Cost breakdown
Council fees
The householder planning application fee is set nationally and revised every year — the Planning Portal lists the current fees. A Certificate of Lawfulness costs roughly half the standard application fee. Pre-application advice fees vary by council. All of these are paid directly to the council and are non-refundable, even if the application is refused.
Professional fees
Someone needs to prepare the drawings, write the design and access statement, and manage the application. This can be a traditional architect, an architectural technologist, or a project-specific service like PlanBuild. We price the drawings and application management after a free project review.
