If you’re planning a home extension, converting a commercial property, or making changes under permitted development rights, understanding prior approval is essential. While some developments don’t require full planning permission, they may still need approval from your local planning authority before work can begin.
Navigating the planning system can be complex, and getting it wrong could lead to delays, additional costs, or enforcement action. At Planning Build, we help homeowners, landlords, developers, and businesses successfully navigate the prior approval process from start to finish.
What Is Prior Approval?
Prior approval is a planning process that applies to certain developments carried out under permitted development rights. Rather than requiring a full planning application, the local planning authority reviews specific aspects of the proposal, such as design, transport impacts, flood risk, noise, or the effect on neighbouring properties.
The exact matters considered depend on the type of development you’re proposing. You can read more about the process in the official UK government guidance:
When Do You Need Prior Approval?
Prior approval may be required for a range of developments, including:
- Larger home extensions
- Additional storeys on existing buildings
- Agricultural developments
- Certain changes of use
- Telecommunications equipment
- Some demolition projects
Every project is different, and qualifying for permitted development doesn’t automatically mean you can begin work immediately. Professional advice can help determine whether prior approval applies to your proposal before any costly mistakes are made.
Prior Approval vs Planning Permission
Many people confuse prior approval with planning permission, but they are different.
Planning permission assesses your proposal in its entirety, while prior approval only considers specific planning matters set out in legislation.
Determining which route applies isn’t always straightforward. That’s why many homeowners and developers seek expert planning advice before investing time and money into a project.
Why Professional Advice Can Save You Time and Money

Common Mistakes That Delay Prior Approval Applications
Applications are often delayed because applicants:
- Assume their project doesn’t require prior approval.
- Submit incomplete drawings or documentation.
- Misinterpret permitted development rules.
- Begin construction before approval has been granted.
- Overlook local planning restrictions such as Article 4 Directions or conservation areas.
Avoiding these mistakes early can save significant time, money, and unnecessary stress.
