Grimsby and the South Humber bank have become a hub for offshore wind and energy, and that has changed the work on the ground. The renewables and port-related construction, the food-processing estates that keep refreshing their premises, and the town-centre and housing renewal across DN31 to DN37 keep scaffolders, groundworkers, cladders and finishers busy — with industrial and maintenance shutdowns adding seasonal peaks. CIS still takes its cut first, though: 20% (or 30% unverified) off every payment, so most Grimsby trades are owed a refund by the year end.
We handle CIS in full for Grimsby trades: same-day refund filing, monthly CIS300 returns, verification, gross payment status applications, and a Self-Assessment that captures every allowable cost. Fixed monthly fee, filed from 6 April so the refund lands early.
💡 As an HMRC-registered agent, we deal with HMRC directly on your behalf — filing monthly returns, processing refund claims and handling verifications. Same-day filing available from 6 April for the fastest refund.
What We Handle
Self-Assessment filed within 24–48 hours of 6 April with every legitimate expense captured. HMRC refunds typically arrive 4–6 weeks later.
Full monthly CIS300 returns filed direct to HMRC for Grimsby contractors paying subcontractors. Verification handled, deduction statements produced, late-filing penalties avoided.
We verify your subcontractors with HMRC before you pay them, so the correct rate — gross, 20% or 30% — is applied from the very first payment.
For established Grimsby subcontractors who pass the turnover, compliance and business tests, we prepare and submit gross payment status applications so you are paid without deduction.
A simple phone app logs tools, fuel, materials, PPE and CSCS renewals as you go — so nothing is lost and nothing is a scramble next April.
Behind on Self-Assessment or CIS returns? We bring you current and put your case to HMRC, asking for penalty reductions where there is a reasonable excuse.
Refund claims can be made for up to four previous tax years. Plenty of Grimsby subcontractors are sitting on several years' worth without realising it. Book a free call and we'll scope out exactly what's recoverable.

Take a self-employed scaffolder on industrial and port maintenance plus housing jobs across the area. He invoices about £39,000 gross, with roughly £7,800 deducted under CIS before he is paid.
Captured properly: mileage between yards, the port and sites, replacement boards and fittings, harness and PPE, his CISRS card and an offshore-relevant refresher, work clothing, consumables he bought himself, and the business share of his phone and van. Against £7,800 of deductions that base routinely returns a strong four-figure refund, filed in April.
This is an illustrative example to show how a claim is built — your own figures depend entirely on your earnings, deductions and expenses, and we confirm them with you before anything is filed.
