Quick Answer
How much does commercial solar cost in Manchester and what's the payback?
Commercial solar in Manchester costs £750–£1,050 per kWp installed (2026). A 100kWp system costs £75,000–£105,000 and generates approximately 87,000–90,000 kWh/year at Manchester's irradiance level (~900 kWh/kWp). At 30p/kWh electricity with 70% self-consumption, annual savings are £18,000–£24,000, giving a payback of 3.5–5 years. With AIA tax relief (25% CT rate reducing net cost by £18,750–£26,250), effective payback falls to 2.5–4 years. Electricity North West (ENW) G99 applications typically take 65 working days.

Commercial Solar Contractors in Greater Manchester
Greater Manchester is the second-largest commercial property market in the UK with over 38 million sq ft of industrial and office space across its 10 metropolitan boroughs. Trafford Park — Europe's largest industrial estate at 1,200 acres — alone consumes more commercial electricity than many mid-sized cities. At current North West electricity rates of 28–30p/kWh, commercial solar offers Manchester businesses a compelling 3.5–5 year payback on unsubsidised installations, reducing to 2.5–4 years after Annual Investment Allowance tax relief.
We are MCS certified commercial solar contractors covering all 10 Greater Manchester boroughs and all M, BL, OL, SK, WA and WN postcodes. Our North West team manages Electricity North West (ENW) G99 applications from pre-feasibility through to commissioning.
Commercial Solar Cost in Manchester: 2026 Pricing Guide
Manchester commercial solar costs are comparable to national benchmarks — the city's mature installer network and good transport infrastructure keep mobilisation costs in line with southern England despite the latitude penalty on generation yield.

Electricity North West (ENW) G99 Connection — Manchester Guide
All commercial solar installations with grid export in Greater Manchester are connected to the Electricity North West (ENW) distribution network. Any system above 3.68kW AC single-phase or 11.04kW three-phase with export requires G99 notification or application to ENW.
ENW G99 process for Manchester commercial solar:
- Pre-application feasibility: We submit a pre-application query to ENW before the project quote stage — particularly important for Trafford Park, Salford Quays and Airport City where network capacity is constrained in some zones
- Standard G99 application: Full application submitted on project sign-off. ENW standard processing time is 65 working days (~13 weeks)
- Grid reinforcement: ENW may require a network reinforcement contribution for large systems (typically 250kWp+) in constrained areas — M17 (Trafford Park), M50 (Salford Quays) and M90 (Airport City) have had some capacity constraints in recent years
- Zero-export option: For sites that cannot wait for G99 approval or where network capacity is limited, a zero-export (self-consumption only) system can be commissioned immediately using an export limitation device. We assess this on every Greater Manchester project
Major Manchester Commercial Solar Zones
Trafford Park (M17, M16)
Trafford Park is the UK's largest urban industrial estate with 1,200 acres of manufacturing, logistics and distribution. Industrial electricity consumption in M17 is extremely high — warehouses, cold stores, and manufacturing plants running continuous day/night loads make self-consumption ratios of 80–90% common. This makes Trafford Park one of the best commercial solar locations in the North West. A 250kWp system on a typical Trafford Park warehouse (10,000m²) generates ~225,000 kWh/year and saves approximately £54,000–£67,500 annually. ENW network capacity in parts of M17 should be pre-checked — particularly for systems above 250kWp with export.
MediaCity UK (M50, Salford Quays)
MediaCity UK at Salford Quays is home to the BBC, ITV, dock10 Studios, and hundreds of creative and tech businesses. Office and studio buildings here have good flat roof access and daytime electricity loads well-matched to solar generation. Typical 50–150kWp systems on MediaCity office buildings achieve 65–75% self-consumption. The M50 postcode has good ENW grid capacity for standard commercial systems. Pre-application checks are still recommended for systems above 150kWp with export.
Spinningfields & Manchester City Centre (M3, M2, M60)
Manchester city centre office stock is increasingly targeted for solar — both rooftop PV and integrated solar glazing. Spinningfields (M3), NOMA (M4), and the Oxford Road corridor offer substantial commercial office stock, much of it with flat roof access suitable for ballasted solar arrays. City centre planning is more complex — Manchester City Council's conservation area designations affect some roof types, and M60 ring road commercial property (particularly Salford side) requires ENW approval. We carry out pre-application rooftop assessments for all city centre projects.
Airport City (M90) & Wythenshawe
Manchester Airport's logistics and commercial zone (M90) is one of the fastest-growing commercial property markets in the North. Cargo sheds, logistics hubs, hotel conference centres and office parks all benefit from commercial solar. The M90 postcode has good solar yield due to more open terrain than city centre, and logistics/warehousing loads offer high self-consumption. The M23 (Wythenshawe) industrial and retail area is similarly well-suited.
Altrincham, Sale & South Manchester (WA14, M33)
South Manchester's commercial property mix — retail parks, GP surgeries, care homes, industrial units and offices — is well-served by 30–100kWp rooftop systems. The M33 (Sale), WA14 (Altrincham) and SK8 (Cheadle) postcodes are popular for commercial solar and typically have available ENW grid capacity for standard export applications.

