Tax Rebates for Plumbers: What You Can Claim Back

Plumbers and heating engineers buy their own tools, wear out their own workwear and travel between jobs, often without ever claiming the tax relief they are entitled to. Whether you are employed or self-employed under CIS, it is well worth checking whether HMRC owes you, because a claim usually covers several years at once. This guide explains what plumbers can claim.

Why plumbers are often owed a rebate

Plumbing involves real, recurring costs you cover yourself, and HMRC allows tax relief on many of them. It does not refund them automatically. Because the costs repeat year after year and you can backdate a claim by four tax years, the totals add up.

What plumbers can claim

Tools and equipment

The cost of buying, repairing and replacing your own tools and equipment can qualify for tax relief, through a flat rate or, for larger purchases, capital allowances. See our tools tax rebate guide.

Travel to temporary sites

If you drive your own vehicle between jobs (not your normal commute) and are paid less than HMRC’s approved rate, you can claim mileage relief on the shortfall.

Uniform and protective clothing

If you maintain your own workwear or protective gear, such as branded clothing and safety boots, and wash or replace it yourself, you can claim the uniform maintenance allowance.

If you work under CIS

If you are a self-employed plumber working under the Construction Industry Scheme, you reclaim overpaid tax through Self Assessment, claiming your tools, travel and other costs as expenses. See our CIS tax rebate guide.

How far back can I claim?

The current tax year plus the previous four. The oldest year drops off each 5 April, so claiming sooner protects an extra year.

Frequently asked questions

Yes. Buying, repairing and replacing your own tools can qualify, via a flat rate or capital allowances for larger spends.

I am self-employed under CIS. How do I claim?

Through your Self Assessment return, claiming your tools, travel and other costs as expenses.

Do I need receipts?

For a flat rate tools claim, often not. For actual costs and capital allowances, keep your receipts.
