An outdoor kitchen in the UK can cost anything from a couple of thousand pounds for a modular grill cabinet to £40,000+ for a bespoke, covered outdoor room. That’s an enormous range, and most of it comes down to three decisions: modular or built-in, which appliances, and whether you’re adding a roof over the top.
Having helped homeowners plan garden projects across that whole spectrum, we’ve broken outdoor kitchen costs down honestly - by build type, by component, and by what actually drives the final number - with real UK pricing for 2026.
Quick Price Summary
| Outdoor Kitchen Type | Typical Cost |
|---|---|
| Single modular cabinet (grill + storage) | £1,500-4,000 |
| Modular fitted kitchen (grill, prep, fridge) | £4,000-9,000 |
| Mid-range built-in (sink, fridge, good worktop) | £9,000-18,000 |
| Premium built-in (pizza oven, multiple appliances) | £18,000-35,000 |
| Luxury covered outdoor kitchen | £35,000-60,000+ |
These figures include the kitchen and its appliances. A covered structure, extensive groundwork, or a gas and water connection can each add meaningfully on top - we cover those below.
The Three Ways to Build an Outdoor Kitchen
Almost every outdoor kitchen is one of three things, and the choice sets your budget more than anything else.
Modular (Freestanding)
Pre-made units - a grill cabinet, a prep cabinet, a fridge cabinet - that sit on a hard surface and connect together. No masonry, minimal groundwork, and you can start with one unit and add more later.
- Cost: £1,500-9,000 depending on how many units
- Best for: Existing patios, tighter budgets, renters or anyone who may move
- Trade-off: Looks like furniture rather than architecture, and quality varies widely
Built-In (Bespoke)
A permanent structure built on site - a block, brick, or steel-frame carcass, clad and topped with a worktop, with appliances dropped in. This is the kitchen that looks like part of the house.
- Cost: £9,000-35,000+
- Best for: Long-term homes, design-led gardens, frequent entertaining
- Trade-off: Higher cost, more disruption, and it’s not coming with you if you move
Hybrid
Increasingly common - a built-in run for the cooking and worktop, with modular or freestanding pieces (a fridge, a kamado, a pizza oven on a stand) alongside. It lets you spend where it shows and save where it doesn’t.
What You’re Actually Paying For
When a quote lands at £20,000, it helps to know where the money goes. A built-in outdoor kitchen breaks down roughly like this:
| Element | Share of Budget |
|---|---|
| Appliances | 30-50% |
| Cabinetry / structure | 20-35% |
| Worktop | 10-20% |
| Groundwork & base | 5-15% |
| Utilities (gas, water, power) | 5-15% |
Appliances are usually the single biggest line, which is good news - it’s the part you control most directly by choosing what you genuinely need.
Appliance Costs
This is where to set your priorities. A grill is essential; everything else is a choice.
| Appliance | Typical Cost (built-in) |
|---|---|
| Gas grill / BBQ | £800-5,000+ |
| Pizza oven | £500-3,000 |
| Kamado / ceramic grill | £700-2,000 |
| Outdoor fridge | £400-1,500 |
| Side burner | £200-800 |
| Plancha / teppanyaki plate | £500-2,500 |
| Sink & tap (before plumbing) | £300-1,000 |
| Storage drawers & doors | £150-600 each |
A common, sensible mid-range appliance set - a quality built-in gas grill, a side burner, an outdoor fridge and a sink - comes to roughly £2,500-5,000 before anything is built around it. If a pizza oven matters to you, the best pizza ovens sit in our outdoor kitchens collection alongside the cooking units.
Worktop and Cabinetry Costs
Cabinetry / Carcass
- Modular stainless or composite units: £500-2,500 per unit
- Bespoke block or brick carcass: £3,000-10,000 for a typical run, built and clad
- Steel-frame and board systems: £2,000-6,000 as a carcass before cladding
Worktops
Outdoor worktops have to handle frost, UV and heat, which rules out a lot of indoor materials.
- Porcelain: £200-400 per linear metre - the practical all-rounder
- Granite: £250-450 per linear metre - durable and traditional
- Concrete (cast): £150-350 per linear metre - on-trend, needs sealing
- Stainless steel: £300-500 per linear metre - commercial look, marks easily
A typical 3-4 metre run in porcelain adds £700-1,600 to the build.
