We receive lots of questions from customers regarding planning permission for garden gazebos and pergolas. As we understand it via planning portal information you may not need planning permission to install a garden gazebo or pergola, but it depends on the gazebo's size, location, and use.
As a manufacturer and supplier of garden structures we are not a planning consultancy and we do recommend contacting your local authority for any official guidance. A link to planning portal content regarding garden buildings is shared below.
