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.
How long does it really take to open a restaurant in London in 2026?
From lease signature to opening night: 20 to 48 weeks depending on premises complexity, planning route, licence timeline and specification. Small high-street venues at the lower end; mid-size premium venues 28-36 weeks; signature and heritage-building venues 40+ weeks.
Most first-time operators think the fit-out is the long part. In reality, the design, planning permission, licence to alter and premises licence work is typically longer than the construction itself — and it must be sequenced properly or the fit-out cannot start.
This guide is the honest week-by-week reality. What each phase involves, what actually consumes time, where operators most consistently underestimate, and what a design-build firm does differently to compress the programme without cutting corners.

WHO THIS GUIDE IS WRITTEN FOR
First-time restaurateurs planning realistic timelines to raise capital or brief investors
Hospitality operators expanding into London who need programme certainty for staffing and marketing
Investors evaluating restaurant business plans and needing to sanity-check timeline assumptions
Anyone who has been told "12 weeks fit-out" by a contractor and wants to understand what is actually true
The next 12 minutes will save you from the two most expensive timing mistakes in London restaurant investment: launching pre-opening marketing before you can open, and staffing up before the space is ready.

1. THE HONEST HEADLINE TIMELINE FOR 2026
Realistic 2026 programmes from lease signature to opening day, in central and inner London:
Restaurant Type | Programme Range | Typical |
Small casual (up to 60 covers, existing restaurant use) | 20-28 weeks | 24 weeks |
Mid-size neighbourhood (80-120 covers, change of use) | 26-36 weeks | 30 weeks |
Premium restaurant (100-150 covers, standard building) | 30-40 weeks | 34 weeks |
Signature venue (150+ covers, complex fit-out) | 36-48 weeks | 40 weeks |
Heritage / listed building (any size) | 40-56 weeks | 46 weeks |
Central London mansion block ground floor | Add 4-8 weeks | Building restrictions |
The fit-out construction itself is typically only 10-22 weeks of the total programme. Everything else is design, consents and pre-opening.
The two most consistently underestimated categories:
The front-end — design, planning, licensing, landlord approvals. Operators expect 6-8 weeks. Reality is 10-16 weeks for anything meaningful.
Pre-opening — commissioning, snagging, staff training, soft launch. Operators expect 2 weeks. Reality is 4-8 weeks.
Rule of thumb: total programme from lease to opening = fit-out construction × 2.2 to 2.6.

2. PHASE 1 — CONCEPT AND FEASIBILITY (WEEKS 1-4)
What happens: The professional team is appointed. Detailed premises surveys are commissioned. Concept brief is developed and tested against operational reality.
Key activities:
Structural survey (walls, floors, ceilings)
MEP survey (extraction capability, gas supply, electrical capacity, drainage)
Acoustic survey (neighbours, party walls)
Fire strategy consultation
Concept design brief — cover count, service model, brand, price point
Kitchen operational output planning
Preliminary cost benchmarking
Common mistake: Skipping the survey stage to save 3-4 weeks. This is where fatal discoveries — inadequate extraction, missing gas supply, drainage problems, structural constraints — are caught. Discovering these during construction costs 5-10 times more than discovering them in feasibility.
Time consumed: 3-4 weeks for surveys plus concept development.
3. PHASE 2 — DETAILED DESIGN AND CONSENTS (WEEKS 3-14)
What happens: Concept becomes buildable design. All technical disciplines are coordinated. Consent applications are prepared and submitted.
Key activities:
Interior design development
Kitchen design and equipment specification
MEP design (mechanical, electrical, plumbing)
Fire strategy documentation
Structural design if alterations required
Acoustic strategy
Landlord drawings for Licence to Alter
Planning permission drawings if required
Premises licence application
Building Control application
In design-build: All of this runs in parallel under one team, with one project manager coordinating. Design decisions and construction feasibility are aligned from the start.
In traditional procurement: Designer produces drawings, then contractor tender takes 4-8 weeks, then contractor reviews design and identifies issues, then designer revises, then re-tender. This cycle adds 6-12 weeks to the same scope.
