About this service
Electrical inspection and testing is used to verify new work, investigate an existing circuit, check protective measures or establish the condition of an installation. The correct test sequence depends on whether the work is being commissioned, altered, repaired or periodically assessed.
Instrument readings are only useful when interpreted against the circuit design and site conditions. Testing should be accompanied by visual inspection, circuit identification and a clear record of the scope.
Common problems we help with
New circuit needs verification
Continuity, insulation, polarity, fault protection and RCD performance must be established before energising.
Alteration has exposed wider concerns
A small addition can reveal inadequate earthing, damaged equipment or an unsuitable protective device.
Protective device trips unexpectedly
Testing helps distinguish load, leakage, short-circuit and equipment issues.
No reliable circuit information
Identification and testing may be needed before safe isolation or planned work.
How we carry out the work
Define what is being verified
The purpose, circuit boundaries and any acceptable limitations are agreed first.
Inspect and perform the correct tests
Dead and live testing is completed in a safe sequence using suitable calibrated instruments.
Record and explain results
Readings, observations and any further action are documented in the appropriate form.
What is normally included?
- Initial discussion about the property, symptoms, priorities and timescale
- Assessment of the relevant circuit, equipment, access and existing protection
- A written scope for the proposed electrical inspection & testing work
- The agreed installation or repair work, with disruption kept to a reasonable minimum
- Inspection, electrical testing and appropriate handover documentation
Before the work starts
- The purpose of the inspection and the person who will rely on the report
- The number, accessibility and labelling of circuits
- Previous certificates, alterations and known defects
- Whether operational areas need phased testing or out-of-hours access
What affects the price?
The price depends on the existing installation and the amount of work required. For electrical inspection & testing, the main factors normally include:
- Circuit count and distribution-board quantity
- Access to accessories, plant and tenanted rooms
- Quality of existing circuit schedules and records
- Extent of follow-up investigation or separately authorised remedial work
Testing, certificates and handover
Once the installation work is complete, we inspect and test it and provide the records that apply to the job.
- An identified inspection or test record
- Recorded results and observations for the agreed inspection
- An explanation of priorities and recommended actions
- A separate quotation where remedial work is requested
Electrical Inspection & Testing questions
Is testing the same as an EICR?
An EICR is one formal use of inspection and testing. New work, minor work and fault finding use different records and scopes.
Can a visual check prove a circuit is safe?
No. Visual inspection is important but cannot establish all electrical characteristics.
Will testing damage electronic equipment?
Circuits and connected equipment are managed before tests that could affect them. Access and correct isolation are essential.
Booking the work
What happens after you contact us
1. Discuss the job
Tell us about the property, the symptoms or the result you want. Photographs and model numbers are often helpful.
2. Inspect and quote
We check the relevant installation and give you a written quotation showing what is included.
3. Complete and test
We carry out the agreed work, verify it electrically and explain any controls, labels or certificates at handover.
