Can someone help me with the track and trace guidelines please

Person A goes to work on Christmas Eve.

Person A and person B - from different households - see each other on Christmas Day inside.

Person C, a close contact from person A's work tests positive on Boxing Day

Person A has no symptoms but is told to isolate as per track and trace.

Does person B have to as well? They've not had any contact with person C.

Person B doesn't have to isolate as they weren't the ones in contact with Person C

No.

But if person A got symptoms and a +ve test then they would have to.

Great thank you!

No, they do not, but person B would have to isolate if person A became symptomatic in the days following their Christmas together. So the right thing for person B to do is to follow distancing advice to the letter and avoid unnecessary contact with other other people until at least 48 hours had passed

@chantico thanks, so once 48 hours has passed A and B can see each other - but I thought it was 5 days for contact tracing not 2? Or is it that if A hasn't developed symptoms in two days they are unlikely to? So A could go to work tomorrow then they could meet Christmas Day?

I don't really understand your last post. B doesn't need to isolate because A is a contact. A needs to isolate for 10 days from their contact with C (assuming everywhere else is10 days as well now?). If A develops symptoms within 48 hours after seeing B, then B will need to isolate.
