What Is the Average Cost of a House Renovation in the UK (2025)?
The typical cost of renovating a house in the UK in 2025 ranges from £1,200 to £2,800 per square metre, depending on how high-spec your project is and where you live.

Understanding the Cost per Square Metre
Renovation cost doesn’t come at a flat rate. It changes depending on what interior style you are after, quality of finish, and how complex the job is. Here’s a simplified guide based on current 2025 figures:
Specification | Average Cost per m² | Example Total (100 m²) |
|---|---|---|
Basic | £1,200 | £120,000 |
Mid-range | £1,800 | £180,000 |
High-end | £2,400–£2,800 | £240,000–£280,000 |

Factors That Affect Renovation Cost
A few key things will shift you up or down the price scale:
- Property type – Flats and terraces can be more expensive per square metre due to space and layout constraints.
- Project scope – Simple redecoration is cheaper than structural work like taking down walls or installing underfloor heating.
- Location – Expect higher costs in London and the South East - often by 30% or more.
- Materials and labour – costs can vary significantly depending on the quality of labour and materials used.
How Renovation Specification Affects Cost
The quality of materials and finishes you choose has a huge impact on your overall renovation budget. Understanding the different specification levels helps you plan your project more effectively.
Level 1: Basic
Basic specification materials are budget-friendly and reasonably reliable. Brands like Leyland, Everest, and Wickes fall into this category. These are cost-effective options, but keep in mind that you may need a refresh sooner than if you used materials that are a bit more expensive. This specification level is suitable for rental properties, first-time renovations, or projects with strict budget limitations.
Level 2: Standard
Standard specification materials offer a good balance between quality and cost. These mid-range products offer both durability and aesthetic appeal. Brands such as Dulux, Hamilton, and Slim Line fall into this category. This specification level suits most homes and is the most common choice for UK renovations. Solid quality - no excessive costs.
Level 3: Premium
Premium specification materials are the most expensive, high-quality, and visually appealing. Luxury brands like Farrow & Ball, Fine Line, and Siemens fall into this category and are ideal for premium projects where you need the highest quality. Premium materials do need a large investment, but they tend to deliver better results and add value to your property.
What Each Room Typically Costs to Renovate
Some rooms cost more than others and the cost can vary significantly. On average, you can expect to pay between £4,000 and £30,000 per room, depending on its size, purpose, and level of finish.

Things That Affect Room-Specific Costs
Kitchens and bathrooms tend to cost more to renovate, because they require more specialist labour and material. This includes things like:
- Multiple trades (plumbing, electrics, tiling, carpentry)
- High-value materials (appliances, fixtures, fittings)
- Regulations (building control, ventilation, gas safety)
Bedrooms tend to be cheaper unless you're moving walls, creating en‑suites, or adding storage. Living rooms sit somewhere in the middle — straightforward to renovate. They tend to get more expensive if you want built-in cabinetry, fireplace or smart home technology installation.
How Location Affects Renovation Costs Across the UK
Renovation costs in the UK can vary by as much as 30 to 40 percent depending on where you live, with London and the South East sitting at the top end of the price spectrum, and regions like the North East and Wales often offering more affordable rates.

How First-Time Renovators Can Save Money
First-time renovators can reduce costs by making clever design choices, phasing their project, and avoiding common planning pitfalls.
Renovation isn’t cheap - but there are smart ways to stay on budget.
Practical Ways to Keep Renovation Costs Under Control
Lack of experience, rushed decisions, or simply trying to do too much at once are the most common reasons why renovation costs get out of hand. Here are a few strategies to help you save money without compromising the quality of your renovation project.
1. Watch Out for “Specification Creep"
It’s easy to get drawn into high-spec Pinterest ideas. But every extra feature — from custom handles to underfloor heating — adds both cost and complexity. That doesn’t mean you should compromise on your dream outcome, just keep in mind that every little detail matters.
As a first-time renovator, remember: clean, well-finished, and functional spaces tend to work the best.
2. Start with a clear plan
Changing your mind mid-build is expensive. Lock in layouts, finishes and any key decisions before a single wall comes down. For example, a delay in choosing bathroom tiles can hold up trades and push costs up across the board.
3. Use standard sizes and materials
Custom features drive up both labour and materials. Opting for standard door heights, tile dimensions, and off-the-shelf cabinetry will save you a lot of money.
4. Use one contractor for multiple tasks
Hiring a general contractor or design-and-build team often brings down the cost of renovation. Having multiple trades might seem cheaper, but mistakes and miscommunication between contractors can cost more in the long run.
5. Set aside a contingency budget
Budgeting for a full-house renovation means breaking down costs into clear categories, setting realistic allowances, and building in a contingency of at least 10 to 15 percent.
A detailed budget gives you control over your spending and helps prevent last-minute financial surprises. Going without contingency is one of the biggest renovation risks.
Costs That Are Easy To Miss
Too many first-time renovators focus only on building costs. But there are other essentials to include. Make sure you account for these categories in your budget:
- Planning and building control fees
- Fees and VAT
- Skip hire and site clearance
- Insurance for renovation works
- Temporary accommodation if the home becomes unliveable
- Snagging and remedial works after completion
Frequently Asked Questions
1. Do you need planning permission for a renovation in the UK?
Not always. Internal renovations typically don’t need planning permission, but structural changes, extensions, or altering the building’s appearance often do. You will need planning permission if:
- Your property is listed
- You live in a conservation area and the work affects the building's character
- You're making significant structural changes that alter the external appearance
- You're adding an extension that exceeds permitted development rights
Building regulations approval is always required for structural changes, regardless of planning requirements.
2. Do you need a project manager for a house renovation?
Not necessarily. A project manager is useful for coordinating trades and timelines, especially on large or complex renovations. If you're confident and well-organised, you may manage it yourself — but it comes with risks.
3. Should I move out during a renovation?
This depends on the extent of the work and your personal circumstances. Factors like dust, noise, lack of essential facilities, safety, and the overall disruption to daily life can be overwhelming. So, if you are renovating a whole house, getting temporary accommodation is a wise idea.
3. Do home renovations add value in 2025?
Yes. Kitchens, bathrooms, and loft conversions can significantly increase property value. However, keep in mind that poorly executed or over-personalised renovations may not deliver a return. If you're renovating with a view to sell - make sure to appeal to a variety of tastes.
4. Why do renovation costs vary so much across the UK?
Costs reflect local labour rates, supply chain logistics, property types, and regional demand. London and the South East are most expensive, while the North East and Wales tend to be more affordable.
5. Why should first-timers consider renovating room by room?
It tends to be cheaper in the short term, comes with less disruption, and gives you time to make informed decisions at your own pace., and gives you time to make informed decision at your own pace. While it can cost slightly more in the long-run, it’s often more manageable and less stressful for first-time renovators.
6. Do you have to pay VAT on renovation work?
In most cases, yes — 20% VAT applies. Some exemptions exist for listed buildings, energy-efficiency upgrades, or converting non-residential spaces. Always check with a qualified accountant or VAT specialist.
