The cost of renovating a kitchen is usually one of the first things homeowners want to know, but getting a clear answer is not always easy. Showroom prices rarely reflect the full cost, quotes can vary hugely, and the final figure often depends on choices around layout, finishes, appliances and materials that you may not have made yet.
So let’s be straight about the numbers: what a kitchen renovation actually costs in the UK in 2026, where the money really goes, the costs that catch people out, and how to keep your budget under control from the start.
Listen to thie summary
How much does an average kitchen renovation cost in the UK?
As a broad guide, most full UK kitchen renovations fall somewhere between £8,000 and £25,000. A straightforward budget refit can start from around £5,600, while higher specification and bespoke kitchens can reach £30,000 to £50,000+.
The range is wide because a kitchen renovation is really several projects happening at once. You are paying for cabinetry, worktops, appliances, flooring, lighting and the different trades required to bring everything together. The figure that matters is not simply the advertised cost of the kitchen units. It is the total once everything required to complete the room has been included.
These are broad UK estimates rather than fixed prices. The size of the kitchen, location, level of specification, appliances, building work and whether services need to be moved can all change the final cost considerably.
What does a kitchen renovation budget actually include?

The unit price you see advertised is rarely the whole cost. A realistic kitchen renovation budget needs to account for several different elements.
Kitchen units and cabinets
This includes the cabinet carcasses, doors, drawers and internal fittings. Prices vary considerably between flatpack kitchens, rigid cabinetry and fully bespoke joinery.
Worktops
Laminate remains one of the more affordable options, followed by materials such as timber, quartz, granite, porcelain and other premium surfaces. Depending on the size of the kitchen, material, templating, cut-outs and installation, worktops can range from a few hundred pounds to several thousand.
Appliances
Ovens, hobs, extractors, refrigerators, dishwashers and other appliances need to be included from the beginning. Integrated appliances can also involve additional fitting and cabinetry costs.
Labour and installation
Your kitchen fitter is only one part of the labour budget. Depending on the project, you may also need an electrician, plumber, plasterer, decorator, tiler or flooring installer.
The extras that are easily forgotten
Lighting, flooring, tiling, waste removal, skip hire, decorating and making good walls after the old kitchen has been removed can all increase the final figure.

For a standard kitchen, fitting labour can typically cost around £2,000 to £6,000, although complex projects can cost considerably more. Kitchen fitters commonly charge around £250 to £350 per day, with rates often higher in London and the South East.
A straightforward installation may take around five to ten working days, but the overall renovation can take longer once electricians, plumbers, plasterers, tilers and other trades are involved.
This is also why changing the kitchen layout often costs significantly more than replacing cabinetry within the existing footprint. Moving a sink, hob, sockets or major appliances can require changes to plumbing, electrical circuits, ventilation and sometimes flooring or walls.
From our design team: Before changing a kitchen layout, we look at what the new arrangement actually improves. Moving services can be worthwhile if it solves a layout problem, but changing everything simply for the sake of creating a different arrangement can use a large part of the budget without necessarily improving the room.
What is a reasonable budget for a small kitchen refit?
For a small kitchen, a straightforward refit that keeps the existing layout could start from around £5,000 to £8,000, particularly when using entry-level units, laminate worktops and reasonably priced appliances. If you choose mid-range cabinetry, integrated appliances or stone worktops, a small kitchen can easily move into the £8,000 to £12,000+ range.
Small does not necessarily mean cheap. A compact galley kitchen with quartz worktops, good appliances and carefully planned storage can cost more than a much larger kitchen fitted with budget cabinetry.
Designer insight: Small kitchens are often where careful planning matters most. When space is tight, losing even a small amount of storage or placing an appliance in the wrong position can affect how the entire kitchen functions.
Is it cheaper to buy a kitchen online or from a showroom?
Online kitchen suppliers can be cheaper, particularly when comparing similar cabinet specifications, but buying online is not automatically the lowest-cost option. A showroom package may include services such as measuring, planning, delivery coordination or installation that are charged separately elsewhere. With an online supplier, you may take on more of the planning and coordination yourself.
The more important saving often comes from getting the design right before anything is ordered. An incorrectly planned kitchen can lead to cabinets that do not fit properly, awkward appliance positions, insufficient clearance or expensive changes to plumbing and electrical services. Comparing like for like is therefore more useful than comparing cabinet prices alone.
What percentage of a home’s value should you spend on a kitchen renovation?
One commonly used rule of thumb is to spend around 5 to 10 per cent of the property’s value on a kitchen renovation, particularly where resale is an important consideration. On a £400,000 property, for example, that would suggest a very broad budget of £20,000 to £40,000.
It is only a guide, not a rule you need to follow rigidly. The condition of the existing kitchen, the value ceiling for properties in your area, the type of home and how long you intend to remain there are all more important considerations. A kitchen should ultimately feel appropriate for the property. If you spend far more on a renovation than the value of neighbouring homes can support, you may struggle to recover the full cost when you come to sell.

