Where businesses are in Chester
- Chester West Employment Park: 34 hectare employment park on Sealand Road about a mile from the city centre, mixing light industrial, office and commercial units (B1, B2 and B8 uses).
- Sealand Industrial Estate: Long established industrial estate about a mile south west of the centre off the A540, with B1, B2 and B8 uses and a growing amount of non-food retail near Greyhound Retail Park.
- Chester Business Park: Large office park just off the A55 about two miles from the city centre, home to UK and European headquarters and call centres.
- Chester Gates: Business park of office, warehouse, distribution and storage units reached off the A5117, about two miles from junction 10 of the M53.
Large employers and sectors with sites here include:
- Financial services: Bank of America at Chester Business Park (Herons Way).
- Visitor economy: Chester Zoo, the most visited paid attraction in England outside London (1,947,544 visitors in 2024).
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
Chester is served by SP Energy Networks (SP Manweb). 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 Chester
Chester 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:
- The historic city core inside the City Walls is protected by local plan policy CH 1, and policy CH 6 protects 30 key views and the skyline from taller development.
- The Chester City Centre conservation area covers the centre.
- The North Cheshire Green Belt draws Chester's settlement boundary, so open land around the city is green belt.
Our guides on listed buildings and conservation areas, green belt explain what these mean for a solar project.
What a business roof in Chester could generate
Modelled with PVGIS for the town centre, a south-facing roof at 30 degrees produces about 951 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 95,100 kWh a year |
| Used on site | 70% at 24p = £15,977 saved |
| Exported | 30% at 5p = £1,427 earned |
| Total a year | About £17,403 |
| Simple payback | About 5.2 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 Chester 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.
