Solar panels for cold storage in Leicester

A guide to solar for cold stores in Leicester and the wider Leicestershire area, including Loughborough, Hinckley, Coalville.

Why solar PV makes sense for Leicester cold storage operators

Leicester sits in the heart of the East Midlands, on the M1 and within reach of the M69 and M6, in what is often called the golden triangle of UK logistics. More of the country’s distribution capacity is concentrated within a short drive of Leicester than almost anywhere else, and a great deal of it is cold. The city’s chilled and frozen warehouses serve the East Midlands grocery network, a strong local food manufacturing base and the national distribution that flows through the region. Refrigerated buildings run their plant continuously, day and night, which is a load profile that tends to suit rooftop solar better than a daytime-only ambient load. A cold store tends to use most of what its roof can generate, so the panels offset grid electricity at the full retail rate rather than exporting cheaply.

A typical Leicester commercial site averages around £38,000 a year on electricity, but a refrigerated facility runs far higher, often into the hundreds of thousands, because continuous freezing is so energy-intensive. Network charges (TNUoS and BSUoS) are a component of the delivered electricity price in East Midlands tariffs and change each year, and every kilowatt-hour generated and used on site avoids both the energy and network components. For a 24/7 cold store, the illustrative model assumes a high share of generation (about 90%) is used on site; test that against twelve months of half-hourly meter data. The illustrative payback of around four to five years in the site’s simple model (assumed tariff and self-consumption; not a quote) is sensitive to that assumption.

Leicester’s cold chain geography, where the roofs are

The city’s modern distribution capacity gathers in business parks with strong M1 links. Optimus Point and Meridian Business Park to the west, near the M1 and the A46, are major modern logistics locations with large clear-span warehouses ideal for solar. Beaumont Leys to the north-west holds a mix of distribution and manufacturing, while Frog Island near the centre and Leicester Commercial Square carry older industrial stock.

The buildings range from heritage manufacturing units with asbestos cement roofs that need a combined re-roof before solar, to modern composite-panel cold stores ready for a ballasted array. Beyond the city, the cold storage that supplies Leicester reaches out along the M1 toward Loughborough, Hinckley and the wider golden-triangle logistics belt, and many Leicester operators run portfolios across these areas.

Planning and local funding for Leicester cold stores

In England, roof-mounted solar on a non-domestic building such as a Leicester cold store is normally permitted development under Class J of Part 14 of the GPDO 2015; an array above 50 kW needs the council’s prior-approval decision on design and external appearance, including glare. Planning is therefore rarely the main obstacle, but the prior-approval step should be allowed for in the programme. Regional grant support changes year to year, so current eligibility is worth checking before a project is costed.

Local cost data: illustrative figures for Leicester cold storage

A mid-sized Leicester refrigerated facility typically spends £65,000 to £290,000 a year on grid electricity, with the larger frozen distribution hubs serving the East Midlands grocery network running above that. East Midlands tariffs include network charges as part of the delivered price, and the continuous load of refrigeration leaves no off-peak window to exploit.

For a Leicester cold store solar install in 2026, indicative cost per kilowatt sits at:

• £750 to £950 per kW for systems of 400 to 800 kW, the single-facility range used in the illustrative model (a modelling assumption, not a quote or a market survey)
• £700 to £850 per kW for systems above 1 MW at the larger frozen distribution hubs, also an illustrative modelling assumption
• A modelled reduction toward £600 per kW at the very largest regional sites (an illustrative assumption, not a quote)

Illustratively, a Leicester limited company claiming the 100% Annual Investment Allowance on a solar system could see an effective tax saving of up to 25% in year one, with most systems claimed against profits in the first year. Our cost guide sets out the detail, and the grants and funding page covers the wider funding position. The Industrial Energy Transformation Fund closed in July 2025 and no successor fund is planned, so it cannot be counted on; check GOV.UK for any scheme open now. The longest item on a Leicester project is typically the National Grid Electricity Distribution G99 connection, so the application is best made early.

An illustrative Leicester example, an Optimus Point frozen distribution warehouse

Picture a frozen distribution warehouse at Optimus Point, beside the M1, serving the East Midlands grocery network. The building is a clear-span steel-portal structure of around 4,800 square metres, holding frozen chambers at minus 25 degrees and running its refrigeration plant continuously for overnight deliveries into regional supermarkets. Annual grid consumption sits near 1.1 million kWh, dominated by the freezing load.

In this illustrative case, a 620 kW rooftop array across the usable roof would be expected to generate roughly 560,000 kWh a year in the East Midlands climate. Because the freezing plant never switches off, the illustrative model assumes about 90% of that generation is used on site (to be tested against twelve months of half-hourly meter data), so most of it displaces grid electricity at the full retail rate. At an assumed current East Midlands tariff that would be expected to save around £118,000 a year, giving an illustrative simple payback inside five years in the site’s simple model (not a quote). A design of this kind would typically use a non-penetrating ballasted mount to protect the insulated roof and structural loading verified to the building’s capacity; ask the site’s insurer and a fire-protection engineer about roof loading, clearances and sprinkler compatibility before design.

Postcodes and industrial areas across Leicester

Cold storage solar is relevant across all Leicester postcode districts, with the heaviest demand in the industrial belts:

• West: LE19 around Optimus Point and Meridian Business Park, the city’s largest modern distribution cluster
• North-west: LE4 around Beaumont Leys and the northern industrial estates
• Central: LE3 around Frog Island and Leicester Commercial Square
• South: LE2 and LE18 around Oadby and Wigston industrial pockets
• Outer: LE8 and LE9 around the M1 and M69 logistics belt for larger sites

Rooftop installation takes place above the cold chain, so refrigeration and despatch can usually continue uninterrupted.

Other cold storage areas adjoining Leicester

The cold storage that supplies Leicester extends across the East Midlands golden triangle, and many operators run several sites. Refrigerated warehouse solar is also relevant in:

• Loughborough, the M1 corridor distribution and food logistics estates
• Hinckley, the M69 logistics concentration and the DIRFT-adjacent distribution belt
• Coalville, the A42 and M1 corridor distribution serving the north of the county
• Market Harborough, the southern Leicestershire food and chilled logistics
• Coventry and Northampton, the wider golden-triangle cold chain a short drive away

Each falls under a different council, so planning decisions and local policy can differ from site to site in an East Midlands portfolio.

Frequently asked questions about Leicester cold storage solar

How long does the grid connection take in Leicester? National Grid Electricity Distribution is the DNO across Leicester, and G99 connection timescales for larger systems run several months on capacity-constrained parts of the network. The application is normally submitted immediately after the survey to start the clock.

Can I install on a leased cold store at Optimus Point or Meridian? Yes. Tenant solar is standard practice and needs landlord consent, granted by most institutional landlords under the BBP Green Lease Toolkit. For shorter leases a power purchase agreement is often the better route. Landlord consent is best sought early.

Will installation disrupt our cold chain? No. The array sits above your operations, so refrigeration, picking and despatch carry on. The only outage is a few hours for final grid synchronisation, scheduled for a weekend or planned shutdown.

Send an enquiry about your Leicester cold storage solar project

Commercial solar is relevant across Leicester and the wider East Midlands cold chain, from Optimus Point to Beaumont Leys, from Meridian Business Park to the M1 corridor. An initial desk-based assessment can be built from half-hourly meter data and roof drawings, giving an indicative system size, generation forecast and internal rate of return.

If the numbers work, the next step is normally a structural and electrical survey, after which a proposal with full yield modelling and contract terms can be prepared. A sound proposal is frank about roof condition and grid connection and says so upfront if a site does not suit solar. Send an enquiry and we reply by email.
