Do You Need Pergola Planning Permission in the UK?

Understanding UK Planning Rules for Pergolas

If you’re thinking about adding a pergola to your garden in London—or anywhere else in the UK—you may be wondering whether you need planning permission. It’s a common concern, and the answer depends on a few key factors such as height, location, and whether your property is listed or in a conservation area.

When You Don’t Usually Need Planning Permission

In most cases, pergolas fall under what’s known as “permitted development.” This means you can install one without formal planning approval as long as:

• The pergola is no taller than 2.5 metres if placed within 2 metres of your boundary

• The structure is not on a listed property or within a designated conservation area

• It is used for domestic purposes only (not commercial)

• It does not cover more than 50% of your garden area

At Casa Pergola, most of our installations—especially the popular Moderna range—comply with these guidelines.

When You Might Need Planning Permission

There are cases where you’ll need to apply:

• If your home is listed or in a conservation area (common in parts of London like Hampstead or Richmond)

• If your pergola design is particularly large or elaborate

• If you’re planning to install a structure close to a neighbour’s boundary and it exceeds height limits

If you’re unsure, we can advise during your free consultation.

Why Aluminium Pergolas Are Ideal for London Gardens

Aluminium pergolas—especially our custom designs—offer a clean, modern look while complying with most local planning rules. With their sleek design and minimal visual intrusion, they’re often more likely to meet planning guidelines than bulkier timber structures.

What About sliding glass walls and Zip Blinds?

Adding features like sliding glass walls or Zip Blinds to your pergola doesn’t usually require separate permission if the structure remains open‑sided. However, enclosed or fully glazed garden rooms might fall under different rules. We always advise clients on‑site before installation to make sure everything is compliant.
