With the current tier system it can be hard to know what to do about your cancellation policy.
Government guidelines advise you to avoid unessential travel between different tiers. As the tiers change it may mean you get a few cancellations.
The Competitions and Markets Authority advises that “where consumers have paid money in advance for services or goods that they have yet to receive, they will generally be entitled to obtain a refund”.
You could offer your guests a refund or you have the option to ask customers to reschedule their visit. It’s up to you how to handle your own cancellation policies, but you should have the option of a refund available for your customers.
