Buy 4.8m Composite Decking Boards

4.8m boards mean fewer joins across a long deck, which looks better and leaves fewer board ends needing support underneath.
Worth the extra handling if your deck runs long in one direction. For a smaller or squarer deck, 3.6m composite decking boards usually waste less — and composite vs timber explains the material.
Seven colours in the 4.8m length at £34 a board. Choose 4.8m when the deck is between 3.6m and 4.8m deep, or when you want a long run without a butt joint every 3.6m: a 4.8m by 4m deck is 28 boards laid full length with no joins across it. The boards are the same profile as the 3.6m: hollow composite, reversible grooved and woodgrain faces, fixed with hidden clips at 350mm joist centres, ten-year warranty.
They are heavier to handle and need a straight route through the house or a side gate, so check access before you order. Matching 4.8m L-trim and step edge finish the long side without a join. The subframe guide covers spans and joist spacing for a deck this size, and free samples come in every colour. Free delivery over £190, 2 to 4 working days.

Frequently asked questions
How much is a 4.8m composite decking board?
£34 a board, the same £46 per square metre as the 3.6m length, in seven colours. Same 150mm by 25mm hollow reversible profile, same hidden clips and ten-year warranty.
When should I choose 4.8m boards?
When the deck is between 3.6m and 4.8m deep, or when you want a long run without a butt joint every 3.6m. A 4.8m by 4m deck is 28 boards laid full length with no joins across it.
Can I get 4.8m boards through the house?
Only with a straight route; they do not turn a corner in a hallway. Check side-gate access before you order. Delivery is kerbside by pallet, so plan the carry from the road.
Do the trims come in 4.8m too?
L-trim and step edge come in 4.8m lengths so the long side of the deck finishes without a join. Fascia boards are 3.6m; two cover a 4.8m side with one join.
