The Inspection and Test Service
Following a visual appraisal and verification of the entire electrical installation, the following test procedures are applied where appropriate, in order to ascertain the safety of electrical installation :
Continuity – to ascertain that the earthing is continuous throughout the circuit.
Bonding Conductors Continuity – to ensure bonding is in place and effective.
Ring Circuit Continuity – ascertains whether or not the ring is complete.
Insulation Resistance – to test whether there has been any breakdown in insulation to the installation.
Polarity – to check that the installation is correctly wired.
Earth Fault Loop Impedance – to ascertain the Zs of the installation.
Earth Electrode Resistance – applies to TT systems only, to test the earthing rods.
RCD testing – to check that Residual Current Device disconnects the supply in the event of a fault.
Functional testing of isolators and breakers – to ensure that they disconnect the supply.

Upon completion of the electrical testing, a detailed Periodic Inspection Report is supplied containing the following certification:
Guidance Notes for recipients.
Schedule of Inspection and Schedule of Test Results.
The engineer who carried out your testing will also talk through the results with you and explain if any remedial work is necessary in order to remedy an unsafe installation.
If the electrical installation has any faults, they will be listed under the section of observations and recommendations and will be given one of the following codes:
code one – requires urgent attention
code two – requires improvement
code three – requires further investigation
code four – does not comply with current BS7671 standards

Although we are pleased to carry out any remedial work required, you are free to choose to have the work completed by a qualified third party.
We are fully insured to the value of £5m. Copies of our insurance details are available to clients upon request.
Our electrical testing prices for business premises are extremely competitive and start at just £15 per circuit.
