Aluminium vs Timber Pergolas
When choosing a pergola for a UK garden, the decision often comes down to aluminium vs timber. While timber pergolas can look attractive initially, aluminium pergolas are increasingly preferred by UK homeowners due to their durability, low maintenance, and ability to withstand wet weather.
This guide compares aluminium and timber pergolas honestly, helping you decide which is best for your garden, budget, and long-term expectations.
Aluminium Pergolas: Pros & Cons
Advantages of Aluminium Pergolas
Aluminium pergolas are engineered for performance in challenging climates like the UK.
Key benefits include:
-
Rust-free, powder-coated frames
-
Excellent resistance to rain, wind, and temperature changes
-
Minimal maintenance — no staining or repainting
-
Long lifespan (often 15–25+ years)
-
Clean, modern appearance
-
Optional upgrades such as LED lighting, heaters, and screens
Because aluminium doesn’t absorb moisture, it remains structurally stable year after year.

Disadvantages of Aluminium Pergolas
-
Higher upfront cost than basic timber pergolas
-
More contemporary look (may not suit very traditional properties)
However, these drawbacks are often outweighed by reduced maintenance costs over time.
Timber Pergolas: Pros & Cons
Advantages of Timber Pergolas
Timber pergolas are often chosen for:
-
Natural appearance
-
Traditional garden aesthetics
-
Lower initial purchase price
They can suit certain heritage or countryside settings when well maintained.
Disadvantages of Timber Pergolas (UK Climate)
In the UK’s damp climate, timber pergolas often require significant upkeep.
Common issues include:
-
Rot, warping, or cracking over time
-
Regular staining or painting required
-
Moisture absorption leading to reduced lifespan
-
Ongoing maintenance costs
Without consistent treatment, timber pergolas can deteriorate far faster than aluminium alternatives.
