Hello can you confirm what your question is in relation to this please?
If you are asking if you are able to go or not, then as long as local government guidelines are followed I do not anticipate any issues. Boris Johnson announced a three tier Covid lockdown restrictions for England and different parts of England will be split up into 'medium', 'high' or 'very high' local Covid alert levels under the new system.
Subject to what tier your local area falls under will determine if you are able to go or not. You can find out the coronavirus restrictions in your area here https://www.gov.uk/find-coronavirus-local-restrictions
If your area is under tier three it is very high and tougher restrictions are in place.
If it is under tier two, it is high however, two households may be allowed to meet outdoors in a private garden, as long as the rule of six and social distancing guidelines are followed. There is advice for people to minimise their journeys if they live in an area of 'high' alert.
If you are under Tier 2, and it is just the 3 of you, it appears you will be able to proceed although it will be frowned upon though it is different if you were in a tier 3 and very high where you could possibly get fined.
I hope this helps. Thank you again for visiting JustAnswer, please let me know if you need me to clarify anything or if you have any additional questions. I am happy to help.
