On average, it takes between one and four weeks to fit a kitchen, depending on the amount of work needed.
For example, if you fit the new kitchen with everything in the same place as the old one, and there’s no new flooring or decorating, a week is an accurate amount of time to allow. However, if gas, electricity, and water supplies are being moved, walls replastered, and new flooring laid, it adds to the installation time. Similarly, if you’ve chosen stone or composite worktops, these need to be templated and fitted once the kitchen furniture is in place, which can add a couple of weeks.
