Well, it doesn't sound very much like what we have signed up to. Our kitchen is not being delivered until Aug but we have a specified date and the installation will begin the following Monday (both specified in writing). I can't understand why they cannot give you, at least closer to the delivery date, a more specific day.
I wouldn't like at all the fact that you are supplying your own workmen for electrics/plumbing. This sounds both (a) more expensive, as you will have to specify in advance when you want the plumber and electrician there and their payment will presumably start from when they arrive even if the kitchen fitters are running behind and (b) liable to lead to arguments if the hole in the kitchen cabinet doesn't match up exactly with where the plumber is installing the waste disposal for instance. I can't understand why they would have their own tradespeople so they can sort it all out between them. I can just see the discussions down the line between them about who is to blame for what!
Don't like the fact that cancellation of the kitchen is so heavily weighted in their favour. One hundred and eighty days is half a year!
Our kitchen installation will be guaranteed for a year but the actual units are guaranteed for five years and appliances will have whatever the manufacturer's warranty is.
Yes, I would expect them to leave you with a temporary worktop while the granite template is being made. Is the lack of a temporary surface because you are not getting the actual worktop through them? Whatever the reason is, it sounds like a pain. However, we have been told that our granite worktop will only take a week so not sure why yours would take so long?
Think the 2.5% fee for cc payment is pretty normal.
Have you taken up references from previous clients? Perhaps they could put your mind at ease about how the installation works?
