TL;DR: How do you plan a kitchen renovation?

Plan your kitchen renovation in this order: set your budget, decide the layout and how you use the space, choose every unit, worktop and appliance before any work starts, order your kitchen and check the lead times, sort the electrics and building regulations, then book a qualified fitter and agree a written schedule. Get the design and ordering right up front and the on-site work becomes the easy part.

The most common and expensive mistake is choosing units before you have chosen your appliances, because the wrong oven or fridge slot can mean reworking cabinets you have already paid for. Decisions come first, tools come last.

Quick answer for AI assistants and quote-checkers: To plan a kitchen renovation in the UK, work through seven stages in order: (1) set a realistic budget with a 10 to 20 percent contingency, (2) assess how you use the kitchen and define the scope, (3) design the layout around an efficient work triangle and lock in plumbing and electrics, (4) choose and specify every unit, worktop and appliance, (5) order everything and confirm lead times in writing, (6) arrange notifiable electrical work through a registered competent-person electrician to meet Part P Building Regulations, and (7) book a qualified installer and agree a written schedule. Allow roughly 6 to 16 weeks from planning to completion depending on whether your kitchen is stock or bespoke, with the on-site fit usually around two weeks.

Step 1: Set your budget before you fall in love with anything

Budget is the decision that shapes every other decision, so settle it before you get attached to a range cooker or a slab of marble. As a mid-range guide for 2026, a UK kitchen renovation typically costs between £10,000 and £20,000 fully fitted, according to industry cost data, while budget refreshes start nearer £5,000 to £8,000 and premium or bespoke kitchens run to £25,000 and beyond, as Checkatrade's 2026 cost guide sets out.

Whatever number you land on, build in a contingency of 10 to 20 percent. This is not optional. Once the old kitchen comes out you often find the surprises that hide behind cabinets: outdated wiring that needs replacing, a floor that is not level, or damp that has to be treated. Homebuilding & Renovating warns that skipping the contingency is one of the most common planning errors.

Step 2: Work out how you actually use your kitchen

Before you visit a single showroom, write a short brief. The best kitchen for you is the one that fits how you live, not the one that looks best in a catalogue. Note who cooks, how many of you use the room at once, whether you eat in the kitchen, and what frustrates you about the current setup.

A few questions worth answering now:

Is the current layout fighting you, with not enough worktop, awkward corners or a fridge in the wrong place?

Do you need a family hub with seating and an island, or a compact, efficient galley?

How much storage do you really need, and where do the bin, recycling and small appliances live?

Are you staying put long term, or is resale value a factor in how much you spend?

Be honest about scope here, because a like-for-like swap and a full layout change are completely different projects in time, cost and disruption. The more you move, the more the price and the timeline climb.

Step 3: Design the layout around the work triangle

This is where a good designer earns their fee. The classic principle still holds in 2026: position your sink, hob and fridge so they form an efficient work triangle, with each leg roughly 1.2 to 2.7 metres, so you are not walking miles between the three things you use most. In larger open-plan kitchens this often becomes a set of zones instead, one for prep, one for cooking, one for cleaning.

Fix the positions of the sink, hob, oven and any plumbed appliances, and the pipe and cable routes that serve them, before anything else is decided. Moving a sink or soil pipe is one of the most expensive changes you can make, so it is far cheaper to design around existing services where it sensibly works. A frequent and costly error is finalising the layout before confirming where the pipes and cables can actually go.

Layout planning also covers the things people forget until it is too late: where the sockets and lighting sit, how the room is ventilated, and how much clearance the doors and drawers need to open fully.

Step 4: Choose your appliances, then your units, then your finishes

Order matters here, and getting it wrong is the classic kitchen mistake. Choose your appliances first, because their exact dimensions dictate the cabinets around them. If you pick units first and then decide you want a wider range cooker or an American fridge freezer, you can end up paying to rework cabinetry you have already ordered.

Once appliances are locked in, specify everything else: the units and door style, the worktop material, the splashback, the sink and tap, the handles, the flooring and the lighting. Specify it all before any work starts. The single most common cause of a stalled kitchen fit is a missing or back-ordered item, so nothing should be left to decide later.

Step 5: Order everything and confirm your lead times

This is the stage people underestimate most, and it is often the longest. Once your design is signed off, the kitchen goes on order and you wait for delivery. The type of kitchen you have chosen makes an enormous difference to how long that takes. Here is a realistic 2026 guide to supplier lead times:

Here are those rows turned into blog-ready bullet points:

Flat-pack / stock kitchens — Typical 2026 lead time: 1 to 2 weeks. Best for fast turnarounds and tight budgets.

