Mobile Dog Groomer & Pet Services Tax UK 2026/27

A Trade Built on Vehicle and Equipment Costs

Mobile dog grooming is unusual among self-employed trades because a large share of the start-up cost sits in a single asset: the grooming van itself, typically converted with a water tank, heated dryer, bathing tub and grooming table. Fixed-premises groomers face a different cost profile — salon or unit rent plus fitting-out costs — but the underlying tax treatment as a self-employed trader is the same either way.

Most independent groomers, whether mobile or salon-based, are sole traders: they set their own prices, choose their own client list, and bear the financial risk if a booking cancels last minute. That self-employed status is what allows the wide range of vehicle, equipment and product expenses discussed below to be claimed against income tax.

Capital Allowances on the Grooming Van

Because a converted grooming van is expensive — often £20,000-£40,000 once fitted out — it's usually treated as a capital asset rather than a simple running expense. Sole traders can typically claim the Annual Investment Allowance, which lets you deduct the full qualifying cost of plant and machinery (including a business van and its fit-out) from profits in the year of purchase, up to the AIA's generous annual limit. This is one of the most valuable reliefs available to a new mobile groomer, since it can turn a large first-year capital outlay into an immediate and substantial reduction in taxable profit.

Running Costs: Actual Costs or Mileage Rate

For day-to-day running costs, self-employed groomers choose between two methods:

• Simplified mileage rate: 45p per mile for the first 10,000 business miles each tax year, then 25p per mile after that — this single rate covers fuel, insurance, servicing, wear and depreciation.
• Actual costs method: claiming a proportion of real fuel, insurance, servicing, repairs and finance costs, adjusted for any private use, alongside a separate capital allowance claim for the vehicle.

You must pick one method for a given vehicle and stick with it consistently — you cannot claim mileage and actual fuel receipts for the same van in the same period. For a heavily converted grooming van with a large capital allowance claim already taken, the actual-costs method is often more advantageous than the flat mileage rate.

Products, Tools and Insurance

Beyond the van, ongoing allowable expenses include shampoos and conditioners, clipper blades and their sharpening, dryers, grooming tables, and generator or water costs for a mobile set-up. Public liability insurance — covering the real risk of an animal injury, a bite, or property damage during a groom — is a near-universal and fully deductible cost in this trade, alongside any professional grooming body membership.

VAT and National Insurance

Individual mobile groomers, even busy ones charging £30-£60 per dog across a full working week, rarely approach the £90,000 VAT registration threshold on their own. It becomes more relevant for grooming businesses that scale to multiple vans and employed staff. Self-employed groomers pay Class 4 National Insurance at 6% on profits between £12,570 and £50,270, and 2% above that, in addition to income tax, with Class 2 effectively abolished above the £7,105 small profits threshold.
