Time for a new kitchen...

I have had a very full few days back in th UK, and unfortunately not been able to see family of friends as have spent all of it helping M. clear our kitchen and two main bedrooms. Plus I was working today! Work on the house starts tomorrow morning, with the aga being removed, a boiler and then kitchen fitted, main bedrooms being replastered, and the upstairs shower being made to work...
In theory I won't be back until November at the earliest, so really hoping it is all sorted and functional by then..... M. Is having to be a project manager, a task he hates, which really isn't his forte... What could possibly go wrong?
