Rational bit of me thinks that chances of catching covid are slim, chances of catching from cleaner (and not from a shop for example) are probably slimmer still if not negligible. I do still feel funny about it though, it'll be odd having someone coming into our home after all this time without having anyone else here.
In normal circumstances our cleaner would come when we're all out, and it would be several hours after she left before we were home. Now we'll all be at home WFH and trying to keep out from under her feet.
We have settled into 'living quietly' remarkably well and whilst things are going back to normal we're not feeling the need to rush out to busy places yet - more because I find crowds stressful and I've got out of the habit than because of concern about covid.
If we didn't already have a really brilliant cleaner there's no way I'd be looking for one now. But it feels daft to keep paying her to do nothing if she's happy to come back. It also feels really bad to give her notice which if it weren't difficult for her to replace us, I'd probably happily do now, mainly because I'm at home all day and clean as I go. It feels crazy to be feeling pressured to pay someone to come into our home to do jobs I could easily do myself. 
Am I needing to wobble my head and get her back, is it reasonable to give her notice (e.g. 3 months paid), or have I missed something from my reasoning?
To avoid drip feed later - she's a great cleaner, we've voluntarily continued to pay her throughout, we haven't suffered a drop in our own income, she runs a legitimate self employed business (so maybe also will get some govt support too) and seems to be normally in high demand.
