Grants and funding for cold storage
Capital allowances, tax relief and the compliance drivers that pay for efficient plant. Updated for 2026.
Unlike domestic renewables, cold storage has no headline grant scheme — the funding case rests on capital allowances and the hard economics of the F-gas phase-down. That is good news for a limited company: refrigeration plant and cold room panels qualify as plant and machinery, so most of the capital cost can be written off against tax in year one. Below is each route that genuinely applies.
Important: the Industrial Energy Transformation Fund (IETF), which historically funded refrigeration and cold-chain efficiency at 30-50 per cent intervention, is closed to new applications following the July 2025 Spending Review, and no further competition windows are planned. Previously awarded projects remain funded. Older references may still present it as open, so check gov.uk before relying on it.
Funding routes for cold storage
Capital Allowances (100% Annual Investment Allowance)
Refrigeration plant, cold room panels and associated works qualify as plant and machinery for UK businesses. The Annual Investment Allowance gives 100 per cent first-year relief on up to £1m of qualifying capex.
- Value
- Up to 100 per cent of qualifying capex written off in year one, an effective saving of up to 25 per cent of spend for a limited company.
Most cold room and mid-size cold store projects fall fully within the £1m AIA. This is the primary funding lever for cold-chain capex.
Full Expensing (companies, main-rate plant)
Companies subject to corporation tax can claim 100 per cent first-year relief on qualifying new main-rate plant and machinery, with no annual cap, above the AIA limit.
- Value
- 100 per cent first-year deduction on qualifying new main-rate plant, for spending from 1 April 2023.
Relevant for larger refrigerated warehouse and CA-store builds where capex exceeds the £1m AIA. New (not used) plant only.
Industrial Energy Transformation Fund (IETF)
DESNZ grant for energy-efficiency and deep-decarbonisation projects at industrial sites, which included refrigeration and cold-chain efficiency measures. Following the 2025 Spending Review the IETF is closed to new applications and no further competition windows are planned; previously awarded projects remain funded.
- Value
- Historically 30 to 50 per cent intervention on eligible capex; now closed to new bids.
Not open for new cold-store applications as of 2026. Watch for any successor industrial-decarbonisation scheme and check gov.uk before relying on it.
F-gas-driven refrigerant upgrade (via capital allowances)
There is no dedicated grant for replacing HFC plant, but the tightening GB F-gas quota makes upgrading to CO2, R290 or ammonia plant increasingly compelling, and that new plant is claimable under AIA or full expensing (companies only, for new main-rate plant).
- Value
- Tax relief on the plant plus avoided future HFC-scarcity and service costs.
Treat this as a compliance-and-efficiency driver rather than a grant. The phase-down toward a 79 per cent HFC cut by 2030 is the trigger.
Smart Export Guarantee (SEG) via solar offset
Not a cold-storage grant. Where on-site solar is added to offset the refrigeration load, any surplus export is paid under SEG (MCS-registered solar installs up to 5 MW).
- Value
- Roughly 4 to 15p per kWh exported as of 2026.
For 24/7 refrigeration, self-consumption dominates and export is minimal, so SEG is a small secondary benefit. For solar sizing, get a separate solar quote.
How they stack
For most projects the Annual Investment Allowance covers the whole capex within its £1m limit, so a single cold room or mid-size store is fully relieved in year one. Larger refrigerated warehouse and controlled-atmosphere builds that exceed £1m use Full Expensing (companies only, for new main-rate plant) on the balance. The F-gas quota is not a funding route in itself, but it is the reason to act: legacy R404A and R410A plant is getting scarcer and dearer to service, so replacing it with CO2, R290 or ammonia plant — claimed under capital allowances — is both a compliance move and an efficiency gain of around 19 per cent. Where on-site solar is added to offset the 24/7 load, any surplus export is paid under the Smart Export Guarantee, though for constant refrigeration demand self-consumption dominates and export is minimal; a solar array is a separate purchase with its own quote. Confirm the treatment of any allowance with your accountant.
