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.

Sector-specific funding
No sector-specific grants. UK Infrastructure Bank funding available for very large logistics decarbonisation projects (>£10m). Some local authority commercial decarbonisation grants for warehouses in specific zones.
Worked example
Regional distribution centre, M1 corridor. 45,000m² composite roof with 1.2MWp PV and integrated 80-bay HGV electric depot charging.
£1,050,000 PV + £620,000 depot charging
£245,000 year-one (combined PV self-consumption and avoided wholesale on charging)
5.1 years on PV alone; 4.6 years combined PV+charging
Capital purchase from operating cash. FYA + AIA fully utilised.
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.
Warehouse types and solar potential
| Warehouse category | Typical roof area | System size range | Electricity profile | Solar self-consumption |
|---|---|---|---|---|
| Multi-temperature DC (3PL) | 5,000–20,000m² | 500kWp–2MWp | High baseload from refrigeration; 24/7 demand | 40–55% (night-time refrigeration load lowers daytime ratio) |
| Ambient distribution centre | 5,000–30,000m² | 500kWp–3MWp | Operational hours-driven; conveyors, lighting, charging | 65–80% with EV/forklift demand management |
| Urban last-mile depot (<5,000m²) | 500–2,500m² | 50kWp–250kWp | Vehicle charging dominant; peaked morning dispatch | 55–70% depending on charging schedule |
| Bonded / port-adjacent warehouse | 2,000–8,000m² | 200kWp–800kWp | Variable — handling equipment dominant | 60–75% |
| Cold store / frozen food (-25°C) | 1,000–5,000m² | 100kWp–500kWp | Extremely high 24/7 refrigeration load; 0.5–1.5kW/m² facility | 30–45% — battery storage significantly improves |
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.

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.
Solar finance for logistics: the unique characteristics
| Factor | What it means for solar finance | Optimal finance structure |
|---|---|---|
| Large flat rooftops (5,000–100,000 m²) | System sizes 500kWp–10MWp; below £1/Wp cost at scale; strong project economics | Capital purchase with AIA on first £1m; green loan for balance; PPA viable at 5MWp+ |
| High daytime electricity consumption | Self-consumption rate 70–95%; minimal export; very fast payback | Capital purchase with AIA; or green loan where tenant wants ownership without capex |
| Tenant-occupied logistics buildings | Landlord may own building; tenant may want solar | Tenant-funded: green loan or HP with landlord consent; Landlord-funded: PPA with tenant energy offtake |
| Long lease terms (10–25 years standard) | Lease term exceeds finance term; strong asset security for lenders | Most finance routes viable; green loan LTV strongest on long leaseholds |
| EV fleet charging integration | DC charger demand during business hours aligns perfectly with solar generation | Bundle solar + EV charging infrastructure in single green loan for optimal economics |
| Cold storage and refrigeration (food logistics) | 24/7 energy consumption; refrigeration load 40–60% of site total | Battery storage + solar bundle captures night-time load; PPA provides price certainty on fridge load |
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.
| Structure | Who funds | Who benefits | Finance type | How it works in practice |
|---|---|---|---|---|
| Tenant self-fund (capital purchase or green loan) | Tenant | Tenant (energy saving; AIA tax relief; SEG) | Green loan or HP secured on solar asset | Tenant applies for green loan; landlord consent required via licence to alter; tenant owns system for lease term; decommissioning or transfer at lease end negotiated |
| Landlord-funded PPA | Landlord (or third-party developer) | Tenant (below-market energy rate); Landlord (rental income on roof; ESG certification) | PPA developer funds installation; landlord signs roof lease; tenant signs PPA | Developer installs system; landlord receives roof lease income; tenant buys power at 8–14p/kWh (vs 35p+ grid rate) |
| Head lease solar clause | Landlord builds solar into lease structure | Both parties | Lease amendment with solar clause | New leases increasingly include solar clause requiring occupier to accept landlord-installed solar; all energy savings shared via bespoke split agreed at lease negotiation |
| REIT portfolio programme | Institutional landlord | Landlord (ESG; MEES compliance; long-term asset value) | Corporate green bond or sustainability-linked loan | Large logistics REITs (Tritax, SEGRO, Prologis, LondonMetric) fund portfolio solar programmes; occupier benefits from below-grid PPA rate for duration of lease |
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.
Finance benchmarks for logistics solar in 2026
| Warehouse size | Suitable system size | Typical installed cost | Annual energy saving | Simple payback | Best finance route |
|---|---|---|---|---|---|
| Small (10,000–25,000 sq ft) | 100–250kWp | £70,000–£250,000 | £16,000–£50,000/yr | 4–7 years | Green loan or hire purchase; AIA in year one |
| Medium (25,000–75,000 sq ft) | 250kWp–750kWp | £200,000–£700,000 | £50,000–£150,000/yr | 4–6 years | Green loan; PPA viable at 500kWp+ |
| Large (75,000–150,000 sq ft) | 750kWp–1.5MWp | £650,000–£1.2m | £150,000–£280,000/yr | 4–5 years | AIA on first £1m + green loan for balance; PPA at scale |
| Mega-shed (150,000+ sq ft) | 1.5MWp–5MWp+ | £1.2m–£3.5m | £280,000–£700,000/yr | 3.5–5 years | Developer PPA or corporate green bond; institutional procurement preferred |
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.
