How much it costs to fit a kitchen depends on several factors. This can be anything from the size of your space, whether you are going to design and install the kitchen yourself or work with a professional, and the style of your décor. Having said that, it will make the whole process less stressful and more organised if you have a rough idea of a budget in mind.
If you are employing a professional, we would always recommend getting a few quotes before making your decision. Check customer reviews and ask friends and family for recommendations or go through a registered trade association, like the FMB (Federation of Master Builders) to make sure you find a skilled and reliable tradesman for the job.
Always check what is included in the package if you choose to work with a company to design the layout of your kitchen. The KBSA (Kitchen Bathroom Bedroom Specialists Association) recommend that you should not pay in full for your kitchen in advance or pay a deposit of more than 25%. They also advise that you ask for a written quotation detailing every little aspect of the project from fitting, flooring and any structural alterations you have discussed like knocking the connecting wall through.