Utilities: Gas, Water and Power
This is the part that quietly inflates budgets, because it often means a tradesperson and a trench.
- Electrics (outdoor sockets, lighting, fridge supply): £300-1,000
- Gas line (connection to mains): £500-2,000, more if the run is long
- Water and drainage (for a plumbed sink): £500-2,000
You can sidestep all three. A grill running off a bottle, no sink, and battery or solar lighting keeps a kitchen completely off-grid - and many of the best modular setups are built exactly this way to avoid the cost and the regulations.
The Covered Question
A roof over your outdoor kitchen is the difference between a fair-weather setup and one you use in October. It’s also a substantial separate cost.
- Aluminium louvered pergola over the kitchen: £4,000-15,000+
- Timber pergola or canopy: £1,500-6,000
- Garden room / fully enclosed: £10,000-30,000+
If a cover is in your plans, factor it from the start - it changes the base, the drainage and sometimes the electrics. Our pergola cost guide breaks the covered-structure options down in full.
Installation and Groundwork
What you’ll pay to build, beyond the kitchen itself:
Base / foundation:
- Using an existing patio: £0
- New slab or reinforced base: £500-2,500 depending on size and ground
Build labour (built-in):
- Simple single run: £1,500-3,500
- L-shape or island with services: £3,500-8,000
Difficult conditions - sloped ground, poor access, or a long services run - can add £1,000-3,000 on their own. As with any garden build, level, accessible ground with a hard surface already down is the cheapest starting point.
Modular vs Professional Build: Which is Right?
Choose Modular If
- You’re working to a defined budget
- Your patio is already laid and level
- You want to start small and expand
- You might move within a few years
- You’d rather avoid gas and plumbing work
Choose a Built-In Build If
- This is a long-term home
- You entertain often and want a proper cooking space
- Design and a seamless look matter to you
- You’re already having landscaping done (combine the projects)
- You want it to feel like an extension of the house
Hidden Costs to Budget For
Beyond the headline quote, plan for:
- Delivery and crane/hiab for heavy units or stone: £100-500
- Weatherproof covers for appliances: £100-400
- Outdoor-rated furniture to use the space: £1,000-5,000
- Lighting and heating to extend the evenings: £300-2,000
- Annual servicing of gas appliances: £80-150
How to Get the Best Price
- Decide appliances first. They’re the biggest line and the easiest to over-spec. Buy the grill you’ll use, not the one that impresses.
- Start modular, build later. A single grill cabinet now, with a base sized for the full kitchen, lets you expand without redoing groundwork.
- Combine with other landscaping. If you’re laying a patio or adding a pergola, building the kitchen into the same project saves on access, groundwork and labour.
- Order off-season. Autumn and winter are quieter for installers and some suppliers discount.
- Go off-grid where you can. Skipping the gas line and plumbing removes cost, trades and regulation - bottle gas and a freestanding sink work for most people.
- Get three quotes. Built-in kitchen prices vary enormously between landscapers; specifications often differ more than the headline number suggests.
Price vs Value
The cheapest outdoor kitchen isn’t always the best value.
A £2,500 modular grill cabinet that gets used twice a month for six months a year still earns its place - that’s the entry point, and there’s no shame in it.
A £15,000 built-in kitchen that turns the garden into the place you eat all summer, host friends, and cook properly outdoors, used a hundred times a year for fifteen years, works out at around £10 a use. Framed that way, the “expensive” option is often the better value - provided you’ll genuinely use it.
The mistake isn’t spending too much or too little. It’s building a kitchen that doesn’t match how you’ll actually live in the garden.
Our Recommendations by Budget
Under £4,000: A quality modular grill cabinet with storage on an existing patio. Add a fridge cabinet later. Off-grid, no trades, immediate.
£4,000-10,000: A modular fitted run - grill, prep, fridge, maybe a side burner. Optional electrics for lighting. A genuinely capable kitchen without the cost of a built-in.
£10,000-20,000: A bespoke built-in run with a porcelain worktop, a proper appliance set, and electrics. The sweet spot for most long-term homes.
£20,000+: A built-in kitchen with a pizza oven, multiple cooking appliances, a plumbed sink, and a covered structure overhead. At this level you’re building an outdoor room, not a barbecue area - and it should be designed as one.
