Commercial solar installers in Newton Aycliffe

Key facts

Where businesses are in Newton Aycliffe

• Aycliffe Business Park: Large industrial estate south of the town at junction 59 of the A1(M), home to Hitachi Rail's 30 acre train factory.
• Merchant Park: 65 acre, £90 million development at Aycliffe Business Park, with serviced plots for buildings up to 350,000 sq ft and ten industrial starter units at Station Place.
• Forrest Park: 48 hectare site on the A167 south of Aycliffe Business Park next to junction 59 of the A1(M), consented for 1.7 million sq ft of B1, B2 and B8 floorspace with its own 24 MW substation.

Large employers and sectors with sites here include:

• Rail manufacturing: Hitachi Rail's UK train factory, opened in 2015.
• Advanced manufacturing and electrification: Business Durham lists Forrest Park and Merchant Park as key sites.

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

Newton Aycliffe is served by Northern Powergrid (Northeast). 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 Newton Aycliffe

Newton Aycliffe follows the national planning rules for England, decided by County Durham 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:

• No green belt, National Landscape or national park lies within about 10 km of the town centre.

Our guides on green belt, national parks and National Landscapes explain what these mean for a solar project.

What a business roof in Newton Aycliffe could generate

Modelled with PVGIS for the town centre, a south-facing roof at 30 degrees produces about 940 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

• Business Energy Efficiency Project (BEEP), Durham County Council: Independent energy audits, then through the Durham Business Growth programme grants of up to 40% of costs on projects up to £9,999 total (LED lighting, insulation, heating controls, solar PV), while funds last; the programme's third phase ends at the end of 2026. Check the scheme's own page for eligibility and closing dates.

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