Award winning, forward thinking payroll provider, putting workers first at all times

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.
We are an established payroll intermediary operating low-risk and compliant options for workers engaged through recruitment agencies.
Our story has been created over 15 years by being fluid and adapting to various legislation and labour market changes, gaining accreditations and business awards, coping with economic shifts, navigating a pandemic and the new normal. Always evolving. We think we have some good things to talk about, some standard that you will have heard of and a few innovations that you might not have. We’d love to hear your story and to see if we can help you along the way.