A well-designed kitchen can make a property more attractive to buyers and may improve its value, but there is no guaranteed percentage return from replacing a kitchen. If the existing kitchen is old, damaged or poorly planned, improving it can make a substantial difference to how buyers perceive the property. If the existing kitchen is already in good condition, however, an expensive replacement may not be recovered pound for pound.
For resale, design and proportion matter as much as specification. A kitchen with a practical layout, good lighting, appropriate storage and finishes that suit the property can be more appealing than one that simply uses the most expensive materials available.
What are the hidden costs in a kitchen renovation?
The expenses that catch homeowners out are often not the cabinets themselves. They are the things underneath, behind and around the kitchen.
Making good
Removing an old kitchen can reveal damaged plaster, uneven walls or surfaces that need repairing before the new kitchen can be installed.
Electrics and plumbing
Moving sockets, adding new circuits, installing appliance supplies or relocating the sink can all increase the labour cost.
Flooring
A new kitchen often means repairing or replacing the existing floor, particularly if the layout changes.
Waste and skip hire
Removing cabinetry, worktops, appliances and old finishes can create a surprising amount of waste.
Building work
Opening up the kitchen, removing walls, altering doorways or making structural changes can introduce additional costs for builders, engineers and Building Regulations approval.
Lighting
Lighting is another area that is frequently missed until too late. General lighting, task lighting, pendants, under-cabinet lighting and new switching arrangements should ideally be planned before electrical work begins.
How much contingency should you allow for a kitchen renovation?

It is sensible to keep around 10 to 15 per cent of your overall kitchen budget aside as a contingency, particularly when renovating an older property. You do not always know what is behind existing cabinets until the kitchen is removed. Old wiring, plumbing issues, damaged plaster, uneven flooring or previously hidden alterations can all create additional work.
For a £15,000 kitchen renovation, keeping approximately £1,500 to £2,250 aside gives you some breathing room without immediately compromising the design if something unexpected appears. The aim is not necessarily to spend the contingency. It is to avoid having to remove important elements from the project because the entire budget has already been committed.
Where should you spend and where can you save?
Not every part of the kitchen needs the same level of investment. We would normally prioritise the elements that affect how the room works every day: the layout, cabinetry configuration, worktop durability, lighting and the appliances that you use most. There are then areas where you can often reduce costs without making the finished kitchen feel inexpensive.
For example, standard cabinet carcasses can be paired with better doors or handles, expensive finishes can be concentrated on one focal area, or a statement worktop can be used on an island rather than every surface. The key is deciding where the visual impact and practical value actually are before allocating the budget.
Why planning before you buy matters
A surprising amount of kitchen overspending happens before installation even begins. Cabinetry may need to be reordered because dimensions are wrong. Appliances can be purchased before their position has been properly worked out. A layout change can trigger plumbing or electrical work that was never included in the original budget.
As interior designers, this is why we start with the space and kitchen layout not just the style. We consider how the household uses the space, where food is prepared, how much storage is needed, how people move around the kitchen and how it connects to adjoining living or dining areas. Only then does it make sense to decide where cabinetry and appliances should go.
If you would prefer help with this stage, our online interior design service lets you work directly with our own in-house designers to plan the space before committing to major purchases. Depending on the package, this can include layouts, visual design development, 3D visuals and product specification, helping you make decisions with a much clearer picture of how the finished kitchen will work.
If you want to understand the process first, here is how online interior design works, and if you are working to a tighter figure, our post on luxury kitchen design on a budget shows how to get a high-end look for less.
Planning your kitchen renovation budget
A kitchen renovation is a significant investment, and one of the easiest home projects to overspend on if the full cost is not worked out from the beginning. The number that matters is the complete project budget, including cabinetry, worktops, appliances, labour, lighting, flooring and the less obvious costs that appear once work begins.
Get the layout and specification right first. Decide where spending will make the biggest difference, keep a contingency for unforeseen work, and compare quotes based on the entire project rather than the advertised cost of the cabinets.
