Fixed Installation Testing

All Fixed Installation testing is carried out in accordance with Institute of Electrical Engineers 17th Edition, Wiring Regulations (BS7671) Guidance Note 3. All our Fixed Installation Test engineers are NAPIT accredited.

What Is Fixed Installation Testing?

This is also referred to as "Hard Wire Testing" or as a "Periodic Inspection" Essentially it is the testing of the electrical systems and services that conduct electricity around the building hence the term "Hard Wire Testing"

How Often Should This Testing Be Done?

For most commercial and educational establishments the recommended time frame between tests is 5 years. There are exceptions to this for example places of public entertainment and licensed premises as well as industrial premises. Please contact us if you are unsure of the frequency of inspection for your installation.

Do I have To Have My Installation Tested?

Generally the answer to this is yes. Not only is it a recommendation under the 16th Edition Wiring regulations, it is also a recommendation from the Health & Safety Executive and more commonly Insurance Companies are requesting this is carried out. It could affect your Insurance cover and may increase premiums if testing is not carried out.

Method Statement/Test Procedure

The Sure Test Electrical engineer will report to the client representative on arrival.

The electrical installation shall be tested and inspected (subject to certain limitations) in accordance with the following regulations and publications:

The Periodic Inspection and Report (PIR) and its associated schedules of circuits and test results will be produced using NAPIT endorsed computer software. The document will be accompanied by a detailed summary report, which will contain a comprehensive list of observations and recommendations for remedial works along with budget costs and photographic evidence where deemed necessary by the inspecting engineer

Insulation resistance testing may be limited between phase and neutral at distribution boards to minimise any possible adverse affect to sensitive equipment known or otherwise.

Light fittings (including external fittings), accessories (including FCU’s & fixed equipment) above a height of 3.5 metres to be visually inspected only. Earth loop impedance values for these circuits will be obtained from the nearest practical and relevant source.

Separate earth loop values will not be measured for alternative/back up sources such as generator supplies and UPS supplies.

Boiler Room/Plant Room equipment will not be tested other than for earth continuity although it will be visually inspected as far as it practical.

All test and inspection engineers are fully qualified and experienced; copies of relevant qualifications are available on request. All test equipment used is fully calibrated and again these certificates can be produced on request.
