Compliance, built in
Krux encodes the UK schemes construction runs on. Rates and thresholds are maintained in one place and kept current each tax year.
Construction Industry Scheme
Automatic 20% (registered), 30% (unregistered) and 0% (gross status) deductions on the labour element only — materials excluded. Monthly CIS300 drafts and subcontractor payment & deduction statements.
PAYE, NI & pensions
Income tax across the 2026/27 bands, employee and employer National Insurance, and pension auto-enrolment on qualifying earnings (8% total: 3% employer, 5% employee).
Card register
Track every worker's CSCS card type and expiry — Green, Blue, Gold, Black, White — with Valid / Expiring / Expired status and alerts 60 days out.
Risk assessments & method statements
Site- and task-specific RAMS with worker sign-off tracking and pre-start briefing checklists, underpinned by the Management of H&S at Work Regs 1999.
Duty holders & F10
Maintain client, principal designer, principal contractor and contractor duty-holder registers, with an automatic F10 notifiability check (>30 days & >20 workers, or >500 person-days).
Incident reporting
Log incidents and auto-classify reportability — deaths, specified injuries, over-7-day injuries, diseases and dangerous occurrences — with the 10- and 15-day HSE deadlines tracked.
Krux supports compliance but does not replace professional advice. Final figures should be cross-checked against HMRC and HSE guidance before use.