Time consumed: 8-12 weeks in design-build, 12-18 weeks in traditional procurement.
4. PHASE 3 — PLANNING PERMISSION (WEEKS 4-16)
When required: Change of use (e.g. retail to restaurant), external alterations, extensions, change of hours beyond permitted, listed building work.
When not required: Restaurant-to-restaurant same-use conversions with no external work.
Typical timeline:
Straightforward application, no objections: 8-13 weeks
Contested application with objections: 4-6 months
Listed building consent: 8-16 weeks (parallel to planning)
Conservation area constraints: adds 2-4 weeks
Key drivers of delay:
Objections from residential neighbours (noise, extraction, delivery vehicles, hours)
Objections from environmental health (extraction routing, ventilation)
Requests for additional information or amendments
Committee decisions (larger or contested applications)
How to compress: Pre-application discussions with the local authority before formal submission. This adds 2-4 weeks upfront but often halves the formal decision period and dramatically reduces objection risk.
Non-compressible: The 8-week statutory period for a standard application. This cannot be shortcut.
5. PHASE 4 — PREMISES LICENCE (WEEKS 6-14)
Required for: Almost all restaurants selling alcohol, providing late-night refreshment (past 11pm), or hosting regulated entertainment.
Typical timeline:
Straightforward application, no objections: 4-8 weeks
Application with objections or hearing: 10-14 weeks
Complex application (late-night, entertainment, contested location): 12-18 weeks
Key activities:
Application drafting (operating hours, activities, conditions)
Consultation period (28 days statutory)
Consultation with police, licensing officers, environmental health
Public notice display and press notice
Hearing if objections received
How to compress: Engage a specialist hospitality licensing solicitor from day one. Draft the application to minimise objection risk. Consult informally with the licensing authority before formal submission.
Non-compressible: The 28-day statutory consultation period. This cannot be shortcut.
6. PHASE 5 — LICENCE TO ALTER AND LANDLORD APPROVALS (WEEKS 8-16)
Required for: Almost all leased premises. Structural, MEP or services alterations trigger Licence to Alter.
Typical timeline:
Straightforward building, professional landlord: 4-8 weeks
Managed building with detailed surveyor review: 6-12 weeks
Mansion block or complex building: 10-16 weeks
Central London prime buildings (Mayfair, Knightsbridge, Chelsea): often at the longer end
Key activities:
Detailed drawings submitted to landlord's surveyor
Structural engineer sign-off
MEP schedules
Contractor insurance and CDM documentation
Landlord surveyor review and comments
Amendments if requested
Licence granted with conditions
Cost: £3,000-£15,000 in landlord's surveyor and legal fees, paid by tenant.
How to compress: Start Licence to Alter application immediately after lease signature. Do not wait for design to be complete — submit preliminary drawings early and refine through the process.
Non-compressible: Landlord's surveyor's review time. Cannot be pushed by tenant urgency.
7. PHASE 6 — CONSTRUCTION AND FIT-OUT (WEEKS 14-30)
What happens: Physical construction. This is what most operators think of when they think "fit-out."
Realistic 2026 construction programmes:
Small casual restaurant (existing use, standard building): 10-14 weeks
Mid-size neighbourhood: 14-18 weeks
Premium restaurant: 16-22 weeks
Signature / listed: 20-30 weeks
Typical week-by-week structure for a mid-size restaurant (16 weeks on site):
Weeks 1-2: Strip-out, structural preparation, service enabling works
Weeks 3-6: Structural works, MEP first-fix (electrical, plumbing, ventilation ductwork)
Weeks 5-9: Partitioning, wall build-up, ceiling grid
Weeks 7-11: Kitchen infrastructure (extraction, gas, drainage), joinery installation begins
Weeks 9-13: MEP second-fix, joinery continues, flooring
Weeks 11-14: Kitchen equipment installation, bar installation, decoration
Weeks 13-15: FF&E installation, commissioning
Weeks 15-16: Snagging, deep clean, handover preparation
Where programmes slip during construction:
Landlord out-of-hours restrictions in mansion blocks
Late kitchen equipment specification changes (each change: 2-4 weeks)
Provisional sum resolutions higher than budgeted
Discovery of hidden building conditions during strip-out
Weather-related delays for external work
Unavailability of specialist trades at short notice
Where design-build shortens construction:
Bespoke joinery manufactured in parallel with construction (not sequential)
Kitchen equipment ordered from concept stage (not after construction starts)
No design-contractor coordination gaps
Single team decision-making for on-site variations
8. PHASE 7 — KITCHEN COMMISSIONING AND PRE-OPENING (WEEKS 28-38)
What happens: The physical space is complete. Now it needs to be commissioned as an operating business.
