In the UK there is a fantastic resource called Planning Portal. It helps with questions about planning permission and offers illustrated diagrams to make things easier to understand. There is a dedicated section for decking. As of November 2016 these are the basic facts:
Putting up decking, or other raised platforms, in your garden is permitted development, not needing an application for planning permission, providing:
- The decking is no more than 30cm above the ground
- Together with other extensions, outbuildings etc, the decking or platforms cover no more than 50 per cent of the garden area.
Please note: The permitted development allowances described here apply to houses and not to:
- Flats and maisonettes (view our guidance on flats and maisonettes)
- Converted houses or houses created through the permitted development rights to change use (as detailed in our change of use section)
- Other buildings
- Areas where there may be a planning condition, Article 4 Direction or other restriction that limits permitted development rights.
The Planning Portal then goes on to discuss building regulations:
Building Regulations should be assumed to apply to every deck structure requiring planning permission.
If you are unsure about whether you are required to comply, you may wish to contact your local Building Control body.
As with all building control and building regulations you should contact your local building control department which is operated under the umbrella of your local council. Click here for a useful list of options regarding your permitted development rights.
Delivery of your decking:
One area that causes confusion is delivery of your decking – often many decking boards will be lifted off a flat bed truck. It is well worth ensuring that the road or public highway is not blocked during this delivery. Most suppliers will unload far faster than you imagined.
Importantly, you should also consider how the decking boards are going to get from the roadside to your garden:
- Do you have easy access to your garden or is it through the house (and front door)?
- Would a delivery have to be lifted over your house? If this is the case then you will need to speak to your decking supplier to ensure you do not block the public highway. Your supplier may also need specialist lifting equipment. There is a way to deal with this issue – order shorter decking boards! Most suppliers offer 2.2M lengths which deal with the issue of delivery.
- Is the ground level and stable where the delivery truck will be parked?
- Are you going to be at home and is delivery arranged within a specific timeframe? Often suppliers are making multiple drops and can be delayed due to unforeseen circumstances. Maybe you are delayed – your friend’s cat has been sick, you got stuck in traffic, late back from the school run?
- Always communicate with your supplier and have an agreed delivery plan. Be patient, this can take some organising and a good supplier will be accommodating during this process.
