How Much Does House Cladding Cost Per Square Metre in 2026? Timber Composite and Render Board Prices Compared
A typical three bedroom semi detached house in the UK with around 90 m² of external wall area might cost anywhere from £7,000 for basic uPVC cladding to £18,000 or more for a high end composite or rendered insulation system in 2026. That is a wide spread, and it shows why understanding house cladding cost per square metre is only the starting point. Homeowners who plan properly can avoid overspending, improve energy efficiency, and add real value to their property.
House cladding cost per square metre in the UK varies widely in 2026, driven by material choice, insulation requirements, scaffold access and labour rates. As a working benchmark, most homeowners are paying anywhere from £60 per m² for basic uPVC cladding through to £180 per m² or more for premium composite or fully rendered insulation systems.
Those broad figures only tell part of the story. Cladding is rarely just a decorative upgrade. It is often tied into weatherproofing, insulation and compliance with Building Regulations. Poor decisions at specification stage can lead to damp issues, movement cracking or even expensive remedial work within a few years.
This guide breaks down current UK costs per square metre, explains how timber, composite and render board systems compare, and outlines what actually affects the final price you will be quoted by a competent tradesperson.
What Is Included in House Cladding Costs Per Square Metre
Quoted prices can vary dramatically depending on what is included. Some installers price materials only, others bundle everything into a supply and fit rate. Before comparing quotes, you need to understand what should be covered.
- Removal of existing finishes such as render or old cladding
- Preparation of substrate walls including repairs
- Breather membranes and battens or rail systems
- Insulation layers if part of the build up
- Cladding panels or boards
- Corner trims, window reveals and ventilation gaps
- Scaffolding and access equipment
- Labour and waste disposal
If insulation is involved, the project moves into the territory covered in External Wall Insulation for UK Homes Explained Systems, U Values, Render Finishes and Common Pitfalls to Avoid, and costs increase significantly.
Average House Cladding Cost Per m² in the UK 2026
The table below reflects realistic installed costs based on current contractor pricing across England and Wales. London and the South East typically sit 10 to 20 percent higher.
| Cladding Type | Materials Cost per m² | Labour Cost per m² | Total Installed Cost per m² | Expected Lifespan |
|---|---|---|---|---|
| uPVC Cladding | £20 to £35 | £25 to £45 | £60 to £80 | 20 to 30 years |
| Timber Softwood | £25 to £50 | £40 to £70 | £70 to £120 | 15 to 25 years |
| Timber Hardwood | £60 to £110 | £50 to £80 | £110 to £180 | 25 to 50 years |
| Composite Cladding | £50 to £90 | £40 to £70 | £100 to £160 | 25 to 40 years |
| Fibre Cement Boards | £40 to £70 | £45 to £75 | £90 to £140 | 30 to 50 years |
| Render Board Systems | £60 to £110 | £70 to £120 | £130 to £200 | 25 to 40 years |
These figures assume straightforward access and a typical two storey property. Complex detailing around dormers or bay windows can push labour costs up sharply.
House Cladding Cost Per Square Metre Breakdown by System
Understanding house cladding cost per square metre in detail means looking at how each system is built and where the money goes. Labour often accounts for 40 to 60 percent of the total cost, especially on more technical systems like render boards or fibre cement.
Premium branded systems such as Cedral fibre cement boards or Marley Eternit panels cost more upfront but tend to offer better durability, colour stability and fire performance. That reduces long term maintenance costs and risk.
Timber Cladding Costs and Considerations
Timber remains one of the most popular cladding choices for UK homeowners. It offers a natural finish and suits both traditional and contemporary builds.
Softwood Cladding
Softwood species such as pine or spruce are at the lower end of the cost scale. Expect installed prices between £70 and £120 per m².
However, softwood demands regular maintenance. Staining or painting is usually required every three to five years. A typical repaint on a semi detached house can cost £1,000 to £2,000 depending on access.
If maintenance is ignored, boards begin to cup and split. Water ingress follows, often leading to hidden rot within battens and structural timbers. Repairing this can easily run into several thousand pounds.
Hardwood Cladding
Hardwoods such as cedar, larch or oak cost more upfront but last longer. Installed costs often fall between £110 and £180 per m².
Western red cedar and Siberian larch are widely used in the UK. Cedar, in particular, is naturally resistant to decay. It can be left untreated to weather to a silver grey, reducing maintenance costs.
Some homeowners choose factory finished timber systems with UV protective coatings. These add cost but extend maintenance intervals to 7 to 10 years.
Installation Factors
Timber cladding must be installed over a ventilated cavity. This is not optional. It is required to comply with moisture control standards set out in Approved Document C.
Breather membranes, correct batten spacing and insect mesh are all part of a proper installation. Stainless steel fixings are also recommended to avoid staining and corrosion.
Composite Cladding Cost Per m²
Composite cladding has gained traction due to its low maintenance and consistent finish. Made from recycled wood fibres and plastics, it mimics timber without the same upkeep.
