UK workers overpay HMRC by thousands every year. We're a specialist tax recovery firm that finds, claims and recovers what's yours — with zero upfront cost.
Indicative only — based on average claim multiples.
If you've paid tax through PAYE or CIS, there's a strong chance HMRC owes you. These are the trades we recover for, every single day.
Self-employed and CIS workers regularly overpay due to complex deductions. We unpick every expense — travel, tools, meals, PPE — and recover what's yours.
Plumbers, electricians, bricklayers, carpenters and beyond. Professional fees, tool purchases and uniform costs add up — and most go unclaimed.
Travel between sites, specialist equipment, height-safety gear and food costs — roofers have one of the highest average rebate values we see.
Constructing and dismantling scaffolding across multiple sites means significant travel and subsistence costs — most are fully reclaimable.
From building sites to road resurfacing, labourers cover personal costs that should rightfully come back. We make sure every penny gets reclaimed.
Van and HGV drivers regularly miss out on substantial refunds for overnight stays, food and uniform — even when working through an employer.
No paperwork mountain. No long phone calls to HMRC. Just a clean, four-step process built by specialists who know how to get results.
Tell us about your work and we'll instantly assess whether you're owed a refund — no commitment, no obligation.
We guide you through exactly what's needed — payslips, expense records, work history — and handle the rest.
Our team prepares and submits your claim directly to HMRC, including every eligible expense and allowance.
Most refunds land within 7 days of HMRC processing. We deduct only an agreed fee — no win, no fee.
From April 2026, HMRC requires four quarterly submissions instead of one annual return. We handle every quarter end-to-end — backed by our TaxSense™ automation platform and a live client portal you can check any time.

Great service, received my rebate in just 6 days. No hassle at all, extremely helpful — would definitely recommend.
I'd been putting off doing my CIS returns for years and getting penalty letters. Maximum Rebate cleared the lot and got me a refund on top.
More and more people are finding out they're owed thousands — just because a friend told them. Refer a mate to Maximum Rebate, and once they make a successful claim, we'll put £50 in your pocket. No limit on how many you can refer.
