So in the grand scheme of things this doesn't really matter, but it's bugging me and I've struggled to find a definitive answer on gov.uk or through Google.
DM lives in the north of England and her partner lives in the south. (Became 'more than friends' a few years after his wife and my DF both died, and they're very cute together.)
Neither wants to give up their own house, so they've tended to visit each other for a week or two at a time and also have some time apart, in their own houses. Since March they have stayed together at all times, mostly down at his, but coming up north together from time to time to stay at hers.
They've been down south for a few months but are planning to come up north again this weekend. Right now they're in Tier 3. Planning to travel to Tier 4, to stay for a few weeks before returning again.
They consider themselves to be one household, and accordingly have a support bubble down south with a relative of DM's partner who lives alone. However, in order to move freely between their two individual homes, wouldn't they have to be each OTHER'S support bubble and therefore not see anyone else indoors? I don't think they can be one household with two separate homes and just travel between them as they fancy? Especially as it's a long way and they're moving from Tier 3 to 4.
However they say that they are partners who have two separate homes, but are one household and can travel freely between the two houses.
I think they are bending the rules quite a bit and, more importantly, taking a completely unnecessary risk by travelling the length of the country in freezing weather just because DM hasn't been home for a few weeks and fancies a change of scenery. Especially when they're travelling into a higher Tier. Even if it's not against the law, it's certainly not in the spirit of it right now. Isn't travelling between two homes for no good reason exactly the kind of thing that some MPs had to resign over back in the first lockdown?
Not planning to convey responses to DM by the way, they'll travel up regardless and I'm not going to argue any further. It's just bugging me so I thought I'd see what MN thinks.
