Qualified electricians, full wiring safety reports








Our qualified electricians carry out full EICRs across Londonderry, from the Walled City and Cathedral Quarter to Crescent Link, Skeoge Link, and Ardmore Road. An Electrical Installation Condition Report checks the fixed wiring in your property against BS 7671 and records any defects that could affect safety. For private rented homes in England, it is a legal requirement, and many landlords in Londonderry book the same standard before a tenancy starts, after major electrical work, or when an old report is due for renewal. We test the installation properly, then set out the findings in plain English so you know exactly what needs attention.
Londonderry has a housing stock that ranges from pre-1919 terraces in the city centre to modern new builds at The Oaks, Clon Dara, Ardmore, and Ballyoan. Local housing data shows terraced homes at 35.1%, semi-detached homes at 33.8%, detached homes at 20.5%, and flats at 10.6%, so many properties contain wiring from different building eras. Older homes in the Walled City, Waterside, and the Cathedral Quarter can still hide legacy circuits, ageing consumer units, or mixed rewires completed over time. That makes a proper electrical safety inspection a practical step, not a box-ticking exercise.

An EICR is a full condition check, not a quick glance at the fuse box. Our electricians inspect the consumer unit, test the circuit breakers and RCDs, check sockets and light fittings, and assess the condition of the fixed wiring throughout the property. We also carry out insulation resistance, polarity, continuity, and external earth fault loop impedance testing. Those readings tell us whether the installation is still working safely or whether hidden faults are starting to show.
Older masonry homes around the Walled City and Waterside often show signs of past alterations, especially where kitchens, lofts, or extensions have been added. Damp from river flooding near the Foyle, surface water in low lying streets, or moisture in older cellars can affect accessories, junction boxes, and meter positions. In those cases, our report gives a clear route to repair rather than a vague warning. Landlords, insurers, and managing agents tend to want that level of detail before they sign off a property.

The 5-year cycle used for private rented homes in England is the standard many landlords follow in Londonderry, because it keeps compliance records current and gives a clear date for the next inspection. Where that framework applies, the landlord must give tenants a copy of the report within 28 days, and local authorities can issue penalties of up to £30,000 per breach. If the report shows C1 or C2 defects, remedial work should begin within 28 days and any further investigation should be completed without delay. Our qualified team provides the written report in a format that is easy to share with tenants, letting agents, and insurers.
Local housing data helps explain why the inspection schedule matters. Terraced homes account for 35.1% of the stock in Derry City and Strabane District Council, semi-detached homes for 33.8%, detached homes for 20.5%, and flats for 10.6%. Older terraces in the Walled City, Cathedral Quarter, and parts of Waterside often contain original wiring routes, mixed earthing arrangements, or consumer units that have been updated in stages. Properties built between 1945 and 1980 can also carry ageing sockets, outdated accessories, and circuits that no longer match the way the home is used.
homedata.co.uk records show 1,200 property sales in the last 12 months, with an overall average house price of £171,000 across the Londonderry and Derry City and Strabane District Council area. Detached homes sit at £231,000, semi-detached homes at £165,000, terraced homes at £120,000, and flats at £110,000. That spread matters because a rental market with a wide mix of property ages usually carries a wide mix of wiring conditions too. New build homes are part of the picture as well, but they do not remove the need for inspection once the property has been occupied, altered, or let for a period of time.
A clean report depends on how each defect is coded. C1 means danger present, so the electrician has found something that needs immediate action, such as exposed live parts or a severe shock risk. C2 means potentially dangerous, which covers faults that are not an immediate danger at the moment of inspection but could become dangerous, such as missing bonding or signs of overheating. FI means further investigation is needed because part of the installation could not be confirmed as safe.
C3 works differently. It means improvement recommended, not a failure, so the installation may still be satisfactory even though a better standard could be reached later. A report can still be satisfactory with C3 notes, but a C1, C2, or unresolved FI finding makes the overall outcome unsatisfactory. That distinction matters for landlords, because the final certificate outcome drives the next action. Our electricians write each observation clearly so you can see which issue is urgent and which can be planned for later.

