Our standard working hours are 9:30 – 17:30, but we offer the ability to flex around core hours of 10:30 – 16:30 to give our people flexibility on how they manage their working day, whether that’s in the office or working remotely.

We encourage open conversations between our people and managers to help navigate high‑need periods and individual circumstances. Our goal is to create an environment where people feel genuinely supported to do their best—both in their careers and in their lives outside of work.