Installed costs typically range from £100 to £160 per m².
Popular UK products include brands like Millboard and Trex adapted for cladding applications. These systems offer improved slip resistance, UV stability and longer warranties.
Advantages include:
- No painting or staining required
- Good resistance to rot and insects
- Uniform colour and finish
There are trade offs. Composite boards expand and contract more than natural timber. Installers must follow manufacturer guidance around expansion gaps and fixing systems.
Lower cost composite products often suffer from fading or surface chalking after prolonged UV exposure. Mid range and premium boards include capped surfaces to prevent this.
Most composite systems come with warranties between 20 and 30 years, but these usually cover structural integrity rather than appearance.
Render Board Cladding Systems Explained
Render board systems offer a clean, modern finish and are often used to transform older properties. These systems involve fixing cement or insulation boards to the wall, then applying a render finish.
If you want detail on render types, see Render Systems Explained Silicone Acrylic Monocouche and Mineral Finishes Compared.
Costs and Build Up
Installed costs range from £130 to £200 per m² depending on specification.
A typical build up includes:
- Carrier board or insulation board
- Base coat render with mesh reinforcement
- Primer
- Finish coat such as silicone render
High quality systems from manufacturers such as Weber, K Rend, or Parex are widely used across the UK. These systems are designed to work as a complete package, which reduces the risk of cracking or failure.
Systems that include insulation overlap with the pricing explained in How Much Does Exterior Wall Insulation Cost in 2026? Materials, Labour and Render Finish Prices Explained.
Silicone renders are now the preferred finish due to flexibility and water resistance. They cost more than monocouche or sand and cement but last longer with fewer cracks.
Incorrect installation is a major cause of failure. Missing mesh reinforcement or poor curing conditions can lead to cracks within months.
Comparing Cladding Types for UK Homes
Choosing between timber, composite and render board is not just about cost. Performance, maintenance and appearance all play a role.
| System | Pros | Cons |
|---|---|---|
| Timber | Natural look, widely available, flexible design | Regular maintenance, risk of rot, shorter lifespan if untreated |
| Composite | Low maintenance, consistent finish, long lifespan | Higher upfront cost, expansion movement, can look artificial |
| Render Board | Modern finish, improves insulation, durable | Higher cost, requires skilled installation, risk of cracking if poorly applied |
Properties in exposed coastal areas benefit from composite or rendered systems due to resistance to moisture and salt air.
Lifecycle Costs Over 20 to 30 Years
Initial installation cost is only part of the picture. Over 20 to 30 years, maintenance and repair costs can significantly change the overall value of each system.
| System | Initial Cost | Maintenance Costs | Typical 25 Year Total |
|---|---|---|---|
| Timber | Medium | High, repainting every 3 to 5 years | High overall |
| Composite | High | Low, occasional cleaning | Medium |
| Render Board | High | Low to medium, minor repairs and cleaning | Medium |
A timber clad house may need repainting five or six times over 25 years, costing £5,000 to £10,000 in total. Composite may only need cleaning, while render systems may require occasional crack repairs costing a few hundred pounds.
Real Project Cost Examples
| Property Type | Wall Area | Material | Total Cost Range |
|---|---|---|---|
| Terraced House | 50 to 70 m² | uPVC | £3,500 to £5,500 |
| Semi Detached | 80 to 100 m² | Composite | £10,000 to £15,000 |
| Detached House | 120 to 180 m² | Render Board System | £18,000 to £30,000 |
Additional Costs That Affect Cladding Jobs
The per square metre figure rarely tells the full story. Several factors influence the final quote.
Labour Rates
Typical UK labour rates range from £150 to £300 per day per tradesperson. Specialist cladding installers or render teams usually sit at the higher end due to experience and certification requirements.
Regional Differences
Costs in London and the South East are typically 10 to 20 percent higher than the national average. Northern regions and Wales may offer slightly lower labour rates, but material costs remain similar nationwide.
Access and Site Constraints
Narrow streets, limited parking or restricted access can increase labour time and scaffold costs. Properties with height restrictions or difficult access may require specialist scaffolding, adding £1,000 or more to the project.
Scaffolding
Most two storey homes require scaffolding. Expect £800 to £2,500 depending on complexity and duration.
Waste Removal
Removing old render or cladding can add £300 to £1,000. Hazardous materials such as asbestos increase costs significantly and require licensed contractors under Health and Safety Executive guidance.
Insulation Upgrades
Adding external insulation can add £80 to £140 per m² but significantly improves energy performance. For example, a solid wall with a U value of 2.1 W per m²K can be reduced to around 0.3 W per m²K after insulation, which meets Approved Document L targets.
Detailing
Window reveals, soffits and edges often require extra materials and labour. These details are where poor workmanship usually shows.
Planning Permission and Building Regulations
Many cladding projects fall under permitted development, but there are exceptions.
