Class A
The enlargement, improvement
or other alteration of a dwelling
house.
Planning Permission
Garage Conversion
Planning permission is not usually required, providing the work is internal and does not involve enlarging the building. Sometimes permitted development rights have been removed from some properties with regard to garage conversions and therefore you should contact your local planning authority before proceeding, particularly if you live on a new housing development or in a conservation area.
Where work is proposed to a listed building, listed building consent may be required.
Building Regulations
The conversion of a attached or integral garage, or part of a garage, into habitable space will normally require approval under the Building Regulations.
Summary
A Garage Conversion may not require planning permission but will probably require building control approval.

circumstances.
