Contractually, we work 09:00 - 18:00 UK time every day with 1hour for lunch and also benefit from wellbeing Seasonal Hours adjustments.
In reality, we're as flexible as we can and trust our people to take ownership of their hours — we’re contracted to work 40 hours per week.
Start earlier, leave earlier, take a shorter lunch or leave a bit later, it's totally up to you (provided you are performing at the level we expect and it does not adversely impact our overall ability to achieve our goals). We care most about outcomes and do not see it as strictly relating to your hours at your desk.
You should be available for meetings to be scheduled as enables your team and your own performance. Talk to your manager and your team about what works best.
This also depends on your role and the stakeholders you need to be in contact with! Once that's discussed, you're free to organise your time as suits you best outside of meetings.
Talk to your manager first and communicate which core hours you're free so you get invited or caught up with team-wise things.
