Any new electrical wiring or electrical components for domestic premises or a small commercial premise linked to domestic accommodation, will be required to be designed and installed in accordance with the Building Regulations.
As a homeowner, builder or designer you need to be aware of your responsibilities under the Building Regulations when new electrical wiring and components are installed.
Non Notifiable Work
If the work is very minor in nature all you have to do is ensure that any electrical work is installed in accordance with manufacturers instructions, and is done in such a way that it is safe. If you are in any way unsure about how to install new wiring, electrical sockets etc, then get a qualified electrician.
You DO NOT need to tell Building Control about repairs, replacements and maintenance work; or extra power points or lighting points, or other alterations to existing circuits (except in a kitchen, bathroom, or outdoors).
If you are not sure about this, or you have any questions, contact the Building Control Department.
All work, whether you need to tell your local authority about it or not, must be done to the standards in the IEE ‘wiring regulations’.
