How much does trex decking cost?

Question

We're done with sanding and staining the wooden deck every single year so composite is tempting. What does trex cost supplied and fitted compared to the cheaper composite brands?

James · Answer

Hi Minesh. Trex is definitely a great choice if you want to skip the annual sanding and staining. On average, you're looking at around £110 to £160 per square metre supplied and fitted for Trex, depending on whether you choose their entry-level or premium ranges.
Cheaper composite brands usually run closer to £80 to £120 per square metre. However, the budget stuff is often uncapped or hollow, which can warp, stain, or fade over time. Trex has a solid, wrapped protective shell and a 25-year warranty, so it generally works out cheaper in the long run if you plan on staying in the house.

Trex composite decking generally costs between £70 and £140 per square metre for the boards alone. If you account for a full professional installation—including the subframe, fixings, and labor—the comprehensive price ranges from roughly £100 to £250+ per square metre

Trex is one of the more expensive composite decking brands. The boards alone cost roughly £100–£135 per square metre, and once you add labour and the frame underneath, most people pay £250–£400 per square metre all-in. So a typical 15m² deck would land somewhere around £4,000–£6,000 fitted.

Cheaper composite brands usually cost about half as much for the materials. The difference is that Trex lasts longer, doesn't fade as quickly, and comes with a 25–50 year guarantee. If you plan to stay in the house a long time, it's worth paying extra. If you're on a tight budget, a mid-range composite from another decent brand is a sensible compromise — just avoid the very cheapest uncapped stuff, which can stain and fade within a few years.

If you're thinking about fitting composite decking instead of timber, the main benefit of Trex is that you can forget the yearly sanding, staining and painting. It costs more initially, but it can save a lot of maintenance over time.
Small deck 10m2. £800-1800 depending on brand

Greg · Answer

Trex is approx. £130 per square metre, but not really better than other products

Conor · Answer

In the UK, Trex decking generally costs £70 to £140 per m² for the boards alone, or £150 to £300+ per m² fully installed including the subframe, fixings, and labor.

Trex is definitely at the premium end of composite decking. As a rough guide, you could be looking at around £150–£250+ per m² supplied and fitted, depending on the Trex range, the size of the deck, ground preparation and whether it’s raised.

For example, a straightforward 15m² deck could roughly be £2,500–£4,000+. Trex itself can vary quite a bit by range, with the higher-end options costing considerably more.

The upside is that composite doesn't need the yearly sanding, staining and treating that timber does, so it's worth comparing the long-term cost, not just the initial price.

It completely makes sense why you're looking to switch ditching the annual sanding and staining cycle is the main reason most people move over to composite!

To give you an idea of the numbers for supplied and fitted (including materials, subframe, and labor):

 * Cheaper/Mid-Range Composite Brands: Usually run around £120 to £180 per m^2. They are easier on the wallet upfront, but many use hollow-core boards and have shorter lifespans or more basic fade warranties.

 * Trex Decking: Generally ranges from £220 to £350+ per m^2. Trex is essentially the premium gold standard—it's a heavy-duty, solid-core capped board that won't fade, stain, or splinter, and it comes with a solid 25-year manufacturer warranty.

While Trex has a higher upfront cost, you truly get what you pay for in terms of durability and how it holds its look over the decades.

If you'd like, I can pop over sometime to measure up the area and give you an exact, itemised quote for both a budget-friendly composite option and a Trex option so you can weigh them side-by-side.

Hi there 

So composite is a mix of wood and plastic fibres that gives you a twenty five year guarantee which is only a small difference to the price of timber and then depending on wether the whole deck is compostie or just the boards its something to consider but depending on the size of your deck your looking at twice the price as standard timber decking unless you go with a hardwood deck, which is what I would recommend and a deck built by us is guaranteed for ten years.

Not a massive difference apart from designs and look between the enhance and transcend editions. Also the fact that the transcend is more durable and longer lasting than the other. Same with millboards, just classed a as “premium”

Cladco is a eco friendly/ budget composite

Few quid difference in materials but that’ll depend on supplier. Labour shouldn’t play apart of what composite is being installed and price as a labour price
