Re: How much should it cost?
Hi madmacca
I would recommend calling a reputable plumber first to get that side of the work done as most appliance engineers/installers will only connect to suitable existing supply/waste.
Installation costs vary across the UK and it depends heavily on whether it is an integrated unit or freestanding.
You should be able to find someone to install it here once you have the plumbing done, but it may be worth asking the appliance engineer if he can recommend one 🙂
Hope this helps.
Dave.
