A realistic guide for restaurant owners
Opening a restaurant in London is rarely just an interior design project.It is a technical construction programme involving approvals, engineering systems, kitchen integration and strict safety compliance — all delivered on a deadline.Many restaurant owners first search online for a simple answer: How much does a restaurant fit-out cost in London?
The reality is that costs vary significantly depending on the space, the building condition and the complexity of the project. But there are realistic ranges — and understanding what actually goes into a restaurant fit-out helps explain those numbers.
Realistic Restaurant Fit-Out Costs in London
For a full design & build restaurant project in London, typical budgets today fall roughly within these ranges:
Small takeaway or neighbourhood restaurant£350,000 – £450,000
Mid-size restaurant£450,000 – £800,000
High-end restaurant or complex hospitality concept£800,000 – £1.5M+
These figures usually include design, approvals, construction, electical & plumbing & gas services systems, bespoke joinery, commercial kitchen, HVAC's and final installation of all decors and furnitures.
The reason costs reach these levels becomes clearer once you understand what a restaurant project actually involves.
What Actually Goes Into a Restaurant Fit-Out
A restaurant interior is not simply decoration. It is a combination of architecture, engineering, compliance and specialised construction. A typical London restaurant project may include:
Concept design and interior architecture
Commercial kitchen layout and coordination
Fire consultation and fire risk assessment
Building control appointment
Planning permission submissions
Extraction and ventilation system design
Gas supply and safety systems
Water and drainage coordination
Electrical and three-phase power installation
Fire suppression systems for cooking areas
Emergency lighting and fire alarms
CCTV and security systems
Structural works where required
Ceiling, flooring and partition construction
Bespoke bar counters and seating
Custom joinery and furniture production
Shopfront design and signage approvals
Commercial kitchen equipment integration
Furniture, fixtures and equipment procurement
Each of these components requires specialist coordination — and most of them must be approved before construction can begin.
In older London buildings, additional surveys such as asbestos surveys and drainage inspections are often required before work starts.
Why Restaurant Projects Are Complex
Many restaurant spaces in London begin as empty shell units or converted retail spaces.
Before opening day, the project may require:
Landlord approvalsLicence to Alter agreementsPlanning permissionsBuilding control submissionsFire strategy reviewStructural engineer coordination
Without careful planning, these steps can delay a project for months.
This is why many restaurant owners choose to work with a design & build team that coordinates the entire process under one responsibility.
What a Full Restaurant Fit-Out Actually Includes
When people first hear the cost of a restaurant fit-out in London, the number can seem high.
But what many first-time restaurant owners don’t realise is that a professional design & build project covers far more than interior decoration. It includes every technical, regulatory and construction step required to turn an empty unit into a fully operational restaurant.
By the time the project is completed, the space is not simply “designed”.It is ready to operate.
The kitchen systems are installed and tested.The ventilation and gas systems are certified.The electrical systems and fire alarms are commissioned.The building control process is closed.
The furniture, lighting and bespoke joinery are installed.The bar is operational.The kitchen equipment is integrated.
At that point, the owner’s role is simple:
Bring the staff.Bring the menu.Start training the team.
The restaurant is ready to open.
This is what a true design & build project means — a fully coordinated process where design, approvals, engineering systems and construction are delivered by one responsible team.
At Kapeti, this approach allows restaurant owners to focus on their concept and their business while we coordinate every technical and construction detail behind the scenes.
In a traditional setup, restaurant owners must coordinate:
an interior designera contractorengineerskitchen suppliersconsultantsand local authorities
A design & build approach integrates these responsibilities.
At Kapeti, projects are managed by one team from concept design through construction and final handover. Interior architecture, technical coordination and construction planning happen together rather than as separate stages.
This reduces delays, avoids redesign during construction and ensures the final space matches the original design vision.
Why Early Planning Matters
One of the most common mistakes restaurant owners make is speaking to designers or contractors too late in the process.
Many clients approach Kapeti after already signing a lease — only to discover technical challenges that affect cost and timelines.
Ideally, a design & build team should be involved before the lease is signed, helping assess:
whether the space is viable for a restaurantwhat the realistic fit-out budget will behow long the project will takewhat approvals will be required
This early guidance often saves significant time and cost later.

Final Thoughts
Restaurant fit-out costs in London can seem high when seen as a single number.
