Commercial Solar Installers in the East Midlands

Why the East Midlands suits commercial solar in 2026

Three structural factors make the East Midlands a strong region for commercial solar in 2026. First, the regional networks (National Grid Electricity Distribution, formerly Western Power Distribution, and Northern Powergrid in the far north of Lincolnshire) are generally less constrained than London and the South East, though every site still needs its own G99 check. Second, the regional economy is heavily weighted toward sectors with strong solar economics: food production (Lincolnshire), automotive supply chain (Derby), logistics (Northampton, Doncaster), agriculture (across Notts, Lincs, Cambs) and distribution (Magna Park, iPort, Brackmills). Third, councils and growth hubs across the region run business decarbonisation grant rounds from time to time; we check what is open for your postcode at the survey.

How KMM works across the region

Our HQ is in Newark-on-Trent. From there our drone-survey crew covers commercial sites across Nottinghamshire, Lincolnshire, Leicestershire, Derbyshire, parts of South Yorkshire, the West Midlands fringe and the southern Lincolnshire fens. For projects above 250kVA we will travel further — into Cambridgeshire, Norfolk and the Thames Valley — where the project economics justify it. For how we design and finance a system once the survey is done, see commercial solar panels for business.

What a commercial system generates in the East Midlands

The region sits in the middle of the UK range for solar yield. We use the European Commission's PVGIS tool for every first estimate; for a well-angled, unshaded array it gives these annual figures:

Source: PVGIS v5.2, 1 kWp crystalline silicon, optimal tilt (about 41°), 14% system losses, queried 18 October 2026. Flat-roof, east-west and shaded layouts produce less, so the survey decides the final figure.

A worked example: a 100 kWp factory roof near Newark

At about 1,000 kWh per kWp, a 100 kWp system produces roughly 100,000 kWh a year. A site that runs in the daytime, as most factories and warehouses do, uses most of that on site and avoids buying it from the grid; the surplus earns an export payment. On the tax side, the Annual Investment Allowance gives a 100% first-year deduction on qualifying spend, so at 25% corporation tax every £100,000 of qualifying cost can cut the tax bill by up to £25,000. Our commercial solar calculator runs the same sums for your own bill.

Grid connection in the East Midlands

Most of the region is in National Grid Electricity Distribution's East Midlands licence area (formerly Western Power Distribution); the far north of Lincolnshire is Northern Powergrid. Any system above 16A per phase needs a G99 application before it connects, and larger sites often need an export limit agreed with the DNO. We prepare the application as part of every project; our grid connection consultancy page explains the process and the DNO application timelines guide covers what slows it down.

Across the five counties

Nottinghamshire. Our base is at North Muskham, a few minutes north of Newark, so Nottinghamshire sites get the shortest survey lead times. Businesses here should also check the Nottinghamshire net zero business grants guide.

Lincolnshire. Farming and food production dominate, so most enquiries are barns, cold stores and processing sites; see solar for farms and the Lincolnshire rural business grants guide.

Leicestershire and Northamptonshire. Logistics parks such as Magna Park near Lutterworth and Brackmills in Northampton mean large, flat warehouse roofs with daytime loads; see solar for warehouses.

Derbyshire. Manufacturing sites with steady weekday demand suit self-consumption-led designs; see solar for factories.

Homes as well as businesses. Our city pages cover solar panels in Nottingham, solar panels in Leicester, solar panels in Lincoln, solar panels in Northampton, each with the city's own yield, planning, grid and grant facts.

Commercial work in the region

At The Deepings Practice, a doctors' surgery in Market Deeping, south Lincolnshire, we replaced a failing system with a 100 kW array and battery backup. Read the surgery solar rescue and the Deepings Practice install, or browse all case studies.

East Midlands commercial solar FAQs

Do you install commercial solar across the whole East Midlands?

Yes. KMM is based at North Muskham, near Newark-on-Trent, and surveys and installs commercial systems across Nottinghamshire, Lincolnshire, Leicestershire, Derbyshire and Northamptonshire. Every project starts with a free drone survey and a structural check.

How much electricity does a commercial solar system generate in the East Midlands?

PVGIS puts a well-angled, unshaded system in the region at roughly 980 to 1,020 kWh per kWp per year, so a 100 kWp roof produces around 98,000 to 102,000 kWh a year. Flat roofs, east-west layouts and shading lower that, which is why we model each roof from the survey.

Who is the DNO for commercial solar in the East Midlands?

Most of the region is in National Grid Electricity Distribution's East Midlands licence area. The far north of Lincolnshire is served by Northern Powergrid. Systems above 16A per phase need a G99 application to the DNO before they connect; we prepare and submit it as part of the project.

What tax relief applies to commercial solar?

Solar PV and batteries are special-rate plant, so Full Expensing does not apply. The Annual Investment Allowance gives a 100% first-year deduction on up to £1m of qualifying spend a year, so for a company paying 25% corporation tax, each £100,000 of qualifying spend can reduce the tax bill by up to £25,000.

Free regional commercial assessment

Tell us your site postcode and MPAN and we will run a desktop assessment inside 5 working days. No deposit, no pressure, no obligation to proceed. The assessment costs us roughly £180 in surveyor time; we deliver it free because the conversion rate from desktop to signed contract on commercial projects justifies the cost.
