Building Control, Water and Sewerage Consents
Early contact with building control, Northern Ireland Water, and other authorities is advised to secure necessary approvals for extensions and alterations before commencing work, including water supply, drainage, and septic tank requirements.
Whether planning permission is required or not you are advised to contact your local building control office at the earliest possible stage as many domestic extensions and alterations also require approval under the Building Regulations. Furthermore, you may wish to contact Northern Ireland Water Customer Services Unit at the design stage with regard to water supply requirements, foul water and surface water sewerage requirements, septic tank discharge and, in particular, to ascertain if an existing water main or sewer crosses the site. All appropriate consents should be obtained before you commence any work.
