Everything a UK contractor needs
One platform from the site fence to the pay run — no spreadsheets, no missed certs, no compliance surprises.
GPS timesheets
Workers clock in from the field. Krux flags clock-ins away from site and anomalies before they hit payroll.
CIS + PAYE payroll
Automatic 20%/30%/0% CIS deductions, PAYE tax, NI and pension auto-enrolment — gross to net in one run.
CSCS card tracking
Every worker's card type and expiry tracked, with alerts before anyone turns up to site with an expired card.
RAMS & CDM 2015
Method-statement sign-off, duty-holder registers and an F10 notifiability check built in.
RIDDOR reporting
Log incidents, auto-classify reportability and never miss a 10- or 15-day HSE deadline.
Multi-site control
Live progress, budgets and crew across every site — for owners and managers alike.
UK rules, encoded — not bolted on.
Krux is built around the schemes UK construction actually runs on. Rates and thresholds are kept current for the tax year, in one place.
