Accountant for Plumbers, UK
Based in Stanmore and working online with plumbers and heating engineers in Enfield and right across the UK, we reclaim your overpaid CIS tax and make sure every van, tool and material cost is claimed. Plumbers and heating engineers carry serious costs: a van, fuel between jobs, tools and test equipment, materials you often pay for before the customer settles up, Gas Safe registration, public liability insurance and workwear. If you work on CIS, 20% is taken off your pay at source, and once all those costs are claimed you are usually owed a chunk of it back. Self-filed returns rarely capture the full picture, so the refund is smaller than it should be.
Your Tax Help Accountants works with plumbers, gas engineers and heating engineers across the UK. We reclaim your overpaid CIS tax, claim your van and mileage, tools and test kit, materials, Gas Safe and insurance costs and the business use of your phone, and file an accurate Self Assessment or company return. One fixed fee, one accountant who understands the trade, and your refund chased and paid.
Bought materials for a job and waited to be paid? Drove between three jobs in a day? Renewed your Gas Safe registration? Those are all deductible, along with your van, tools, insurance and mileage at 45p (55p for 2026/27) a mile. We make sure none of it is missed.
What We Handle
On CIS, 20% is deducted before you see your pay. We file your return with every cost claimed and reclaim the overpaid tax, with most plumbers due a healthy refund each year.
Your annual return prepared and filed accurately, your CIS deductions offset, your expenses captured and your refund or bill explained in advance, no January panic.
Every allowable cost claimed: van running costs or mileage, fuel, tools and test equipment, materials, Gas Safe registration, workwear and the business use of your phone.
Growing or going limited? We set up your company, run it tax-efficiently, and help you apply for CIS gross payment status so tax is no longer deducted at source.
Once you pass £90,000 turnover we handle your VAT, including the construction Domestic Reverse Charge, so your invoices and returns are right.
Behind on returns and missing refunds? We bring you fully up to date, reclaim what is owed and handle any HMRC penalties.
If you are a plumber on CIS and you have either never filed or filed a bare return, there is a strong chance HMRC is holding hundreds or thousands of pounds of your money. CIS refunds can usually be claimed for several past years. We review your deductions and your real costs, file or amend the returns, and chase your refund through to your bank account.
Recent Client Outcome
A self-employed heating engineer on CIS had been filing his own returns and getting a modest refund each year. He declared his income and CIS deductions but claimed only his fuel, assuming that was most of it. His refund never felt like it reflected how much the work actually cost him to do.
We went through a full year properly: his van running costs and mileage between jobs, his tools and test equipment, materials he had bought ahead of being paid, his Gas Safe registration, public liability insurance, workwear and the business use of his phone. We corrected the prior year that was still in the amendment window too.
With his genuine expenses set against his income and CIS deductions, his refund came back substantially larger. He now sends his figures once a year for a fixed fee and his refund lands without him chasing HMRC.
