Outdoor Kitchen Cost UK: What You’ll Actually Pay in 2025
If you have been scrolling through garden makeover photos and wondering what the outdoor kitchen cost UK really comes to, you are not alone. Prices swing wildly depending on whether you bolt together a ready-made unit or commission a bespoke masonry kitchen with gas, water, and electricity. Most UK homeowners end up spending between £4,000 and £15,000 for a quality setup, but the honest range runs from about £700 for a basic prep station to £40,000 and up for a fully serviced build.
The good news is that an outdoor kitchen is one of the few home upgrades that genuinely gets used. Unlike a conservatory that bakes in summer, a covered cooking area adds real value to how you live in your garden. This guide breaks down what you can expect to pay at each tier, what drives the bill, and where you can trim costs without ending up with something that falls apart in two winters.
How Much Does an Outdoor Kitchen Cost in the UK?
Broadly, UK outdoor kitchens fall into three price bands. A budget or flat-pack option runs from £700 to £3,500. A mid-range modular kitchen with a decent grill, worktops, and storage lands between £4,000 and £12,000. A bespoke build with masonry, a pizza oven, and full utility hookups starts around £15,000 and can pass £40,000.
What separates one band from the next is not just quality. It is structure. Cheap units are thin steel or polyester frames that you assemble yourself, and they are fine for burger nights but rarely survive more than a few British winters uncovered. Mid-range kitchens are usually aluminium or powder-coated steel with a worktop that will take heat. Bespoke kitchens are a garden building project in their own right, with footings, drainage, and a gas or electrician’s certificate at the end.

Outdoor Kitchen Cost UK by Type
The type of kitchen you choose is the single biggest driver of price. Here is how the common options compare.
| Factor | Modular / Flat-Pack | Custom Masonry Build |
|---|---|---|
| Typical cost | £700 – £12,000 | £15,000 – £40,000+ |
| Installation | DIY or light trades help | Builder, gas engineer, electrician |
| Lifespan | 5 – 15 years | 20+ years |
| Utilities | Usually none or electric only | Gas, water, drainage, power |
| Build time | 1 – 2 days | 2 – 6 weeks |
Modular kitchens win on upfront cost and speed. A masonry kitchen wins on permanence and resale appeal, and it is the only realistic option if you want a wood-fired oven, a sink with running water, or a built-in gas grill plumbed to the mains.
Prefab and Modular Kitchens
Prefab kitchens have improved enormously in the last decade. Brands like Grillo in the UK sell powder-coated steel units that look far more substantial than the old polyester rattan frames, typically from £3,000 to £8,000 once you add a gas grill and side burners. You pay for the weather resistance and the fact that the manufacturer has tested the units outdoors.
Bespoke Masonry Kitchens
A builder-built kitchen with blockwork, a rendered finish, and a stone or concrete worktop starts around £15,000. Add a pizza oven and you can lift that figure quickly – a proper wood-fired oven alone is often £2,000 to £5,000 installed. If that is on your wish list, our guide on pizza oven build costs in the UK sets out the numbers in detail.
What Drives the Outdoor Kitchen Cost UK Up
The headline price of a unit tells you very little. The final bill is made up of several parts, and three of them catch people out every time.
Groundwork and Decking
Your unit needs a level, stable base. On an existing patio you are fine, but laying a new paved area or reinforced concrete pad runs £80 to £150 per square metre. A raised deck that can take the weight costs more again. Skipping this step is how outdoor kitchens end up sinking at one corner within a year.
Utilities and Connections
This is the quiet budget killer.
- Electricity: running a dedicated outdoor circuit and weatherproof sockets costs £300 to £800, assuming your consumer unit can take it.
- Gas: a mains gas connection for a built-in grill legally requires a Gas Safe engineer, costing roughly £400 to £900 depending on the distance from the meter.
- Water and drainage: a sink with a plumbed supply and waste run adds £500 to £1,200.
If you do not want a plumbed sink, many homeowners use a covered worktop with a freestanding basin and a water container instead, which costs almost nothing and sidesteps the building work.
