Permitted development rights uk: 2023

Section 1: Changes to Permitted Development Rights

In August 2020, significant changes were made to permitted development rights in the UK. These changes expanded the scope of what homeowners could do with their properties without the need for planning permission. However, it’s important to note that additional information has come to light since then, which may impact your home project. Here, we provide you with everything you need to know about permitted development in 2023. If you require specific advice for your home project, feel free to schedule a call with our team.

Section 2: Understanding Permitted Development Rights UK

Permitted development rights are a scheme established by the government that allows homeowners to extend or renovate their homes without a full planning application. Last year, this scheme was expanded to include larger projects and more options for home improvement. While there were also changes related to big developments like converting office blocks into flats, we will focus on projects commonly undertaken by everyday homeowners in this article. If you are a developer seeking tailored advice, please consult our team.

Section 3: Exclusions from Permitted Development Rights

Certain types of homes were excluded from the changes made last year. These exclusions apply to homes in Scotland, Wales, or Northern Ireland, listed buildings, flats or maisonettes, and some new developments. Homes built before 1948 were not affected by the changes, but it’s important to note that existing permitted development rights still apply. Conservation areas have some restrictions, but permitted development rights still apply. If you are unsure whether permitted development rights apply to your property, we offer free consultations to clarify your situation.

Section 4: Considerations and Recommendations

While permitted development offers an attractive option for many home projects, it may not always be the best choice for every situation. Local planning authorities are still adjusting to the new rules and regulations, which can be complex and demanding. Therefore, to ensure you make the right decision and receive proper support throughout your planning journey, we recommend contacting our in-house planning specialists for personalized advice. We want to help you make informed choices and provide the best assistance for your project.

Section 6: Risks and Project Protection

It’s important to be aware of potential risks and take measures to protect your project. Some key considerations include:

1. UK Building Regulations: All UK homes must comply with building regulations, covering various aspects such as structure, thermal performance, sound-proofing, drainage, and fire safety. It is recommended to commission technical drawings prepared by professionals like architects and structural engineers to ensure compliance.

2. Lawful Development Certificate: Obtaining a lawful development certificate provides documentation that proves your project was legal at the time of construction. It can also be useful when selling the property to demonstrate the legality of improvements.

3. Professional Support: Regardless of the chosen planning route, it is advisable to involve experienced professionals from the beginning. They can assist with surveying, design, planning, building regulations, party wall matters, and connecting you with trusted contractors and specialists.
