Where businesses are in Bangor
- Balloo Industrial Estate: Industrial estate in Bangor. McWhinney's Sausages announced £2.2 million of new machinery at its Balloo factory in January 2026, with a £612,000 Invest NI grant, to double its capacity.
- Balloo South Industrial Estate: Unserviced 19.1 acre (7.73 hectare) site on the Newtownards Road, available for leasing to Invest NI client companies.
Large employers and sectors with sites here include:
- Advanced engineering and manufacturing: In the North Down constituency, advanced engineering and manufacturing took 28% of Invest NI assistance from 2021-22 to 2025-26, and Munster Simms Engineering was among the top investors.
- Food manufacturing: McWhinney's Sausages is investing £2.2 million at its Balloo Industrial Estate factory to double capacity and automate key processes, creating four roles.
- Digital and creative technologies: Digital and creative technologies accounted for 37% of the new jobs Invest NI supported in North Down from 2021-22 to 2025-26.
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
Bangor is served by NIE Networks, which runs the network across Northern Ireland. Systems connect under the G98/NI and G99/NI process, and there is no Smart Export Guarantee in Northern Ireland, so sizing the system to the power you use on site matters even more. See G99 and DNO applications.
Planning in Bangor
Planning in Bangor is decided by Ards and North Down council. Rooftop solar on many non-domestic buildings can go ahead without an application within the Northern Ireland limits; listed buildings need consent.
Points that come up locally:
- None of the three conservation areas the council lists (Donaghadee, Holywood and Portaferry) is in Bangor, so conservation area rules rarely affect its business roofs.
Our guides on listed buildings and conservation areas explain what these mean for a solar project.
What a business roof in Bangor could generate
Modelled with PVGIS for the town centre, a south-facing roof at 30 degrees produces about 936 kWh per kWp a year.
| Item | Illustrative figure |
|---|---|
| System | 100 kWp, south facing at 30 degrees |
| Installed cost | £900 per kWp, so £90,000 excluding VAT |
| Generation | About 93,600 kWh a year |
| Used on site | 70% at 24p = £15,725 saved |
| Exported | 30% at 5p = £1,404 earned |
| Total a year | About £17,129 |
| Simple payback | About 5.3 years before tax relief |
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
- NISEP Commercial Energy Saving Scheme (2026/27): A Northern Ireland Sustainable Energy Programme grant of 20% for commercial and non-domestic properties anywhere in Northern Ireland, with the applicant paying 80%. Measures include solar PV (grant capped at £30,000), boiler replacement, intelligent heating controls and lighting. Applications go to Power NI. The list of schemes covers April 2026 to March 2027. Check the scheme's own page for eligibility and closing dates.
National reliefs apply too: see grants and reliefs in Northern Ireland.
