How long does it take to remodel a house in the UK?

If you’re asking how long does it take to remodel a house, the honest answer is that UK renovation timings vary widely. A simple cosmetic refresh may take a few weeks, while a full-house remodel involving structural work can stretch to several months.

Because most UK homes are older and often require updates to wiring, insulation, drainage or layout, the timeline is shaped not just by the building work but also by planning rules, building control requirements and contractor availability.

Note: In the UK, “remodelling” is usually referred to as renovation or refurbishment. This guide uses both terms so homeowners searching either way get clear advice.

A good rule of thumb is:

  • Light refurb: 2–4 weeks
  • Medium renovation: 6–12 weeks
  • Full-house remodel: 3–9 months
  • Structural changes: Add 4–12 weeks

Next, we break this down stage-by-stage so you know exactly what to expect.

Key factors that affect renovation timelines

Although two homes may look similar, their timelines can be very different. Several factors influence how long a remodel takes:

  • Whether planning permission is required – Not all works are permitted development.
  • Building control approval – Most remodels require inspections and sign-off.
  • Structural changes – Removing walls or adding beams adds engineering and approval time.
  • Property age – Older homes may reveal hidden defects once walls/floors are opened.
  • Contractor availability – Good builders often have long lead times.
  • Material supply – Kitchens, windows and bespoke joinery all have varying delivery times.
  • Budget & decision-making speed – Delays approving quotes or designs push the schedule out.
Tip: The earlier you finalise drawings, structural calculations and specifications, the smoother the construction phase will be.

How long each stage of a house remodel takes

Here’s how long the main UK stages typically take, from initial ideas to completion.

1. Planning, drawings and design – 2–8 weeks

For most remodels, you’ll need some form of drawings—concept sketches or full measured plans. If the project also needs structural calculations or planning permission, allow longer.

For more detail, see our guide: Making Plans – Complete Guide to Costs & Approval.

2. Planning permission (if required) – 8 weeks

Not every remodel needs planning permission, but structural changes, extensions or layout changes often do.

If an application is needed, councils typically take 8 weeks for household planning decisions.

3. Building control approval – 2–8 weeks

Almost all remodels require building control. You can use either a Building Notice or a Full Plans application.

4. Contractor lead time – 2–12 weeks

Builders, electricians, plumbers and plasterers may need to be booked weeks in advance.

5. Construction – 2 weeks to 9 months

This is where timelines vary most. Light refurbishments move quickly. Full remodels involving structural work or reconfiguring layouts take far longer.

Renovation timeline table (UK averages)

Type of Work Typical Duration
Light cosmetic refurb (painting, flooring, small updates) 2–4 weeks
Kitchen or bathroom remodel 3–6 weeks
Medium renovation (rewiring, plastering, layout tweaks) 6–12 weeks
Full-house renovation (multiple rooms, services updated) 3–9 months
Structural changes (removing walls, RSJs, extensions) +4–12 weeks
Success tip: Ordering long-lead materials (kitchen, glazing, steelwork) early prevents downtime during construction.

Common delays during a remodel (and how to avoid them)

Even well-planned projects encounter surprises. These are the most common UK delays:

  • Hidden defects discovered after demolition (rot, old wiring, poor insulation).
  • Slow decision-making on finishes and fixtures.
  • Planning permission queries or additional information requests.
  • Structural engineer changes once site conditions are uncovered.
  • Trades availability gaps delaying handover between tasks.
Gotcha warning: Don’t start demolition before approvals are in place. This can risk enforcement action and void insurance.

Approvals, costs and lead times

Timelines often stretch because homeowners underestimate approval stages. Here are common timeframes:

  • Measured survey: 1–2 weeks
  • Architectural drawings: 2–8 weeks
  • Structural calculations: 1–3 weeks
  • Planning permission: 8 weeks
  • Building control plan check: 2–5 weeks

Frequently Asked Questions

Do I need planning permission to remodel a house?

Not always. Internal changes are often permitted development, but structural works, extensions or altering the roof shape usually require planning permission.

How long does it take to remodel an entire house?

Most full-house renovations take 3–9 months, depending on size, layout changes and materials.

Can you live in a house while it’s being remodelled?

Light works—yes. Major structural works—usually no, due to safety, dust and service interruptions.

When should I contact building control?

Before work starts. They will tell you when inspections are required and what they need to sign off your project.
