CIS Accounting Services UK businesses in construction rely on us for, because the rules here are different from any other industry. The construction industry has unique accounting requirements, particularly around the Construction Industry Scheme (CIS). We support contractors and subcontractors with CIS registration, deductions, and monthly returns submitted correctly and on time to HMRC.

We manage bookkeeping, payroll, and project-based accounting to ensure accurate cost tracking and profitability analysis across every contract you run. Our bookkeeping service keeps your job costing and supplier invoices reconciled, so you always know which contracts are actually making money and which are quietly losing it.

Cashflow management is critical in construction, where payment cycles are long and retentions can tie up cash for months at a time. We help businesses forecast cashflow, manage payment cycles, and reduce the financial pressure caused by delayed payments from main contractors. If you employ site staff directly, our payroll service handles CIS deductions, PAYE, and pension auto-enrolment alongside your subcontractor payments, so nothing falls through the cracks.

Our tax and compliance services ensure all filings are accurate and submitted on time, including monthly CIS returns, VAT (including the domestic reverse charge for construction services), and your annual accounts and Companies House filings, allowing construction businesses to operate with confidence rather than scrambling before deadlines.

Most construction accounting problems come down to timing rather than the numbers themselves. A subcontractor verification done late, a CIS deduction statement that does not match HMRC’s records, or a retention that is never invoiced because nobody tracked it: these are the things that quietly erode profit on otherwise successful contracts. We build systems that catch these issues before they become a problem, not after the job is finished and the money is gone.

Whether you are a sole trader subcontractor, a growing contractor business, or a main contractor managing multiple subcontractors and their CIS deductions, our CIS accounting services UK clients rely on us to scale with you. We verify subcontractors, calculate and report CIS deductions correctly, and make sure your monthly returns go in on time, every time, so you never face an unexpected HMRC penalty.

We work across the full range of construction trades, from groundworks and electrical contractors to plumbing, roofing, scaffolding, and specialist subcontractors. Whatever your CIS verification status, gross or net, our CIS accounting services UK contractors and subcontractors depend on adapts to fit.

We also keep an eye on Making Tax Digital requirements as they extend across more of the tax system, so your bookkeeping stays compliant well beyond this tax year. For main contractors managing a long list of subcontractors, we can take over subcontractor verification and CIS deduction statements entirely, freeing up time you would otherwise spend chasing paperwork on site. The result is fewer surprises at year end, fewer HMRC queries, and a clearer picture of profitability on every project you take on.

If you are unsure whether a payment should be treated as CIS-deductible or simply a standard supplier invoice, that is exactly the kind of question we deal with daily, and getting it wrong in either direction can create real problems with HMRC later on.
