Do I need building control to refurbish an existing dormer roof with insulation
Significant changes to insulation and thermal elements would normally require building regulations approval. The extent to which this applies depends on the existing insulation and what it will be replaced with.
If the work is completed by a member of a competent persons scheme, then an application for approval will not be required.

Common Questions
Demolishing a building may require planning permission or prior approval, depending on factors such as the building’s type, size, and location.
Before starting any demolition work, it’s important to consult your local planning authority to confirm what permissions are needed. This helps avoid the risk of enforcement action or legal consequences.
You will also need to ensure you conform to the building regulations around the demolishing of a building.
You can usually put up new fences, gates or garden walls without planning permission, as long as you stay within permitted height limits. If the structure is adjacent to a highway (including footpaths), it must not exceed one metre in height. For all other boundaries, the maximum permitted height is two metres. Anything taller than these limits will require planning permission.

A council’s planning department, known as the local planning authority (LPA), is the local government body responsible for managing and overseeing the planning system in a specific area.
You can use the search tool on Planning Portal to find the contact details for any local planning authority in England and Wales.
If an outdoor kitchen is not a permanent structure, then planning permission will normally not be required.
Where planning permission is required, it may be granted through permitted development rights, provided it meets the limits set out in legislation. Most outdoor kitchens fall within the set limits unless they are particularly tall or close to a boundary.
While there is no specific permitted development right for ‘outdoor kitchens’ it may be classified as an ‘outbuilding’.

If the structure exceeds the limits set out through permitted development rights, then it will require an application for planning permission.
Different rules may apply if you live in a listed building or conservation area. If this is the case, you may wish to consult your local planning authority.
Read about the building regulations that cover outdoor kitchens.
If you carry out development without the necessary planning permission, and it doesn’t fall within permitted development rights, you may be in breach of the planning rules. In such cases, you will usually need to submit a retrospective planning application to seek approval for the work already completed or started. However, there is no guarantee that permission will be granted.
