 kWh per installed kWp band for a well-oriented roof, and the bottom of it for shallow-pitch sheds — but a business that uses its power in the daytime keeps far more of the value of each unit than any export tariff pays.

Then there is the other County Durham: the farmed west. Beyond Crook and Willington the county climbs into Weardale, and from Wolsingham up the dale the holdings are livestock farms with steel-framed sheds, strong daytime loads where dairying and refrigeration persist, and long distances from the nearest substation — all of which makes a properly designed roof array more useful there, not less. Agricultural buildings are a core part of what we do, not a sideline, and the same is true across the county’s arable east towards Sedgefield and Ferryhill.

The council’s direction of travel helps the case. Durham County Council declared a climate emergency and now works to twin targets: net-zero for its own operations by 2030, and net-zero for the county as a whole by 2045, with its third Climate Emergency Response Plan running 2024–2027. It has already cut its own emissions by 64% since 2008/09 — this is a council that treats decarbonisation as delivery, not decoration, and county businesses generating their own power are pushing in the same direction it is.

One more thing we bring to a County Durham job that a visiting installer cannot: thirty years of electrical contracting in this county. If the survey turns up a distribution board that will not take an inverter, or a fixed-wire test that is overdue before anything new is connected, the same firm handles it — one contractor, one accountable name.
