Composite Fencing vs Wood Fencing: Which Is Better?
Composite fencing costs more upfront (roughly £120–£240 per panel versus £20–£60 for timber) but needs virtually no maintenance and typically carries 10–25-year warranties, against 10–15 years of average service life for pressure-treated softwood panels that also need re-staining every 2–3 years. Timber remains cheaper to buy, easier to repair piecemeal, and — if FSC-certified — comes from a renewable, carbon-sequestering resource. Which wins depends on whether you're optimising for lowest purchase price or lowest total cost and effort over 15–20 years.

What's actually different about the two materials?
Timber fencing is solid wood — usually pressure-treated softwood in the UK, built as lap (overlap), closeboard/feather-edge, or panel fencing to specifications such as BS 1722-11 (prefabricated wood panel fences) or BS 1722-5 (close-boarded and wooden palisade fences). Performance depends on species, preservative treatment and how well the posts are set.
Composite fencing is an extruded profile made from a blend of wood fibre and thermoplastic (typically recycled HDPE or polypropylene), covered in the UK/EU by BS EN 15534-6:2015+A1:2017, which specifically covers fencing profiles and elements (the decking and cladding parts of the same standard family are BS EN 15534-4 and -5 respectively). EnviroBuild’s composite fencing ranges use recycled wood fibre and plastic; Slatted adds a protective cap for extra fade and stain resistance, while uncapped range exposes more of the wood-fibre surface.
How much do composite and wood fencing cost — upfront and over time?
Timber is cheaper to buy. UK trade pricing guides put lap/overlap panel material at roughly £20–£50 each, closeboard/feather-edge at £25–£60, installed at £70–£130 per linear metre depending on style. Composite panels run roughly £120–£240 each, installed around £130–£200 per metre — 2–4x the material cost of basic timber.
The gap narrows once you factor in upkeep. Timber typically needs re-staining, oiling or painting every 1–3 years at around £170–£270 per treatment (materials and labour), plus the cost of replacing individual rotted panels or posts before the fence line as a whole needs replacing. Composite needs none of that. Over a 15–20-year span, a timber fence that's re-treated every two years and has a panel or two replaced can approach or exceed composite's higher purchase price — but the arithmetic depends heavily on whether you'd pay a contractor for that maintenance or do it yourself.
Labour quotes vary widely between sources (some quote £40–£100 per panel), so treat any single figure as a starting point and get a local quote rather than budgeting off a published average.
How much maintenance does each type actually need?
Timber fencing: Needs re-staining, oiling or painting roughly every 1–3 years to maintain water repellency and colour. Even with treatment, individual panels or posts in contact with damp soil can rot and need replacing well before the rest of the fence line does.
Composite fencing: No sanding, staining, painting or sealing. EnviroBuild and other manufacturers recommend an occasional wash with water and mild detergent; capped ranges resist algae and mould better than uncapped ones.
Fence posts are usually the weak point for timber, since they sit in or near the ground where moisture and soil organisms concentrate. The Wood Protection Association recommends timber posts in ground contact are treated to Use Class 4 under BS EN 335, and the current UK treatment code of practice is BS 8417; posts treated to a lower use class or left untreated fail years earlier than the panels they support. Composite fence panels often use either aluminium posts or steel post stands that fix into the ground to ensure much longer term durability.
How durable and weather-resistant is each material?
Timber’s resistance to fungal decay is graded under BS EN 350 (Durability Class 1 “very durable” to DC5 “not durable”); most softwoods used for fence panels sit in DC4–DC5 and rely on preservative treatment rather than natural durability. Untreated softwood can fail in as little as 5–7 years; well pressure-treated softwood typically lasts 10–15 years, with premium treatments and favourable conditions pushing that toward 25 years or more.
Composite fencing doesn't face the same fungal decay pathway, because the wood fibre is encased in plastic, so it isn't rated under BS EN 350 at all — it's assessed under BS EN 15534-6 for mechanical performance and weathering instead. Manufacturers commonly claim 25+ year service life for composite fencing, and EnviroBuild backs its ranges with warranties of up to 15 years (Explorer) and up to 25 years (Frontier) at the time of writing. As with decking, a warranty is a defined manufacturer commitment, not a guarantee the fence will last exactly that long in every site condition.
