QPS Group are one of the only umbrella companies to offer full salary contracts, giving contractors stronger financial security and peace of mind. Unlike the usual minimum wage plus commission model, your full pay is guaranteed - meaning maternity, paternity and sick pay are based on your real earnings, not minimum wage. This also boosts your chances with mortgages, loans and insurance policies that rely on proof of stable income. Alongside this, QPS provide full FCSA and SafeRec compliance, plus access to perks and rewards - making sure you’re protected, supported and set up for the future.

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.
