Most pergolas in the UK do not require planning permission, provided they meet permitted development rules on height, placement, and use. However, there are important exceptions depending on your property type, location, and pergola design — especially for larger aluminium pergolas.
This guide explains exactly when you need permission, when you don’t, and how to avoid costly mistakes.
When Do Pergolas NOT Need Planning Permission?
In most cases, planning permission is not required if your pergola:
-
Is no higher than 2.5 metres
-
Is located at the rear or side of your property
-
Is not fully enclosed
-
Is not attached to a listed building
-
Is not in a conservation area (or meets local rules)
Most modern aluminium pergolas fall within these limits, making them a popular choice for UK gardens.

When IS Planning Permission Required?
You may need planning permission if:
-
The pergola exceeds 2.5m in height
-
It is installed at the front of your property
-
It is fully enclosed with walls or glazing
-
Your home is listed or in a conservation area
-
The pergola is intended for commercial use
If you’re unsure, always check with your local council before installation.
Are Aluminium Pergolas Treated Differently?
No — aluminium pergolas follow the same planning rules as timber pergolas. However, aluminium offers major advantages:
-
Cleaner, modern appearance (often favoured by planners)
-
No warping or deterioration over time
-
Slim profiles that help stay within height limits
This makes aluminium pergolas easier to keep compliant long-term.
Do I Need Building Regulations Approval?
Generally, no — pergolas are not classed as habitable structures.
However, electrical work (lighting or heaters) must be installed safely and may require a qualified electrician.
Final Advice Before Buying a Pergola
