Commercial solar installation across the East Midlands, explained. Nottingham, Derby, Leicester, Lincoln, Northampton and all surrounding areas. NGED G99 connections explained.
Quick Answer
Which commercial solar installers cover the East Midlands?
This guide covers commercial solar across the full East Midlands region — Nottinghamshire, Derbyshire, Leicestershire, Lincolnshire, Northamptonshire, and Rutland. Most of the region is on the National Grid Electricity Distribution (NGED) network — distributor ID 11 on your MPAN — and installers manage the G99 application; allow several months for a connection offer on larger systems. The East Midlands has strong solar irradiance of approximately 980–1,030 kWh/m²/year. A 100kWp East Midlands system generates approximately 86,000–91,000 kWh/year, saving a business paying 30p/kWh around £25,800–£27,300 annually.
Commercial Solar in the East Midlands
The East Midlands is one of the UK's most active commercial solar markets, driven by a combination of strong industrial heritage, significant manufacturing and logistics clusters, and competitive land/building costs that make solar viable across a wide range of site types.
Key East Midlands solar drivers include: the East Midlands Gateway logistics hub (near Castle Donington), major manufacturing concentrations in Derbyshire (Toyota, Rolls-Royce), Leicestershire (pharmaceutical and food manufacturing), and Northamptonshire's logistics corridor (Daventry International Rail Freight Terminal). These industrial clusters generate substantial energy demand that solar can efficiently offset.

Grid Connection: NGED G99 in the East Midlands
Commercial solar systems over 50kWp in the East Midlands require a G99 grid connection application to the Distribution Network Operator. For most of the East Midlands that is National Grid Electricity Distribution (NGED, formerly Western Power Distribution) — the first two digits of the distributor ID on your MPAN read 11; the far north of Lincolnshire sits in Northern Powergrid's area. Capacity varies substation by substation, so ask for NGED's current connection offer timescale for your site.
NGED G99 process for East Midlands commercial solar:
- Pre-application feasibility: Good installers submit a pre-application query to NGED to check connection feasibility before formal application. This typically takes 4–6 weeks and identifies any potential grid constraints early.
- Formal G99 application: Submitted with full technical specifications. NGED review period is typically 12–16 weeks from submission.
- Protection relay coordination: Required for systems over 50kWp. Good installers specify the appropriate relay and metering arrangement to NGED's requirements.
- Total timeline: 16–24 weeks from initial engagement to formal approval.
In the East Midlands logistics corridor (Northampton, Daventry, Corby, Kettering), significant grid capacity has been allocated to new industrial development, meaning solar connections are generally straightforward. The Derbyshire industrial areas around Toyota (Burnaston) and Rolls-Royce (Derby) have more complex grid arrangements, so ask installers for experience on these networks.
Funding for East Midlands Manufacturers
The East Midlands has a high concentration of energy-intensive manufacturers — aerospace (Rolls-Royce, Derby), automotive (Toyota, Derbyshire), pharmaceutical (Boots, Nottingham) and food production across Lincolnshire, Leicestershire and Northamptonshire. Many older guides point these sites at the Industrial Energy Transformation Fund, but it closed in July 2025 with no successor fund, and its last window shut in April 2024. The relief that applies now is the Annual Investment Allowance (100% in year one, up to £1m), with the 50% special-rate first-year allowance above the cap.
What makes an East Midlands factory project work is the same as anywhere: a daytime process load that the array offsets, a roof with at least ten years of life left, and a G99 connection NGED can offer on your timetable.
East Midlands Commercial Property Types
Logistics and Warehousing (Northamptonshire, Leicestershire)
The M1/A14/M6 corridor through Northamptonshire and Leicestershire contains some of the UK's highest concentrations of logistics buildings. These offer very large, typically flat, south-facing roofs with excellent solar potential. The challenge: logistics tenancies are often short-term, making landlord-tenant agreement on solar installation essential. Ask your installer about landlord consent structures and lease-linked solar arrangements that protect both parties.
Manufacturing (Derbyshire, Nottinghamshire)
Derby's aerospace and automotive manufacturing base includes many modern factory buildings with metal roof construction — ideal for clamped solar systems. Rolls-Royce and Toyota supply chain manufacturers are active commercial solar adopters in the area, driven by Scope 2 supply chain requirements from the tier-1 OEMs.
Food Production (Lincolnshire, Northamptonshire)
Lincolnshire's significant food processing industry — fresh produce, packing, processing — generates substantial electricity demand during harvest and year-round cold storage operations. Lincolnshire's relatively flat agricultural terrain also makes it one of the best UK regions for solar irradiance.
Retail Parks (Regional)
The East Midlands has major retail park concentrations around Nottingham (Victoria Retail Park, Riverside Retail), Leicester (Fosse Park — one of the UK's largest), and Northampton (St James Retail Park). Retail park roofs are excellent solar candidates; planning and lease arrangements with REIT landlords are the primary consideration.

Frequently Asked Questions
Which DNO covers the East Midlands for G99 applications?
Most of the East Midlands is served by National Grid Electricity Distribution (NGED, formerly Western Power Distribution) — distributor ID 11 on your MPAN — with the far north of Lincolnshire in Northern Powergrid's area. Commercial systems above the G98 limit (16 A per phase, about 3.68 kW per phase) need a G99 application. Installers manage G99 submissions, protection relay coordination and DNO correspondence on behalf of East Midlands clients. Allow several months from formal submission for a G99 connection offer on larger systems.
Is the East Midlands a good area for commercial solar?
Yes. The East Midlands has solar irradiance of 980–1,030 kWh/m²/year — broadly similar to the Midlands average and approximately 10–15% less than the South Coast. This generates strong financial returns: a 100kWp system generates 86,000–91,000 kWh/year. Combined with the region's high concentration of daytime-load manufacturers, the East Midlands is one of the UK's most active commercial solar markets.
Do Nottingham and Leicester city centre buildings qualify for commercial solar?
Yes, many city centre commercial buildings qualify for permitted development solar installation. Key considerations for city centre buildings: listed building status (requires full planning consent), conservation area designation (roof panels stay permitted development, but not panels on a wall fronting a highway), roof structural capacity, and planning policy for the specific local authority (Nottingham City Council and Leicester City Council both have positive renewable energy policies). Ask the installer to confirm the planning position as part of the quote.
Are there grants for Derbyshire manufacturers?
Not a capital grant for solar in 2026. The Industrial Energy Transformation Fund, which older guides cite for ESOS-obligated manufacturers, closed in July 2025 with no successor fund. Derbyshire manufacturers claim the Annual Investment Allowance — 100% of the cost against taxable profits in year one, up to £1m — and the automotive and aerospace supply chains around Toyota and Rolls-Royce drive demand for Scope 2 reductions regardless of grants.
What size system does a typical East Midlands warehouse need?
A typical 5,000m² single-storey East Midlands logistics warehouse uses 400,000–800,000 kWh/year. A solar system sized at 150–250kWp is typical, offsetting 50–65% of daytime consumption. At 30p/kWh, this saves £40,000–£65,000/year. Battery storage can extend self-consumption to 70–80% by storing afternoon surplus for nighttime forklift charging. Payback for most East Midlands warehouse systems: 3–4 years.
