Coronavirus (Covid-19) latest information and advice More… × Procedures Procedures Extensions to residential properties do not always require planning permission, dependant upon their size and situation. The Town and Country Planning Act 1990 and the Town and Country Planning (General Permitted Development) Order 1995 dictate whether a proposal is permitted without the need for planning permission. Furthermore, some such permitted development rights have been removed in respect of particular dwellings. The legislation is also subject to revision from time to time. Prospective applicants are therefore advised to contact the Planning Section in order to seek advice upon the controls applicable. Telephone: 01639 686868 email: email@example.com Prospective applicants should note that although general guidance may be given with regard to the need for planning permission, a formal determination in respect of any specific proposal may only be obtained through an application for a Certificate of Lawful Development. This is a legally binding document which may prove useful when either selling a property or attempting to obtain a mortgage or loan for an extension. In addition to the above, most building work, other than straightforward repairs, will require Building Regulations approval for which a separate application must be made. additional controls may also be applicable for properties in Conservation Areas and for Listed Buildings. It should be noted that different types of applications will be determined by reference to different criteria. Approval under Building Regulations should not therefore be taken as an indication that planning consent has been or will be granted.
