24 Jun How Much Does a Property Refurbishment Cost in London? Complete 2026 Cost Guide
One of the most common questions we hear from homeowners is: how much does a property refurbishment cost in London? Whether you are planning a light refurbishment, a full house refurbishment, or a major structural renovation, understanding the likely costs before you begin is essential.
London has some of the highest construction and labour costs in the UK, which means house renovation costs can vary significantly depending on the property type, specification, and project complexity. A simple internal renovation may cost tens of thousands of pounds, while a full house renovation involving structural work and premium finishes can exceed £250,000.
With more than 15 years of experience delivering refurbishment and renovation projects across London, we have helped homeowners transform properties ranging from modern apartments to period family homes. In this guide, we break down the average cost ranges, explain the factors affecting renovation costs, and show how to save money without compromising quality.
Average House Renovation Cost in London
The average house renovation cost depends on the size of the property and the scope of work involved.
As a general guide, the cost to renovate a house in London typically falls within the following ranges:
| Type of Renovation | Average Cost Per Square Metre |
| Light Refurbishment | £750 to £1,250 |
| Internal Renovation | £1,250 to £2,000 |
| Full House Renovation | £2,000 to £4,000+ |
Costs will vary depending on property condition, specification, location, and the extent of structural alterations.
For an average sized home, this often translates to:
- One-bedroom flat: £40,000 to £80,000
- Two-bedroom house: £60,000 to £120,000
- Three bedroom house: £90,000 to £250,000+
- Larger family homes: £150,000 to £500,000+
The full house renovation costs that London homeowners pay are usually higher than the national average due to increased labour costs, material prices, and local regulations.

Many contractors calculate renovation costs per square metre because it provides a useful benchmark when comparing projects.
Typical cost ranges include:

A light refurbishment generally includes:

- Minor electrical work
- Cosmetic improvements
Average cost: £750 to £1,250 per square metre

Average cost: £2,000 to £4,000+ per square metre
What Affects House Renovation Costs?
Every home renovation project is different. Several factors can influence the total project cost.
Property Type
The property type has a major impact on renovation costs.
Victorian and Edwardian homes often require additional structural surveys, electrical upgrades, and insulation improvements. Modern properties may be simpler to renovate but can still require substantial work depending on their condition.
Structural Alterations
Structural alterations are among the biggest drivers of cost.
Common examples include:
- Removing load bearing walls
- Creating an open plan space
- Adding extensions
- Loft conversion projects
- Basement conversions
Structural changes require calculations from a structural engineer and often involve structural engineer fees alongside construction costs.
Labour Costs
Labour costs account for a large proportion of the total construction cost.
London tradespeople typically charge more than those in other parts of the UK, particularly compared to the national average. If your property is in Central London or the South East, you can expect labour costs to increase significantly.
Project Complexity
Project complexity affects both timescales and budgets.
For example, replacing kitchen units is a relatively straightforward task. However, relocating bathrooms, installing a new heating system, or removing load bearing walls creates a much more complex building project.
Typical Cost Breakdown for a Full House Refurbishment
Understanding the cost breakdown can help homeowners create a more accurate renovation budget.
For a typical three bedroom house refurbishment in London:
| Item | Estimated Cost |
| Kitchen Renovation | £15,000 to £40,000 |
| Bathroom Renovation | £8,000 to £20,000 |
| Electrical Work | £6,000 to £15,000 |
| Central Heating | £5,000 to £15,000 |
| Decorating | £5,000 to £15,000 |
| Flooring | £4,000 to £12,000 |
| Structural Work | £10,000 to £100,000+ |
| Project Management | 5% to 15% of build cost |
This cost breakdown illustrates how quickly the total budget can increase when multiple areas of a property require refurbishment.
Professional Fees to Consider
Many homeowners focus solely on construction costs and overlook professional fees.
These may include:
- Architect fees
- Structural engineer fees
- Surveyor costs
- Building control fees
- Planning consultants
- Project management services
Professional fees typically account for 10% to 20% of the total project cost.
Planning Permission and Building Regulations
Depending on the renovation work you carry out, you may need planning permission from your local council.
Projects commonly requiring approval include:
- Large extensions
- Loft conversion projects
- Structural alterations
- Listed building works
Building Regulations approval is often required for:
- Electrical work
- Structural work
- Heating systems
- Insulation upgrades
- Drainage modifications
Before beginning any building process, homeowners should review the latest guidance available through GOV.UK and their local council.
Hidden Costs That Affect the Final Cost
Unexpected costs are one of the biggest challenges in renovation projects.
Common hidden costs include:
- Damp treatment
- Asbestos removal
- Roof repairs
- Drainage issues
- Structural defects
- Upgrading outdated wiring
- Temporary accommodation during works
These hidden costs can significantly increase the final cost of a renovation project.
For this reason, we always recommend including a contingency budget of at least 10% to 20%.
How to Reduce Renovation Costs
Many homeowners ask how they can reduce renovation costs while still achieving excellent results.
Create a Realistic Budget
A detailed renovation budget helps prevent overspending and ensures all aspects of the project are accounted for.
Retain Existing Layouts
Moving kitchens and bathrooms often requires extensive plumbing and electrical work. Keeping services in the same location can save money.
Prioritise Essential Work
Focus on structural renovation and essential upgrades before investing in cosmetic improvements.
Plan Everything Before Construction Starts
Changes during the building process are one of the most common causes of budget overruns.
Effective cost control begins with detailed planning.
Work with Experienced Professionals
Professional project management helps avoid delays, mistakes, and unexpected costs that can increase the total cost.
Is a Full House Renovation Worth It?
For many homeowners, a full house renovation offers a better return on investment than moving house.
Benefits include:
- Increased property value
- Improved energy efficiency
- Better use of space
- Modern heating systems
- Reduced maintenance costs
- Improved lifestyle and comfort
While the full renovation budget may appear significant initially, many homeowners find the long-term benefits outweigh the costs.
