CIS payroll for UK construction. Run by specialists.
Scheme setup, monthly verification, CIS300 returns, statements. Handled end-to-end by a team that knows construction. From our London base, we run CIS payroll for construction firms across the UK, from contractors with a handful of subcontractors to major operations with one hundred or more on the books.
We treat CIS as a service in its own right, not an add-on to general bookkeeping. Every step of the lifecycle is covered, from your first subcontractor verification to your year-end reconciliation.
CIS scheme registration with HMRC and software setup
Subcontractor verification (20%, 30% or gross payment status) before first payment
Weekly, fortnightly or monthly CIS processing on the cycle that matches your site invoicing
Monthly CIS300 returns filed on time, including nil returns where applicable
CIS payment and deduction statements issued to subcontractors on a predictable schedule
Gross payment status applications prepared and submitted on behalf of qualifying subcontractors
Mixed PAYE and CIS schemes for businesses with employees and subcontractors in parallel
HMRC correspondence on CIS matters, including reasonable-excuse appeals on late filings
Year-end reconciliation and clean record set ready for accounts
And other CIS-related support on request
WHO THIS IS FOR

Mixed-workforce businesses running CIS for subcontractors and PAYE for direct employees in parallel
Subcontractors operating as their own limited company who engage further subcontractors and need a contractor scheme of their own

Public-sector deemed contractors hitting the £3m rolling spend threshold for the first time
HOW IT WORKS
Our process.
Free conversation
Tell us about your subcontractor base, your site rhythm and your current setup. We will ask a few targeted questions and either give you a clear scope and quote, or tell you what you need to do first.
Written scope and fixed quote
We send a short proposal: what we will do each month, how often, on which software, and exactly what it will cost. Transparent monthly fee, no retainers, no surprises.
Onboarding
We register or take over the CIS scheme, migrate subcontractor records, confirm verification statuses with HMRC, and configure your software. The first full cycle is under our control inside thirty days.
Monthly cycle
Subcontractor invoices in, verification handled, deductions applied at the correct rate, statements issued, CIS300 filed by the 19th. Approval by email, WhatsApp or call. Records kept in your client portal.
COMMON QUESTIONS
FAQs
20% for subcontractors HMRC has verified, 30% for those it has not, and 0% for those with gross payment status. We verify every subcontractor before their first payment so the rate is always correct.
Late filing triggers a £100 penalty after one day, with further penalties at 2, 6 and 12 months. If you have a reasonable excuse, we can submit one on your behalf. The first step is to file the outstanding return and bring the scheme current. We do both as part of onboarding when we take over an inherited scheme.
Yes, and it is common. Direct employees go on PAYE, subcontractors go on CIS, and the two schemes run in parallel under one employer reference. We set this up routinely.
Gross payment status means the contractor pays the subcontractor with no CIS deduction at source. To qualify, HMRC tests compliance, turnover and business structure. We prepare and submit applications for subcontractors that qualify, including yours if you operate through your own limited company.
