All electrical installations deteriorate with age and use. They should therefore be inspected and tested at regular intervals to check whether they are in a satisfactory condition for continued use. Such safety checks are commonly referred to as 'periodic inspection and testing'.
Once completed you will be issued with an Electrical Condition Report (EICR).
A periodic inspection will:
- Reveal if any of your electrical circuits or equipment are overloaded.
- Find any potential electric shock risks and fire hazards.
- Identify any defective electrical work.
- Highlight any lack of earthing or bonding.
A schedule of circuits is also provided, which is invaluable for a property.How often is a periodic inspection required?
Your electrical installation should be inspected and tested as a minimum every:
- 10 years for an owner-occupied home.
- 5 years for a rented home.
Other times when a periodic inspection should be carried out are:
- When a property is being prepared for letting.
- Before selling a property or buying a previously-occupied property.
The inspection takes into account all the relevant circumstances and checks on:
- The adequacy of earthing and bonding.
- The suitability of the switchgear and controlgear. For example, an old fusebox with a wooden back.
- The serviceability of switches, sockets and lighting fittings. Items that may need replacing include: older round-pin sockets, round light switches, cables with fabric coating hanging from ceiling roses to light fittings.
- The type of wiring system and its condition. For example, cables coated in black rubber were phased out in the 1960s. Likewise cables coated in lead or fabric are even older and may well need replacing (modern cables use longer-lasting pvc insulation).
- Sockets that may be used to supply portable electrical equipment for use outdoors, making sure they are protected by a suitable residual current device (RCD).
- The presence of adequate identification and notices.
- The extent of any wear and tear, damage or other deterioration.
- Any changes in the use of the premises that have led to, or may lead to, unsafe conditions.
The competent person will then issue an Electrical Installation Condition Report detailing any observed damage, deterioration, defects, dangerous conditions and any non-compliances with the present-day safety standard that might give rise to danger.
If anything dangerous or potentially dangerous is found, the overall condition of the electrical installation will be declared to be 'unsatisfactory', meaning that remedial action is required without delay to remove the risks to those in the premises.
