WPC decking buying guide: base, area, claims
Updated: October 2026
You are about to pay for a patio, a low garden deck or a flat balcony slab, and the basket treats a tile pack, a board and a platform as one product. A WPC decking buying guide starts with the base, then the material line, then the area you count yourself. The [WPC decking comparison](/hub/fencing-and-wire/wpc-decking) ranks the six amazon.co.uk listings from 15 October 2026. This page is the checklist of trade-offs, not the laying steps and not the timber choice. Products Compared used those listings, not a lab. A qualifying purchase through our links can earn a commission at no extra cost to you.

Tiles, boards or a platform
Buy the object that matches the ground. Interlocking tiles sit on a flat base you already have. Extruded boards need a subframe and that board’s joist chart. A platform with feet is a third job.
On 15 October 2026 the tile packs were about £32.99 for eleven and about £42.99 for sixteen. The platforms were about £255.99 to £361.01. A £33 pack and a £361 module are not the same square metre. The best WPC decking page makes the pick. If the listing gives two sizes, stop.
What the material line has to say
You want the material line to say WPC or a composite panel. Plastic-only tiles, engineered wood, and a field that names a timber species are different products, even if a bullet says imitation wood. Here the line only has to be one material.
Hollow is often lighter and less strong than solid. A cap adds a wear layer. This set mostly does not say which. None of these listings states the core or a joist chart. BS EN 15534-4:2014 covers external WPC profiles and tiles, not kits. No report number is on these pages. The floating deck says Acacia and also an imitation-wood panel. That fails the material test before price matters.
Count the area yourself
A 30 cm square is 0.09 square metres. Eleven tiles are about 0.99 square metres. Sixteen are 1.44. Rounding eleven tiles to 1 square metre is close. It is not close for sixteen. The brown pack says sixteen tiles and also 1.0 square metre. Believing the area line means about a square metre at about £42.99. Counting tiles means about 1.44 square metres. The eleven-tile pages also say 1.0 square metre, only a small rounding of 0.99.
One eleven-tile pack is a small slab, not a terrace. The wood pack states 2.2 cm. The grey pack, at the same price, does not. Board prices are context only: add joists and clips before you call a board cheaper than a tile pack.
Height, consent and a fall
A correct pack can still need permission. In England, a garden deck over 30 cm is outside the usual householder limits, which also include half the garden and the principal elevation. An upper-floor balcony is outside those rights. Flats, listed buildings and Article 4 directions change the answer. Wales uses 30 cm and adds a side-to-highway limit, for houses, not flats. Scotland allows a floor of 0.5 m and 2.5 m overall with a rail. Northern Ireland is separate. Do not copy the English 30 cm figure north or across the Irish Sea. Approved Document K, for dwellings in England, says you guard a fall of more than 600 mm, with 1100 mm at an external balcony. Tiles do not add that rail. One site, a balcony slab, is on the balcony page.
Claims that are not a test
Stars and prices here are from the amazon.co.uk listings of 15 October 2026, not a slip test. The three VOUNOT colours show 3.9 from 17 and the same review text, one parent rating. Anti-slip and waterproof are seller sentences. The TDCA cites a wet pendulum value of 36 or more as the HSE low-slip threshold. None of these listings publishes one. Do not claim a fire class.
Refuse a listing that contradicts itself. The spa deck gives two sizes. The campsite deck hides its size in the model string. The floating deck names Acacia and a composite panel.
Match the base, then count the tiles
If the ground is a flat slab you can cover and lift, buy click tiles and count the pieces. If you need boards, price the frame as well. If the material line names a timber species, or the page gives two sizes, stop.
Common questions
Are click tiles and composite boards the same buy?
No. Click tiles go on a firm, flat base, and the VOUNOT pages say they join without glue or screws. Composite boards need a subframe, clips and that board’s joist chart, which these six listings do not include. A platform with feet is a third object. Match the buy to the base before you compare a pack of about £33 with a module near £300.
How much does a 30 cm tile cover, and why does a pack say both 11 tiles and 1.0 square metre?
One 30 cm square is 0.09 square metres, so eleven tiles are about 0.99 square metres. Sixteen tiles are 1.44 square metres, and the brown pack still says 1.0 square metre. Count the tiles. Do not take the area line as the cover you will walk on.
Does anti-slip, waterproof or 300 kg per square metre mean it was tested?
No. Those lines are seller wording. A wet pendulum value of 36 or more is the HSE low-slip threshold the TDCA cites, and none of these listings publishes one. BS EN 15534-4:2014 covers external WPC profiles and tiles, not kits, and no report number is on these pages. The 300 kg figure on the spa deck has no certificate in the file.
When does a garden deck need planning permission in England, Wales or Scotland?
In England and Wales, a garden deck over 30 cm is outside the usual householder limits, which also cover half the garden and the principal elevation. Wales adds a side-to-highway limit, and those rights are for houses, not flats. Scotland allows a floor of 0.5 m and 2.5 m overall with a rail. Northern Ireland is separate. An upper-floor balcony sits outside those householder deck rights.
Which of these six listings should you refuse to design from?
Stop on the spa deck, because the highlight and the specification table give two sizes. Stop on the campsite deck, because the size is only in the model string. Stop on the floating deck, because the material line says Acacia and the bullets say a composite panel. The three VOUNOT packs can be counted as tiles.
