Where businesses are in Bury St Edmunds
- Suffolk Park: A two million sq ft business park off the A14, with outline consent from 2017. Occupiers include Greene King, which leased a 160,000 sq ft warehouse there, plus Bleckmann, Skechers, Unipart, Sealey, Treatt and the East of England Ambulance Trust.
- Northern Way Industrial Estate: Established industrial area with easy access to the A14, mixing warehouses, car showrooms and trade counters, with neighbours including Mercedes-Benz, Volkswagen, Travis Perkins and Speedy Hire. In 2021 Savills IM bought five former Treatt buildings there (105,000 sq ft on 6.3 acres) to redevelop.
Large employers and sectors with sites here include:
- Brewing (Greene King): Greene King began building a £40m brewery on Suffolk Business Park in August 2025 to replace its town centre Westgate Brewery, with construction due to finish in 2027.
- Sugar (British Sugar): British Sugar is moving beet processing from its Cantley factory to Bury St Edmunds, Newark and Wissington, with Cantley due to close by the end of February 2027.
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
Bury St Edmunds is served by UK Power Networks (Eastern Power Networks). 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 Bury St Edmunds
Bury St Edmunds follows the national planning rules for England, decided by West Suffolk 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 Bury St Edmunds Town Centre Conservation Area was designated on 26 January 1973 and extended in 1975 and 1985, covering the Norman street grid, the Abbey precinct and surrounding streets. The appraisal says about a third of the borough's 3,000 plus listed buildings are in the town.
Our guides on listed buildings and conservation areas explain what these mean for a solar project.
What a business roof in Bury St Edmunds could generate
Modelled with PVGIS for the town centre, a south-facing roof at 30 degrees produces about 1,037 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 103,700 kWh a year |
| Used on site | 70% at 24p = £17,422 saved |
| Exported | 30% at 5p = £1,556 earned |
| Total a year | About £18,977 |
| 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 Bury St Edmunds 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.
