Where businesses are in Pontypool
- Mamhilad Park Estate: A 140 acre business park owned by Johnsey Estates, with 180,000 sq ft of offices and over a million sq ft of industrial space. It says over 200 businesses are based there, about 10 miles from the M4.
- Panteg Industrial Estate and Panteg Way: Torfaen Council lets industrial units on Panteg Industrial Estate, Station Road, Griffithstown, and offices at Torfaen Business Centre on Panteg Way, New Inn.
Large employers and sectors with sites here include:
- Automotive parts (ZF Automotive): ZF Automotive UK's Pontypool plant mainly makes brake callipers. In June 2025 the Welsh Government gave it £432,000 to upgrade a production line for a Jaguar Land Rover contract, creating or keeping more than 60 jobs.
- Steel engineering (Pro Steel Engineering): Pro Steel Engineering is headquartered in Pontypool, with another office at Heathrow, and reported a £17m turnover in its latest year in February 2026.
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
Pontypool is served by National Grid Electricity Distribution (South Wales). 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 Pontypool
Planning in Pontypool is decided by Torfaen 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:
- Pontypool Town Centre is one of Torfaen's six conservation areas, and the borough has around 250 listed buildings and structures, so check a building's status before planning roof panels in the centre.
Our guides on listed buildings and conservation areas explain what these mean for a solar project.
What a business roof in Pontypool could generate
Modelled with PVGIS for the town centre, a south-facing roof at 30 degrees produces about 985 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 98,500 kWh a year |
| Used on site | 70% at 24p = £16,548 saved |
| Exported | 30% at 5p = £1,478 earned |
| Total a year | About £18,026 |
| Simple payback | About 5.0 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

Businesses must be based in Wales and have traded for at least two years with filed accounts. A grant of up to 50% of the cost of a detailed energy audit, to a maximum of £10,000, is also offered. Check the scheme's own page for eligibility and closing dates.
National reliefs apply too: see grants and reliefs in Wales.
