Electrical Installation Condition Reports / Periodic Inspections

Licensing authorities, public bodies, insurance lenders and others including estate agents may require periodic inspection and testing of installations. Some reasons for these inspections and tests are:

  • To assess compliance with current wiring regulation BS7671 18th edition
  • To assess that the installation is not damaged or deteriorated so as to impair safety
  • On a change of occupancy (tenancy) of the premises
  • On a change of use of the premises
  • After alterations or additions to the original installation
  • Because of any significant change in electrical loading of the installation
  • Where there is reason to believe there is damage to the installation
  • To provide an important record of the installation at the time of the inspection, and make a recommendation for when the property needs re-testing in the future

Electrical Installation Certificates

The electrical installation certificate is used only for the initial certification of a new installation. The certificate provides a formal assurance that the installation complies with the requirements of the national standard for electrical safety and should be issued before the new installation is put into service. Some basic examples where this certificate would be used are:

  • Following a re-wire
  • Following an upgrade of the mains unit
  • Following the installation of a new circuit (i.e. smoke alarms)


This certificate recommends when the installation is to be tested again and a full periodic inspection and test should then be performed at this date. When the domestic electrical installation certificate expires it should be passed on to the electrical contractor doing the periodic inspection as a point of reference. This will not only save time for the inspector but money for the client ordering the work.

Minor Electrical Installation Works Certificate

Minor works certificates are only issued when there is an alteration or an addition to an existing circuit and does not include the wiring of a new circuit. A few examples that fall within its scope are:

  • Adding a socket to an existing socket circuit
  • Carrying work out on an existing lighting circuit, including altering any existing switching arrangements and /or an additional lighting point.

Frequently Asked Questions

What do you mean by an electrical installation?

Any fixed appliances, wiring to sockets, lights, fittings, meters or other apparatus.

How often is a periodic inspection required?

Your electrics should be inspected every 10 years for an owner-occupied property, and every 5 years for a rented property. It is also recommended that an electrical inspection is carried out when a property is being prepared to let, or when you are selling or buying a previously-owned property.

How long will the inspection take?

This depends on a number of factors such as the size of your property. An average home would take approximately half a day (4-5 hours) to complete. This includes compiling the report on our system.

Will we be without power during the inspection?

Yes the power will be turned off for an hour or two during the inspection. Our electricians will advise you of the likely time when they arrive.

What happens when the next report is due?

The EICR is valid for 5-10 years, depending on the property type, and we will compare the original EICR document to the new report to see if there are any areas of deterioration.

What happens if a potential danger is identified?

We will make you immediately aware of any potential dangerous at the time of discovery. An agreement will be made with you as to the appropriate action to be taken to remove the source of danger eg. by switching off and isolating the affected part of the installation until remedied.

What are my responsibilities as a landlord?

It is your responsibility to ensure electrical safety of a rented property. The electrical installation of the property should be certified safe from when a tenant moves in.
