Electrical Testing & Inspection

What is a Periodic Inspection?

A Periodic Inspection is an inspection on the current condition of an electrical system. It could be termed an Electrical Safety Inspection. It is carried out to identify any faults or non-compliance of the system using the national safety standard for electrical installations as its measure.

  • The periodic inspection will:
  • ascertain if any of your electrical equipment or circuits are overloaded
  • find any potential electrical shock risks and fire risks in the electrical installation
  • identify any defective electrical work that has been carried out
  • highlight any lack of earthing or bonding in the system

A full set of tests is also carried out on the wiring in the installation and fixed electrical accessories. The customer also receives a schedule of circuits with relevant test results, which is invaluable for a property.

Why would I need a PIR?

There are many reasons why you may need a PIR, some examples are
  • Your moving into a new property and wanting to know the electrics are safe
  • You have a fault in your electrics and need to know what's wrong
  • Your preparing your property for rental
  • In the process of selling your home you’ve been asked for an electrical certificate
  • You are required to have one of your insurance policy
  • Your unsure of the current state of the electrical installation and want peace of mind


It is recommended that periodic inspection and testing is carried out at least every:

10 years for a domestic residential installation

5 years for a rented domestic residential installation

5 years for a commercial installation

3 years for caravans

1 year for swimming pools



All our engineers are fully qualified to facilitate all testing needs including portable appliance testing and electrical inspection and testing of private and commercial buildings.

Fixed Installation Testing

This is the testing of the circuits contained within the fabric of a building - the socket outlets, lighting circuits and various other circuits. How often this testing should be undertaken depends very much on the environment and use of the installation; some areas should be tested annually and others perhaps every five years. Our in-house experts can advise further.

Portable Appliance Testing

A portable appliance is any piece of equipment that can be moved from area to area and reconnected to the supply via a plug and socket system. During everyday use such appliances become worn or damaged which can lead to them becoming unsafe if not properly maintained. PAT Testing is a documented method of electrical maintenance.

The reasons to undertake PAT Testing include complying with the Electricity at Work Regulations - to minimise the risk of fire and injury caused by electrical appliances, to remove the risk of your insurance company disputing a claim for damage from fire through insufficient maintenance, and to comply with ISO Quality Assurance.
