Sign, submit, get paid
You file your own claim and the refund lands in your account, usually within 3–6 weeks. We only charge once it's confirmed.
What counts as an expense
The everyday costs of being on the tools come off your taxable profit. Most lads never claim half of them — that's where your refund hides.
- Van & fuel
- Tools & equipment
- Work boots & PPE
- Phone & internet
- Mileage to sites
- Materials you fronted
- Workwear & washing it
- Use of home as office
One flat fee. Never a cut of your refund.
No-win, no-fee. We only charge once HMRC confirms your refund — and only if it's worth more than the fee. Checking your estimate is always free.
