Our Values

We want every employee to live the core values of the business:

More than me - Our goals are too big to achieve on our own, it takes diverse skills and various people to achieve greatness.

Care a lot - Doing the right thing is not optional (even when no one is watching). We care a lot about each other, our users, the NHS. We hold each other to the highest standards and earn our reputation every day.

See it thru - An endless pursuit of excellence. We take pride in planning and execution of all types of work - we are not deterred by bumps in the road or adversity, we relish the challenge and we keep going.

Think around corners - We stay ahead of the curve at all times, All of us share a responsibility to challenge the status quo, think out of the box, think creatively, turn problems on their head and turn weaknesses into strengths, it takes deep thought and analytical firepower.

Bounce back & learn - Having a positive mental attitude, resilience, determination to learn and improve. It is better to try and learn than not try at all and being open to changing from what you learned is what makes us successful.

Diversity Promise

We believe that a great workplace is one that represents the world we live in and how beautifully diverse it can be. That means we have no judgement when it comes to any one of the things that make you who you are.
