- Hardwood wins on: Appearance (real grain vs simulation), longevity (40–60 yrs vs 20–30 yrs), sustainability (natural renewable vs plastic-based), repairability, and whole-life cost over 40+ years.
- Composite wins on: Less cleaning needed in heavily shaded algae-prone positions, consistent manufactured appearance, and slightly easier installation for some hollow-board systems.
- Cost comparison: Premium composite £100–£160/m² installed. Yellow Balau hardwood £98–£150/m² installed. Comparable upfront — hardwood cheaper whole-life at 40 years.
- Sustainability: FSC/PEFC certified hardwood stores carbon. Composite is 50–70% recycled plastic — energy-intensive to produce, difficult to recycle at end of life.
- Our honest verdict: For any buyer who cares about natural appearance, sustainability, or buying once for life — hardwood is better. Composite's sole practical advantage is reduced algae cleaning in specific conditions.
The hardwood versus composite decking debate is one of the most common pre-purchase questions in the UK decking market — and one where composite manufacturers have dominated the narrative for a decade with marketing claims that deserve closer examination. This guide compares hardwood decking (Yellow Balau, Jatoba, ThermoWood) against composite decking honestly across every criterion that matters: cost, service life, appearance, maintenance, sustainability, and repairability. We sell natural timber including Jatoba, ThermoWood, and other naturally durable species. We do not sell composite. We will tell you exactly where composite has a genuine advantage and where the claims made for it do not hold up.
Natural hardwood decking versus composite — the difference in appearance, grain character and material authenticity is immediately visible. Hardwood is a natural renewable material with a 40–60 year service life. Composite is a plastic-based manufactured product with a 20–30 year realistic life.

Appearance — Why No Composite Looks Like Real Hardwood
Composite manufacturers have invested significantly in improving the visual simulation of natural timber grain in their products. Some premium composites are better-looking than they were a decade ago. But no composite currently available replicates two fundamental characteristics of real hardwood decking: the natural colour variation between boards, and the depth and three-dimensionality of genuine timber grain.
Composite boards are manufactured in batches — typically three to five repeating grain patterns that cycle across the deck. Once you know to look for the repeat, you see it. Natural hardwood boards are each unique — no two are identical in colour, grain character, or knot detail. The visual richness of a Yellow Balau or Jatoba deck comes precisely from this variation. It looks like the natural material it is, not a simulation of one.
Additionally, composite boards in direct summer sun can reach surface temperatures of 50–65°C in UK conditions — uncomfortably hot for bare feet. Natural timber stays significantly cooler in equivalent conditions due to lower thermal conductivity.
The Maintenance Argument — What Composite Marketing Claims vs Reality
The primary marketing claim for composite decking is zero or minimal maintenance. This deserves honest examination, because the claim is partially true and partially misleading.
What is true: Composite decking does not require annual oiling or preservative treatment. For wood-fibre composite, the plastic binder means the wood component cannot rot in the traditional sense. This is a genuine advantage in specific conditions — particularly on heavily shaded north-facing decks in humid positions where algae accumulates rapidly and annual cleaning is genuinely burdensome.
What is not consistently true: Premium composite still requires regular cleaning — composite manufacturers recommend cleaning two to four times per year in shaded positions. Composite decks accumulate algae, moss, and staining from food and drink just as natural timber does. The claim of zero maintenance is marketing language, not a practical reality. And composite cannot be sanded, oiled, or refinished — when it deteriorates, it deteriorates permanently.
The honest comparison: For a south-facing deck in good light with annual brushing, natural hardwood requires no more maintenance effort than composite. For a heavily shaded north-facing deck where green algae accumulates rapidly, composite may require marginally less frequent cleaning. This is the one genuine practical advantage composite holds — and it applies to a minority of UK garden decks.
Sustainability — Hardwood Wins Clearly
Composite decking is frequently marketed as a sustainable choice because it uses recycled plastic and wood waste. This narrative requires scrutiny:
- Composite composition: Typically 50–70% recycled polyethylene (HDPE) or PVC plastic and 30–50% wood fibre. The plastic component is derived from fossil fuels regardless of its recycled status — it is not biodegradable and cannot be composted
- Manufacturing carbon: Processing plastic and wood fibre into composite boards is significantly more energy-intensive than sawing and drying natural timber boards
- End of life: Composite boards cannot be meaningfully recycled at end of life in the UK — the wood-plastic blend makes separation impractical, and most composite decking ends its life in landfill or incineration
- Service life: A composite deck replaced after 20–25 years doubles the manufacturing carbon impact compared to a hardwood deck lasting 40–60 years
By contrast, FSC/PEFC certified hardwood decking is a natural renewable material that sequesters atmospheric carbon during the tree's growth, stores that carbon for its entire service life, and is genuinely biodegradable at end of life. For any project where sustainability credentials form part of the specification — increasingly common on residential and commercial projects — certified natural timber is the stronger choice.
Cost — Premium to Premium, Hardwood Wins Long-Term
| Specification | Installed cost/m² | Service life | 40-yr cost/m² |
|---|---|---|---|
| Budget composite | £60–£80 | 10–15 years | £180–£320 (2–3 replacements) |
| Premium composite | £100–£160 | 20–25 years | £200–£320 (1–2 replacements) |
| ThermoWood | £88–£145 | 25–40 years | £88–£145 (no replacement) |
| Yellow Balau hardwood | £98–£150 | 40–60 years | £98–£150 (no replacement) |
| Jatoba hardwood | £108–£165 | 40–60 years | £108–£165 (no replacement) |
Premium composite at £100–£160/m² installed requires replacement after 20–25 years. The replacement adds another £100–£160/m² — making the 40-year cost £200–£320/m². Yellow Balau hardwood at £98–£150/m² installed requires no replacement for 40–60 years. The 40-year cost is £98–£150/m². Hardwood is cheaper whole-life at every price point in the premium range. The only composite that appears cheaper over 40 years is budget composite — and budget composite typically underperforms on appearance, longevity, and surface quality versus Class 1 hardwood.
We sell natural timber and believe it is the better specification for most UK gardens — including our Siberian larch decking, ThermoWood decking, and our Yellow Balau decking range. But composite decking makes genuine sense in two specific situations: heavily shaded north-facing decks in humid positions where algae accumulation is a persistent cleaning problem, and situations where timber-look appearance is wanted but the client has documented inability to carry out any maintenance whatsoever. Outside these situations, natural timber — hardwood, ThermoWood, or larch — is the better specification on every criterion that matters.
Is hardwood decking better than composite?
Yes for most UK gardens — better appearance (natural grain vs simulation), longer service life (40–60 yrs vs 20–30 yrs), better sustainability (natural renewable vs plastic-based), easier repair, and cheaper whole-life at 40 years. Composite's sole genuine practical advantage is reduced algae cleaning in heavily shaded positions.
How does the cost of hardwood decking compare to composite?
Premium composite £100–£160/m² installed. Yellow Balau hardwood £98–£150/m². Comparable upfront. Over 40 years, hardwood wins — composite needs 1–2 replacements (adding £200–£320/m² total), hardwood needs none (£98–£150/m² total).
Does hardwood decking last longer than composite?
Yes — Class 1 hardwood lasts 40–60 years. Premium composite 20–30 years. Budget composite 10–15 years. Hardwood is the longer-life specification at every price point.
Is hardwood or composite decking more sustainable?
FSC/PEFC certified hardwood is more sustainable. It is a natural renewable material that stores carbon, is biodegradable at end of life, and requires no plastic components. Composite is 50–70% recycled plastic — manufacturing is energy-intensive, and composite cannot be meaningfully recycled at end of life.
