Meal times in the UK vary from family to family. Generally speaking, English families eat earlier than, for example, in continental Europe. It is important that you check with the family as soon as you arrive, what time breakfast and dinner are served. If these times conflict with your study schedule, you should discuss this with your host. If you have booked half board accommodation and cannot get home on time on a certain evening, you should telephone your host to advise them. They may be able to leave your dinner ready for you to reheat when you return.
