Why this sector

Warehousing and logistics presents the largest commercial roof areas in the UK and therefore the largest physical solar capacity per site. The economic case varies more than any other sector because demand profiles vary so much. A modern ambient warehouse running lighting, conveyor, and forklift charging may pull 50–200 kW peak — far less than the 500kWp+ of capacity the roof can hold. A cold-storage facility running compressors 24/7 may pull 800–1500 kW — fully absorbing even a megawatt of solar. EV-integrated logistics hubs are an emerging case: depot charging fleets of HGVs and vans creates significant daytime demand that solar covers economically. Where self-consumption is below 60%, two strategic options open up: PPA structure (where the developer's economics work harder on export) or strategic battery storage (which time-shifts midday surplus to evening and overnight charging). For property-owning REITs with mixed-use logistics portfolios, we typically recommend a blend: capital purchase on owner-occupied buildings, PPA on tenanted multi-let estates, and selective battery deployment where charging integration justifies it.


Electricity profile

Variable by operation: ambient warehousing has modest electricity demand dominated by lighting and material handling; cold storage has heavy 24/7 baseload from refrigeration; logistics hubs with EV fleet charging have growing daytime demand. Self-consumption ranges from 50% (ambient warehouse with limited demand) to 95%+ (cold storage and EV-integrated logistics).

Tax position

Logistics operators typically corporation-tax-paying and able to use FYA. Property-owning logistics REITs and investment vehicles have more complex tax positions and may prefer PPA or operating lease structures, where the FYA is captured by the developer and reflected in lower energy costs.

Pitfalls to watch

  • Tenant/landlord split — many logistics buildings are leased; aligning landlord capital with tenant electricity benefit requires careful structuring
  • Roof load assessments more onerous on lightweight cladding common in modern logistics sheds
  • DNO export limits frequently bite at multi-MW scale — design against zero-export or limited-export from the outset
  • Battery storage and EV charging materially shift the economics — worth modelling integrated solution
  • Triple-net leases may not capture electricity savings for the landlord — PPA may be the only viable structure

Commercial solar for warehousing and logistics — detailed guide

UK distribution and logistics properties offer some of the most compelling commercial solar economics of any sector. Large south-facing roof surfaces, consistent daytime energy demand (conveyor systems, racking, lighting, dock equipment, refrigeration), and strong tax positions produce paybacks of 4–6 years for owned properties. Logistics operators and distribution centre landlords are both significant buyers.

EV fleet charging integration

The logistics sector is undergoing rapid electrification of delivery fleets — Royal Mail, DPD, DHL, and multiple last-mile operators are deploying electric vans and HGVs. This creates a natural synergy with rooftop solar: daytime vehicle charging aligns with peak solar generation, improving self-consumption ratios and reducing the daytime demand peak on the grid connection.

Smart charging and solar integration

Energy Management Systems (EMS) that combine solar monitoring with EV charge scheduling can achieve 40–65% solar-charged vehicle kilometres at urban depots. Vehicles returned during daylight hours and charged at solar peak (11am–3pm) capture the majority of solar generation. Smart chargers (OCPP-compliant, compatible with EMS platforms) are the prerequisite.

Grid connection sizing for combined solar + EV charging

A 500kWp solar installation with 20 × 50kW EV rapid chargers requires a 1MW+ grid connection — significantly larger than a solar-only connection. Plan the combined grid connection early: DNO applications for large connections take 6–18 months. Under-sizing the connection and having to upsize later costs £25,000–£100,000+ in additional DNO reinforcement costs.

Government EV charging grants for logistics

The Workplace Charging Scheme (WCS) provides up to £350/socket for EV charge points (up to 40 sockets per business per financial year). Combined with the capital allowance regime (EV charge points qualify for 100% first-year capital allowances), the effective cost of a 50kW charge point to a 25% corporation tax payer is approximately £5,400 net — compared to £9,000 gross.

Landlord vs occupier solar at logistics properties

Major UK logistics property owners (SEGRO, Prologis, Tritax, LondonMetric, Warehouse REIT) have active sustainability programmes including portfolio solar deployment. The distribution of costs and benefits between landlord and tenant is increasingly governed by "green lease" clauses.

Landlord-funded solar with tenant PPA

The landlord installs the solar, capitalises it on their balance sheet, and sells the electricity to the tenant at a PPA rate (typically 90–95% of grid electricity cost). The tenant benefits from cheaper electricity; the landlord gets a return on capital and a sustainability credential. Standard RICS Green Lease Toolkit clauses now cover this structure. Effective where the tenant has a short lease (preventing the tenant from investing in long-payback capital improvements) or where the landlord has a portfolio solar programme.

