Understanding Skylight Planning Permission: What You Need To Know

  • by

If you’re considering adding a skylight to your home, you may be wondering whether or not you need planning permission. Skylights can be a great way to bring more natural light into a space and can even add value to your property. However, it’s important to understand the regulations and requirements surrounding skylight installation before moving forward. In this article, we’ll take a closer look at skylight planning permission and what you need to know.

In most cases, adding a skylight to your home will not require planning permission. This is because skylights are considered “permitted development” under UK law. Permitted development rights allow certain types of building work to be carried out without the need for planning permission, as long as it meets certain criteria. Skylights typically fall under this category as long as they meet the following conditions:

1. The skylight does not protrude more than 150mm from the roof slope when installed flush with the existing roof.
2. The skylight is not higher than the highest part of the roof.
3. The skylight does not extend beyond the plane of the roof slope on the principal or side elevation that faces a highway.
4. The skylight is obscure-glazed and any opening should be 1.7m above the floor level.
5. If the property is located in a designated area such as a conservation area or national park, additional restrictions may apply.

It’s important to note that if your skylight does not meet these criteria, you may need to apply for planning permission before proceeding with the installation. This is especially true if your property is listed or located in a sensitive area where any changes to the external appearance of the building are subject to stricter regulations.

When in doubt, it’s always best to check with your local planning authority to ensure that your skylight project complies with the necessary regulations. They will be able to provide you with specific guidance based on the location and characteristics of your property.

In addition to planning permission, you may also need to consider building regulations when installing a skylight. Building regulations are separate from planning permission and are in place to ensure that any building work meets certain safety and energy efficiency standards. Skylights are considered a structural alteration to a building, so it’s likely that you will need to comply with building regulations when adding a skylight to your home.

Building regulations for skylights typically cover areas such as thermal performance, ventilation, fire safety, and structural stability. It’s important to work with a reputable installer who can ensure that your skylight project meets all necessary building regulations. Failure to comply with building regulations can result in fines and even having to remove or modify the skylight.

In summary, while most skylight installations do not require planning permission, it’s essential to understand the regulations and requirements that may apply to your specific project. By following the criteria outlined for permitted development and ensuring compliance with building regulations, you can enjoy the benefits of a well-lit and stylish home without running into any legal issues.

Remember, when in doubt, always consult with your local planning authority or a professional installer to ensure that your skylight project is completed in accordance with the law. With the right knowledge and guidance, you can successfully add a skylight to your home and enhance its beauty and functionality.
