UK Immigration

Mott MacDonald Ltd. are not currently offering sponsorship to candidates under the Skilled Worker visa route in the UK. This decision is as a consequence of the changes made to the Skilled Worker route by the UK Government in April 2024.  

Our ethos is to develop, train and retain our graduates and therefore we are looking for a long-term relationship with our graduates. For this reason, we cannot accept applications from candidates who would be working under the Graduate visa route or other time-limited visas, (irrespective of visa duration), due to their temporary nature and the requirement for sponsorship under the Skilled Worker route in future. 

We continue to welcome applications from candidates who are eligible for alternative immigration routes in the UK, that do not require sponsorship as a Skilled Worker now or in future.
