Solar Panels in Northampton for Homes and Businesses

Northampton commercial work concentrates around Brackmills (one of the UK's largest dedicated industrial estates), Moulton Park, Pineham Park and the Swan Valley distribution cluster along the M1.

What we install in Northampton

We install solar panels on Northampton homes and on commercial buildings: factories, warehouses, farm buildings and hospitality. We work with both single-house owner-occupiers and multi-site commercial operators across the area. Northampton warehouses and offices are part of our East Midlands commercial solar service area.

• Commercial roof PV — 30kWp to 1MWp+ installations on industrial, agricultural and hospitality buildings in Northampton
• Domestic solar PV — 3.4kWp to 8.6kWp on owner-occupied homes throughout NN1–NN5
• Battery storage — 5kWh to 215kWh on residential and commercial premises
• EV charging — OZEV-approved 7kW–22kW chargers, with home and workplace charging grants claimed on your behalf
• Grid connection support — G98 / G99 / G100 applications managed end-to-end with your local DNO

Solar panels in Northampton: the local facts

These are the figures we work from on a Northampton quote. Each one is sourced, and each was checked on 18 October 2026.

What solar panels generate in Northampton

PVGIS, the European Commission's solar model, gives Northampton about 1,023 kWh a year for every kWp of panels on a well-angled, unshaded roof. On those figures a 4 kWp home system produces roughly 4,092 kWh a year, and a 250 kWp warehouse roof at Brackmills or Moulton Park roughly 255,750 kWh. East-west, flat or shaded roofs produce less, so the drone survey sets the final number. Our solar calculator turns the yield into savings for your own bill.

Planning permission for solar panels in Northampton

Since April 2021 the planning authority for Northampton is West Northamptonshire Council, which lists 117 conservation areas across its area. In the town they include All Saints, around the Market Square, and the Boot and Shoe Quarter, designated in 2011 for the town's footwear factories and terraces. Outside designated areas and listed buildings, roof panels on a house are normally permitted development if they sit within 0.2 m of the roof surface.

Connecting solar to the grid in Northampton

Northampton is in National Grid Electricity Distribution's East Midlands licence area. Home systems up to 16A per phase are connected under G98 and notified after commissioning; larger home systems and every warehouse or factory roof need a G99 application approved by NGED first. Large distribution-centre roofs often need an export limit, which we design in from the start. Our grid connection page explains the process.

Northampton's climate plans and the grants open now

West Northamptonshire Council declared a climate emergency in 2021, but in August 2025 it dropped its local net zero targets (2030 for its own operations, 2045 for the area) as unaffordable and moved the money to walking and cycling, nature recovery and home energy efficiency. In Northampton, the case for solar rests on the bill savings rather than a council target. (West Northamptonshire Council: sustainability refocus (Aug 2025))

West Northamptonshire Council has £2.6 million of Warm Homes: Local Grant funding over three years, delivered with Sureserve Energy Services, for homes rated EPC D to G where household income is £36,000 or less, someone receives a means-tested benefit, or the home is in a priority postcode. The council's announcement lists insulation, draught proofing, smart controls and low-carbon heating; GOV.UK lists solar panels among the measures a survey can recommend. (GOV.UK: Apply for the Warm Homes: Local Grant · West Northamptonshire Council: Warm Homes Local Grant)

For a business, the tax position matters more than grants: solar is special-rate plant, so the Annual Investment Allowance, not Full Expensing, is the usual route; see our grants and tax relief guide. Homeowners can compare home solar panels; businesses can start with commercial solar panels or our East Midlands commercial solar page.

Industrial estates and commercial clusters we cover

Our commercial work in Northampton concentrates around Brackmills, Moulton Park, Pineham Park, Swan Valley. Each of these estates has different roof-stock characteristics, grid capacity profiles and tenant patterns — our drone-led survey approach adapts to all of them.

Local landmarks and orientation

For reference, we routinely work near these Northampton landmarks: Brackmills Industrial Estate, Moulton Park, Sixfields Stadium, Pineham Park, Northampton railway station. Our HQ in Newark-on-Trent sits 75 minutes from Northampton by road via the main routes, which means our drone-survey crew can be on site for a first visit inside two working days from initial enquiry.

Postcodes served

We routinely install across the following Northampton postcodes: NN1, NN2, NN3, NN4, NN5. The local council is West Northamptonshire Council, which is the planning authority for any installation requiring full planning permission (typically only listed buildings, conservation areas and ground-mount projects).

Nearby towns we also cover

Why Northampton customers choose KMM

Three things separate us from the larger national installers operating in Northampton:

1. Local presence. Our HQ is 75 minutes from your front door. Aftercare is not via a call-centre in Glasgow — it is the same person who designed your system.
2. Drone-led surveys. We survey every roof from the air. No ladders, no scaffold hire on the survey day, and a 3D model of your roof inside 48 hours.
3. Honest finance. Our quotes include the published commission, the alternative finance routes side-by-side and the cash model we used to calculate payback.
