Building Control Requirements for Telecommunications Infrastructure
Freestanding telecommunications masts and equipment are not subject to building regulations, but building control approval may be required where masts or equipment are attached to or placed on buildings (for example if roof structures need strengthening), or where equipment is housed in a building containing other accommodation.
Free standing telecommunications masts, cabling and equipment housings are not subject to building regulations. Where however masts or equipment are attached to or placed on a building, building control approval may be required to cover any alterations to the building (for example if the roof structure has to be strengthened, or access is provided). Where telecommunications equipment is housed in a building containing other accommodation, building control approval may also be required. In either case the building control department of the local district council should be consulted.
