Commercial solar installers in Retford

Key facts

Where businesses are in Retford

• Trinity Park (Randall Way): A medium sized industrial estate of about 11.4 hectares on the northern edge of Retford, reached from North Road (A638) via Randall Way. The council's 2019 employment study described its units as modern and of high quality and recommended the site be protected for employment use.
• Hallcroft Industrial Estate: A local industrial estate of about 10.2 hectares off Hallcroft Road on the northern edge of the town, made up of small and medium sized industrial and warehouse units. The council's 2019 study found it intensively used with a high occupancy rate.
• West Carr Industrial Estate: About 12.4 hectares of small and medium sized industrial units of varying ages off West Carr Road, enclosed by railway lines and about a ten minute walk from Retford's two stations, according to the council's 2019 employment study.
• Retford Enterprise Centre: A council owned and managed business centre for small firms. A completed £1.45 million second phase added 686 square metres of new office and clean manufacturing space so occupants could move to larger units as they grow.

Large employers and sectors with sites here include:

• Engineering group head office (Langley Holdings): Langley Holdings plc, a family owned engineering and industrial manufacturing group with around 4,600 people across Power Solutions and Diverse Industrials divisions, has its registered head office on Enterprise Way, Retford.
• Polyurethane manufacturing (Trelleborg): Trelleborg opened a 7,225 square metre polyurethane manufacturing centre of excellence in Retford in March 2017, bringing four sites together, and a University of Nottingham research article describes its applied technologies business as Retford-based.

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

Retford is served by National Grid Electricity Distribution (East Midlands 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 Retford

Retford follows the national planning rules for England, decided by Bassetlaw 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 Retford Conservation Area, designated on 8 October 1973, covers about 84 hectares and holds 108 listed buildings, six of them Grade II* including the Parish Church of St Swithun, 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 Retford could generate

Modelled with PVGIS for the town centre, a south-facing roof at 30 degrees produces about 992 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 Retford 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.
