Opening a restaurant in London is rarely a quick project.
Many restaurant owners initially imagine that once they sign a lease, the interior design and construction will take only a few weeks. In reality, restaurant fit-outs involve approvals, engineering coordination and specialist construction that require careful planning.
Understanding the realistic timeline of a restaurant fit-out in London can help owners plan finances, staffing and opening dates more accurately.
While every project is different, most restaurant fit-outs typically follow a sequence of stages that take between 16 and 28 weeks from initial design to opening day.
1. Before Signing the Lease
Many experienced restaurant operators involve a design team before signing a lease.
At this stage the goal is to assess whether the space can realistically support a restaurant.
Important questions include:
Is there sufficient gas capacity? Can an extraction system reach the roof? Is the drainage system suitable for kitchen operations? Are structural modifications required?Will the landlord allow alterations?
Early feasibility advice can prevent major problems later.
2. Concept Design and Feasibility
Typical timeframe: 2–4 weeks
Once the space is secured, the first step is creating the concept and layout.
This stage includes:
initial interior concept development
dining layout and circulation planning
commercial kitchen layout coordination
early lighting and material direction
The objective is not only to define the look of the restaurant but also to ensure that the space works operationally for staff and guests. At this stage, potential technical challenges are also identified early.
3. Landlord Approvals and Licence to Alter
Typical timeframe: 3–6 weeks
Most restaurant tenants in London must obtain permission from the landlord before construction begins. Design drawings and technical proposals are submitted to the landlord’s surveyor for review.
These submissions typically include:
restaurant layout drawings
ventilation strategy
shopfront proposals
structural interventions
services coordination
Once approved, the landlord issues a Licence to Alter, which allows the tenant to begin construction works. Without this approval, construction cannot legally start.
4. Planning Permission and Regulatory Approvals
Typical timeframe: 4–8 weeks (where required)
Depending on the building and location, certain elements of a restaurant project may require planning permission.
This can include:
external signage
shopfront changes
visible extraction systems
listed building modifications
Restaurant projects also require coordination with building control and fire safety consultants.

5. Technical Design and Engineering Coordination
Typical timeframe: 2–4 weeks
Once approvals are underway, the project moves into detailed technical design. This stage converts the concept into a fully buildable project.
Typical technical work includes:
structural engineering coordination
mechanical, electrical and plumbing design
gas system planning and safety interlock systems
ventilation and extraction design
fire suppression systems for cooking equipment
lighting layouts and electrical distribution
Restaurant kitchens require particularly careful coordination because of their safety requirements and ventilation systems.
6. Construction and Restaurant Fit-Out
Typical timeframe: 8–12 weeks
Once drawings are finalised and approvals are secured, construction begins.
This phase typically includes:
structural works where required
ventilation and extraction installation
gas and electrical systems installation
drainage and plumbing works
flooring, wall finishes and ceiling construction
custom joinery such as bars and seating
commercial kitchen equipment installation
shopfront and signage installation
Restaurant construction requires careful sequencing of multiple trades working together.
For this reason, many projects are delivered through a design & build approach, where one team coordinates both design and construction.
7. Furniture, Equipment and Final Installation
Typical timeframe: 1–2 weeks
As construction nears completion, the project moves into final installation.
This stage typically includes:
furniture installation
bar equipment installation
kitchen appliances
lighting fixtures
decorative elements and finishing touches
The restaurant now begins to resemble the original design vision.
8. Testing, Certification and Handover
Typical timeframe: 1–2 weeks
Before opening, several systems must be tested and certified.
These may include:
electrical certification
gas safety certification
fire alarm commissioning
ventilation testing
building control inspection
Once these checks are complete, the restaurant is ready for handover. At this point the owner can begin staff training and prepare for opening day.
Typical Restaurant Fit-Out Timeline in London
While every project is different, a realistic schedule often looks like this:
Concept design 2–4 weeks
Landlord approvals 3–6 weeks
Planning permissions (if required) 4–8 weeks
Technical design 2–4 weeks
Construction and fit-out 16–28 weeks
Final commissioning 1–2 weeks
In total, most restaurant projects take approximately 16–28 weeks from the first day of the execution to opening.
Why Early Coordination Matters
Restaurant projects involve far more than interior decoration.
They combine architecture, engineering systems, compliance approvals and specialised hospitality equipment. Without careful coordination, small delays in approvals or technical design can quickly extend the project timeline.
This is why many restaurant owners choose to work with a design & build team that manages the entire process from concept design to final handover.
