In the UK, planning permission is required for various types of building projects. The need for planning permission depends on the specifics of the project, including its size, purpose, and location.

To determine if your specific project requires planning permission, you should:

  • Consult Your Local Planning Authority (LPA): They can provide guidance specific to your area and project.
  • Use the Planning Portal: The UK Government’s Planning Portal offers comprehensive information and an interactive tool to check if you need planning permission.

It’s always a good idea to seek advice early in your project planning to avoid potential legal issues and ensure a smooth building process.

Here are some key scenarios when planning permission is typically required:

  • Significant Extensions and Alterations: If you are planning a large extension that exceeds certain size limits, such as adding more than 50% of the original house size or extending beyond specified height limits, planning permission is usually required.
  • Changing the Use of a Building: If you intend to change the use of a building (e.g., converting a residential property into a commercial space), you will need planning permission.
  • Listed Buildings and Conservation Areas: Any work on listed buildings or properties in conservation areas generally requires planning permission. This includes internal and external alterations, extensions, and sometimes even minor changes.
  • New Builds: Building a new house or other standalone structures typically requires planning permission.
  • Demolition: Demolishing buildings or parts of buildings, especially in conservation areas or for listed structures, often requires planning permission.
  • Changes to Roofs and Loft Conversions: Significant changes to the roof, including dormer windows or roof extensions, usually require planning permission, particularly if they exceed specified limits and conditions.
  • Installing Balconies or Raised Platforms: Adding balconies, raised platforms, or terraces often needs planning permission due to privacy and overlooking concerns.
  • Building in Designated Areas: If your property is in a designated area (e.g., national parks, Areas of Outstanding Natural Beauty), stricter rules apply, and you may need planning permission for projects that wouldn’t require it elsewhere.
  • Non-Residential Extensions: Extending non-residential buildings, like offices or shops, typically requires planning permission, especially if it involves significant changes in size or appearance.
  • High Fences or Walls: Erecting fences, walls, or gates over a certain height (usually 1 meter next to a highway or 2 meters elsewhere) usually requires planning permission.

For more detailed information on when planning permission is required and how to apply, you can visit the UK government’s planning permission guidance and the Planning Portal websites​ (Gov UK)​​ (Planning Portal)​​ (Planning Portal)​​ (Planning Portal)​.

Josh and his team have worked on several projects at our house, not least a new flat roof and large lantern. The boys were very friendly and polite - and importantly neat and tidy! Costings were very reasonable and work was carried out on time. It was also great that Josh was always available for a chat - unlike some contractors we have used in the past.

Absolutely thrilled with the work completed by Primary Construction on our 2-storey extension! From start to finish, the team was professional, reliable, and highly skilled. They built a beautiful space for us, complete with stunning bifold doors and a modern kitchen that perfectly blends with our home's style. The attention to detail was outstanding, and the quality of craftsmanship exceeded our expectations. They also kept the site tidy and adhered to timelines, which made the entire process smooth and stress-free. Highly recommend Primary Construction for any building project!

Right from the outset Josh was warm, friendly and reassuring. His project planning was timely and professional. The build quality and detail of his work of the interior improvements were first class from beginning to the end. His team were always friendly and polite and very clean and tidy. My experience was very positive and the cost was in line with the budget. Highly recommended

I recently had an extension built by Primary Construction, and I couldn't be happier with the results. From start to finish, their team was professional, efficient, and highly skilled. They worked with precision, ensuring every detail was completed to the highest standard.

The quality of the workmanship is outstanding, and the extension blends seamlessly with the existing structure. The team was always punctual, kept the site clean, and communicated clearly throughout the process, keeping me informed at every stage.

Not only did they complete the project on time, but they also stayed within budget with no hidden surprises. Their attention to detail and commitment to excellence truly set them apart. I highly recommend Primary Construction to anyone looking for top-quality building work – they exceeded all my expectations!

Thank you for an amazing job!

I called Josh at Primary Construction to do some work at my house. After a thorough consultation with him and the team, the work was quoted and carried out on time and within the budget we agreed. I’d have no hesitation recommending Josh and his team for any building work. A pleasure from start to finish
