CF Contractor
Trusted Payroll. Robust Compliance. Contractor Focused.
CF Contractor is a specialist UK provider of Umbrella PAYE and CIS payroll solutions, supporting contractors, recruitment agencies and businesses across the UK.
Our approach is built around three fundamental principles: compliance, transparency and reliability. We recognise that recruitment businesses need more than a payroll provider; they need a trusted supply-chain partner capable of protecting their reputation, supporting their contractors and consistently delivering to the highest professional standards.
Whether working with an independent recruitment consultancy, a national agency or a complex MSP supply chain, CF Contractor provides a responsive and straightforward service tailored to the requirements of each client.
Our objective is simple: make contractor payroll secure, compliant and dependable.
We combine robust processes with a highly personal service, ensuring contractors are paid accurately and on time while providing our recruitment partners with the confidence that their workforce is being managed responsibly.
Compliance at the Core
Compliance is fundamental to everything we do.
The contractor payroll landscape continues to evolve, placing increasing responsibility on recruitment agencies and end clients to understand and manage risk throughout their labour supply chains.
CF Contractor is committed to operating to the highest standards of UK tax, employment and payroll compliance.
Our systems, procedures and controls are designed to provide transparency throughout the payroll process, giving recruitment partners greater confidence in the integrity of their contractor supply chain.
We believe compliance should be visible, demonstrable and verifiable — not simply promised.
By combining rigorous operational controls with clear communication and transparent processes, CF Contractor helps agencies minimise payroll risk while maintaining a professional and dependable experience for their contractors.
Why CF Contractor?
Experienced Industry Leadership Our team brings extensive experience across contractor payroll, recruitment and workforce management, providing clients with practical expertise and a thorough understanding of the challenges faced by modern recruitment businesses.
Responsive Support Recruitment does not always operate within conventional office hours. Our service model is therefore designed around accessibility and responsiveness, ensuring agencies and contractors can obtain support when they need it.
Umbrella PAYE & CIS Solutions We provide specialist Umbrella PAYE and CIS payroll services designed around the requirements of temporary, contract and contingent workforces.
Accurate & Dependable Payroll Getting people paid correctly and on time is fundamental. Our payroll processes are designed around accuracy, consistency and reliability, helping agencies maintain strong relationships with their contractors.
Compliance-Led Approach We place compliance at the centre of our business. Robust procedures and transparent processes help protect contractors, recruitment agencies and end clients throughout the supply chain.
Partnership Mentality We don’t believe in being a faceless payroll provider. CF Contractor works alongside its recruitment partners, understanding their businesses and providing a service that complements their own contractor proposition.
Protecting Your Contractors. Protecting Your Business.
The relationship between an agency and its contractors is valuable.
CF Contractor understands that every interaction we have with a contractor reflects upon the recruitment agency that introduced them to us. We therefore place considerable emphasis on service quality, communication and professionalism.
From onboarding through to payroll and ongoing support, our aim is to make the process straightforward for contractors while giving agencies confidence that their workers are being looked after properly.
For our recruitment partners, that means a payroll provider focused not only on processing payments, but on protecting relationships, strengthening compliance and supporting the long-term reputation of their business.