Manchester Commercial Solar by Business Sector
Manufacturing & Industrial
Manchester's industrial heritage survives in its manufacturing base — chemicals, engineering, food and drink processing, and advanced manufacturing all cluster across Trafford, Bury, Bolton and Oldham. Manufacturing plants with large flat roofs, three-phase supply and high daytime load are ideal for commercial solar. A 200kWp system on a Bolton food processing unit (3,200 impr/month, 28p/kWh) saves approximately £44,800/year. At 25% CT rate with AIA, payback on the net cost (£112,500 after tax relief) is 2.5 years.
Logistics & Distribution
Greater Manchester is the North's largest logistics hub — the M60 orbital, M62 Trans-Pennine corridor, and proximity to Manchester Airport make Trafford Park, Salford, Wigan and Warrington key distribution locations for national operators. Distribution centres (DC) with 10,000–50,000m² floor areas often support 500kWp–2MWp of roof-mounted solar, with weekend/night-shift loads best managed with battery storage paired with solar.
Healthcare & Education
Manchester University NHS Foundation Trust operates 10 hospitals across Greater Manchester consuming enormous electricity volumes. The University of Manchester, Manchester Metropolitan University, and Salford University all have large flat-roof building stock. Salix Finance (interest-free loans for NHS and public bodies) covers 100% of project costs and is repaid from energy savings — contact us to discuss Salix-funded projects.
Hospitality & Leisure
Manchester's hotel and conference market — Deansgate, Piccadilly, NOMA and MediaCity — all has rooftop solar potential. Hotels running 24/7 aircon, laundry and kitchen loads achieve self-consumption rates of 60–75%. We have specific experience with Manchester hotel stock, including management of ENW grid applications for city centre sites with shared roof structures.
AIA Tax Relief: Manchester Commercial Solar Calculation
Annual Investment Allowance (AIA) provides 100% first-year tax deduction on commercial solar costs for businesses with a corporation tax liability. For Manchester businesses paying 25% CT rate:
- £75,000 system (100kWp): AIA saves £18,750 in year 1 → net cost £56,250 → payback on net cost 2.5–3.5 years
- £150,000 system (200kWp): AIA saves £37,500 → net cost £112,500 → payback 2.5–3 years
- £375,000 system (500kWp): AIA saves £93,750 → net cost £281,250 → payback 2.5–3 years
AIA applies to outright purchase and hire purchase (asset finance with ownership transfer). It does not apply to operating leases or PPAs. Read the full capital allowances guide.

Frequently Asked Questions
How much does commercial solar cost in Manchester?
Commercial solar in Manchester costs £750–£1,050 per kWp installed in 2026. A 100kWp system costs £75,000–£105,000 all-in including scaffolding, ENW G99 application, inverters and monitoring. At Greater Manchester electricity rates (~30p/kWh), savings are £18,000–£25,000 per year for a 100kWp system at 70% self-consumption. Payback is 3.5–5 years, or 2.5–4 years after AIA tax relief at 25% CT rate. Contact us for a detailed Manchester site assessment.
Who is the DNO for Manchester and how long does G99 take?
Greater Manchester is served by Electricity North West (ENW). For commercial solar with grid export above 3.68kW AC per phase, a G99 application to ENW is required. Standard ENW processing is 65 working days (~13 weeks). Network capacity in parts of Trafford Park (M17), Salford Quays (M50) and Manchester Airport (M90) should be pre-checked for large systems (250kWp+). We submit ENW pre-application feasibility queries and G99 applications as part of our standard project management.
Does Manchester get enough sunshine for commercial solar?
Yes. Greater Manchester generates approximately 870–910 kWh of electricity per kWp of solar capacity annually — around 10% less than London but commercially viable. A 100kWp system generates 87,000–91,000 kWh/year. At 30p/kWh with 70% self-consumption, this saves £18,270–£19,110 per year. Manchester's reputation for rain is slightly exaggerated — it receives 1,690 sunshine hours annually compared to 1,900 in London, and solar panels also generate from diffuse (overcast) light.
Can Manchester businesses get grants for commercial solar?
Yes. Manchester businesses can access: (1) Annual Investment Allowance — 100% first-year tax deduction on system cost, worth £18,750–£93,750 for a 100–500kWp system at 25% CT rate; (2) 0% VAT on solar installation; (3) Business rates exemption on solar equipment; (4) Smart Export Guarantee — income from exported electricity (3–18p/kWh); (5) IETF grants (for industrial sites using 1GWh+ annually); (6) Salix Finance — interest-free loans for NHS, councils, universities and schools.
Is Trafford Park suitable for commercial solar?
Yes — Trafford Park is one of the best commercial solar locations in the North West. Trafford Park industrial units and warehouses typically have large flat steel roofs and very high electricity consumption (manufacturing, refrigeration, logistics), giving self-consumption rates of 80–90%. ENW network capacity in parts of M17 should be checked for systems above 250kWp with export. We recommend zero-export configuration for any Trafford Park system where commissioning speed is a priority, with export added later once G99 is approved.
Warehouse Solar and Borough-by-Borough Coverage Across Greater Manchester
Beyond the Trafford Park core, the strongest warehouse solar opportunities in Greater Manchester sit on the region's modern logistics parks. Heywood Distribution Park (OL10) and Kingsway Business Park in Rochdale (OL16) host the large steel-portal sheds that suit roof-mounted PV best — clear spans, minimal rooflights and continuous pick-and-pack or chilled loads that lift self-consumption to 75–90%. A typical 200,000 sq ft Heywood warehouse comfortably carries a 500kWp array (£375,000–£500,000), generating around 450,000 kWh a year and saving £90,000–£126,000 at North West rates. Logistics North at Bolton (BL5), beside the M61, is one of the North West's biggest distribution clusters and a prime warehouse-solar location, while Wingates Industrial Estate at Westhoughton offers similar mid-box stock.
Every one of these sites connects to Electricity North West (ENW), so any export system above 3.68kW AC per phase needs a G99 application — ENW's standard timeline is 65 working days. We pre-check capacity on the OL10, OL16 and BL5 feeders before quoting, and offer a zero-export configuration where a fast commissioning date matters more than waiting for full export approval.
