Commercial solar installers in Mold

Key facts

Where businesses are in Mold

• Mold Business Park: A compact office and industrial park off the A494, a Principal Employment Area in Flintshire's Local Development Plan, which also allocates a further 3.90 hectares there for business, industry and storage.
• Mold Industrial Estate: A fully developed, established business park and industrial estate split into two sections along Queen's Lane and bounded by housing and the A494, meeting local needs for offices and mid-sized industrial premises.
• Broncoed Industrial Estate: A small, modern local employment area with workshop premises for local firms and office units to the rear, protected as a Principal Employment Area.

Large employers and sectors with sites here include:

• Arts and culture (Theatr Clwyd): Theatr Clwyd's £50 million redevelopment, due to reopen in June 2025, was expected to create 100 jobs and up to £30 million a year for the local economy, with solar power, air source heating and rainwater harvesting making it a fossil-free building.
• Local government (Flintshire County Council): Shire Hall in Mold, next to Theatr Clwyd in the civic complex, is home to Flintshire County Council.

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

Mold is served by SP Energy Networks (SP Manweb, Merseyside and North Wales 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 Mold

Planning in Mold is decided by Flintshire council under the Welsh rules. Many non-domestic roofs are covered by Welsh permitted development, with conditions, but not within 3 km of an airport or aerodrome or on listed buildings.

Points that come up locally:

• Mold's town centre is one of Flintshire's 32 conservation areas, one of only three covering the centres of historic market towns, so check whether a building is inside it before planning roof panels.
• In Wales, panels on a non-domestic building are usually permitted development if they project no more than 200mm from the roof or wall (1 metre above a flat roof) and sit at least 1 metre from the roof edge, but in a conservation area panels on a principal or side elevation wall need planning consent, and a listed building needs planning permission and listed building consent.

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

What a business roof in Mold could generate

Modelled with PVGIS for the town centre, a south-facing roof at 30 degrees produces about 961 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

• Development Bank of Wales Green Business Loan Scheme: Discounted fixed rate green loans, as part of a funding package with consultancy support, for energy efficiency measures and low carbon projects, with renewables including solar PV listed as typical eligible projects; repayments can start with a capital repayment holiday and the term is tied to the project's payback period. Limited companies, sole traders and partnerships must be based in Wales, have traded for at least two years and have at least one set of filed annual accounts. A grant of up to 50% of the cost of a detailed energy audit, to a maximum of £10,000 (£20,000 total costs), is also offered. Check the scheme's own page for eligibility and closing dates.

National reliefs apply too: see grants and reliefs in Wales.
