Response from James:
Water - pump had just been replaced and all that needed doing was the tank supply switching from one to the other. Details were in the house manual but a neighbour needed to be called to support.
The oven is working fine and has been checked.
There was plenty of clean linen for the guests and the cleaner does what she can each visit - sorry if there was some unwashed towels in the laundry but that's what laundries are for.
Sorry that the previous guests had left some food in the fridge.
