How Do I Know If I Need Planning Permission for an Extension?

Thinking of expanding your living space with an extension? If you are, the big question might be how do I know if I need planning permission for an extension? Planning permission can be a complex topic, but breaking it down makes it easier to understand what’s required for your dream project to go ahead smoothly.

How Do I Know If I Need Planning Permission For An Extension?

Understanding Planning Permission for Extensions

Planning permission is official consent from your local council allowing you to carry out building work. Its primary aim is to ensure developments align with local planning policies and consider the impact on neighbours, traffic, and the environment.

When it comes to extensions, it’s not always straightforward—some projects need full planning permission, while others may fall under Permitted Development Rights, meaning they do not require formal consent.

Do You Always Need Planning Permission?

No, not always. Many smaller extensions may fall under Permitted Development Rights, which let you extend your property without seeking formal planning approval. Here are some basic conditions for an extension to be classified as Permitted Development:

  • Single-Storey Extensions: The extension must not extend more than three metres from the rear wall of a semi-detached property or four metres for detached houses.
  • Height Restrictions: The extension must not exceed four metres in height and must not be taller than the highest part of your existing roof.
  • Proximity to Boundaries: Extensions that are close to property boundaries must adhere to height and size limitations.
  • Use of Similar Materials: The extension must use materials similar to those of the existing property.

If your planned extension stays within these guidelines, it’s likely you won’t need formal planning permission. However, larger projects may require you to submit a planning application.

How Do I Know If My Extension Needs Planning Permission?

  • If you’re still wondering how do I know if I need planning permission for an extension, consider these steps to get a definitive answer:

    1. Check Permitted Development Rights: Your first port of call is to understand what’s allowed under Permitted Development. The rules can vary depending on the size and location of your property, so it’s worth looking at specific guidelines available on the Planning Portal website.

    2. Contact Your Local Council: Reach out to your local council’s planning department to discuss your project. They can give you an official view on whether planning permission is needed for your proposed extension.

    3. Work with a Professional: Consulting with professionals like Surv Essex can save you a lot of hassle. We provide extension plans that meet all planning and building regulations, and we can advise you from the very beginning about whether you need planning permission.

How to Check If Planning Permission Is Needed

If you’re still unsure and wondering how do I know if I need planning permission, these are the steps you should take:

  1. Use Your Council’s Planning Portal
    Most local councils in the UK offer planning permission guidance online. You can enter your property details and get an idea of what’s permitted and what will need official permission.

  2. Hire a Professional
    Engaging an architect or a planning consultant can be helpful. They will have a thorough understanding of planning rules and can tell you upfront if your project needs planning permission.

  3. Consult Building Control
    While planning permission and building control are different, consulting building control can sometimes highlight issues that may require planning permission. They oversee the safety aspects, and while their main role is to ensure work meets building regulations, they might also provide insight into planning requirements.

Common Factors that Require Planning Permission

There are some factors that commonly mean planning permission is required:

  • Two-Storey Extensions: If you’re planning to add two storeys, you will likely need planning permission.
  • Proximity to Boundaries: If your extension is planned to be very close to a neighbouring property, it’s probable that planning permission will be required.
  • Conservation Areas: Living in a Conservation Area? Permitted Development Rights may be restricted, meaning you will need to apply for planning permission even for modest projects.

Why It’s Important to Check Early

It’s critical to know whether you need planning permission before beginning any building work. Starting work without the necessary permissions can result in enforcement action from your local council, which might mean altering or demolishing the work done and could lead to fines. So, getting a clear answer to how do I know if I need planning permission for an extension before you pick up a hammer is crucial.