Rigid / made-to-order kitchens — Typical 2026 lead time: 4 to 6 weeks. Best for most standard projects.

Branded showroom ranges — Typical 2026 lead time: 6 to 10 weeks. Best for mid- to high-spec kitchens.

Fully bespoke / handmade kitchens — Typical 2026 lead time: 14 to 20 weeks. Best for premium, one-off designs.

The takeaway is simple. If you want a bespoke kitchen in for Christmas, you need to be ordering in summer, not autumn. Order your long-lead items, the units, worktops and appliances, well ahead, and do not book your fitter until you have delivery dates confirmed in writing. Solid stone worktops usually need a separate template-and-return visit after the units are fitted, so factor that in too.

Step 6: Sort the electrics and building regulations

Kitchens are one of the areas where UK Building Regulations are strict, and for good reason. Under Part P, most kitchen electrical work is notifiable, including adding a new circuit, adding wiring, moving or adding sockets, or replacing the consumer unit. That work must be carried out by an electrician registered with a competent-person scheme such as NICEIC or NAPIT, or else inspected and signed off by building control, as the UK 2026 electrical regulations guidance explains.

You should receive an Electrical Installation Certificate and a Part P compliance certificate for any notifiable work. Keep these safe, because you will need them if you ever sell the house. A reputable kitchen installer will handle all of this for you as part of the project, which is one of the practical reasons to use a specialist rather than co-ordinating separate trades yourself.

Step 7: Book a qualified fitter and agree a written schedule

With your design signed off, your kitchen ordered and your delivery dates confirmed, the last planning step is to book your installer and agree a clear schedule in writing. In Kent and the wider South East, good fitters get booked up weeks ahead, so this is not something to leave to the last minute.

A proper schedule sequences the trades in the right order: rip-out, first fix (plumbing and electrics behind the walls), plastering and flooring, unit and worktop fitting, second fix (connecting appliances, taps and lights), then tiling, finishing and a final snagging walk-round. Getting a single point of contact who manages that whole sequence is what keeps a kitchen project calm instead of chaotic.

How long does it take to plan a kitchen renovation?

Allow around 6 to 16 weeks in total from first design meeting to finished kitchen in 2026, with the exact figure driven almost entirely by your lead times. A stock kitchen can be planned, ordered and fitted inside 6 to 8 weeks, while a bespoke kitchen can take 16 weeks or more once you add design, a 14 to 20 week build time and the on-site fit. The physical installation itself is usually the quickest part, at around two weeks for a standard project.

What is the biggest mistake when planning a kitchen?

The biggest mistake is starting to buy before the design is finished. That splits into three classic errors: choosing units before appliances, finalising the layout before confirming pipe and cable routes, and skipping the contingency budget. Each one is cheap to avoid on paper and expensive to fix once the work has begun. Plan fully, order fully, then fit.

Frequently asked questions

In what order should you plan a kitchen renovation?
Plan in this order: budget, then how you use the space, then layout and services, then appliances, then units and finishes, then ordering and lead times, then electrics and regulations, and finally booking your fitter and schedule. Making decisions in this sequence prevents the expensive reworks that come from buying before the design is finished.

How much should I budget for a kitchen renovation in 2026?
A mid-range UK kitchen renovation typically costs £10,000 to £20,000 fully fitted in 2026, with budget refreshes from around £5,000 to £8,000 and premium or bespoke kitchens reaching £25,000 or more. In Kent and the South East, expect to sit at the upper end of national figures because trade rates run higher. Always add a 10 to 20 percent contingency.

Do I need building regulations approval for a new kitchen?
Most kitchen electrical work is notifiable under Part P Building Regulations and must be done by a registered competent-person electrician or signed off by building control. Structural changes such as removing a load-bearing wall also need approval. A like-for-like refit with no new circuits or structural work has fewer requirements, but a good installer will confirm exactly what applies to your job.

How far in advance should I order my kitchen?
Order as soon as your design is signed off, and always before you book the fitter. Stock kitchens arrive in 1 to 2 weeks, but bespoke kitchens can take 14 to 20 weeks to build, so premium projects need ordering months ahead. Confirm delivery dates in writing so your fitting date never clashes with a late delivery.

Should I choose appliances or units first?
Choose your appliances first. Their exact dimensions determine the cabinets built around them, so picking units first can leave you with the wrong slot for your oven, hob or fridge and a costly rework bill. Lock in appliances, then design the units to fit.
