Where businesses are in Northwich
- Gadbrook Park: A 100 hectare business park on the outskirts of Northwich, about five minutes' drive from the town centre, for office, research, finance, distribution and production uses. The council's draft local plan proposes keeping it safeguarded for employment.
- Winnington Business Park: A 7.5 acre scheme of eight blocks off Winnington Avenue, where developer FIREM broke ground in 2022 on about 113,000 sq ft of trade and industrial units.
Large employers and sectors with sites here include:
- Chemicals (Tata Chemicals Europe): In June 2022 Tata Chemicals Europe opened a carbon capture and usage plant in Northwich, designed to capture 40,000 tonnes of CO2 a year from its Winnington combined heat and power plant to make high purity sodium bicarbonate.
- Accountancy and business advice: In September 2025 accountants WR Partners moved their Northwich team to new, larger offices at 3 Royal Court, Gadbrook Park, citing growth and rising demand.
Large, simple roofs on distribution sheds and modern industrial units are usually the quickest and cheapest to fit. Older mill, factory and workshop buildings can work well too, but often need a structural survey first, and roofs from before 2000 may contain asbestos cement: see asbestos roofs.
Grid connection
Northwich is served by SP Energy Networks (SP Manweb, Merseyside and North Wales licence area). Almost every commercial system needs G99 approval from the network operator before it is switched on, and the question is usually how much the local network can take back. Where export is limited, a G100 export limitation scheme can let a larger array connect. See G99 and DNO applications.
Planning in Northwich
Northwich follows the national planning rules for England, decided by Cheshire West and Chester council. Rooftop solar on most non-domestic buildings is permitted development, within height and edge limits, and systems above 50 kW need a prior approval application covering design and glare.
Points that come up locally:
- Cheshire West and Chester's local plan policy N 6 sets criteria for development in the Northwich conservation area, and the council proposes keeping it to protect the character of the town centre and its outskirts, so roofs in the centre need more care.
Our guides on listed buildings and conservation areas explain what these mean for a solar project.
What a business roof in Northwich could generate
Modelled with PVGIS for the town centre, a south-facing roof at 30 degrees produces about 934 kWh per kWp a year.
| Item | Illustrative figure |
|---|---|
| System | 100 kWp, south facing at 30 degrees |
| Installed cost | £900 per kWp, so £90,000 excluding VAT |
| Generation | About 93,400 kWh a year |
| Used on site | 70% at 24p = £15,691 saved |
| Exported | 30% at 5p = £1,401 earned |
| Total a year | About £17,092 |
| Simple payback | About 5.3 years before tax relief |
Illustrative, not a quote: the same sums as our commercial solar calculator. A company paying corporation tax can usually shorten the payback with capital allowances.
Funding and support
We found no council or regional grant for business solar open in Northwich at the time of writing (November 2026). National reliefs still apply, such as capital allowances and, in England, the business rates exemption for onsite renewables: see grants and reliefs in England.
