You like the kitchen. You do not like the worktop
The doors are fine, the layout works, the appliances are where you want them. It is the surface that has had ten years of chopping boards and hot pans on it. Replacing just the worktop leaves the units, doors and appliances exactly where they are and changes more about how the room reads than anything else you could do to it.
It is a different job from a new kitchen, though, and the differences matter. The template has to be taken with the old worktop still down, the whole room has to come apart and go back together inside a single day, and the units underneath are an unknown until the old top comes off.
That last point is why we survey properly and tell you at template if we can see something that needs a joiner or a plumber first. Discovering it on the day, with your sink in the garden, helps nobody.
Fitted 5–10 working days from template. Deposit at template, balance before installation.
