The Biggest and Best Recruitment Agencies in the UK

best recruitment agencies




All businesses want to work with the best recruitment agencies. But they are spoilt for choice.


The number of recruitment agencies in the UK currently sits at a record high of more than 27,700. This marks a three-fold increase since 2012. With every single agency promising to ‘build a relationship’ with you and ‘work hard for your businesses success’ who can you actually trust with your job vacancy? Who really are the best recruitment agencies in the UK?


More often than not, your safest bet is to go with an agency with big list of existing clients and years of experience under their belt. After all, these agencies work tirelessly to uphold a solid reputation in a fiercely competitive industry. Their clients return to them again and again because they can be trusted to get the job done right first time round.


Yes, you can save money on recruitment fees by partnering with a relatively new agency. But are you willing to take that risk? The explosive growth of the recruitment industry has given rise to a lot of fly-by-night agencies who view recruitment as a get rich quick scheme. They often show no regard for industry best practices and their clients inevitably suffer as a result.


To prevent you from being stung by one of these subpar agencies we have compiled a list of the 5 biggest and best recruitment agencies in the UK. Obviously there are many more great agencies worthy of place on the list, but for the purpose of simplicity we have based it on Recruitment International’s ‘Top 500 Report’ for 2017. The Top 500 list is ranked according to total revenue generated.
