Commercial solar installers in Doncaster

Key facts

Where businesses are in Doncaster

• Total Park: A newly built industrial and logistics scheme of five units totalling 376,419 sq ft, about 1.5 miles from junction 3 of the M18, with eaves of 10 to 15 metres and yards up to 50 metres deep. Business Doncaster lists it among the city's centre opportunity sites.
• Parkside Business Park: A 27 acre St Modwen scheme off Wheatley Hall Road near the M18. Its second phase of 61,000 sq ft completed in 2018, when the first phase was fully let to Bosch Automotive and DB Schenker.

Large employers and sectors with sites here include:

• Rail (Hitachi Rail depot): Business Doncaster quotes Hitachi Rail saying 300 people are employed at its Doncaster depot, which maintains 65 trains for LNER, and says rail has been part of Doncaster's economy for over 150 years.
• Healthcare (Doncaster Royal Infirmary): Doncaster and Bassetlaw Teaching Hospitals has over 7,000 colleagues and serves more than 440,000 people; its Doncaster Royal Infirmary on Armthorpe Road has over 500 beds and a 24 hour emergency department.

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

Doncaster is served by Northern Powergrid (Yorkshire 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 Doncaster

Doncaster follows the national planning rules for England, decided by Doncaster 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 Doncaster High Street Conservation Area covers about 9.4 hectares of the centre and holds 47 listed buildings, including the Grade I Mansion House, so roofs in the historic core need more care.

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

What a business roof in Doncaster could generate

Modelled with PVGIS for the town centre, a south-facing roof at 30 degrees produces about 965 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 Doncaster 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.

At the end of 2025, Doncaster had 10,360 solar PV installations with 66.6 MW of capacity, up 52% since 2020, according to government figures. The Doncaster page has the full local figures and how they compare.
