- Reveal if any of your electrical circuits or equipment are overloaded.
- Find any potential electric shock risks or fire hazards.
- Identify any defective electrical work.
- Highlight any lack of earthing or bonding.
Why is a periodic inspection needed? Electrics deteriorate with use and age - and electricity can be deadly. So it’s vital that people aren’t put at risk.
How often is a periodic inspection required? Your electrics should be tested every:
- 10 years for a home.
- 5 years for a business.
- 3 years for caravans.
- 1 year for swimming pools.
- When a property is being prepared to be let.
- Before selling a property or when buying a previously occupied property.
The inspection takes into account all the relevant circumstances and includes the following
- The adequacy of earthing and bonding.
- The suitability of the switch 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 light fittings. All of these may need replacing: 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 safer pvc insulation).
- That residual current devices are used for sockets that may be used with outdoor electrical equipment.
- The presence of adequate identification and notices.
- The extent of any wear and tear, damage or other deterioration.
- The changes in use of the premises which have led to, or may lead to, problematic wiring.
