Tools as a Tax Deduction — What Self-Employed Tradespeople Can Claim

Tools are one of the clearest legitimate business expenses for self-employed tradespeople. If you buy it for work, you can claim it. But the mechanics of how you claim depend on what you bought and how much it cost — and getting that right means more money back.

The basic rule Any tool bought wholly and exclusively for use in your trade is an allowable business expense. That covers hand tools, power tools, testing equipment, safety equipment and consumables.

Keep the receipts. HMRC don't see them on a routine Self Assessment filing but you need them if you're ever queried.

Small tools — straight to expenses

Small tools — anything you'd use up or replace within a few years — are generally treated as a straightforward business expense. You buy them, you claim them in the year of purchase, they reduce your taxable profit.

Examples: Screwdrivers, pliers, spanners, chisels Drill bits, saw blades, abrasive discs — consumables Multimeters, voltage testers, pipe testers Torch, knife, tape measures Tool bags and belts

The honest truth is there's no fixed value threshold that defines "small tools" in HMRC guidance — it's more about whether the item is a long-life capital asset or a working tool. For most hand tools and small power tools, treat them as an expense.

Larger tools and equipment — capital allowances

For more expensive items — a high-end drill, a circular saw, a level station, a generator — HMRC technically treats these as capital assets rather than expenses. This means they go through capital allowances rather than being deducted directly.

In practice, for most sole traders, this makes no difference in the year of purchase because of the Annual Investment Allowance (AIA). The AIA allows you to deduct the full cost of qualifying plant and equipment in the year you buy it — the limit is currently £1 million, which is irrelevant for most individuals.

So whether it's a £50 angle grinder or a £3,000 laser level, you can deduct the full cost in year one.

Tool insurance

Tool insurance premiums are a separate claimable expense — not the same as the tools themselves. If you pay for specialist tools insurance or have tools covered under a combined trades policy, the premium is allowable.

Tool storage

Tool storage on the van — drawers, racking, toolboxes — is claimable. Toolboxes for site storage are claimable. The cost of locking your van or fitting security measures to protect tools is claimable.

Hired tools and plant

If you hire equipment for a specific job — scaffold, a power floater, specialist cutting equipment — the hire cost is a direct business expense for that job. Claim it in full.

Tools with personal use

If a tool is used both professionally and personally — unusual for most trade tools, but possible — you can only claim the business proportion. In practice, most trade tools live on the van and are genuinely work-only. For anything that regularly goes home and is used for personal projects, be sensible about the claim.

Replacing tools that are stolen

If your tools are stolen from the van and you make an insurance claim, the insurance payout is income for tax purposes and the replacement cost is an expense. They broadly cancel out. If you're not insured and buy replacements out of pocket, the replacement cost is claimable.

Keeping records

For each tool purchase: Keep the receipt or invoice Note what it was for if it's not obvious from the description Store receipts digitally — a photo is fine

Dayrates lets you photograph receipts and attach them to jobs from site. At year end, your accountant has everything they need without you reconstructing six months of Screwfix receipts from your jeans pockets.

The practical summary Buy what you need for the job. Keep the receipts. Claim everything. For most trade tools, the full cost comes off your taxable profit in the year of purchase. It's one of the most straightforward areas of self-employed tax — take full advantage of it.