Tenant-funded solar (with landlord permission)

For longer leases (15+ years), the tenant can fund the installation independently and claim the FYA. The lease must include a licence to install, fix, and operate solar equipment on the roof, including rights of access for O&M. Removal obligations at lease end (if any) should be agreed upfront — "remove and restore" clauses significantly reduce the project's residual value and IRR.

Frequently asked questions

How big can a warehouse solar system be?
Mega-warehouse rooftops (typically 30,000m²+) support 1-2 MWp solar arrays. The binding constraint is usually DNO export capacity rather than roof area — large warehouse arrays often face G99 reinforcement studies above 500 kWp with potential network upgrade costs. Typical UK warehouse projects land 500 kWp-1.5 MWp.
What's the typical warehouse solar ROI?
For continuous-operation warehouses (cold storage, 24/7 distribution), 14-18% post-tax IRR with strong self-consumption (75-90%). Single-shift warehouses 11-14% IRR. PPA-funded warehouse solar delivers 8-12% IRR but with zero capex risk. Customer-side ESG procurement uplift sometimes adds 2-4 percentage points to project economics for retailer-supplier warehouses.
Do landlord-tenant arrangements complicate warehouse solar?
Yes — but UK PPA structures handle the landlord-tenant split well. Standard arrangement: landlord provides roof access via lease provision, PPA developer installs and owns the system, tenant becomes the electricity offtaker. Landlord receives ground rent from PPA developer. We negotiate landlord-tenant solar provisions on every advisory engagement involving leased warehouses.
Can warehouses combine solar with battery storage?
Yes — increasingly common on large warehouses. Battery storage adds value where: DNO export is constrained (battery absorbs surplus rather than curtailing), time-of-use tariff structure exposes the operation to peak/off-peak spreads, capacity market revenue is accessible (typically 1 MWh+ scale). Combined solar + battery often delivers 1-3 percentage points additional IRR vs solar alone for qualifying sites.
How does warehouse solar interact with EV charging deployment?
Strongly. Warehouses deploying EV charging for fleet electrification find solar a natural complement — generation profile aligns with daytime fleet vehicle return-to-base charging. Combined solar + EV charging often qualifies for additional grant routes and tax allowances. Some 3PL operators are bundling solar + EV + battery as integrated decarbonisation infrastructure.

Commercial solar finance for warehousing and logistics: the 2026 market

UK warehousing and logistics businesses represent some of the best commercial solar opportunities in the country. The economics are compelling: large flat single-storey rooftops with minimal shading, high daytime electricity consumption from forklifts, refrigeration, lighting and conveyor systems, and long lease terms that underpin finance structures. In 2026, there are more than 4GWp of commercial solar installed on UK logistics rooftops, with a further 2GWp in the development pipeline.

The landlord-tenant solar split in UK logistics

The single biggest friction in logistics solar finance is the landlord-tenant split. In most UK logistics parks, the building owner (typically an institutional REIT or specialist logistics developer) and the occupying business are separate entities with potentially conflicting interests. Understanding how each party can fund solar — and which structures allow both sides to benefit — is the key to unlocking logistics solar at scale.

EV charging and solar: the logistics opportunity that changes the payback

Electric forklifts, electric HGVs and last-mile EV vans are transforming electricity demand in UK logistics. A 100,000 sq ft distribution centre that added 50 electric forklifts in 2023–24 has seen its annual electricity consumption increase by 400,000–600,000 kWh. This is precisely the type of load that commercial solar serves best: predictable daytime charging, high volume, and a clear financial case. For a logistics operator funding solar alongside an EV fleet transition, the combined green loan (solar + EV charging infrastructure as a single clean energy asset bundle) is almost always the most cost-effective structure. NatWest, Lloyds and specialist lenders Propel and Solar Finance UK will now underwrite combined solar+EV bundles on a single loan.

MEES compliance and logistics solar: the looming 2030 deadline

The proposed expansion of MEES (Minimum Energy Efficiency Standards) to commercial property from 2030 means that logistics buildings currently rated EPC C or below face a compliance deadline. Commercial solar PV has a direct impact on EPC rating — particularly for buildings where the grid electricity import drives the rating down. A well-sized solar system on a logistics building can typically improve EPC rating by one to two bands. For institutional landlords managing large logistics portfolios, this creates a strong financial case for programme-level solar deployment ahead of the 2030 deadline — and for tenants approaching lease renewal, the solar finance conversation is increasingly linked to the MEES conversation.
