NASA Group is a specialist umbrella supplier based in Bristol, working exclusively within the contracting industry nationwide.
As well as being one of the most cost-effective in the industry, we pride ourselves on offering far greater value for our agency partners thanks to the unique way in which we collaborate with them. Rather than a typical ‘one-size-fits-all’ solution, we always ensure that our process is perfectly aligned with theirs so that the entire operation is as efficient as it can be. This benefits everyone in the supply chain including the recruitment agency, by enabling them to spend more time recruiting rather than payroll processing and problem-solving. It also allows the contractor to work more effectively as they fully understand the process and have far fewer questions or concerns. NASA Group goes above and beyond their duty as an employer.
This commitment continues throughout the entire agency relationship as we remain at the forefront of compliance and industry updates. Training agency staff on solutions and legislation is all part of the service, plus NASA Group will assist your business in preparing for legislative changes affecting your sector too. This helps to create a partnership far more valuable than a typical umbrella supplier.
We are always on hand to discuss how we can assist you, plus with regional account managers throughout the UK, we would be glad to talk in person too.

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.

We exist to Create a Legacy that Values All People and Creates Opportunities for Generations to Come - joining Arch will support this mission.
