If you do not do this before you arrive it might take you longer to enter the UK. You’ll also need to self-isolate in the place you’re staying for the first 14 days after you arrive, unless you’re travelling from certain countries or territories. You may be fined up to £100 if you refuse to provide your contact details. You may be fined more if you break this rule more than once. You may also be fined up to £1,000 if you refuse to self-isolate, or you could face further action.
