We are having ours redone in 3 weeks!
However, we have an open plan kitchen/utility and are not changing the layout at all as it works perfectly. It's just that our 2005 refit is now looking very tired.
We are not having anything fancy inside the cupboards, under cabinet lighting or built in appliances - had all the bells and whistles in a hugely expensive German kitchen at our last house and we found those were a waste of money for us.
We have a Rangemaster cooker - still immaculate after 18 years - plus freestanding fridge, dishwasher, washing machine, microwave and tumble dryer all of which have been bought during the last 18 months. (We also have 2 virtually brand new air fryers too - our 2 chest freezers are in the garage accessed via the utility area.)
Basically, we are just replacing the cupboards and drawers, worktops - not quartz or granite as we have to have thick worktops with curved edges as we have a disabled adult DC who has horrendous seizures - flooring, tiling and having some additional electricity sockets plus there will be some replastering involved.
The total bill will be around £17k - £18k. Independent kitchen/bathroom specialist - same company redid both of our bathrooms over the past 2 years - and the quality of products is very high. However, we are North Midlands and the price did include quite a hefty discount as we are repeat customers for the third time.
