We introduce Permanent and Interim / Temporary candidates to employers throughout the UK and abroad. Our clients range from FTSE 100 to SME organizations and we successfully deal with opportunities at all levels from Board level Executives through to roles for new Graduates.
There is a good reason why Onyx is the partner of choice for many prestigious organisations and high calibre candidates: – Put simply, we are genuine in wanting to deliver the most effective solution to your individual needs.
Our mission is to work closely with both clients and candidates in a consultative and ethical manner to develop long-term relationships that are beneficial to all parties. We achieve our high level of customer service by employing experienced consultants and through the flexibility and fast response that an independent owner managed business can provide.
This professional and personalised approach has been well received and a measure of our success is the number of both clients and candidates who return to work with us on a regular basis.


We are mature, experienced, highly professional and consultative (and we have a sense of humour so like to work with clients and candidates who have one too!)
