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
- Liverpool City Region Freeport (Wirral Waters tax site; the former Mersey Waters Enterprise Zone has been subsumed into it)
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
Birkenhead is served by SP Energy Networks (SP Manweb: Merseyside, Cheshire and North 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 Birkenhead
Birkenhead follows the national planning rules for England, decided by Wirral 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 centre includes the Hamilton Square conservation area, with Grade I listed buildings.
- Green belt (Wirral) lies within about 4 km of the town centre.
Our guides on listed buildings and conservation areas, green belt explain what these mean for a solar project.
What a business roof in Birkenhead could generate
Modelled with PVGIS for the town centre, a south-facing roof at 30 degrees produces about 951 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 95,100 kWh a year |
| Used on site | 70% at 24p = £15,977 saved |
| Exported | 30% at 5p = £1,427 earned |
| Total a year | About £17,403 |
| Simple payback | About 5.2 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 Birkenhead 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.
