solar panels for fabrication in Manchester

Why Manchester’s metal trades are moving on solar

Manchester was built on metal, and it kept its engineering backbone long after the cotton mills closed. Greater Manchester still holds one of the densest clusters of sub-contract fabrication, structural steel and precision engineering outside the Black Country, from the sheet-metal and CNC shops on Trafford Park to the jobbing welders and press-brake fabricators across Openshaw, Gorton and Wythenshawe. Their electricity bills have roughly doubled since 2021.

For a fabrication business that is the real story. A shop running fibre lasers, plasma cutters, MIG and TIG sets, a compressor and legally-required weld-fume extraction has watched power overtake almost everything except steel and labour as its biggest controllable cost, and on fixed-price tenders that eats straight into margin. Solar is the one lever that hedges it for 25 years.

Trafford Park, Sharston and the M-postcode workshop estate

Trafford Park is Europe’s largest industrial estate and the single biggest fabrication opportunity in the North West. Behind the food and logistics names sits a deep layer of sheet-metal shops, steel stockholder-fabricators and precision sub-contractors in clear-span portal-frame units, exactly the roofs solar wants. Modern M17 buildings typically offer 2,000 to 8,000 square metres of unobstructed roof, supporting 300kW to 1.5MW arrays.

South of the centre, Wythenshawe Industrial Estate and the neighbouring Roundthorn Industrial Estate host aerospace and engineering supply-chain fabricators near Manchester Airport, while the Sharston Industrial Area mixes heritage engineering sheds with newer units. East of the centre, Openshaw Industrial Estate carries on the metal-bashing tradition of Gorton and Beswick. We cover the full workshop estate, from M17 at Trafford Park and M22 and M23 around Wythenshawe to M11, M12 and M18 through Openshaw and Gorton.

Net zero 2038 and what it means for a fab shop

Manchester City Council declared a climate emergency in 2019 and set a 2038 net zero target, the most ambitious of any major UK city and 12 years ahead of the national 2050 deadline, with the Manchester Climate Change Framework and the GMCA Local Net Zero Hub behind it.

For a fabricator, planning is rarely a barrier. 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 removed in December 2023, so even a large structural-steel shed array usually needs no application. Panels must not project more than 200mm above a sloping roof or 600mm above a flat roof, with conservation areas such as Castlefield and Ancoats the exceptions. The sharper end is procurement: main contractors and public buyers across Greater Manchester now write Scope 2 and responsibly-sourced-steel questions into supplier scorecards, and a fabricator with on-site renewable generation scores better at tender.

Why a Manchester fab roof pays back fast

Because these Trafford Park and Openshaw shops run one daytime shift, Monday to Friday, their heaviest demand falls in the same midday window the array produces most, so 70 to 90 percent of the generation is used on the spot against a 25 to 30p import price rather than leaking back at the 12 to 16p export rate. That on-site match, not roof size, drives the payback here.

A Manchester shop’s demand is spiky on top but steady underneath. The peaks come and go as the plasma table, the fibre laser or a bank of welders fire, but below them runs a load that barely moves: the compressor holding line pressure, the extraction HSE rules force on whenever anyone strikes an arc, the laser chiller, the CNC coolant pumps. That baseload is what the panels feed most efficiently, so we shape every array to a full year of the site’s half-hourly readings, not to its roof area. You can follow that method on the cost page, or run your own figures through the savings calculator. Even under Manchester’s grey skies, a 150kWp array on a typical Trafford Park shed still strips £25,000 to £40,000 a year off the bill.

Electricity North West, G99 and older Manchester roofs

Manchester sits in the Electricity North West DNO area, and any commercial fabrication array is effectively always a G99 connection, since output above roughly 11kW three-phase triggers it. A standard offer takes about 45 working days, a larger array needing a full network study 16 to 24 weeks, so we submit the G99 on day one alongside the roof-load survey rather than adding months at the end.

Two Manchester roof issues come up often. Many older Trafford Park and Openshaw sheds carry asbestos-cement roofs, laid before 2000 and impossible to fix PV to directly, so they need an asbestos survey and over-cladding first, often funded inside the same project. And on heavy structural-steel shops running EOT overhead cranes, the crane-rail and gantry dead loads must come off the roof’s residual capacity before a 15 to 25 kg per square metre array goes on, so a structural engineer signs off every heavy-lifting bay.

We build the array around your process

A sub-contract welding and engineering workshop in Gorton is sized differently from a Trafford Park laser and plasma cutting house with its steady chiller baseload. The detail no generalist checks is the weld-fume extraction: HSE Safety Bulletin STSU1-2019 treats all welding fume as a carcinogen, so LEV is mandatory for indoor welding and its discharge stacks pierce the same roof as the array, which we route the panels around.

A Trafford Park example, worked through

Picture a mid-size sheet-metal and CNC sub-contractor in a clear-span portal-frame unit on Trafford Park, M17, running two press brakes, a fibre laser, a bank of MIG sets and a 45kW rotary-screw compressor across a single day shift, with whole-shop LEV on throughout. Its roughly 1,000 square metre roof takes a 150kWp array generating around 140,000 kWh a year, about 85 percent used on site because the plant runs while the sun is up. At a 27p import rate that self-consumed power, plus a little export, is worth around £33,000 a year, so the system clears its cost in a little under five years and then runs largely for free for the two decades that follow. Swap the estate for Sharston or Openshaw and the arithmetic barely shifts. This is an illustrative model, not a client.

We deliver across Manchester and out into Salford, Trafford, Stockport, Tameside, Oldham, Rochdale and Bury, so a fabricator with units on more than one estate gets consistent design across the lot. Every quote starts with a free feasibility study from your meter data and roof drawings, with an indicative size, generation forecast and payback inside a week. Request a quote and we will tell you honestly whether your site suits solar.
