Good question! You probably should phone H&F parking and ask whether they are suspending the CPZ charges in your street for the duration of the works, which would seem fair. In my experience of this sort of work, although the contractors say you won't have access, I think that's just to cover themselves, as most of the time you'll probably be able to get in and out, and local negotiation can help to minimise problems. I've known a road to be officially "closed", buses diverted etc., but actually you could drive, bumpily and carefully, all along it for most of the "closure".
