Installing a new garden shed is one of the most practical ways to improve your outdoor space. But before choosing the size, style or layout, many homeowners ask an important question:
Do I need planning permission to install a shed in my garden?
In most cases, the answer is no — but there are some important rules you need to be aware of before installation begins.
At The Shed Factory, we regularly help customers across London and the South East understand what is and isn’t permitted.
When Planning Permission Is NOT Required
Most garden sheds fall under what’s known as permitted development. This means you can install a shed without applying for planning permission, as long as certain conditions are met.
Typically, planning permission is not required if:
-
The shed is for domestic use only
-
It is located in your back garden
-
It does not take up more than half of your outdoor space
-
It is not positioned in front of your house
-
The structure is single storey
As long as your shed meets these guidelines, you can usually proceed without involving your local council.
Shed Height Restrictions
One of the most important factors is height.
Your shed should generally be:
-
No taller than 2.5 metres if placed close to a boundary
-
No taller than 4 metres with a dual-pitched roof
-
No taller than 3 metres with any other roof type
Keeping within these limits helps ensure the building complies with permitted development rules.
Distance From Boundaries
If your shed is within 2 metres of your boundary line, the maximum height is normally limited to 2.5 metres.
This applies to:
-
Fences
-
Garden walls
-
Property boundaries
Professional positioning during installation helps avoid future issues.
Special Rules for Certain Properties
Some properties may have additional restrictions.
You may need planning permission if:
-
You live in a listed building
-
Your property is in a conservation area
-
Your home is on designated land
-
The shed is intended for sleeping accommodation
If you're unsure, it's always worth checking with your local authority before proceeding.
Why Professional Installation Still Matters
Even if planning permission isn’t required, correct installation is essential.
A properly installed shed should:
-
Sit level
-
Be supported by a suitable base
-
Allow for drainage
-
Remain structurally stable
Many of our customers choose modern ground screw base systems to ensure their shed remains secure without the need for traditional concrete foundations.
This provides excellent support while minimising ground disturbance.
Avoiding Common Mistakes
Some of the most common issues we see include:
-
Sheds installed too close to boundaries
-
Incorrect height selection
-
Poorly prepared ground
-
Inadequate foundations
Planning ahead helps you avoid costly adjustments later.