Key activities:
Kitchen equipment installation and commissioning
Gas commissioning and certification
Electrical certification
Fire alarm and life safety commissioning
Building Control final inspection and closure certificate
Environmental health inspection
Food business registration (28 days notice minimum)
Premises licence granted and activated
POS, booking system, IT setup and testing
Staff hire and pre-opening training
Menu development and tasting
Photography and marketing content
Time consumed: 4-8 weeks. Often runs partly parallel with final construction phase.
Where operators most consistently underestimate:
Staff training. Front-of-house needs 2-3 weeks minimum, kitchen team similar. Rushed training produces poor first-month service and damages reviews at the most critical moment.
Certifications and inspections. Cannot be rushed. Each has its own timeline.
Menu development and food photography. Rarely completed in the timeline originally planned.
9. PHASE 8 — SOFT LAUNCH AND OPENING (WEEKS 36-42)
What happens: Restaurant opens at reduced capacity for testing before public opening.
Typical structure:
Week 1 of soft launch: Staff and family only, testing all systems
Week 2 of soft launch: Friends of house, industry contacts, limited public bookings at reduced covers
Week 3: Reviews trades and press previews begin
Week 4: Full public opening
Why soft launch matters: Restaurants that skip soft launch consistently open with operational problems that damage reviews. The first month of reviews sets the trajectory for the first year of trading. £15,000-£30,000 of "lost revenue" during soft launch is trivial compared to the cost of poor reviews at full opening.
Marketing sequencing: PR and social media activity should build during the last 4-6 weeks of construction, peak at opening, and continue for 8-12 weeks after opening.
10. WHERE OPERATORS MOST CONSISTENTLY LOSE TIME
Six patterns we see repeatedly:
1. Signing the lease before the survey is complete. The lease is a 10-15 year commitment. Signing before knowing whether the extraction can be routed, the gas supply exists, or the drainage supports a commercial kitchen is a genuine business risk. 3-4 weeks of pre-lease survey saves months of remedial work later.
2. Starting design without appointing the full team. Interior design without kitchen input, without MEP coordination, without fire strategy input produces a design that changes fundamentally when the other disciplines get involved. Each change cycle adds 2-6 weeks.
3. Waiting for planning permission before starting Licence to Alter. These run in parallel. Sequential handling adds 6-12 weeks. Both should be initiated as soon as the lease is signed and design is sufficiently developed.
4. Late specification changes. Menu change, service model change, kitchen equipment change, brand direction change — each affects design, procurement and construction. Late changes cost multiples of early changes.
5. Under-resourced pre-opening. The last 4-8 weeks before opening need dedicated project management, not just contractor supervision. Handover is a discipline, not an event.
6. Compressing programme to hit an arbitrary opening date. Programme compression costs 10-25% in overtime, accelerated procurement and premium-rate trades. Sometimes worth paying (hard external deadlines). Often not.
11. HOW DESIGN-BUILD COMPRESSES THE PROGRAMME
The most consistent programme advantage of design-build over traditional procurement is not a single time saving — it is the elimination of coordination cycles.
