Outdoor Kitchen Installations: Planning Permission, Cost Considerations, and Design Expertise
Creating an outdoor kitchen can transform how you use your garden. It brings cooking, dining, and entertaining into the landscape in a way that feels effortless and refined. If you are in the UK, a clear plan is essential, especially around permissions, budgets, and build quality. This guide outlines what you need to know, and how accredited professionals ensure the result is both compliant and long lasting.

Do you need planning permission for an outdoor kitchen in the UK?
In many cases, no. A simple outdoor kitchen is often treated as permitted development when it is a modest, ground level installation with no raised platforms over 30 cm, and no structures that count as outbuildings or extensions.
However, permission can be required in certain circumstances. Check the following before you begin:

Location and design
​Installations within the curtilage of listed buildings usually require consent.Properties in conservation areas, National Parks, Areas of Outstanding Natural Beauty, or the Broads have tighter controls. Flued appliances, extraction chimneys, and tall pergolas may trigger permission.

Height and massing
Tall canopies, permanent roofing, or walls can change classification from freestanding furniture to a structure.
Raised terraces or decks over 30 cm may require permission.

Services and safety
Gas, electricity, and water must comply with Building Regulations even if planning permission is not needed.
Drainage, wastewater, and any new external doors or openings into the house will need assessment.

Boundaries and neighbours
Smoke from grills, odour control, and distances to boundaries can be questioned by planning case officers or Environmental Health where disturbance occurs.

Best practice
Obtain written confirmation from your Local Planning Authority if you are unsure.
Keep installations low and open, with minimal fixed roofing.
Use certified trades for gas and electrics, and retain certificates.
Document layouts, heights, and distances. This speeds up enquiries and avoids delays.

Miller’s Garden Services can prepare scaled plans and advise on whether the proposal likely falls under permitted development. Formal planning submissions can also be managed where required.

What is the cheapest way to create an outdoor kitchen?

You can achieve a functional, attractive setup on a sensible budget by focusing on core elements and materials that perform well outdoors without excessive costs.

Cost saving principles

Start with the essentials
A quality freestanding gas or charcoal grill.
A compact, weather resistant preparation surface.
Safe, level, non-combustible base.

Choose modular, not bespoke
Prefabricated modules reduce fabrication time and wastage.
Add modules later, such as drawers, fridge, sink, or pizza oven, as budget allows.

Value materials
Concrete blocks with a rendered finish, porcelain paving offcuts for worktops, or compact laminate designed for exteriors.
Avoid soft woods around heat, and avoid low grade steels that rust quickly.

Keep services simple
Cold water via an external tap and a jerry can for waste is cheaper than connecting to mains drainage.
Low voltage outdoor rated electrics with protective devices, installed by a qualified electrician.

Prioritise shelter solutions that do not count as permanent structures
A quality cantilever parasol or sail shade can be more cost effective than a roofed pergola.

Plan for storage and weathering
Use covers, vented cabinets, and correct clearances around burners. It extends lifespan and reduces replacement costs.

A good baseline budget for a simple, freestanding setup can start from several hundred pounds for equipment, with installation and a safe hardstanding taking the total into the low thousands. A well-planned foundation and utilities layout will allow upgrades later without rework.

Is it cheaper to build your own outdoor kitchen?
Self-build can appear cheaper if you are comfortable with masonry and joinery, but the true answer depends on risk, compliance, and finish quality.

Consider
DIY advantages
Savings on labour where skills are strong.
Full control over layout and materials.

DIY risks
Incorrect ventilation around gas appliances can be dangerous.
Poor detailing leads to water ingress, swelling, corrosion, and shorter lifespan.
Non-compliant electrics or gas void insurance and warranties.

Professional advantages
Correct clearances, thermal breaks, and fire-safe materials.
Integration of drainage falls, frost protection, and service routes.
Durable, low-maintenance finishes that look cohesive with the wider garden.
Manufacturer warranties when installed by approved partners.

In many projects, a hybrid route is most cost effective. Let professionals handle the design, foundations, utilities, and appliance integration. You can undertake landscaping touches or simple finishes. This approach controls risk, keeps standards high, and still reduces total spend.

Typical budget ranges in the UK

Costs vary by scope, location, and choice of appliances:

Entry level
Quality freestanding grill, compact prep area, simple storage, safe base.
From low thousands including basic groundworks and electrics.

Mid-range modular
Branded modular units, porcelain or composite worktops, integrated sink, fridge, task lighting.
From several thousands into the teens for a cohesive, durable setup.

Premium bespoke
Built masonry or steel frames, high specification appliances, extraction, architectural shading, integrated seating and lighting.
From the high teens upward, aligned with broader landscaping enhancements.

Investing in the base, drainage falls, and utilities first always pays back. Appliances can be upgraded later without undoing core works.

Design recommendations that stand the test of time
A considered layout raises safety, comfort, and longevity.

Zoning
Separate hot, wet, and cold zones with adequate prep space between.
Keep grills leeward of prevailing winds to reduce smoke drift.

Clearances and ventilation
Follow appliance manuals on side and rear gaps.
Vent low and high within cabinets to prevent gas build up.

Surfaces and structure
Use non-porous, frost-resistant materials.
Detail drips and overhangs to shed water.

Lighting and power
Task lighting over prep areas, low level path lighting for steps.
Outdoor rated sockets with RCD protection.

Drainage and cleaning
Gentle falls away from the house, easy access for hose down.
Removable panels for maintenance and winterisation.

Integration with the garden
Match paving modules and tones for a seamless look.
Plant aromatic, heat tolerant herbs nearby, avoiding resinous plants close to flame.

Why choose accredited professionals
Professional oversight avoids common pitfalls and protects your investment.

Compliance
Building Regulations for gas and electrics, certificates retained for insurance.

Durability
Details that resist frost, UV, and moisture cycles.

Cohesion
The kitchen sits comfortably within the wider design, paths and seating are resolved, and sightlines are preserved.

Accountability
Clear quotes, timelines, and warranties.
