Passionate about people , sustainability and innovation 

Since inception in 1989, Principle has held the firm belief that investing in people is key to success. Over the years, we have launched and refined programs that support not only training and development but reward and recognition, mental health, wellbeing and both professional and personal support. As a result, Principle team members are engaged, driven and committed.

Working at Principle

We have a robust and thorough recruitment process that helps us select not only the best talent but those who also align with our values and commitment to quality. Principle uses cutting edge technology to remove the guesswork around UK working eligibility.


A dynamic program centred around a monthly newsletter that brings our diverse and dedicated community together to highlight both team and individual achievements, advertise vacancies, promote training opportunities and staff events.

London Living Wage

We pay fairly! Principle became a recognized Living Wage Foundation provider in 2014. Our solutions are always based on the assumption that both existing and prospective clients support this initiative.


Every team member has a personalised training plan, covering both essential and specialised subjects. From English language classes through to highly specialised site specific courses, we have both in-house and external resources to call upon.

Reward & Recognition

Celebrating success is at the heart of what we do. But inviting clients to nominate those from our teams who have gone above and beyond makes it all the more meaningful.


We have selected Richard House Children’s Hospice as our chosen charity. Richard House provides palliative care to children with life-limiting and life-threatening conditions.

As part of our CSR commitment we aim to raise £30,000 for charity to recognise Principle’s 30th anniversary, and our teams across the company are working together to plan fundraising events throughout the year.

This is what Principle is about, being one team
