The London Commercial Construction Process

Timeline Expectations

Commercial build-outs in London typically follow this timeline:

  • Planning & Design (4-8 weeks): Space planning, architectural drawings, engineering
  • Permitting (3-8 weeks): Building department review and approval
  • Construction (8-20 weeks): Varies by size and complexity
  • Final Inspections (1-2 weeks): Certificate of occupancy

A standard 5,000 sqft office build-out takes approximately 4-6 months from design to move-in.

Choosing the Right Contractor

When evaluating contractors for your London project, consider:

  • Licensing & Insurance: Verify active licenses and adequate coverage
  • Specialty Experience: Has the contractor completed similar projects?
  • References: Speak with recent clients about their experience
  • Project Size Fit: Match contractor capacity to your project scope
  • Communication Style: Ensure alignment on reporting and updates

Frequently Asked Questions

Common questions about commercial renovation in London.

What is the average cost of a commercial build-out in London?
Commercial build-out costs in London typically range from $40-300+ per square foot depending on finish level and complexity. Basic cosmetic renovations run $40-80/sqft, standard tenant improvements cost $80-150/sqft, and high-end executive spaces can exceed $200-300/sqft. Factors like building age, MEP requirements, and permitting complexity significantly impact final costs.
How long does a typical commercial renovation take?
A standard 5,000 sqft office build-out takes 4-6 months from design to move-in. This includes 4-8 weeks for design, 3-8 weeks for permitting, and 8-16 weeks for construction. Larger or more complex projects can take 6-12 months. Fast-track schedules are possible at additional cost.
Do I need permits for my project?
Most commercial renovations require building permits. Cosmetic-only work (paint, carpet) may be exempt, but any structural, electrical, plumbing, or HVAC modifications require permits. Your contractor should handle the permit process, but budget 3-8 weeks and $5,000-50,000+ depending on project scope.
What's included in your RFP service?
Our RFP service includes professional scope of work documentation, distribution to 3-5 pre-qualified contractors in London, bid comparison analysis, and a dedicated project manager to guide you through selection. Most clients receive competitive proposals within 2 weeks.
What's the difference between Design & Build vs. Build Only?
Design & Build contractors handle both architectural design and construction under one contract, offering streamlined communication and often faster timelines. Build Only contractors work from plans provided by your architect or designer, which can offer more design flexibility but requires additional coordination.
