Where businesses are in Bridport
- St Michael's Trading Estate: A trading estate of workshops and studios in Bridport's old industrial buildings, which had more than 100 businesses in 2023, when the Edwards Tower Building, refurbished after a 2018 fire, reopened to tenants.
- Old Laundry Trading Estate: Named in the Bridport Area Neighbourhood Plan (Policy EE1) as an important employment site, where business, industrial and storage uses are supported.
- East Road Trading Estate: Also named in Neighbourhood Plan Policy EE1 as an important employment site providing valuable workspace, where business, industrial and storage uses are supported.
Large employers and sectors with sites here include:
- Brewing (Palmers Brewery): Palmers is a family owned brewery founded in Bridport in 1794 and owned by the Palmer family since 1896. Its West Bay Road brewery is the UK's only thatched brewery, rethatched in summer 2025, and there are more than 50 Palmers pubs across the region.
- Engineered textiles (AmSafe Bridport): AmSafe Bridport, part of TransDigm since 2012, has its head office on West Street, Bridport, and makes engineered textile products such as cargo restraint, fire protection and cabin barrier systems for aviation and defence.
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
Bridport is served by National Grid Electricity Distribution (South West 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 Bridport
Bridport follows the national planning rules for England, decided by Dorset 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:
- Bridport Conservation Area is large at about 90.8 hectares and holds 376 listed buildings, including the Grade I Parish Church of St Mary and Town Hall, so many central roofs need more care; West Bay has its own conservation area too.
Our guides on listed buildings and conservation areas explain what these mean for a solar project.
What a business roof in Bridport could generate
Modelled with PVGIS for the town centre, a south-facing roof at 30 degrees produces about 1,106 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 110,600 kWh a year |
| Used on site | 70% at 24p = £18,581 saved |
| Exported | 30% at 5p = £1,659 earned |
| Total a year | About £20,240 |
| Simple payback | About 4.4 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