How does the appearance change over time?
Unfinished or lapsed-maintenance timber greys and can develop surface checking, splitting or algae growth within a season or two. Re-stained or painted timber holds its colour for roughly 1–3 years before needing refreshing, and panels weather unevenly depending on sun and rain exposure, which can make repaired sections visually mismatched.
Composite fencing is colour-through or capped at manufacture, so the colour doesn't need refinishing — capped type boards resist UV fade for longer than uncapped ranges. Uncapped composite can show cosmetic tannin leaching (temporary lightening or streaking) in the weeks after installation as residual wood extractives wash out; this is not a durability issue and stops on its own, consistent with EnviroBuild's composite guidance for the same material family.
Which has the lower environmental impact?
As with decking, this depends heavily on which claim you're comparing and over what timeframe.
Composite fencing uses recycled input material — EnviroBuild states its uncapped range is around 87% recycled and capped around 90% — which diverts plastic and wood waste from landfill, and its Hyperion composite products are manufactured using 100% wind-generated electricity. EnviroBuild also states that its Hyperion Explorer decking has 64% lower global warming potential than equivalent timber decking, based on its own life-cycle assessment (which weighs manufacturing energy, avoided treatment and replacement cycles together, not any single factor alone). That figure is specific to decking, not independently published for fencing, so it's worth treating as directional rather than a verified fencing number.
Timber fencing, when FSC- or PEFC-certified, comes from a renewable, biodegradable resource, and growing timber sequesters carbon — a genuine benefit a plastic-containing composite can't fully replicate. Preservative treatment chemicals and the shorter replacement cycle (meaning more timber consumed per decade of service) work against timber's carbon story to some degree, but we found no fencing-specific, third-party-reviewed life-cycle assessment comparing the two materials directly — general LCA literature on WPC vs. treated lumber decking exists, but its assumptions about lifespan and disposal don't transfer cleanly to fence panels without adjustment. Treat any single "carbon footprint per metre" figure from either camp with caution unless it links to a published, third-party-reviewed LCA specific to fencing.
Composite is also harder to recycle at end of life than clean, untreated timber, because it's a bonded wood-plastic blend, so offcuts likely have to go into the general waste stream.
Which one should you choose?
Choose timber if minimising upfront spend matters most, you're comfortable with (or enjoy) periodic re-staining, you want the option to replace single damaged panels cheaply, or you specifically want an FSC-certified, biodegradable material.
Choose composite if you want to install once and largely forget about it for 15–25 years, you dislike the recurring cost and effort of staining/painting, or you're prioritising recycled-content material over natural biodegradability.
FAQ
Does composite fencing rot like wood?
No, not in the same way. The wood fibre in composite fencing is encased in plastic, denying fungal decay organisms the substrate they need to rot solid timber. Surface algae or mould can still form in damp, shaded spots, but cleaning removes it.
How often does a timber fence need re-staining?
Most UK guidance recommends re-staining, oiling or painting every 1–3 years to maintain water repellence and colour; skipping this accelerates surface checking and, eventually, rot.
Is composite fencing actually cheaper in the long run?
Composite costs more to buy (roughly £120–£240 per panel versus £20–£60 for timber) but avoids the recurring cost of re-treatment and panel/post replacement over a 15–20-year period. Whether it works out cheaper overall depends on how much maintenance you'd otherwise pay someone to do and how long your timber fence actually lasts in practice.
What UK/EU standard covers composite fencing?
BS EN 15534-6:2015+A1:2017 covers wood-plastic composite and natural fibre composite fencing profiles and elements specifically. Timber fence panels are separately specified under BS 1722 (various parts for panel, closeboard and post-and-rail fences), with preservative treatment governed by BS 8417 and BS EN 335 use classes.
How long do timber fence posts last compared with panels?
Posts usually fail before panels because they sit in or near the ground. Untreated posts can fail in 5–7 years; properly pressure-treated posts (Use Class 4) typically last 10–15 years, with premium treatments claimed to extend that toward 25 years.
Can composite fencing be recycled at the end of its life?
It's harder to recycle than clean, untreated timber because it's a bonded wood-plastic blend. Check with your supplier or local waste facility for take-back routes, as these aren't standardised across the industry.