Materials and Worktops
Worktops matter more outdoors than indoors. Granite and slate handle heat and frost but run £180 to £350 per linear metre. Concrete looks great and is cheaper, starting around £100 per linear metre, but it can stain without sealing. Stainless steel is the pro kitchen choice and starts near £150 per linear metre. Cheap laminates are a false economy outside – UV light and moisture destroy them within a couple of summers.
Pizza Ovens and Grills: The Big-Ticket Add-Ons
The cooking equipment can cost more than the kitchen that holds it. A built-in gas grill from a brand like Napoleon or Bull starts around £1,000 and easily reaches £3,000 for a larger model. Pellet smokers sit in the £700 to £1,800 range.
Pizza ovens deserve their own line item. A portable gas oven costs £300 to £700 and works well enough for family use. A proper wood-fired oven, whether prefabricated or brick-built, is £1,500 to £5,000.

DIY vs Professional Installation
A flat-pack or prefab kitchen is genuinely DIY-able if you are comfortable with a drill and can level a slab. You will save the £500 to £1,500 a tradesperson charges to assemble, wire, and test the unit. The catch is that anything involving mains gas or a new electrical circuit is not a DIY job in the UK, and doing it yourself can void your home insurance.
Professional installation adds cost but buys compliance. A Gas Safe registered install and a Part P electrical certificate matter when you sell the house, and reviewers on home-improvement forums consistently flag unregistered gas work as the number one thing to avoid. For authoritative guidance on safe outdoor appliance installation, This Old House and Family Handyman both publish clear, practical walkthroughs that match UK practice closely.
How to Budget for an Outdoor Kitchen
A sensible order of operations keeps you out of trouble. Decide the cooking style first, the structure second, and the extras last.
- Set a hard budget before you browse. The biggest overspend comes from falling in love with a £6,000 kitchen when you planned for £2,500.
- Price the base first. Groundwork and utilities often cost as much as the unit itself.
- Buy the grill and oven separately where possible. Bundled packages are convenient but rarely cheaper than sourcing the components yourself.
- Build in phases. Buy the shell and a good grill this year, add a pizza oven or sink next year.
- Allow 10–15% contingency. Outdoor projects always surface a surprise, usually drainage.
On a per-area basis, an outdoor kitchen costs less than a comparable indoor kitchen extension, but the numbers add up fast. If you want a sense of how the price scales with size, our outdoor kitchen price per square foot breakdown walks through it.
Frequently Asked Questions
How much does an average outdoor kitchen cost in the UK?
Most UK homeowners spend between £4,000 and £15,000. A basic modular unit with a grill runs £3,000 to £6,000, while a bespoke masonry kitchen with utilities typically costs £15,000 to £40,000.
Do I need planning permission for an outdoor kitchen?
Usually not. An outdoor kitchen within your garden is classed as permitted development as long as it is not a permanent structure over 2.5 metres in height near a boundary. If you are adding a permanent roof or pergola, or your property is listed, check with your local planning authority first.
Can I build an outdoor kitchen myself?
Yes, for prefab and modular units. Anything involving mains gas, a new electrical circuit, or plumbing should be handled by a Gas Safe engineer or qualified electrician. Incorrect gas work is both dangerous and illegal in the UK.
What is the cheapest way to get an outdoor kitchen?
A flat-pack or freestanding prep station starts around £700, and a portable gas grill and pizza oven can be added later on an existing patio. Skipping a plumbed sink and running utilities is the easiest way to cut £1,000 or more from the bill.
Does an outdoor kitchen add value to a home?
A well-built outdoor kitchen can increase buyer appeal and, in some cases, add value, though it rarely returns the full cost. The real return is in daily use rather than a guaranteed uplift at sale.
The Bottom Line
The outdoor kitchen cost UK comes down to a simple rule: match the build to how you will actually use it. If you cook outside every weekend through summer, a mid-range modular kitchen with a proper grill and weatherproof worktops is the sweet spot at £5,000 to £12,000. If you want a garden centrepiece that will last for decades, budget £15,000 and up for a bespoke build.
Whatever you choose, spend on the base and the cooking equipment before you spend on looks, and never cut corners on gas or electrical work. Get the foundations right, hire registered trades for anything you cannot legally do yourself, and your outdoor kitchen will be the part of the house you use most between spring and autumn.
