Composite decking prices vary enormously depending on board quality, subframe material, ground conditions and regional labour rates. This guide gives you accurate 2026 price ranges across every variable so you can budget realistically before requesting quotes.
NeverMowUK installs composite decking across the North West, Midlands and Yorkshire. The prices in this guide reflect what homeowners in these regions actually pay in 2026.
Average Composite Decking Cost in the UK in 2026
For a standard residential composite decking project, expect to pay between £100 and £200 per square metre for supply and installation combined. This range covers the full variation from entry level products with a timber subframe through to premium capped composite boards on an aluminium frame.
| Project Size | Budget per m2 | Mid Range per m2 | Premium per m2 | Approx Total |
| Small, up to 15m2 | £110 to £130 | £140 to £165 | £170 to £200 | £1,650 to £3,000 |
| Medium, 15 to 30m2 | £100 to £120 | £130 to £155 | £160 to £190 | £3,000 to £5,700 |
| Large, 30 to 50m2 | £90 to £110 | £120 to £145 | £150 to £180 | £4,500 to £9,000 |
| Extra large, over 50m2 | £80 to £100 | £110 to £135 | £140 to £170 | £7,000 plus |
These ranges include all groundwork, subframe, boards, fixings, edge trim and labour. They do not include steps, handrail systems or integrated lighting, which are quoted separately.
What Is Included in a Full Composite Decking Installation
| Installation Component | Description | Typically Included |
| Ground preparation | Clearing, levelling, removing existing surface | Yes |
| Subframe installation | Timber, composite or aluminium joists | Yes |
| Board supply and fitting | Main visible surface | Yes |
| Edge finishing | Fascia boards or trim around perimeter | Yes |
| Skip hire for waste | Removal of excavated material | Confirm with installer |
| Steps or staircases | Access modifications | Usually quoted separately |
Always confirm whether skip hire is included. On larger projects, skip costs can add £300 to £800 to the total.
Composite Board Types and Their Impact on Cost
Capped vs Uncapped Composite
| Board Type | Stain Resistance | UV Resistance | Scratch Resistance | Price Premium |
| Fully capped composite | Excellent | Excellent | Good | 20 to 35 percent over uncapped |
| Uncapped composite | Moderate | Moderate | Moderate | Base price |
Capped composite boards have a protective polymer sleeve surrounding the composite core on all four sides. Uncapped boards absorb moisture and staining through cut ends and worn surfaces over time, leading to fading, mould growth and surface deterioration within five to ten years. Capped boards maintain their appearance significantly longer. NeverMowUK specifies capped composite boards on all projects as a minimum standard.
Solid Core vs Hollow Core
Solid core boards are denser, feel more like natural timber underfoot and provide better impact resistance. They cost 15 to 25 percent more per square metre than equivalent hollow core products. Hollow core boards are lighter, easier to handle and less expensive. Both offer equivalent weather resistance for most domestic applications.
Subframe Options and Their Effect on Cost and Longevity
| Subframe Material | Cost vs Timber | Expected Lifespan | Maintenance |
| Pressure treated timber joists | Base cost | 15 to 20 years | Annual inspection |
| Composite joists | 20 to 30 percent more | 25 years plus | Near zero |
| Aluminium frame system | 40 to 60 percent more | 30 to 40 years | Zero |
The subframe is never seen once the deck is complete, which is why budget installers most commonly reduce costs here. A composite deck with premium boards on a poor quality timber subframe will develop problems as the subframe rots or shifts. NeverMowUK uses treated timber as a minimum and recommends aluminium frame systems for elevated decks and any project where the subframe will be exposed to standing water.
Additional Costs That Affect the Total Price
| Additional Feature | Approximate Cost |
| Single step flight, 1.2m wide | £300 to £600 |
| Handrail system per linear metre | £80 to £150 |
| Integrated post lighting per post | £100 to £200 |
| Aluminium frame upgrade per m2 over timber | £15 to £30 |
| Skip for waste disposal | £200 to £400 |
Elevated Decking and Planning Permission
Composite decking installed above 600mm from ground level in England and Wales may require planning permission. Properties in conservation areas should check with their local planning authority before proceeding.
Regional Pricing: North West, Midlands and Yorkshire
Labour rates vary across the UK. The North West, Midlands and Yorkshire generally have lower labour costs than London and the South East.
In the North West, covering Manchester, Bury, Bolton, Stockport, Wigan, Salford and Warrington, composite decking at mid range specification typically costs £125 to £155 per square metre all inclusive.
In the Midlands, covering Birmingham, Wolverhampton, Stoke on Trent, Coventry, Derby and Nottingham, comparable specification typically costs £120 to £150 per square metre.
Across Yorkshire, including Leeds, Sheffield, Bradford, Huddersfield and Wakefield, mid range composite decking installation typically costs £115 to £145 per square metre.
Composite Decking vs Hardwood Timber: 20 Year Cost Comparison
| Factor | Composite Decking Capped | Hardwood Timber |
| Supply and install cost per m2 | £100 to £200 | £80 to £160 |
| Annual maintenance cost | Near zero | £150 to £300 (oiling, sanding) |
| Lifespan with correct maintenance | 25 years plus | 15 to 25 years |
| 20 year total cost on 50m2 deck | £7,500 to £10,000 | £12,500 to £18,000 |
| Splinter risk | None | Yes, particularly as it ages |
| Colour without oiling | Holds colour with capped boards | Fades to silver grey |
Over a 15 to 20 year period, composite decking is consistently more cost effective than hardwood timber when maintenance is factored in.
Frequently Asked Questions
Does composite decking add value to a property? Yes in most cases. An attractive, well installed composite deck is viewed positively by buyers looking for low maintenance outdoor space. Value added depends on size, quality and property type.
How long does composite decking installation take? A standard deck of 20 to 30 square metres typically takes two to three days. Larger projects and elevated decks take proportionally longer.
Is composite decking slippery when wet? Quality capped composite boards have a textured surface that provides grip in wet conditions. Budget uncapped composite can become slippery when wet and covered in algae. Choosing a quality product and keeping it clean prevents this.
Can I install composite decking myself? DIY installation is possible for flat, ground level decks. However, professional installation ensures the subframe is correctly specified, hidden fixings are installed correctly and edge finishing is clean.
What questions should I ask a composite decking installer? Ask for the product specification sheet, confirm whether the board is fully capped, ask for the UV resistance specification, confirm the subframe material and ask for the written guarantee period covering both product and workmanship.
