IEE and building regulations
This statement means that most electrical work must be certified for safety, for which you have two choices:
However, there are certain electrical jobs that are ‘non-notifiable’ which do not require a safety certificate and you can therefore DIY, if you feel you know how.
Non-notifiable electrics
Repairs, replacements and maintenance work to existing circuits.
Addition of lighting points, switches and sockets to existing circuits (except in kitchens, bathrooms and outdoors).
Notifiable electrics that must be certified
Addition of any new circuits.
Any work (except repairs or replacements) in a kitchen, bathroom or outdoors.
If in doubt, always seek professional help, or advice from your Local Authority.
