Application process

Our apprentice vacancies will open in the fourth quarter of each year and we aim to close early in the first quarter of the following year.

Applications will be sifted for suitability and then passed to line managers who will short list those candidates they would like to invite to interview and or assessment centre.

Successful applicants who are invited to attend an interview/assessment centre will be advised of the outcome and a start date agreed with the hiring project and the candidate.

We aim to onboard our annual cohort through July/August/September for a start at college in September, but there may other opportunities available throughout the year depending on the apprentice training provider/college.

Training providers can be either colleges, commercial training providers or universities. The training provider selected for your apprenticeship will depend on the discipline, the level of your apprenticeship and the delivery method most suitable.
