Where businesses are in Wrexham
- Wrexham Industrial Estate: Large industrial estate whose occupiers include JCB. Its largest landowner, FI Real Estate Management, said in February 2025 it had invested more than £136m there over two decades and was building Wrexham 1M, one million sq ft of logistics space expected to create 1,000 jobs.
- Wrexham Technology Park: Office park where HMRC took grade A space at Yale Business Village on a 10 year lease in 2024; other occupiers include the Development Bank of Wales, Spire Yale Hospital, WSP, NFU Mutual and Chetwood Financial.
Large employers and sectors with sites here include:
- Food manufacturing (Jones Village Bakery): Jones Village Bakery's headquarters is on Wrexham Industrial Estate. In November 2025 its new £20 million production line was running, doubling roll-making capacity and set to create 60 jobs, as part of a £47 million investment.
- Sports equipment (Net World Sports): In October 2026 Wrexham Council unanimously approved Net World Sports' plan for a 14,564 square metre warehouse off Bryn Lane for manufacturing or distribution, creating between 205 and 438 jobs.
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
- Flintshire and Wrexham Investment Zone: One of its three tax sites covers various sites in the vicinity of Wrexham Industrial Estate, designated from 21 November 2025; tax reliefs can be claimed until 30 September 2034.
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
Wrexham 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 Wrexham
Planning in Wrexham is decided by Wrexham council under the Welsh rules. Many non-domestic roofs are covered by Welsh permitted development, with conditions, but not within 3 km of an airport or aerodrome or on listed buildings.
Points that come up locally:
- The Wrexham Town Centre Conservation Area, designated in 1974 and last extended in 2007, covers the main historic and commercial streets of the centre around St Giles' Church, so check whether a building is inside it before planning roof panels.
- Welsh Government guidance says solar panels on non-domestic buildings can be permitted development if they project no more than 200mm from the roof (1 metre above a flat roof) and sit at least 1 metre from the roof edge; listed buildings need consent, and in conservation areas panels on principal or side elevations visible from the highway need planning consent.
Our guides on listed buildings and conservation areas explain what these mean for a solar project.
What a business roof in Wrexham could generate
Modelled with PVGIS for the town centre, a south-facing roof at 30 degrees produces about 960 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 96,000 kWh a year |
| Used on site | 70% at 24p = £16,128 saved |
| Exported | 30% at 5p = £1,440 earned |
| Total a year | About £17,568 |
| Simple payback | About 5.1 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.
