The reason kitchen projects overrun is almost never the units. It's the gaps in between: the electrician who can't come until the fitter's finished, and the fitter who can't finish until the electrician's been.
Acorn fits kitchens and does the electrical work, which removes that entire category of delay. First fix happens when the walls are open. Appliances land on circuits that were planned for them. Under-cabinet lighting was designed in before the units went up, not chased in afterwards.
Not every kitchen needs replacing. If the units are sound, new doors, worktops, a replacement sink or a few running repairs can transform how a kitchen looks and works for a fraction of the cost, and we're just as happy to take that on.
