Commercial solar installers in Witney

Key facts

Where businesses are in Witney

• Windrush Park: Business park on Range Road, Witney. Abbott Diabetes Care Limited, a medical device manufacturer, has its registered office there.
• Witan Park Industrial Estate: Industrial and warehouse estate on Avenue Two, Station Lane, about half a mile from the A40, one of Indurent's estates. Its units have been refurbished, and nearby occupiers include Royal Mail, Travis Perkins and City Plumbing.

Large employers and sectors with sites here include:

• Medical devices (Abbott): Abbott Diabetes Care Limited, incorporated in 1990 and classed as a maker of medical and dental instruments and supplies, has its registered office at Windrush Park, Range Road, Witney.
• Engineering (Oxford Flow): Flow control equipment and valve specialist Oxford Flow moved into a new, larger headquarters in Witney in September 2025, bringing several local sites under one roof and strengthening its UK manufacturing; it reported a 52% rise in global headcount since January 2025.

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

Witney is served by SSEN Distribution (Southern Electric Power Distribution 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 Witney

Witney follows the national planning rules for England, decided by West Oxfordshire 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 Witney Conservation Area was designated in 1970, the first in West Oxfordshire, and extended in 1980, 1988 and 1990. The council's Witney and Cogges appraisal notes that the woollen blanket industry left mills, workers' houses and related buildings throughout the town, so older industrial and town centre roofs need more care.

Our guides on listed buildings and conservation areas explain what these mean for a solar project.

What a business roof in Witney could generate

Modelled with PVGIS for the town centre, a south-facing roof at 30 degrees produces about 1,013 kWh per kWp a year.

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 Witney 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.
