How Often Should Electrics Be Tested? A Portsmouth Electrician Explains
Electrical testing is something many homeowners overlook until a problem arises. Unlike boiler servicing or smoke alarm checks, there is no annual reminder prompting you to have your electrics inspected. Yet regular testing identifies potential hazards before they cause fires, electric shocks, or costly damage to your home.
As NICEIC registered electricians serving Portsmouth for years, we carry out electrical inspections on properties of all ages across the city. This guide explains how often you should test your electrics, what testing involves, legal requirements for landlords, and signs that your property may need inspection sooner rather than later.
Recommended Testing Intervals
The frequency of electrical testing depends on your property type and circumstances. Industry guidance from the Institution of Engineering and Technology recommends different intervals for different situations.
For owner-occupied homes, testing every ten years is the standard recommendation. This interval assumes normal use with no significant changes to your electrical installation. If your property is older, has known issues, or you have concerns about its condition, more frequent testing may be sensible.
For rental properties, landlords must have electrics tested at least every five years under current legislation. This is a legal requirement, not just a recommendation. We will cover landlord obligations in more detail below.
For properties with swimming pools, the recommended interval is one year due to the increased electrical hazards associated with water. Properties with older wiring, particularly those with rubber-insulated cables common in pre-1960s installations, should be tested more frequently, typically every five years regardless of ownership status.
What Is an EICR?
An Electrical Installation Condition Report, commonly known as an EICR, is the formal document produced following a periodic inspection of your property’s electrical installation. It replaces the older Periodic Inspection Report and provides a comprehensive assessment of your electrics’ safety and condition.
During an EICR inspection, a qualified electrician examines your consumer unit, wiring, sockets, switches, light fittings, and other electrical components. They carry out a series of tests including earth fault loop impedance, insulation resistance, polarity, and RCD operation. These tests identify faults that visual inspection alone cannot detect.
The report categorises any defects found using a coding system. Code C1 indicates danger present, requiring immediate remedial action. Code C2 indicates potentially dangerous conditions requiring urgent attention. Code C3 indicates improvement recommended but not immediately dangerous. Code FI means further investigation is required to determine the nature and extent of a suspected fault.
Based on the findings, the overall installation receives a satisfactory or unsatisfactory rating. An unsatisfactory rating does not necessarily mean your electrics are dangerous, but it does indicate that remedial work is required to bring the installation up to an acceptable standard.
Legal Requirements for Landlords
Since July 2020, landlords in England have been legally required to have electrical installations in their rental properties inspected and tested by a qualified person at least every five years. This applies to all new tenancies from July 2020 and all existing tenancies from April 2021.
Landlords must provide a copy of the EICR to existing tenants within 28 days of the inspection, to new tenants before they occupy the property, and to the local authority within seven days if requested. The report must be kept and provided to the person carrying out the next inspection.
If the EICR identifies remedial work as necessary, landlords must complete this work within 28 days or any shorter period specified in the report for urgent issues. Written confirmation from the electrician that the work has been completed must be provided to tenants and retained for records.
Failure to comply with these regulations can result in local authority enforcement action and fines of up to £30,000. For Portsmouth landlords with properties across Southsea, Fratton, and other rental hotspots, staying on top of EICR requirements is essential for legal compliance and tenant safety.
When to Test Sooner
While the standard intervals provide a baseline, certain situations warrant electrical testing regardless of when your last inspection took place.
When Buying a Property
If you are purchasing a property, particularly an older one, an EICR before completion gives you clear information about the electrical installation’s condition. Many Portsmouth properties, especially Victorian and Edwardian homes in Southsea and Old Portsmouth, have electrical installations that have been modified and extended over decades. An inspection reveals whether the installation is safe and what work may be needed, helping you budget accordingly or negotiate on price.
After Major Work
Following significant building work, particularly extensions, loft conversions, or kitchen renovations, testing verifies that new electrical work has been properly integrated with your existing installation. While new work should come with its own certification, an EICR confirms the overall installation remains safe and compliant.
