If you’re planning a full house renovation in London in 2026, one of the first questions you’ll ask is: How much will it cost? Renovation prices in London vary depending on property size, scope of work, materials, and structural complexity. However, understanding realistic budget ranges can help you plan confidently and avoid costly surprises.

In 2026, the average cost of a full house renovation in London typically ranges between £1,500 and £3,500 per square metre. For a standard three-bedroom home, total renovation costs may fall between £80,000 and £180,000+, depending on the level of finish and whether structural changes are required.

What Impacts Renovation Costs in London?

London renovation costs are generally higher than the UK average due to labour rates, material costs, property access, and borough regulations. Here are the main factors that influence your total budget:

1. Property Size & Condition
Larger properties naturally cost more to renovate. Older Victorian or Edwardian homes may require rewiring, replumbing, damp proofing, or structural reinforcement, which increases costs.

2. Structural Work
Removing load-bearing walls, installing RSJs, underpinning, loft conversions, or rear extensions can significantly increase your budget. Structural alterations often require structural engineers and building control approvals.

3. Kitchen & Bathroom Renovations
Kitchens and bathrooms are typically the most expensive rooms to renovate. A mid-range London kitchen renovation may cost between £15,000 and £35,000, while a bathroom renovation can range from £8,000 to £20,000 depending on specification.

4. Finishes & Materials
High-end finishes such as bespoke joinery, natural stone worktops, underfloor heating, and premium flooring will increase your overall investment. Choosing quality materials can improve durability and long-term value.

5. Labour & Project Management
Hiring experienced builders, electricians, plumbers, and decorators ensures compliance and quality workmanship. Using one renovation company that manages the entire project can reduce delays and coordination issues.

Is Renovating Worth It in London?

In many London boroughs, a well-executed full renovation can significantly increase property value. Upgraded kitchens, modern bathrooms, improved energy efficiency, and open-plan layouts are highly desirable among buyers. Renovating can also be more cost-effective than moving, especially when factoring in stamp duty and legal fees.
