Just finished a fitted kitchen (to a 'good' standard). Invoiced the client based on £110 per day - Looks like it'll be going through the legal route, as he seems to think he's been ripped off!
Surprising how different people's opinions can be.
It's worth weighing up just what is involved in a kitchen refit, and just what standard you're expecting. What one client considers an acceptable standard, another would class as unacceptable.
It's important to clarify just what standard you're wanting. And you have to be prepared to accept that a higher standard will take longer to achieve, and if you're a bit finickity (not saying there's anything wrong in that), that in itself will add extra time. Lots of things can have an influence on the time factor - size of tiles, whether tiles are textured or likely to need more precise joints, or problamatic or easy when grouting etc.
If found that appliance power points subsequently need re-positioning (as happened to my job recently) 'cause the back of the appliance doesn't have space to accomodate it, and is being pushed out slightly, again it's more time. So many things that at first you don't even consider.
If there are integrated appliances, inset hob etc.
Job I've just completed involved electrics (1st & 2nd fix), plumbing (sink, w'machine, outside tap), duct for hood along corner of ceiling to o'side wall through brick and made good, joinery - incl some tailor made units and pipe boxed in, plastering, scribed w'top mitres (two), cornice & pelmet (ten mitres each), tiling both floor & walls. Remove & replace sink again 'cause first was defective (client purchased) (second was defective also, but that's another story). Oven and hob changed for new (when eventually delivered by (client's) supplier), all elec accessories changed to chrome.
And along the way, a number of other bits like dealing with a troublesome washing machine, a troublesome shower, being called out on the Sunday to fix the flush on the loo, swap a socket on the landing, put locks on the garden shed etc etc etc.
Then when client sees bill, says something about "How difficult can it be to screw some cupboards to the wall?"
