You’ve found the perfect aluminium carport that is sleek, strong, and built to last. But before you hit the “buy now” button, one important question pops up:
Do I need planning permission to install aluminium carports?
In most cases, no but there are exceptions. Let’s walk you through exactly what the rules are in the UK, so you can start your project confidently, without stumbling into red tape.
Why Aluminium Carports Are So Popular?
Aluminium carports are a brilliant alternative to full garages. They’re quick to install, require barely any maintenance, and offer solid year-round protection against the unpredictable British weather.
They're also ideal for:
-
Driveway parking
-
Bicycle storage
-
Shaded patios
-
Work areas or outdoor workshops
Better yet, they often fall under permitted development rights, meaning no formal aluminium carport planning permission is required. But there are a few conditions to keep in mind.
When You Don’t Need Aluminium Carport Planning Permission?
You’re in luck if your property meets these standard criteria:
-
The carport is under 2.5m in height
-
It’s located behind the main front wall of your home
-
It covers less than 50% of your total garden or plot
-
It’s not in a conservation area, National Park or listed property
-
There’s no change to existing access points or the public highway
These rules are part of permitted development rights under UK planning law. They’re designed to allow homeowners to make practical improvements without jumping through hoops.
When You Need Aluminium Carport Planning Permission?
There are situations where you’ll need to go through your local authority for approval. These include:
-
Installing the carport in front of your home
-
The structure exceeds 2.5m in height
-
You live in a listed building or conservation area
-
The carport will sit close to a public road
-
It connects to the main building or modifies it in any way
Important:
Even if the carport is open-sided or temporary in appearance, once it’s fixed to the ground or a wall, it’s legally considered a permanent structure.
Why Choose Aluminium Over Timber or Steel?
Aluminium isn't just durable it’s incredibly low-maintenance. Here’s why it’s the smart choice for modern homeowners:
-
No rust, rot, or repainting
-
Lasts over 30 years
-
100% recyclable
-
Lightweight yet strong
-
Stylish finishes in grey, black, or wood-look coatings
According to Aluminium Federation UK, aluminium’s natural oxide layer protects it from the elements—making it ideal for outdoor applications like carports and verandas.
FAQs
1. Is a carport classed as an outbuilding?
Yes. In planning terms, carports are treated as outbuildings like sheds or greenhouses.
2. Can I put a carport on my driveway without permission?
If it meets the height and placement rules, yes. Always double-check if your area has special conditions.
3. How close to my neighbour’s fence can I build?
It’s usually okay if it’s under 2.5m high. For anything closer or taller, speak to your local planning office.
4. Does a carport increase home value?
Yes. A well-designed aluminium carport can improve kerb appeal and boost resale value especially in areas with limited parking.

Final Thoughts:

Probably not but don’t assume. If your structure fits within standard guidelines, you’re free to build. But always double-check with your local council, especially if your home is in a protected area or you’re planning something custom. One quick call now could save you time (and money) later.
