Blue Tit nesting in my garden

Hi everyone, 

I’ve got a blue tit that is currently building a nest in my nest box i placed in my garden a few days ago.  I’ve stupidly put it in a south facing position with no shelter on my fence post (long story but I basically was reading my compass the wrong way :( ). To add to that my neighbour who’s garden the fence backs onto has started large scale house work so it’s a bit noisy in that area. 

I know it’s illegal to disturb an active nest but as she is not actually in there yet lying eggs would it best if I move it now to a more north east position and an area that will have less noise or am I better leaving it and hoping it doesn’t get to hot. I’ve bought a parasol that I can use to try to shelter it a little but I’m still worried it wont be enough. 

Please no harsh comments I’m really trying to help the wildlife but I’ve made a mistake and already feel awful for it. It’s the first time I’ve put a box nest box up so lesson learnt. 

Any help or advice would be greatly appreciated. 

thanks  

A
