A loft conversion can often be considered permitted development, not requiring an application for planning permission, provided they meet all the necessary criteria and there are no constraints that restrict or remove permitted development rights.
For loft conversions that are likely to fall within permitted development a lawful development certificate is recommended, so that you know your project is compliant and is protected from any retrospective planning issues, enforcements or penalties. Building regulations may also be required depending on the extent of the works.
As a guide any loft conversion that meet these criteria will not need planning permission:
Bear in mind that any previous roof space additions must be included within this volume allowance. Although you may not have created additional space a previous owner may have done so.
An extension beyond the plane of the existing roof slope of the principal elevation that fronts a highway is NOT permitted development.
If there are any constraints that limit or remove permitted development rights or even one of these criteria is not met, then you are required to submit an application for planning permission.
If planning permission is required but the works are completed without first securing the proper planning approval you may face retrospective planning issues. If the local planning authority determine that planning permission was required an enforcement and or penalties may be issued. If planning permission cannot be secured retrospectively the converted loft may need to be put back to its original state.
