solar panels for fabrication in Stoke-on-Trent

Why Stoke-on-Trent’s metalworking base is turning to solar

Stoke-on-Trent is best known for pottery, but the same kilns and heavy industry that gave the Potteries their name built a deep metalworking economy alongside the ceramics. Colliery gear, kiln plant and mining machinery all needed fabricators, foundries and toolmakers, and that metal-bashing heritage never left the six towns. Today the ST postcodes hold a substantial cluster of sub-contract fabrication, structural-steel, sheet-metal and precision-engineering firms supplying the ceramics, construction, automotive and rail work that still runs through Staffordshire, and these shops have watched their electricity bills roughly double since 2021.

For a fabrication business that bill is the whole story: power is now the biggest controllable cost after steel and labour, and on fixed-price tendered work that rise comes straight off an already thin margin. Solar hedges it for 25 years, and it suits the way a Potteries fab shop runs: a Longton weld bay fires its arcs between clocking-on and knocking-off on a weekday, so the roof generates hardest at the hours the meter spins fastest and nearly all of that midday output is used on site at the full 25 to 30p import price rather than spilled to export at 12 to 16p.

Etruria Valley, Trentham Lakes and the ST-postcode workshop estates

The city’s modern industrial spine runs through a handful of well-defined estates. Etruria Valley Enterprise Zone, reclaimed from the old steelworks and canal-side works, is Stoke’s flagship business park, its clear-span portal-frame units offering 1,500 to 6,000 square metres of unobstructed steel-deck roof that support 200kW to 1MW arrays. Trentham Lakes to the south carries a similar mix of light-industrial sheds where sub-contract engineers and metal finishers work. Festival Park, on the former Shelton Bar steelworks site north-west of Hanley, blends retail with working units, while Park Hall to the east and the older stock around Wolstanton Retail Park carry the heavier metal trades.

We deliver across the full ST-postcode estate, from ST1 and ST4 through Hanley and Stoke itself, ST3 around Longton and Park Hall, ST5 into Newcastle-under-Lyme and ST6 across Burslem and Tunstall, out to ST7, ST8, ST10 and ST11 in Kidsgrove, Biddulph and Cheadle, working districts where a fabrication roof does nothing but weather when it could be cutting the bill beneath it.

Stoke-on-Trent City Council, net zero and what it means for a fab shop

Stoke-on-Trent City Council declared a climate emergency and set a 2050 net zero target, delivered through its Stoke-on-Trent Climate Change Action Plan, with the heritage ceramics industry making industrial decarbonisation a live local issue. Planning is rarely a barrier for a fab shop: rooftop PV on an industrial unit is normally Permitted Development under Class A Part 14 of the GPDO 2015, and the old 1MW cap was lifted in December 2023, so even a large array on an Etruria Valley or Trentham Lakes shed usually needs no application, provided panels stay within 200mm of a sloping roof or 600mm of a flat roof. The exceptions are the city’s listed and conservation areas, such as the historic bottle-kiln sites and parts of Burslem, not a standard trading-estate unit.

Etruria Valley’s Enterprise Zone status is worth checking, since enhanced first-year allowances only apply inside a designated special tax site, but for most Stoke fabricators the relief that does the heavy lifting is the Annual Investment Allowance, giving 100% year-one tax relief on the first £1m of qualifying spend. Solar counts as special-rate plant, so it does not qualify for full expensing, and these figures are illustrative, so confirm your position with an accountant or HMRC. Procurement is the sharp end too: buyers now write Scope 2 and responsibly-sourced-steel questions into their scorecards, so an on-site renewable line item scores a Stoke fabricator better at tender.

National Grid Electricity Distribution, G99 and the local grid picture

Stoke-on-Trent sits in the National Grid Electricity Distribution area, formerly Western Power Distribution. Any commercial fabrication array is effectively always a G99 connection, since inverter output above roughly 11kW three-phase triggers it, and a larger array needing a full network study can run 16 to 24 weeks to a formal offer, so we submit the G99 application on day one and the connection clock starts before the panels are ordered.

Two Stoke-specific roof issues recur. Much of the older stock around Burslem, Longton and the pre-regeneration Etruria and Shelton sites carries asbestos-cement roofs, which cannot take rooftop PV directly and usually need over-cladding or re-roofing first, often funded inside the same project. And on heavier structural-steel shops running EOT overhead cranes, the crane-rail and gantry dead loads must be deducted from the roof’s residual capacity before a 15 to 25 kg per square metre array is added, so a structural engineer signs off every heavy-lifting bay.

From welding shop to structural steel, we build around your process

The design follows the load. A sub-contract welding and engineering workshop in Longton with spiky MIG and TIG loads is sized differently from a Trentham Lakes laser and plasma cutting house whose chillers and assist-gas compressors give a large steady baseload, which is why we size every Stoke array from your half-hourly meter file, not your bare roof area. The detail no generalist checks is weld-fume extraction: HSE Safety Bulletin STSU1-2019 treats all welding fume as a carcinogen, so LEV is mandatory for all indoor welding and its ductwork shares the roof with the array, so we route the panels, cabling and walkways around those penetrations.

We deliver across Stoke-on-Trent and out into Newcastle-under-Lyme, Stafford, Crewe, Leek and Cheadle, so a fabricator with units on more than one North Staffordshire estate gets consistent design and reporting.

What this looks like on an Etruria Valley unit

Picture a sub-contract sheet-metal shop in a clear-span portal-frame unit on Etruria Valley, welding steel for the construction-steel supply chain. It runs a 37kW rotary-screw compressor, a bank of MIG sets, a single fibre laser and mandatory LEV extraction on one weekday day shift, and its roughly 3,000 square metres of steel-deck roof easily carries a 150kWp array. That system generates around 140,000 kWh a year, roughly 85 percent of it used on the shop floor because load and generation both peak in the middle of a working weekday, worth close to £33,000 a year off a doubled bill for a payback inside the four-to-five-year window the sector sees here. It is illustrative, not a named client, but it is the shape of return we model for real Stoke fabrication roofs from a genuine meter file.
