- Commercial vans get 100 percent Annual Investment Allowance up to 1 million pounds.
- New vans bought by limited companies get full expensing right away without any statutory spending ceiling.
- Sole traders must trim claims for private miles.

Capital allowances on vans give UK firms prompt tax relief on work vehicles. Under the Capital Allowances Act 2001, commercial vans qualify as plant and machinery rather than standard passenger road vehicles. That rule sets them apart from cars. Cars are excluded from AIA and instead attract writing-down allowances at rates set by their CO2 emissions under CAA 2001. Vans qualify for full first-year relief whether new or used.
This article explains the three statutory relief routes, how sole traders must apportion mixed-use claims, and how limited companies handle the van benefit-in-kind charge.
HMRC reliefs for new and used vans
The UK tax code provides three primary statutory mechanisms to write off the complete capital purchase cost of a commercial van. Your legal setup and the age of the vehicle decide which path pays best.
| Relief Mechanism | Eligible Entities | First-Year Deduction | Qualifying Vehicle Condition |
|---|---|---|---|
| Annual Investment Allowance (AIA) | Sole traders, partnerships, companies | 100% up to £1,000,000 | New or second-hand vans |
| Full Expensing (CAA 2001 s.45S) | Limited companies only | 100% uncapped | Brand-new and unused only |
| Main Pool Writing-Down Allowance | All business structures | 18% reducing balance | New or second-hand vans |
The Annual Investment Allowance offers up to 1 million pounds of full tax relief each year. It covers both new and second-hand commercial vans. If your firm buys a reliable second-hand van for 18,000 pounds, you can deduct the entire capital outlay in year one. Cars cannot use this relief under the Capital Allowances Act 2001.
Limited firms can claim full expensing under section 45S of the Capital Allowances Act 2001. This relief applies to qualifying expenditure incurred on or after 1 April 2023, and full expensing was made permanent by Finance Act 2024. It gives an uncapped 100 percent deduction on brand-new commercial vans. Second-hand vans do not qualify. Sole traders cannot use full expensing. But the 1 million pound AIA cap covers almost all small trade fleets throughout the United Kingdom.
Exhausted AIA goes to the main pool. That pool writes down at 18 percent each year on a reducing balance basis.
Sole trader rules for private use
Sole traders own their vans directly. If you take a work van on personal weekend errands, you cannot claim the full purchase cost against your taxable trading profits. HMRC requires an accurate split.
Under tax law, a mixed-use van sits inside a single-asset pool. You calculate the full writing-down allowance or Annual Investment Allowance on the initial vehicle invoice, but you deduct only the verified commercial proportion on your SA103 tax return. For general road travel costs, read our guide on HMRC business mileage rules to check standard mileage rates.
Take a simple case. Say a self-employed plumber buys a used van for 20,000 pounds. The plumber drives 15,000 miles in the tax year, recording 12,000 work miles and 3,000 private miles across the accounting period. The business share is 80 percent. Claims must match logs.
| Step in Calculation | Vehicle Figure | Tax Return Treatment |
|---|---|---|
| Total purchase price | £20,000 | Recorded on capital asset register |
| Business mileage share | 80% (12,000 of 15,000 miles) | Evidenced by mileage log |
| Calculated AIA relief (100%) | £20,000 | Single-asset pool baseline |
| Allowable tax deduction | £16,000 | Deducted on SA103 self-employment page |
| Disallowed private portion | £4,000 | Permanent non-deductible expense |
Here, the plumber claims a 16,000 pound deduction against self-employed profit. The remaining 4,000 pounds counts as private use and brings no tax relief. If you also use personal vehicles for work, read our breakdown of capital allowances on cars with private use to compare vehicle rules.
Company van rules and benefit in kind
Limited companies follow a separate legal path. A company buys and owns the van as its own legal person. Since the corporate entity owns the physical asset, it claims the full 100 percent capital deduction on its CT600 corporation tax return. Personal staff driving does not cut that claim. Relief stays complete.
Instead, HMRC taxes private use on the driver through the perks code. When a director uses a company van for private trips, a van perk charge applies. Driving between home and a daily workplace counts as private use under tax law. Commuting is not work.
Under HMRC Employment Income Manual EIM23151, the flat-rate company van benefit charge for the 2024 to 2025 tax year is 3,960 pounds. Paying for private fuel adds another 757 pounds. HMRC reviews both statutory charges each tax year. Insignificant private journeys remain exempt under EIM23151. However, drivers must confirm journey status with an accountant before claiming this relief. Directors should also review trivial benefit rules for directors UK to check exempt minor perks.
Double-cab pickups and vehicle definitions
Vehicle type sets your tax relief. Under the Capital Allowances Act 2001 and HMRC guidance in CA23510, a vehicle is treated as a car unless built chiefly to haul freight. Box vans and car-derived vans pass this test without doubt.
Double-cab pickups demand care. The tax treatment of double-cab pickups has been subject to HMRC policy changes. Always confirm the current HMRC position with an accountant before purchase, as misclassification removes AIA eligibility. When HMRC treats a vehicle as a car, the business loses the 100 percent Annual Investment Allowance. It must then take lower pool write-downs based on emissions.
Check the V5C logbook before you buy. The V5C body-type entry offers an initial guide, but HMRC determines status under CAA 2001 and CA23510 by assessing whether the vehicle is constructed primarily to convey goods. For wider company rules, see our guide on associated company rules UK corporation tax to track small firm thresholds.
Records required for an HMRC review
HMRC checks capital allowance claims with care. Keep proof from the day of purchase until six years after you file.
Hold on to the original dealer invoice showing the date, chassis number, and VAT breakdown. If you are VAT registered, see our guide on VAT annual accounting scheme rules to manage cash flow. Keep the V5C logbook. Sole traders must keep a daily logbook showing trip dates, goals, and mile counts. Incomplete records will fail an HMRC compliance check.
Tax rules on double-cab pickups have changed across recent Finance Acts. Confirm current HMRC classification guidance with a qualified accountant before purchasing.