Where design-build compresses time:
Design and construction feasibility are aligned from day one (no design-then-tender cycle)
Bespoke joinery ordered from concept stage (not after design freeze)
Kitchen equipment specified with construction team input (not thrown over the fence)
MEP coordination internal to the team (not between separate designer and contractor)
Site variations decided in hours, not weeks
Single team accountable for programme (not two parties blaming each other)
Typical programme saving vs traditional procurement: 4-10 weeks on a mid-size restaurant project. On a 30-week programme, that is 15-30% programme reduction — plus the cost saving of not paying for coordination overhead.
This is how Kapeti operates on restaurant projects — design, build, kitchen coordination, joinery, FF&E procurement, project management, all under one contract, one team, one accountable party. It is why our restaurant projects consistently open on programme when the market average is 4-8 weeks late.

12. FREQUENTLY ASKED QUESTIONS
How long does a restaurant fit-out take in London?
From lease signature to opening: 20-48 weeks depending on complexity. The physical construction is typically 10-22 weeks; design, planning, licensing and pre-opening make up the rest. A mid-size neighbourhood restaurant typically opens 28-36 weeks after lease signature.
Can I open a restaurant in London in 3 months?
Only in very specific circumstances: an existing restaurant premises with a live premises licence, no change of use required, straightforward building, minimal alterations. Even then, 12 weeks is compressed and expensive. Most restaurants realistically take 6-9 months minimum from lease to opening.
How long does planning permission take for a restaurant?
Straightforward planning application: 8-13 weeks. Contested applications with objections: 4-6 months. Listed building consent: 8-16 weeks. Change of use applications (retail to restaurant): 8-13 weeks typical. Not required for restaurant-to-restaurant same-use conversions.
How long does a premises licence take in London?
4-8 weeks for a straightforward application. 10-14 weeks if there are objections and a hearing. The 28-day statutory consultation period cannot be shortcut. Complex applications (late-night, entertainment, contested residential locations) can extend to 12-18 weeks.
What is a Licence to Alter and how long does it take?
Consent from the freeholder to make structural, MEP or services alterations. Most leased premises require it. Timeline: 4-16 weeks depending on building and landlord complexity. Central London prime buildings often at the longer end. Costs £3,000-£15,000 in landlord's surveyor and legal fees.
Why do restaurant fit-outs take longer than office fit-outs?
Four reasons: (1) kitchen coordination adds specialist scope not present in offices; (2) extraction and gas commissioning are complex and time-consuming; (3) premises licence process runs in parallel; (4) FF&E for restaurants (bespoke banquettes, bar joinery, specialist lighting) has longer lead times than typical office FF&E.
Can I compress the fit-out programme?
Some phases can be compressed, at cost. Construction can be accelerated 15-25% at 10-25% cost premium (overtime, accelerated procurement). Statutory periods (planning consultation, licence consultation) cannot be compressed. Design and licensing can be run more aggressively in parallel with proper coordination.
What happens if the fit-out overruns?
Every week of delay is: rent paid without revenue, staff hired without trading, marketing spent without opening, investor confidence eroded. On a mid-size London restaurant, each week of delay costs £8,000-£25,000 in direct rent-plus-staff cost alone, before considering revenue impact.
How does design-build compare to traditional procurement on programme?
Design-build typically delivers restaurants 4-10 weeks faster than traditional procurement on the same scope. Saving comes from eliminated coordination cycles, parallel manufacturing of bespoke items, and single-team decision-making on site.
When should I start pre-opening marketing?
PR activity should build in the last 6-8 weeks of construction. Social media and content marketing should start in the last 12-16 weeks. Bookings platform integration and reservations should open 4-6 weeks before opening. Anything earlier and you damage credibility if the programme slips.
What is the biggest reason restaurant fit-outs run late?
Consistently: late-stage specification changes. Kitchen equipment changed after order, layout revised after construction started, brand direction shifted after joinery ordered. Each change cascades. Decisions made properly at design stage and held through delivery is the single most reliable programme protection.
Can Kapeti deliver a restaurant fit-out on a fixed programme?
Yes. We agree a fixed programme at contract signature and manage to it. Our restaurant projects consistently deliver on programme because design, procurement, coordination and construction are all handled by one team under one contract. This is what design-build under one contract genuinely delivers.
