Does anyone know how long it is taking for test results to come back?

I am in the SE at the minute and waiting for a result! If it's positive, we have to stay in till Christmas Day, so just wondering how much online shopping to try and do now, as I won't be able to go in person.

Mine came back last night, around 60hrs later (negative). East London.

Test available within 30 mins of booking yesterday, tested at 3pm, results before 7am today. NI
