Where businesses are in Leighton Buzzard
- Grovebury Road industrial area: Industrial and trade counter area along Grovebury Road. In December 2025 Kirkby Diamond let three units there, of 20,851, 18,399 and 8,662 sq ft, to Global Parts-UK, On The Level and Klas Steel within three months of the previous occupier, George Browns, leaving.
- Apex Park: Industrial estate fronting Leighton Road, owned by Pears Property Advisors. In April 2021 a £10 million scheme of 13 business units totalling 57,100 sq ft, the first development of small business units in the town for over 20 years, reached practical completion there.
Large employers and sectors with sites here include:
- Silica sand quarrying (Garside Sands, Holcim): Holcim's Garside Sands brand quarries silica sand at Leighton Buzzard from the Lower Greensand. An August 2025 Holcim data sheet gives its washed fine sand a silica content of 94.6%.
- Manufacturing and steel fabrication: In late 2025 Klas Steel, a bespoke steel fabrication and structural steelwork specialist, and On The Level Limited, described as a leading UK manufacturer, took units of 8,662 and 18,399 sq ft on Grovebury Road.
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
Leighton Buzzard is served by UK Power Networks (Eastern Power Networks 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 Leighton Buzzard
Leighton Buzzard follows the national planning rules for England, decided by Central Bedfordshire 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:
- Leighton Buzzard Conservation Area, designated in 1970, covers about 20.9 hectares of the town centre and holds 87 listed buildings, including the Grade I Church of All Saints and the Grade II* Market Cross, so roofs inside it need more care.
Our guides on listed buildings and conservation areas explain what these mean for a solar project.
What a business roof in Leighton Buzzard could generate
Modelled with PVGIS for the town centre, a south-facing roof at 30 degrees produces about 1,010 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 101,000 kWh a year |
| Used on site | 70% at 24p = £16,968 saved |
| Exported | 30% at 5p = £1,515 earned |
| Total a year | About £18,483 |
| Simple payback | About 4.9 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
We found no council or regional grant for business solar open in Leighton Buzzard 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.
