Beginner’s Guide to Building an Outdoor Kitchen in the UK: Costs, Materials and Layouts

  • October 05, 2026

An outdoor kitchen usually starts with one small thought: a proper grill, somewhere to set down a plate, a worktop that isn't the windowsill. Then you find yourself sketching brick slips on the back of an envelope. It's one of the few home improvements you'll use every week through summer, and plenty of times in spring and autumn too if you plan a bit of shelter.

You don't need a big garden or a big budget to get this right. You need a clear idea of how you actually cook, materials that can handle a British winter, and a layout that doesn't send you walking around an island to reach the sink.

Decide how you'll cook before you spend anything

Two questions shape the whole project: how much cooking capacity you need, and how many people you want to seat.

Most first builds get this backwards. People plan for twenty guests and end up with nowhere to chop an onion. Picture a normal Saturday instead. You're cooking for four, someone is carrying things out from the kitchen, and there's a bowl of marinade with nowhere sensible to sit. Design for that scene. Big occasions are a bonus.

Write down the jobs your outdoor kitchen has to do — grill, side dish, prep, cold drinks, somewhere for plates — then rank them. Anything in the bottom half can wait for phase two.

Budgeting: where the money really goes

Costs split into four buckets, and the last one catches people out:

  • Base and structure — footing, frame, cladding, brickwork or timber.
  • Countertop — often the largest single line item.
  • Appliances — grill, side burner, fridge, sink, storage.
  • Services — electrics, gas, water and drainage, plus the trenching to reach them.

Services are the most underestimated. Getting power and water to the far end of a garden means digging, ducting and a qualified tradesperson, and it is far cheaper to do while the ground is open than to lift a finished base later. Settle the final footprint and run the services to suit it, even if the grill itself arrives next year.

Get three quotes from local trades and ask what's excluded — skip hire, waste removal, making good the lawn. Mention any narrow side return up front, because it affects how materials arrive and how much labour is involved. Keep a contingency: old paving, tree roots and forgotten drains all have a habit of appearing once you start digging.

Countertops that cope with British weather

The worktop takes the worst of it — frost, rain, sun and hot pans. The practical options:

  • Porcelain or ceramic — UV-stable, frost-resistant and almost non-porous. Needs full support underneath and a skilled cutter.
  • Granite — hard, heat-tolerant and often available as offcuts. Heavy, needs occasional sealing, and slippery when wet.
  • Engineered quartz — lovely indoors, but many manufacturers won't warrant it outdoors because UV can affect the resin. Check before you buy.
  • Concrete — can be cast to any shape. It will crack without proper reinforcement and joints, and it needs resealing every year or two.
  • Timber — iroko, teak or sapele are the durable choices. Warm, easy to work, but they need oiling and they will mark.
  • Stainless steel — hygienic and unfazed by hot pans. It scratches, and it gets uncomfortably hot in direct sun.

Whichever you choose, ask the supplier in writing whether it's rated for permanent outdoor use in a UK climate, and how it behaves with frost and UV. Two rules apply to all of them: support the top along its length rather than relying on the edges, and give it a slight fall so water runs off instead of pooling in the corners.

Choosing your cooking appliances

Start with the grill, because it dictates everything else. A built-in gas grill gives fast, repeatable heat and a lid you can close. Charcoal gives you smoke and flavour, but more hands-on time and somewhere to put the ash. Kamado cookers are fuel-efficient and excellent for long cooks, though they're heavy and need a cover. Pellet grills are easy to run but need power. A flat-top plancha earns its space quickly if you like breakfasts and fried rice.

After the grill, most people add a side burner, then a sink, then a fridge. Two notes: an outdoor-rated fridge is built to cope with temperature swings and a standard indoor one isn't, and you should never box an appliance into a cavity without following the manufacturer's clearance and ventilation figures. Grills need airflow, and a sealed cupboard becomes an oven.

Layouts that work in real gardens

Ignore the showroom islands for a moment and think about walking. The aim is a short, comfortable triangle between the grill, the prep surface and the sink or bin, with somewhere to put a hot tray.

The single run

The workhorse for narrow gardens and side returns. Two to three metres gives you a grill, a decent stretch of prep space and a cupboard or two. Put it against a wall or fence and leave at least a
