CIS and VAT basics for construction recruitment agencies
Practical CIS deduction and VAT points for agencies placing contractors in UK construction.
Construction placements add compliance layers
Agencies placing contractors into construction face CIS deduction rules alongside ordinary payroll, umbrella and VAT questions. Treating construction like office contracting creates under-deduction risk or candidate disputes when payslips do not match the verbal offer made on site.
Process and education matter as much as software. A clever payroll system still fails if booking teams enter the wrong status at the start.
Get the status and deduction trail clear
Know when CIS applies, what rate is used and how statements reach contractors. Keep records that reconcile to payroll and to client invoices. VAT on agency services still needs correct treatment even when CIS sits on the labour chain and everyone is focused on the deduction percentage.
Train booking teams so compliance is not only a back-office repair function. Wrong bookings are expensive to unwind after timesheets have already been approved.
Show candidates the net earlier
Construction contractors compare net pay aggressively. Agencies that explain CIS, umbrella margins and limited company routes with clear figures win trust and reduce dropouts after the first payslip lands short of expectations.
CIS-aware accounts help directors see whether construction desks are contributing after compliance cost, not only after gross billings.
Making finance useful on the sales floor
Give consultants a one-page view of contribution by desk and a short take-home comparison they are allowed to share. Pair that with the IR35 or CIS checklist so compliance is part of the placement conversation, not a later correction. Review debtor days alongside billings so volume targets do not hide collection risk. Agencies that let finance teach the floor in plain English lose fewer candidates to payslip surprises and fewer placements to avoidable status disputes.
A note on timing
Do the unglamorous work in quiet months: tidy records, agree policies, and book the mid-year review before winter pressure or year-end deadlines arrive. Most expensive accountancy problems started as postponed admin. A ninety-minute planning call in summer often prevents a frantic March. Build the habit even when nothing feels urgent, because urgency is usually a sign the calendar was empty of planning.
