Fixed Wire Testing and Inspection Services

Our services

What is an electrical installation condition report (EICR)?

Fixed wire testing, often called an Electrical Installation Condition Report (EICR), is a structured inspection and testing of your building’s permanent electrical installation. It confirms that distribution boards, circuits, protective devices and earthing are safe and suitable for continued service. The process follows BS 7671 requirements, supports your duties under the Electricity at Work Regulations 1989, and results in a clear report with observations and coded actions so you can plan remedials with confidence.

Why choose Complii?

How we can help.

Protect your people, property, and business. Here’s why we’re the right choice for fixed wire testing.

Legal compliance and insurer assurance

An up to date EICR helps demonstrate compliance with the Electricity at Work Regulations and current wiring regulations. It provides credible evidence for auditors, insurers and landlords that your installation has been checked by competent engineers.

Safer workplaces and reduced risk

Testing identifies deterioration, damage and incorrect modifications before they lead to shock, overheating or fire. Targeted remedials improve protection for people, plant and property.

Clear, prioritised outcomes

You receive a plain English report with observations graded C1, C2, C3 or FI. This makes it simple to see what needs immediate action, what is urgent, and what can be scheduled.

Minimal disruption to operations

Surveys are planned around your programme, including out of hours or phased working. Where isolation is required, we coordinate with your team to keep downtime short and controlled.

Better budgeting and lifecycle planning

Findings are grouped and prioritised, helping you bundle remedials efficiently, forecast replacements and avoid surprise costs.

A maintained compliance cycle

We track due dates and agree sensible re test intervals for each site. Reminders, record keeping and follow up support keep you on top of ongoing compliance.

Your questions answered.

The law requires electrical systems to be maintained so that danger is prevented. An EICR is the recognised way to evidence that your fixed installation has been inspected and tested by a competent person and that any risks are being managed.
Intervals depend on the type and use of the premises, the condition of the installation and any insurer requirements. Many commercial offices are tested every five years or at a change of occupancy, while higher risk or more demanding environments may need shorter intervals. We will agree a site specific frequency after the initial review.
- C1 danger present, immediate action required
- C2 potentially dangerous, urgent remedial work needed
- C3 improvement recommended, not immediately dangerous
- FI further investigation required to determine risk and action
Some tests require temporary isolation of circuits. We plan the sequence with you, carry out testing out of hours where helpful, and keep any shutdowns as short as possible. Critical systems are identified in advance so continuity plans are in place.
Typical tasks include visual inspection, verification of earthing and bonding, continuity and insulation resistance tests, polarity checks, earth fault loop impedance measurements, and testing of RCDs. Distribution boards are inspected and labelled, and results are recorded in schedules with clear observations.
Yes. We provide quotations for any remedials, complete the work to the relevant standards, and issue updated certification. Digital copies of the EICR, schedules and asset records are supplied for your compliance files.
