What is a Velux loft conversion?

A Velux loft conversion, also known as a rooflight loft conversion, is one of the simplest and most cost-effective types of loft conversion. In a Velux conversion, Velux windows (a popular brand of roof windows) are installed flush with the line of the roof to bring in natural light and ventilation, enhancing the usability of the space. 

This type of conversion doesn’t involve altering the existing shape or pitch of the roof, making it less disruptive compared to other types of loft conversions such as dormer or mansard conversions.


What is Permitted Development?

Permitted development rights are a set of guidelines that allow homeowners to make certain modifications to their property without needing to apply for planning permission. 

In the context of loft conversions, permitted development rights might allow the transformation of a loft space into a livable area without obtaining formal planning consent, provided the changes are within specific limits and conditions.

Certificate of lawfulness

A Certificate of Lawfulness is a legal document issued by the local planning authority that formally confirms that a development, such as a loft conversion, is lawful and complies with all relevant planning regulations, including permitted development rights.

Having a Certificate of Lawfulness for a loft conversion that is considered permitted development can be highly beneficial, especially when it comes to selling the property in the future. The certificate acts as official evidence that the loft conversion has been carried out lawfully and in accordance with all necessary planning permissions and regulations at the time of the work.

When selling a property, potential buyers and their solicitors often seek assurance regarding the legality of any alterations or extensions made to the property. Possessing a Certificate of Lawfulness can expedite the selling process by providing clear, legal confirmation that the loft conversion complies with all relevant regulations, adding credibility and assurance to the sale.
