A kitchen is the most technical room in the house and often the most expensive, so mistakes are costly and hard to undo. It also has to work as hard as any room in a London home, doubling as a cooking space, a dining spot, sometimes an office or the heart of an open-plan ground floor, frequently in a footprint that is tight or awkwardly shaped. Designing one well is less about picking a door style and more about a sequence of decisions taken in the right order. Get the layout and the working zones right first, and every later choice, storage, worktop, lighting, becomes easier. Choose the units before you have planned the plan, and you will be living with the compromises for years.
Start with how you actually cook and live
Before any mood board, be honest about how the room is used. Do you cook properly most nights, or reheat and graze? Do you need to seat four for breakfast, or six for dinner? Will it be a closed kitchen, or the open-plan hub of the home where cooking, eating and relaxing all happen in one space? In many London homes the kitchen carries the lot. List the demands, rank them, and let the most important shape the plan. A kitchen designed around how you live is a pleasure; one designed around a showroom photograph rarely is.
Understand the working zones and the triangle
Good kitchen design still rests on the relationship between the three things you use most: the sink, the hob and the fridge. Keep these close enough to move between easily but not cramped, the classic "work triangle", and cooking feels effortless. In larger or open-plan kitchens it helps to think in zones instead: a prep zone with worktop and bins, a cooking zone around the hob, a washing zone at the sink and dishwasher, and a storage zone for food and equipment. Arrange those so you are not crossing the room mid-task, and leave generous, uninterrupted worktop beside both the hob and the sink, where the real work happens.
Choose a layout that suits the space
The shape of the room and how it connects to the rest of the home points to a layout:
- Galley: two facing runs, efficient for narrow London kitchens and side-return extensions, but keep at least 1.2m between runs so two people can pass and doors and drawers can open.
- L-shape: units along two walls, flexible and sociable, leaving room for a table in the corner of the space.
- U-shape: three runs of units, maximum storage and worktop, best in a squarer room.
- Island or peninsula: lovely in an open-plan kitchen, but only if you can keep about 1m of clear space all around it; force one into a tight room and it blocks the flow.
In a period terrace the kitchen is often long and thin, which suits a galley or a single run with a slim island. In a new-build or a rear extension you may have the width for an L-shape with an island. Let the room decide rather than the picture you liked.
Work with the services, not against them
The single biggest hidden cost in a kitchen is moving the plumbing, drainage and electrics. Waste pipes in particular need a fall to drain, so relocating a sink or dishwasher far from the existing soil stack can be expensive and sometimes impractical. Before you fix a layout, find out where the water, waste, gas and consumer unit are, and design around them where you sensibly can. Moving the hob or sink a little is normal; moving everything to the opposite wall is a budget decision, not a detail. Plan sockets generously too, including for appliances you may add later, because retrofitting power once the units are in is disruptive.
Plan storage around what you own
Storage is where a kitchen is won or lost day to day. Rather than a generic run of cabinets, plan it around what you actually keep: deep drawers for pans, which are far easier to use than low cupboards; a tall larder for food; a dedicated home for the bin and recycling near the sink; and a spot for the appliances that otherwise clutter the worktop. Take storage to the ceiling where you can to use the full height, especially valuable in smaller London kitchens, and keep the things you use daily within the working zones. Well-planned storage does more for how a kitchen feels than any finish.
Choose worktops and finishes for how you use them
Worktops take the most abuse in the house, so match the material to your life, not just the look. Engineered stone and quartz are hard-wearing and low-maintenance; natural stone such as granite and marble is beautiful but needs sealing and, in marble's case, forgiving of a patina rather than pristine; solid timber is warm but wants oiling; laminate is the budget-friendly all-rounder. For finishes, pick a restrained base of cabinetry and worktop, then add character through the splashback, handles and one or two accent materials rather than a dozen competing elements. London light is often cool and, in lower-ground kitchens, limited, so test colours on the actual walls and units at different times of day before you commit.
Get the lighting in layers
Kitchen lighting has to be both practical and atmospheric, which means working in layers. Task lighting comes first: under-cabinet lights over the worktop so you are not chopping in your own shadow, and good light over the hob and sink. Ambient light fills the room, but avoid relying on a grid of downlights alone, which is flat and clinical. Accent and feature light adds warmth: a pendant or two over an island or table, a low glow in a glazed cabinet. Put the circuits on dimmers and mix warm-toned bulbs so the same kitchen can be bright for cooking and soft for dining. Do not forget extraction: a properly sized, well-vented extractor over the hob is part of the design, not an afterthought.
London-specific considerations
London homes bring their own constraints. Period conversions often mean tight access, so check that units and large appliances will physically get through the hallway, doors and any awkward stairs. Side-return and rear extensions create wonderful open-plan kitchens but need the layout, zoning and lighting handled carefully so the cooking end does not overwhelm the living end. In a flat, consider your neighbours and the building's rules on moving waste and extraction. And in a period property, balancing a modern working kitchen with original proportions and features takes a careful hand, which our guide to interior design for period properties in London covers in depth.
Common kitchen design mistakes to avoid
- Choosing units and appliances before planning the layout and zones.
- Moving the sink or hob far from the existing services without budgeting for it.
- Leaving too little clear space around an island, so it blocks the room.
- Skimping on worktop beside the hob and sink, the two spots you most need it.
- Relying on ceiling downlights alone, with no task or feature lighting.
- Under-planning storage and sockets, then living with clutter and trailing leads.
When to bring in a designer
You can take a kitchen a long way yourself with this order of decisions, and many kitchen suppliers offer a planning service. A designer earns their fee on the harder cases: a tricky open-plan layout to zone, a period room where joinery and proportion need real care, structural changes such as an extension, or a scheme you want pulled together coherently across cabinetry, worktops, lighting and finishes. If you are choosing between suppliers, the Kitchen Bathroom Bedroom Specialists Association lists accredited firms.

Frequently asked questions
Where do I start when designing a kitchen?
Start with how you cook and use the room, then the working zones, not the door style or colour. Fix the layout around the sink, hob and fridge and the existing services first; storage, worktops, lighting and finishes follow. Deciding the plan before the products is what keeps a kitchen practical.
What is the kitchen work triangle?
The work triangle is the relationship between the three things you use most, the sink, the hob and the fridge. Keeping them close enough to move between easily, without being cramped, makes cooking efficient. In larger or open-plan kitchens it helps to think in prep, cooking, washing and storage zones instead.
How much space do I need around a kitchen island?
Aim for roughly 1m of clear space all the way around an island so people can pass, and doors and drawers can open without clashing. If the room cannot give you that, a peninsula or a slim island is usually a better call than squeezing in a full island that blocks the flow.
What is the best worktop for a kitchen?
It depends on how you use the kitchen. Engineered stone and quartz are hard-wearing and low-maintenance; natural granite and marble are beautiful but need sealing and, for marble, tolerance of a patina; solid timber is warm but wants oiling; laminate is the budget all-rounder. Match the material to your habits, not just the look.
How much does it cost to have a kitchen designed?
It varies widely with the size, the finishes and whether structural work or a designer is involved. For a realistic picture of fees and budgets in London, see our dedicated interior designer cost guide.
