At Outside Structures, we’ve seen a huge rise in demand for louvred or “bioclimatic” pergolas across the South of England. These sleek aluminium structures, with their adjustable roof slats, are designed for year-round outdoor living, keeping out the rain, shading you from harsh sun, and creating a modern space that feels like a natural extension of your home. 

But before committing to one, many homeowners ask the same question: do I need planning permission for a pergola in England? The answer depends on where you live, the size of your structure, and whether your property falls under special rules such as conservation areas or listed buildings.

Do Pergolas Need Planning Permission in England?

For many properties, a pergola can fall under permitted development (PD) rights, meaning you may not need formal planning permission. However, PD rights only apply if the structure meets certain conditions:

·      It must not extend beyond the front of the house.

·      The maximum height is generally 2.5m if within 2m of a boundary, or up to 4m if further away.

·      The structure should not take up more than 50% of your garden area (including other outbuildings).

·      If your louvred pergola is freestanding, modest in size, and compliant with these rules, you may not need to apply.

When Planning Permission Is Required

There are situations where a bioclimatic pergola does require permission:

·      Conservation areas: Local councils are stricter about external changes that alter the character of historic neighbourhoods.

·      Listed buildings: Any alteration, even in the garden, usually requires consent.

·      Commercial projects: For pubs, restaurants, or hotels, a formal application is normally required.

Bioclimatic Pergolas vs Traditional Pergolas

Unlike a simple timber frame, a bioclimatic pergola is a permanent, engineered structure. With motorised roof slats, integrated drainage, and options for side screens or heating, it often feels more like a veranda or garden room than a decorative feature. Because of this, planning departments may treat them differently. 

Practical Tips Before You Buy

·      Check your local planning authority’s website or speak to us, we’re used to advising clients across Cambridgeshire, Hertfordshire, Essex, and beyond.

·      Think about placement: Freestanding pergolas are usually easier than wall-mounted models.

·      Use an experienced installer: At Outside Structures, we’ll help you choose a design that meets both your needs and planning rules.

Why It’s Worth Doing Properly

Getting the planning side right is about more than ticking boxes, it ensures your investment is secure, adds long-term value, and avoids disputes later.
