A support bubble is where a household with one adult joins with another household. Households in that support bubble can still visit each other, stay overnight and visit public places together.
The police can take action against you if you meet in larger groups. This includes breaking up illegal gatherings and issuing fines (fixed penalty notices). You can be fined £200 for the first offence, doubling for each further offence up to a maximum of £6,400. If you hold, or are involved in holding, an illegal gathering of over 30 people, the police can issue fines of £10,000.When meeting friends and family you should also: follow social distancing rules when you meet up; limit how many different people in total you see socially over any short period of time; meet people outdoors where practical. This is safer because fresh air provides better ventilation.
