We believe contractors should be supported and rewarded throughout their careers.

Businesses across the UK rely on skilled contractors every day – bringing specialist expertise, experience and fresh thinking into their teams, often exactly when they need it most.

We have enormous respect for the professionals who choose to work this way and believe they deserve an umbrella company that recognises the contribution they make.

That's why we've been supporting contractors across the UK since 2003. More than two decades and 130,000 contractors later, our principles remain the same: to make umbrella employment straightforward, transparent and supportive, so you can concentrate on doing what you do best.

When operating through your own limited company isn't an option, choosing the right umbrella company matters. As a Key Portfolio employee, you benefit from the protections and rights that come with employment, together with the support of an experienced team that understands the contractor market.

We're FCSA Accredited and SafeRec Certified, providing additional independent reassurance over the standards behind our service and the way your pay is processed.

But for us, being a good umbrella company is about more than processing payroll. It's about valuing you as an employee, being there when you need us and making sure you always have someone to turn to when you have a question about your pay or employment.

After all, we've been looking after contractors since 2003 – and we're very proud that more than 130,000 of them have trusted us to do just that.

NumberMill knows more than most how important payroll and related compliance is to the sector. More than ever and with the introduction of the Criminal Finance Act September 2017, it is even more important for agencies to have the reassurance that their partners meet high standards of compliance and eliminate risk in the supply chain. NumberMill truly has the qualifications, skills, and expertise to keep both contractors and agencies compliant whilst being agile, offering the best commercial, honest & transparent advice, in a constantly changing legislative environment.
