Much of the attractive environment of the District results from the careful planning and control over buildings and their settings. This control, which is in addition to planning permission, covers fairly detailed changes including alterations to houses, erection of garden sheds and fences and removal of hedges, etc. Proposals, which could be detrimental to amenity or values in your neighbourhood are subject to control by the Council.

Use this form;
IF * Your property is, or was originally, leased from or was bought from the Council or the Development Corporation Commission for the New Towns.

OR* You live in a freehold property in Welwyn Garden City, then it is likely that covenants on your deeds require that you must get the Council’s consent for changes and if it lies within the Welwyn Garden City Estate Management Scheme area

If your property lies outside the Estate Management Scheme area you may still require consent under Conveyance or Leasehold conditions. These applications are dealt with by the councils Estates Department and for further guidance please contact them on 01707 357000. If you are in any doubt, check your deeds, the area of the Scheme (online at www.welhat.gov.uk) or contact the Planning Department, who will be happy to help.

Please note that, unlike planning permission, only the owner or lessee can submit the application rather than a prospective purchaser or neighbour.

*It is the Council’s policy to notify neighbours of proposals which may affect them. As part of this we publish the application on the councils website. Please let us know if you need any clarification.
