Do you need planning permission for a rooflight loft conversion in Kirkintilloch?
Whether you need planning permission depends on your house and its location in Scotland.

A building warrant is needed for the conversion itself.
In Scotland a building warrant is needed before work starts on most extensions, loft conversions and conversions. It is issued by the council’s building standards service. When the work is finished, a completion certificate is submitted and accepted by the council after inspection.