- Listed buildings require consent
- Properties in conservation areas may have restrictions
- Front elevations facing a highway are more likely to require permission
For example, replacing rear timber cladding may be allowed under permitted development, but adding modern composite cladding to a front elevation in a conservation area is often refused due to visual impact.
Check guidance from Planning Portal before starting.
Building Regulations may apply where insulation is added or structural elements are altered.
Approved Document B covers fire safety. Many modern cladding systems must meet Euroclass ratings such as A2 s1 d0, particularly on taller buildings. Fibre cement boards like Cedral often meet these higher fire performance standards.
Approved Document L sets thermal performance targets. If adding insulation, upgraded walls typically need to achieve U values around 0.3 W per m²K or better.
How Long Does House Cladding Take
Typical timelines vary depending on size and complexity.
- Small frontage, 3 to 5 days
- Semi detached house, 1 to 2 weeks
- Detached property, 2 to 4 weeks
Timeline by Cladding Type
uPVC cladding is the quickest to install and can often be completed within a few days on smaller areas.
Timber cladding takes longer due to cutting, sealing and detailing, usually around 1 to 2 weeks for a semi detached property.
Render systems are the slowest. Base coats, mesh and finish layers require curing time. Full systems can take 2 to 3 weeks, especially in cooler or damp conditions.
Weather delays are common, particularly for render which needs dry conditions to cure properly.
Common Mistakes to Avoid
Cladding failures are often down to shortcuts or poor planning rather than materials themselves.
- Skipping ventilation gaps behind timber or composite boards
- Using untreated battens that rot within a few years
- Incorrect fixings leading to movement or warping
- Poor detailing around windows allowing water ingress
- Choosing the cheapest render system without considering flexibility
- Ignoring insulation and moisture control requirements
Real world consequences can be severe. Trapped moisture behind cladding can lead to internal damp and mould, often costing £2,000 to £5,000 to remediate. Failed render systems may require full removal and replacement, sometimes costing more than the original install.

Warranties and Guarantees
Most cladding materials come with manufacturer warranties ranging from 10 to 30 years. These typically cover product defects but not installation errors.
Installers should provide workmanship guarantees, usually between 2 and 10 years. Always get this in writing and ensure the contractor has relevant insurance.
Maintenance Cost Breakdown
Maintenance varies significantly by material.
- Timber repainting every 3 to 5 years, £1,000 to £2,000
- Composite cleaning every 1 to 2 years, minimal cost
- Render cleaning or minor repairs every 5 to 10 years, £300 to £1,000
Factoring in these costs helps avoid underestimating long term spend.
Practical Checklist Before Starting a Cladding Project
- Confirm whether planning permission is required
- Decide if insulation will be included
- Get at least three detailed quotes with full breakdowns
- Check installer experience with your chosen material
- Ask about warranties for both materials and workmanship
- Ensure compliance with Building Regulations
- Plan scaffold access and site logistics
Spending time at this stage usually prevents overspending later.
FAQ
How much does it cost to clad a typical semi detached house in the UK?
For a standard semi detached property with around 80 to 100 m² of external wall area, total costs in 2026 typically range from £6,000 for basic uPVC to £16,000 or more for composite or render board systems. Adding insulation can push this beyond £20,000.
Is cladding cheaper than rendering?
Basic cladding such as uPVC is cheaper than most render systems. However, render board systems with insulation often provide better long term value due to improved energy efficiency and durability. Costs vary depending on specification, as outlined in the linked rendering guides above.
Does cladding add value to a property?
Well installed cladding can improve kerb appeal and energy efficiency, both of which influence value. Poorly executed work can have the opposite effect. Buyers and surveyors often look closely at finish quality and compliance with regulations.
What is the most low maintenance cladding option?
Composite and fibre cement boards require the least maintenance. They do not need painting and are resistant to rot. Timber requires ongoing treatment to maintain its condition.
Can cladding improve insulation?
Cladding alone does very little for insulation. When combined with external wall insulation systems, it can significantly improve thermal performance and reduce heating bills. This must meet Building Regulations for U values.
What is the cheapest way to clad a house in the UK?
uPVC cladding is generally the cheapest option, with installed costs starting around £60 per m². It offers a quick cosmetic upgrade but does not provide the same long term durability or insulation benefits as higher end systems.
How do I calculate how many square metres of cladding I need?
Measure the height and width of each external wall and multiply them to get the area in square metres. Subtract windows and doors for a more accurate figure. Most contractors will add 5 to 10 percent for waste and cuts.
Final Thoughts
Cladding is one of the most effective ways to update the look and performance of a UK home, but costs vary significantly depending on materials and specification. Timber offers character but requires upkeep. Composite provides durability with less maintenance. Render board systems deliver a clean finish and can transform older properties, particularly when paired with insulation.
The biggest cost driver is not always the material, but the quality of installation. Cutting corners on preparation or detailing leads to expensive problems later. Getting the specification right from the outset pays off over time.
If you are planning a cladding project, the easiest way to get accurate pricing is to post a job and receive quotes from vetted local tradespeople who understand your area and property type.
