We have recently announced that we will be moving towards a more blended working week – combining office and remote working, leveraging the advantages of face-to-face connectivity and enjoying the flexibility and productivity of remote working.

Our base will be the office, where we connect, collaborate and innovate – and there will be the expectation for everyone to be physically together more time than apart.  For Head Office roles we therefore expect colleagues to spend a proportion of their time in the office location listed on the job description.

We are supportive of colleagues having conversations with hiring managers about what office presence will look like in the context of the role
