Since 2005, all electrical work in dwellings in England and Wales whether carried out professionally or as DIY, must meet the requirements of Part P of the Building Regulations, and certain types of work is notifiable to a local building control. Using a competent electrician registered with one of the government approved schemes are able to self-certify their work.
Compliance with Part P is intended to keep you and your family as safe as possible from electrical hazards.
The requirements of Part P apply to new dwellings and to any alterations or additions to the electrical installations of existing dwellings, including full or partial rewires.
In England from April 2013 electrical work in a dwelling, or associated with its surroundings, is notifiable to a local building control body where the work includes:
- the installation of a new circuit, whether at low voltage (typically 230 V) or extra-low voltage); or
- the replacement of a consumer unit (fuse box); or
- any alteration or addition to an existing circuit in a special location*, whether at low voltage (typically 230 V) or extra-low voltage
*A special location is a room containing a bath or shower, swimming pool or a sauna heater.
An alteration or addition to an existing circuit in a room containing a bath or shower is notifiable only where carried out in the space surrounding a bath or shower.
An alteration or addition anywhere within a room containing a swimming pool or sauna heater is notifiable.
Part P states that anyone carrying out electrical work in a dwelling must ensure that reasonable provision has been made in the design and installation of the electrical installations in order to protect any persons who might use, maintain or alter the electrical installation of that dwelling from fire and injury, including electric shock.
Consultation with all interested parties is essential if satisfactory electrical design solutions are to be achieved. As well as conferring with any licensing or other authority exercising statutory control, it is advisable to consult with the Local Authority’s Fire Prevention Officer and the building insurer in respect of the proposed design for the electrical installation.
