Inspection and Testing

Inspection and Testing

All electrical installations deteriorate with age and use, they should therefore be inspected and tested at regular intervals to check that they are in satisfactory condition for continued use.  Such safety checks are commonly known as ‘Periodic Inspection and Testing’, when completed you will be issued with an Electrical Installation Condition Report (EICR). 


Faulty and old wiring is one of the main causes or electrical fires in domestic and commercial premises. You can reduce the risk of a fire by checking the condition of your cables, switches, sockets and other accessories regularly. You cannot see electricity. Cables are usually hidden inside walls, consumer units are often hidden in cupboards, so it is not surprising that property owners and landlords often forget to check the condition of electrical installations for damage or wear and tear.

How often is a periodic inspection required?


You should have your electrics inspected and tested every:

  • 10 years for an owner-occupied home

  • 5 years for a rented home / change of occupancy

  • 5 years for commercial premises

  • 3 years for emergency lighting

  • 1 year for fire alarm systems

Who should carry out the periodic inspection and what happens?


Periodic inspection and testing should only be carried out by electrically competent persons, such as registered electricians. All of our electricians are qualified and registered with NICEIC to check the condition of your electrical systems against the UK standard for the safety of electrical installations, BS 7671 – Requirements for Electrical Installations (IET Wiring Regulations).

The inspection takes into account all the relevant circumstances and checks on:


  • The adequacy of earthing and bonding.

  • The suitability of the switchgear and control-gear.  For example, an old fusebox with a wooden back, cast-iron switches, or a mixture of both will need replacing.

  • 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, black switches and sockets mounted in skirting boards.

  • 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 current 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.
