Our flat is due to have some vents installed one day this week, and one the next. Our landlady has already paid the company for the job and if she cancels she stands to lose almost 1k.
Since the Coronavirus restrictions, myself, DH and our DC’s are barely going outside, we’ve seen no friends or family in weeks, have got out for a walk once in about 17 days - essentially doing all we possibly can to limit our time outside/around others.
I messaged my landlady yesterday to ask if the building work was still going ahead, as I was growing very anxious about having people in our home that we don’t know, especially seeing as the govt advice right now is to not even have your own family over, let alone strangers, and that also, thanks to the lockdown there is nowhere the 5 of us could go for the duration of the vents being installed (should take a few hours).
She wound up telling me that she’s unsure whether or not it’s still going ahead, though she hasn’t heard from the company to say that they’ve pulled out. She also reiterated to me how much money she’ll lose if she cancels the job - which made me feel just lovely! 
- and offered to have myself, DH and our three kids round at her house while the work is being carried out.
Now, not wanting to be rude to the woman we’re renting our home from, I didn’t want to point out that we’re not supposed to go to other people’s homes at the moment, so I ended up having to say to her that if the work really must go through so that she doesn’t lose her money, that my family and I will all just have to stay in my bedroom while the work is being done. Our flat is small, our bedroom is small, there’s five of us, three kids three and under, so not ideal, not to mention the obvious that I just don’t want other people in my home now.
What do I do? If the builders turn up this week, I feel like I can’t turn them away because my landlady will have it out for me that I’ve cost her almost a grand in work that I’ll have refused being done, but I just really don’t want them here.
