Information on Periodic Test & Inspections

All electrical installations deteriorate due to a number of factors, i.e. damage, wear and tear, corrosion,  excessive electrical loading, ageing and environmental influences. Legislation requires that electrical installations are maintained in a safe condition and therefore must be periodically inspected and tested.  Also, licensing authorities, public bodies, insurance companies, mortgage lenders and others may  require Periodic Inspection and Testing of electrical installations additionally, Periodic Inspection and Testing should be considered to assess compliance with BS 7671 (IEE Wiring Regulations), on a change of occupancy of the premises, on a change of use of the premises, after alterations or additions to the original installation, because of significant change in the electrical loading of the installation or where there is reason to believe that damage may have been caused to the installation.

About the Periodic Inspection

A series of well defined visual checks are carried out on the electrical installation followed by several different electrical measurements including continuity of circuit protective conductors, main and supplementary earth bonding, Continuity of ring final circuit conductors, Insulation resistance, Polarity, Earth-fault Loop Impedance, RCD tests including trip time in milliseconds, correct operation of switches and isolators, Prospective Fault Current.

In general the inspection should reveal:

1. Any aspects of the installation that may impair safety of persons or livestock against the effect of electric shock and burns

2. That there are no defects that could give rise to heat and fire and hence damage property

3. That the installation is not damaged or deteriorated so as to impair safety

4. That defects or non-compliance with the Regulations that may give rise to danger are identified.

Standard domestic Periodic Inspection Reports normally require up to 4 hours on-site. The client will be provided with test documentation and certification within 48 hours to allow the test data to be entered into our database.
