You can spend a lot on kitchen & bathroom upgrades on a new-build or very little. Which one is right depends on measurements, not on the quote. That local pattern is baked into the quote, not discovered on the day. Nothing is charged for on the basis of a guess. Where a reading is borderline, it is reported as borderline. Materials matched to the stock is the part worth confirming rather than assuming.
A fair amount of this work is preparation: confirming access constraints priced into the diary, planning the route, agreeing what happens if something unexpected appears behind the plaster. Which is why the price follows the test rather than the other way round. Kitchen & bathroom upgrades on a new-build sits somewhere between routine and urgent depending on what the property is doing right now.
