Decking buying guide

Updated: 21 October 2026

A search for decking can land on a rubber mat, one raised platform, or a timber frame. This decking buying guide puts the choice in order: the system, the square metres a pack really covers, the load the listing will stand behind, and the planning line for the height you will build. The [decking comparison](/hub/flooring/decking) sorts the five amazon.co.uk listings we kept. The Products Compared editorial team used those listings from 19 October 2026, plus Planning Portal, GOV.UK, and Timber Decking and Cladding Association pages. We did not run a laboratory test. A qualifying purchase through our links can earn a commission at no extra cost to you.

Tiles, a kit, or boards

Start with the ground, not the colour. Interlocking tiles in this set cover a firm surface you already have. The Nicoman packs are rubber, made in Poland, and sold as residential click tiles. The Airsell nine-pack is plastic. None includes joists, posts, or a frame. A solid patio, old boards, or a balcony floor can take a tile pack if you only want to hide a tired surface. The GY8PKVWKWQ listing is one modular platform, with adjustable metal feet claimed. The material field says Acacia. The bullets describe an imitation-wood panel and a metal frame, and there is one amazon.co.uk review. A unit count of one is one square, not a run of deck. Boards are not in this set. A joisted deck carries people over open ground or a drop, with Use Class 4 on the frame. If the garden is soil, or the deck must rise, read decking tiles vs boards before you order.

What a pack really covers

A 300 mm square is 0.09 m² if the title is exact, so measure a tile before you commit the patio. The Airsell colour name states 0.81 m² for nine tiles. The light-grey 40-pack is about £33 a square metre as a rule of thumb. The platform is one 80 cm module, not a tile price. Order extra for a drain cover and a cut around a downpipe. Those offcuts will not click back into a full square. The light-grey 10-pack and 40-pack share one parent rating of 4.3 from 156. Adding the two lines would invent a second test. Who each pack is for is on best decking tiles.

Load, slip, and colour

Nicoman’s bullets say the tiles are not suitable for heavy loads, even where a hot tub is in the title. No filled-tub weight is printed. The Airsell listing and the platform state no load. A spa, a large planter, or a stored motorbike needs a different product. No listing here publishes a wet pendulum value. The TDCA treats a wet PTV of 36 or above as low slip potential on timber decks. That band is for boards. Anti-slip bullets and barefoot reviews are not a laboratory score, and they do not cover algae. Buy a sample for colour. Light-grey reviews include a box that missed an older grey, a patch that paled after rain and sun, and a later box that missed tiles laid a month earlier. One review called the tiles almost black.

Planning and falls

The 30 cm householder line and the 600 mm guarding line are different tests, and the questions below set them out. A low deck can still need a barrier if the ground beyond it drops. A deck that meets the house or rises above 300 mm is a building-control conversation, not a click-tile afternoon. Click gaps do not drain a bowl-shaped patio. The listings do not say whether the tiles can go on grass. If the home is a flat, the householder chapter is the wrong one: balcony decking tiles. If the job is joists over soil, the tile price is the wrong comparison.

Common questions

Do I need planning permission for garden decking?
For a house, the Planning Portal describes permitted development at no more than 30 cm, within 50 per cent of the garden, and not forward of the principal elevation. GOV.UK treats a platform over 0.3 m as raised, outside that class. Designated land, a listed building, and anything in front of the house can still need an application. It does not apply to flats.
Is 30 cm the same rule as 600 mm?
No. Thirty centimetres is the planning height in the householder class the Planning Portal describes. Six hundred millimetres is the fall at which Approved Document K, for England, expects guarding. A low deck can fail planning for other reasons, and a taller drop can need a barrier even when the boards sit under 30 cm.
How many 300 mm tiles cover a square metre?
One 300 mm square is 0.09 m², so ten tiles are 0.9 m² and you need about eleven full tiles for 1 m² before offcuts. The Nicoman 10-packs are that 0.9 m² if the tile matches the title. The Airsell colour name states 0.81 m² for nine tiles. The 40-pack is about 3.6 m². Measure a delivered tile, because a nominal 30 cm square can be cut slightly smaller.
Can these tiles hold a hot tub?
Nicoman’s bullets say the tiles are not suitable for heavy loads. A hot tub is named in the title and no filled weight is given, so the pack is not a spa base. The Airsell page and the modular kit do not state a design load either. A tub belongs on a base designed for that weight, which these listings do not provide.
Which pack is a trial and which is a real area?
The Nicoman 10-packs at £28.99 and £32.99, and the Airsell nine-pack at £36.00, each cover under 1 m². That is a sample or a very small patch. The 40-pack at £119.99 is the quantity pack, about 3.6 m², and it is the same light-grey tile as the £28.99 pack. Check the colour on a 10-pack before you rely on a second carton.
