How much does a pergola cost?
Pergola cost depends on the material and whether it has a louvered roof. Get an indicative supply-and-fit figure below.
What a pergola involves
- 1Posts and base
Posts set in concrete (or on a patio) carry the frame — the structural part that keeps it stable.
- 2Frame and material
Timber is cheapest and warmest-looking but needs maintenance; aluminium is low-maintenance and modern.
- 3Roof options
An open frame gives shade and structure; a louvered or covered roof makes the space usable in the rain — for a higher cost.
A pergola defines and dresses an outdoor seating area, lifting garden photos on a sale for relatively little. Timber suits a traditional look on a budget; a louvered roof turns the space into an all-weather room — match the spend to the property.
Pergola costs (indicative)

|---|---|---|
| Timber (kit, DIY) | Open frame | £400 – £1,500 |

A base/posts set in concrete, plus the frame. Louvered-roof systems that keep the rain off cost the most.
