Composite Decking Fitted in Sheffield

Composite is sold hard on the promise that you never have to do anything to it again. That is close to true compared with timber, but not quite true, and you are better hearing it now than discovering it in year three.

You will not be sanding, staining or oiling it. That is the real saving, and over fifteen years it is a substantial one in both money and weekends. What composite does still need is washing. In a city as green and as wet as Sheffield, decks pick up algae and a film of grime, particularly on north‑facing sections and anywhere overhung by trees. A wash down a couple of times a year keeps it looking like it did when it went down.

Wet composite can be slippery, in the same way wet timber is. Textured and grooved board surfaces help considerably, and keeping algae off helps more than anything else. If the deck will be used by anyone unsteady on their feet, tell us at design stage and we will talk through board finish and where handrails make sense.

The other honest point is fading. Early composite boards lightened noticeably in sunlight. Modern capped boards hold their colour far better, and most carry long manufacturer warranties covering it — but expect a slight settling of tone in the first year, which is normal rather than a fault.

Most decks do not need planning permission, but there is a threshold worth knowing before you settle on a design, because almost nobody mentions it at quote stage.

Under permitted development rules in England, a raised platform such as decking is generally allowed without an application provided it sits no more than 300mm above ground level, and that it and other buildings cover no more than half the land around the original house. Go above that 300mm and you may need permission — which matters in Sheffield more than most places, because on a sloping garden a deck that is flush with the back door can easily stand a metre or more above ground at the far end.

Separately, where there is a drop of more than 600mm from the deck edge, guarding is required under Part K of the Building Regulations, at the appropriate height. That is a safety requirement rather than an optional design feature, and it is the reason a raised deck quote should always include balustrades.

Overlooking is the other consideration. A raised deck that gives a clear view into a neighbouring garden or window is the most common cause of objections, and it is worth thinking about before rather than after.

We build decks, we are not planning officers — the above is the general position rather than advice on your property. Sheffield City Council can confirm where you stand, and we are happy to design to keep a deck within permitted development where that is what you want.

As a guide, composite decking supplied and fitted typically works out between £150 and £250 per square metre. That range covers the boards, the sub‑frame, the fixings, the edge detail and the labour to build it, rather than a board price with everything else added later.

Where a job lands within that range, or occasionally above it, comes down to a handful of things. A straightforward ground level deck on firm, flat ground sits at the lower end. A raised deck on a sloping garden needing a heavier frame, steps and balustrades sits at the upper end. These are indicative figures rather than a quotation — send us photos and measurements and we will give you a real one.
