Decking is one of the most popular garden features in London — and the first decision is always the same: composite or timber? Both have their strengths. Here is an honest comparison based on real-world performance in South East London gardens.
Composite Decking
Composite decking is made from a blend of wood fibres and recycled plastic. It is engineered for durability and low maintenance.
Maintenance: Virtually none. No annual oiling, sanding or staining. Just wash occasionally.
Durability: Resists rot, warping, fading and insect damage. Handles London rain and frost without deteriorating.
Appearance: Consistent colour and texture. Available in a wide range of finishes including wood-grain effects.
Cost: Higher upfront cost than softwood timber, but significantly lower lifetime cost due to zero maintenance.
Lifespan: 25–30 years with no maintenance.
Timber Decking
Timber decking uses natural wood — either softwood (pine, larch) or hardwood (iroko, ipe, cedar).
Maintenance: Annual oiling required for hardwood. Softwood needs staining every 1–2 years.
Durability: Hardwood is very durable if maintained. Softwood is less durable and prone to rot, warping and algae growth.
Appearance: Natural warmth and character that many homeowners love. Ages to a silver-grey if left untreated.
Cost: Softwood is the cheapest option upfront. Hardwood costs similar to composite but requires ongoing maintenance investment.
Lifespan: Softwood: 10–15 years. Hardwood: 20–25 years (with maintenance).
Our Recommendation for London Gardens
For most London gardens, we recommend composite decking. London weather — frequent rain, frost cycles, limited sun — is tough on timber. Composite handles it effortlessly and looks consistently good without any annual maintenance.
Hardwood timber is a beautiful choice for clients who enjoy the natural look and are committed to annual oiling. We use iroko and cedar for these projects — both age beautifully when properly maintained.
We avoid softwood decking for London gardens. The maintenance burden is too high and the lifespan too short to justify the initial saving.
