My family and I all tested positive for Covid - luckily we only have mild symptoms.
Our house has a very small garden and my children have been playing outside in the garden a lot. There are builders working in my neighbour's garden and I told them that we had Covid (I was trying to be helpful, in case my children went right up to the garden wall and tried to talk to them). It is, to be fair, a very small garden, with a low wall between them. The barrier was higher but the builders removed a rotten bit of trellis so we can now see right into each other's gardens.
The builder has now told me, in quite unpleasant terms, that our family should not come into our own garden while he is working due to the Covid risk to him.
I believe he is in the wrong and we are in our rights to ignore him, please can anyone confirm this?
My neighbour is actually lovely but is away on holiday at the moment. I definitely don't want to cause any problems for her but, at the same time, I can't expect my kids to stay out of their own garden every day?. We've already had to cancel our planned holiday for next week and lots of other fun activities 
I asked the builder for his schedule for when he will be working (so that we could plan our outdoor time around this), and refused to engage in any kind of conversation, saying that I needed to speak to my neighbour.
