When Do I Need Planning Permission for Decking?

The good news is that many decking projects don’t need planning permission. However, as with all home improvement projects, there are some important conditions to be aware of. This guide will take you through the regulations, so you can start your decking project with confidence.

Decking and Permitted Development Rights

In the UK, most small-scale decking projects can be built under Permitted Development (PD) rights, meaning that planning permission isn’t required. However, there are limits and conditions that apply to ensure the decking fits within the guidelines of PD. Here are some key rules to keep in mind:

1. Height Restrictions:

   • Your decking must be no more than 30cm (12 inches) above the ground level. This is probably the most crucial rule. If your decking exceeds this height, you will need to apply for planning permission.

2. Coverage and Area Restrictions:

   • Decking, combined with any other extensions or outbuildings, must not cover more than 50% of the total garden area. This means if you already have an extension, shed, or any other large feature in your garden, you may need to calculate the area to ensure you comply with this rule.

3. Proximity to Boundaries:

   • If your decking is near a boundary, such as the edge of your property where your neighbour’s garden begins, you may need to keep it low and consider any impact it could have on their privacy. Although PD rights allow some flexibility, a higher structure closer to a boundary might need planning approval.

When Planning Permission Is Required for Decking

In some situations, planning permission is always required for decking, regardless of the height or area covered. Here are the main circumstances when planning permission becomes necessary:

1. Listed Buildings:

   • If your property is a listed building, decking will require planning permission. Listed buildings have stricter rules to preserve their historical features, which means any addition—even in the garden—needs consent.

2. Conservation Areas:

   • If you live in a conservation area, National Park, or an Area of Outstanding Natural Beauty (AONB), your decking project may require permission. These areas have additional protections in place to preserve their character, and your local planning authority will need to approve any changes.

3. Elevated or Multi-Level Decking:

   • Planning permission is needed if you plan to install decking that has a height of over 30cm, or if the decking is on a multi-level platform. The height can significantly impact your neighbours’ privacy, which is why permissions are often required for elevated decking projects.

4. Balustrades and Railings:

   • If you want to add railings, balustrades, or fencing around your decking, planning permission may be required depending on the height. Any fencing over 2 metres needs permission, which may impact your decking plans if it’s necessary for safety.

How to Avoid Planning Permission Issues

If you’d like to install decking without having to apply for planning permission, here are some practical tips:

• Keep the Decking Low: Aim to keep the decking height under 30cm. This helps you stay within the guidelines for Permitted Development and reduces the likelihood of needing permission.

• Consider the Location: Avoid placing your decking in areas that directly overlook neighbours or affect their privacy. Keeping your decking in a position that doesn’t dominate the garden space or impose on others will help reduce any disputes.

• Measure Your Garden Space: Make sure you’re not exceeding the 50% rule of garden coverage, especially if you have other garden structures like sheds, greenhouses, or extensions.

Building Regulations for Decking

While planning permission may not always be required, you’ll also need to consider building regulations for your decking. These regulations ensure that the decking is safe, especially if it’s raised above ground level. Here’s what building regulations might require:

1. Safety Railings:

   • Decking that is more than 30cm above the ground should have railings to prevent falls. The railings must meet certain strength and height requirements to be compliant.

2. Load-Bearing Capacity:

   • Your decking must be strong enough to support weight safely. This means using the correct type and size of joists and posts to support the decking boards.

3. Access and Stability:

   • If you’re incorporating steps, these should be designed with proper handrails and a secure foundation to ensure safety. Stability is key, and anchoring the decking properly will ensure it stays safe for use.

Applying for Planning Permission

If you do need planning permission for your decking project, the process is straightforward:

1. Consult Your Local Planning Authority (LPA):

   • Start by contacting your Local Planning Authority. They’ll let you know whether planning permission is required and provide guidance on any specific requirements in your area.

2. Submit Your Application:

   • You can apply for planning permission online via the Planning Portal. You’ll need to provide detailed plans, measurements, and descriptions of the decking project. It generally takes around 8 weeks for a decision.

Benefits of Decking Without Planning Headaches

Adding decking can do wonders for your garden space, and getting it right from the start will save you potential headaches and costs later down the line. Here are a few reasons why decking is a great choice:

• Enhanced Outdoor Living Space: Decking creates a dedicated area for relaxing, entertaining, or dining, making the most of your garden during good weather.
• Aesthetic Appeal: Properly installed decking can significantly enhance the look of your garden, giving it a more modern and sophisticated appearance.
• Property Value: Decking can increase the kerb appeal of your home, potentially adding value when it’s time to sell, especially if it’s well-maintained and installed professionally.

FAQs About Decking Planning Permission

1. Do I need planning permission for decking next to my house?

   • Not usually, as long as your decking is under 30cm high and doesn’t cover more than 50% of your garden. It’s best to double-check with your Local Planning Authority to be certain.

2. Can I add decking to a flat or maisonette?

   • Generally, Permitted Development rights don’t apply to flats or maisonettes, which means you’re likely to need planning permission for any decking project.

3. How can I make my decking more private without planning permission?

   • You can install obscure glass panels or low-level trellis instead of fencing over 2 metres high, which may require permission.

When Do I Need Planning Permission For Decking

The question, “When do I need planning permission for decking?”, often depends on your unique circumstances, including the height of the decking, the area it covers, and where you live. Most decking projects that are low and cover less than half the garden can be completed under Permitted Development. However, if you’re in a listed building, conservation area, or are planning something more elaborate, you’ll need to apply for permission.

Adding decking is a fantastic way to bring more use and enjoyment to your outdoor space. If you’re considering installing decking and want to be sure that everything is in compliance, it’s always a good idea to double-check with your Local Planning Authority or speak to professionals like those at Surv Essex who can provide guidance every step of the way.
