A kitchen designer creates a functional and aesthetically pleasing kitchen plan tailored to a client's space, lifestyle and budget. They produce technical drawings for cabinets, worktops, appliances and services such as plumbing and electrics, and may also project-manage the installation. Kitchen design is not a regulated profession in the UK but the KBSA (Kitchen Bathroom Bedroom Specialists Association) is the leading industry trade body. KBSA members must meet defined standards of professionalism and trading, and are subject to a code of conduct. Kitchen showroom designers typically offer their service free as part of a sale; independent designers charge a fee.
What they do
- Conduct a measured survey of the existing space
- Produce 2D floor plans and 3D renders of the proposed kitchen
- Specify cabinetry, worktops, sinks, taps and handles
- Select and specify built-in appliances
- Plan lighting - task, ambient and decorative zones
- Coordinate plumbing, electrics and gas service positions with trades
- Produce detailed technical drawings for fitters
- Project-manage the installation process (if full-service)
- Advise on flooring and decorative finishes
When you need one
A kitchen designer adds most value on complex layouts, open-plan extensions, or when you need detailed technical drawings to brief trades and obtain competitive quotes.

Qualifications to look for

Verified reviews from Which? Trusted Traders and Checkatrade can supplement professional membership as a sign of good trading standards, particularly for smaller independent kitchen fitters who may not hold KBSA membership.

Do I need a separate kitchen designer and fitter?
Not always. Many kitchen retailers and showrooms offer a design-and-install service where their own or partner fitters install the kitchen they have designed and supplied. Alternatively you can use an independent kitchen designer (who produces drawings and specifications) and then source your own fitter separately - this can give you more flexibility on product choice and price but requires more coordination. An independent kitchen designer typically charges a design fee rather than making their margin on the supply of goods.
How much should I spend on a kitchen?
A general industry guideline is to spend 5-10% of the value of your home on a kitchen. For a house worth £400,000 that suggests a kitchen budget of £20,000-40,000 all in - including cabinetry, worktops, appliances, and installation. Budget kitchens start from around £5,000 supply and fit; mid-range bespoke kitchens typically cost £15,000-35,000; and high-end bespoke kitchens can cost £50,000-100,000 or more.
What is the kitchen work triangle?
The kitchen work triangle is a design principle that links the three primary work zones - the sink, the hob and the refrigerator - in a triangle. The principle holds that each side of the triangle should be between 1.2m and 2.7m, and the total perimeter should be between 4m and 8m. In modern open-plan kitchens the work triangle has evolved into a work zone approach with dedicated zones for food prep, cooking and cleaning, but the underlying principle of efficient movement between the key points of activity remains sound.