When Problems Arise
If you experience frequent tripping, flickering lights, buzzing sounds from sockets or switches, burning smells, or discolouration around electrical fittings, do not wait for your next scheduled inspection. These symptoms can indicate serious faults that require immediate investigation. An EICR identifies the underlying cause and specifies what remedial work is necessary.
Older Installations
If your property has never had an electrical inspection to your knowledge, or you have no records of previous testing, arranging an EICR provides baseline information about your installation’s condition. This is particularly important for older Portsmouth properties that may have wiring dating back several decades. Rubber and lead-sheathed cables from pre-1960s installations deteriorate over time and can present serious hazards that only testing reveals.
Signs Your Electrics May Need Attention
Between formal inspections, certain warning signs indicate your electrical installation may have developing problems that warrant professional assessment.
Frequent tripping of circuit breakers or blowing of fuses suggests circuits are overloaded or faults are developing. While occasional tripping is normal, regular occurrences need investigation. Lights that flicker or dim, particularly when appliances switch on, can indicate loose connections, overloaded circuits, or problems with your supply.
Sockets or switches that feel warm to the touch, show signs of scorching or discolouration, or emit burning smells require immediate attention as these indicate potentially dangerous overheating. Buzzing, crackling, or sizzling sounds from electrical fittings suggest arcing, which can lead to fires if left unaddressed.
Electric shocks or tingles when touching appliances or switches indicate earthing faults that compromise your safety. Even minor shocks should not be ignored. If your consumer unit still has rewirable fuses rather than modern MCBs, or lacks RCD protection, upgrading provides significantly improved safety regardless of your wiring’s age.
What Happens During an Inspection
Understanding what an EICR involves helps you prepare for the inspection and know what to expect.
The electrician begins with a visual inspection of your consumer unit, checking its condition, labelling, and whether it meets current standards. They examine accessible wiring, sockets, switches, and light fittings for damage, wear, and compliance with regulations. They check that adequate earthing and bonding are in place throughout your installation.
Testing follows the visual inspection. This requires turning off power to individual circuits to carry out dead testing, then restoring power for live testing. The electrician tests every circuit for insulation resistance, earth fault loop impedance, and polarity. RCDs are tested to verify they trip within required timeframes. These tests identify faults that are invisible to visual inspection but could cause shocks or fires.
A typical domestic EICR takes between two and four hours depending on property size and installation complexity. Larger properties with more circuits take longer. The electrician needs access to your consumer unit and ideally all rooms to inspect sockets, switches, and fittings. Your electricity will be interrupted during testing, though typically only for short periods on individual circuits rather than the whole house at once.
EICR Costs in Portsmouth
The cost of an EICR depends on property size and the number of circuits in your installation. For a typical two to three bedroom Portsmouth property, expect to pay between £150 and £250 for a comprehensive inspection and report. Larger properties with more circuits cost more due to the additional testing time required.
This cost covers the inspection, all testing, and production of the formal EICR document. It does not include any remedial work that the inspection identifies as necessary. If faults are found, we provide a separate quotation for the required repairs so you can budget accordingly.
Compared to the potential cost of electrical fires, shock injuries, or local authority fines for non-compliant rental properties, regular testing represents excellent value for the peace of mind and protection it provides.
Choosing a Qualified Electrician
EICRs must be carried out by a qualified and competent person. For landlords meeting their legal obligations, this means using an electrician who is a member of a government-approved scheme such as NICEIC, NAPIT, or ELECSA. These schemes verify that members have appropriate qualifications, insurance, and are subject to regular assessment.
As NICEIC registered electricians, we are qualified to carry out EICRs that meet all legal requirements for landlords and provide homeowners with comprehensive, reliable assessments of their electrical installations. Our registrations are verified, and our work is subject to regular inspection to maintain standards.
