How Long Does It Take to Renovate a House in London?

Renovating a house in London can be an exciting yet daunting project. Whether you’re modernising a Victorian terrace, refreshing a flat, or completely overhauling a townhouse, the big question many homeowners ask is: how long will it take?

The answer depends on several factors—size, scope, property age, and even local regulations. Below, we break down the typical timelines.

Factors That Affect Renovation Timelines

1. Scope of Work

   • Cosmetic updates (painting, flooring, fixtures) can take just a few weeks.

   • Structural renovations (removing walls, extensions, loft conversions) can take several months.

   • Full refurbishments (rewiring, plumbing, layout changes) may last 6–12 months.

2. Planning and PermissionsIn London, planning permission and listed building consent can add weeks—or even months—before work begins. Conservation areas require special approvals, which extend timelines.

3. Property Type and AgeOlder properties often hide surprises: outdated wiring, damp, or structural issues. These can delay completion compared to newer builds.

4. Contractor AvailabilitySkilled tradespeople are in high demand in London. Scheduling the right team can affect how quickly the project progresses.

5. Budget and Supply ChainMaterial delays, especially for bespoke fittings or imported items, can extend your timeline.

Typical Timelines in London

• Small-scale renovations (4–8 weeks): Painting, new floors, kitchen or bathroom updates.

• Medium-scale projects (3–6 months): Loft conversions, single-storey extensions, or major kitchen refits.

• Full house refurbishments (6–12 months): Gutting interiors, updating plumbing and electrics, layout changes, and extensions.

Tips to Stay on Schedule

• Plan ahead: Secure permissions early and order materials in advance.

• Hire experienced professionals: A London-based contractor familiar with local rules will save you time.

• Expect the unexpected: Always factor in contingency time (10–20% of the project length).

• Stay flexible: Weather, supply chain delays, and unforeseen issues are common in London renovations.

On average, a full house renovation in London takes between 6–12 months, but smaller projects can be completed in weeks. The key is understanding your project scope, planning effectively, and working with reliable professionals. With the right preparation, you can transform your property without unnecessary delays.
