Timber Decking Regulations

An outdoor timber deck can transform your garden space, adding both visual appeal and practicality. However, it's crucial to be aware of the various planning and building regulations in the UK that apply before you embark on your decking project. Let’s take a look at some of the essential regulations you need to be aware of to help you install your decking with confidence and compliance.

Understanding timber decking planning permissions

Install with confidence 

While natural outdoor decks are generally seen as permitted developments not requiring planning consent, there are exceptions based on your location in the UK. It’s important to note that regulations can frequently change, so we always recommend consulting with your local council or planning office before starting your decking project.

Here are some of the common situations where planning is required for an outdoor timber decking project:

  Deck height: If the deck platform is over 30cm above the ground.

  Garden coverage: When decks or other structures cover more than 50% of your garden area.

  Proximity to highways: If the deck is within 20 meters of a highway.

  Impact on neighbours: The deck should not affect the amenity value or privacy of neighbouring properties.

  Heritage and conservation areas: Extra care is required if the deck is attached to a listed building or located in a conservation area or National Park.

Preventing planning problems

For natural timber decks that are not simple, low-level structures, it's wise to contact your local council's planning department for advice. This step is crucial, especially if your project falls into any of the above categories.

Consulting neighbours

Engaging with neighbours who might be impacted by your garden decking is also an essential step. Neighbour objections are a common reason for planning refusals or approval conditions. Early consultation can prevent mid-construction complaints and intervention by the local council.
