Payroll Outsourcing Services UK

Make sure your UK employees are paid correctly and on time — every time — with our UK payroll services.

UK tax codes, laws and rules are changing more rapidly than ever before: from a statutory point of view, PAYE payroll has changed more over the past five years than it has in the last 20 years. Over the years, the payroll function has also become increasingly complicated — from managing pension auto-enrolment to furlough (something many businesses had never even heard of before the pandemic). So, the question isn’t should I outsource my UK payroll? The question is: who should I outsource it to?

What our UK payroll clients say

“I came across TopSource because I’ve used them previously, at three different businesses”.

“Simply put, they know their stuff. They are personable guys who are flexible and knowledgeable. We recently completed a migration in very short order, and I do not think anyone in the finance or HR departments believed it could be done as smoothly as it was. Much of that credit goes to TopSource”.


“I first came across TopSource 10 years ago when I was working at Peyton & Byrne. I then brought them in at a later role at Focus Hotels because I wanted to improve our processes”.

Admiralty Arch

“I believe there were three companies in the running; the decision was made partly because of price, but the main factor was that the head of HR had worked with TS as an outsourced payroll provider at a previous company. So, there was that recommendation and peace of mind”.

Eco World London Development

“Very few companies can do time-related payroll with high volume, and TopSource do it well. I believe there are very few competitors to TopSource based on the volume of my work and complexity of my payroll”.

Quadrant Recruitment

“In the early stages of the business, our business had outsourced our financial director role to an accountancy firm, and that firm recommended TopSource to us”.


“I am a career finance person and, consequently, I have come across countless examples of businesses that are looking to outsource payroll. For the last 12 years, TopSource has been my go-to recommendation for that service. I came across TopSource because I have used them previously, at three different businesses”.
