Where businesses are in Penrith
- Gilwilly Industrial Estate and Eden Business Park: The key employment area to the north of Penrith. The Eden Local Plan 2014 to 2032 allocates an 11.91 hectare extension to the Gilwilly estate, and at 31 March 2025 the council recorded development ongoing on Eden Business Park Phase 2, with 2.2 hectares left.
- Skirsgill: A 3.29 hectare employment allocation beside the Skirsgill depot, south of the A66, which the council recorded as still vacant at 31 March 2025.
Large employers and sectors with sites here include:
- Agricultural auctions and land agency (Penrith Farmers' & Kidd's): PFK, founded in 1876, has its head office at Agricultural Hall, Skirsgill, covers six areas from three linked offices and marks 150 years in 2026.
- Holiday parks (Center Parcs Whinfell Forest): Whinfell Forest, south east of Penrith, holds the largest of Center Parcs' five UK holiday villages, with 861 units sleeping 4,668 people.
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
Penrith is served by Electricity North West (North 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 Penrith
Penrith follows the national planning rules for England, decided by Westmorland and Furness 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 Penrith Conservation Area, designated in 1975, covers about 35.4 hectares and holds 136 listed buildings, three of them Grade I including the parish church of St Andrew, so roofs in the town centre need more care.
Our guides on listed buildings and conservation areas explain what these mean for a solar project.
What a business roof in Penrith could generate
Modelled with PVGIS for the town centre, a south-facing roof at 30 degrees produces about 896 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 89,600 kWh a year |
| Used on site | 70% at 24p = £15,053 saved |
| Exported | 30% at 5p = £1,344 earned |
| Total a year | About £16,397 |
| Simple payback | About 5.5 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 Penrith 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.
