Where businesses are in Bridgwater
- Bridgwater Gateway: 100 acre site in development close to the A38 and junction 24 of the M5, for offices and industrial units aimed at the Hinkley Point C supply chain.
- Express Park Industrial Estate: Industrial estate about 2.5 km north of the centre off Bristol Road (A38).
- Dunball Industrial Estate and Dunball Wharves: Industrial estate about 4 km north of the town next to Dunball Wharves, general cargo and aggregate berths on the River Parrett.
- Somerset Energy and Innovation Centre: Centre on Bristol Road with about 2,400 square metres of offices and business advice for the Hinkley Point C supply chain.
- Colley Lane Industrial Estate: Industrial estate about 1.3 km south east of the town centre.
Large employers and sectors with sites here include:
- Nuclear construction supply chain: Bridgwater is the closest retail and service centre to Hinkley Point C.
- Battery manufacturing: Agratas (Tata Group) is building a lithium-ion cell plant, around £4 billion of investment, at Gravity near junction 23 of the M5.
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.
Enterprise, investment and freeport zones
- Gravity Enterprise Zone (616 acres between Puriton and Woolavington, off junction 23 of the M5)
These zones can bring business rates relief or enhanced capital allowances for eligible firms on qualifying sites; check the current terms with the zone before relying on them.
Grid connection
Bridgwater is served by National Grid Electricity Distribution (South West). 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 Bridgwater
Bridgwater follows the national planning rules for England, decided by Somerset 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 Bridgwater Central Area and Dock conservation area covers the town centre.
- Tidal flood risk from the River Parrett: the Bridgwater Tidal Barrier Scheme aims to reduce flood risk to around 11,300 homes and 1,500 businesses, which matters for ground-mounted arrays.
- Quantock Hills National Landscape lies within about 5 km of the town.
Our guides on listed buildings and conservation areas, national parks and National Landscapes explain what these mean for a solar project.
What a business roof in Bridgwater could generate
Modelled with PVGIS for the town centre, a south-facing roof at 30 degrees produces about 1,044 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 104,400 kWh a year |
| Used on site | 70% at 24p = £17,539 saved |
| Exported | 30% at 5p = £1,566 earned |
| Total a year | About £19,105 |
| Simple payback | About 4.7 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 Bridgwater 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.