Start with a quick booking and tell us the property type, number of bedrooms, and any known electrical issues. That helps our team plan the visit and allow enough time for the inspection.
We arrange a competent electrician who is registered with a relevant scheme and works to BS 7671. They arrive ready to inspect the installation methodically, not just the consumer unit.
Our electrician checks the condition of sockets, switches, light fittings, the consumer unit, bonding, and visible wiring routes. Signs of wear, damage, overheating, or poor workmanship are noted before testing begins.
We isolate power for part of the inspection so we can test insulation resistance, continuity, and polarity. This stage checks the hidden part of the installation that cannot be judged by appearance alone.
Power is restored so we can test RCD operation, earth fault loop impedance, and circuit performance under live conditions. The readings tell us whether the system should keep working safely under normal use.
After the visit, we issue the EICR with the observations, the overall result, and any follow-up actions. If remedial work is needed, we can quote for the repairs and arrange a retest once the defects are fixed.
An unsatisfactory EICR does not mean the whole property is unusable, but it does mean the installation has failed to meet the required standard in one or more areas. C1 and C2 codes point to real risk, and FI items mean the electrician could not confirm part of the installation properly. In rented homes, that should trigger action quickly, because a damaged accessory, overheated consumer unit, or missing bonding can create shock or fire risk. Our electricians can often identify which items need immediate isolation and which can wait for planned remedial work.
Where the English rental rules apply, landlords must begin remedial work within 28 days and keep evidence of the repairs. If the issue is serious, the local authority can ask for copies of the original report, the repair invoice, and the follow-up inspection. Penalties can reach £30,000 per breach, so keeping the paperwork organised matters as much as the repair itself. After the defects are fixed, we retest the affected circuits and record the installation as safe where the readings support that outcome.
In practice, the most common follow-up jobs are not dramatic. We may replace a damaged socket, improve earthing and bonding, correct a loose connection, or change a consumer unit that no longer meets current expectations. A property near the River Foyle that has damp ingress, for example, may need extra attention around ground floor accessories and external supplies. Once the faults are resolved, the paperwork should show a clear audit trail from defect to repair to retest.
Homeowners are not usually under the same legal pressure as landlords, but an EICR still gives a clear picture of the state of the wiring. We normally recommend one every 10 years for an owner-occupied home, or sooner for older properties, homes that have been altered, and places where there are signs of overheating, tripping, or damaged accessories. In the Walled City and Cathedral Quarter, a pre-1919 property may still contain older wiring routes that deserve a closer look, especially after refurbishment. A report is also useful before a sale, after a loft conversion, or when an insurer asks for electrical evidence.
Newer homes need attention as well. home.co.uk listings currently show active developments such as The Oaks off Crescent Link from £199,950, Clon Dara on Skeoge Link from £189,950, Ardmore Road from £195,000, and Ballyoan on Crescent Link from £229,950. Those homes are much newer than the terraces and masonry houses found in the city core, but wiring can still be altered after completion. If a home has been extended, had a new kitchen fitted, or picked up an EV charger or garden supply, a fresh inspection gives a proper safety record.
Property type and age both matter in Londonderry because the housing mix is so varied. Traditional brick, rendered, and stone homes often have slate or tile roofs, with service routes that have been changed several times over the years. Even in post-1980 housing, damp from flood-prone or low lying areas can affect external electrics, meter boxes, and outbuildings. A homeowner who knows the wiring is sound avoids surprises later, especially when selling or planning further work.

For private rented homes in England, yes, a valid EICR is required and must be renewed every 5 years, or sooner if the report recommends an earlier check. The landlord must also give a copy to the tenant within 28 days. Many landlords in Londonderry keep to the same timetable so the property record stays current and easy to evidence.
Our EICRs start from £120. The final price depends on property size, number of circuits, the age of the installation, and how easy it is to access the consumer unit and test points. A smaller terrace will usually take less time than a large detached house or a property that has had several alterations.
Most rental properties are inspected every 5 years, unless the report says a shorter interval is needed. Homeowners are usually advised to arrange one every 10 years, and older homes can benefit from a more frequent schedule. If the last report contained C1, C2, or FI items, the follow-up date may be much sooner.
The report will list the defects with their codes, so you can see exactly what failed and why. C1 and C2 items need remedial work, and in some cases the affected circuit should be made safe straight away. Once the repairs are completed, our team can retest the installation and issue the next step in writing.
Most inspections take 2-4 hours, depending on the size of the property and the number of circuits. A flat with a straightforward layout is usually quicker, while a large detached home, a converted house, or a property with outbuildings can take longer. If we need to isolate power for dead testing, the interruption is normally brief.
C1 means danger present and immediate action is needed. C2 means potentially dangerous and remedial work should not be delayed. C3 means improvement recommended, but the item does not make the report fail on its own.
We check the consumer unit, sockets, light fittings, earthing, bonding, fixed wiring, and the condition of the circuits across the property. Testing covers insulation resistance, continuity, polarity, and earth fault loop impedance. Our electricians also look for signs of overheating, damage, and poor workmanship that may have been hidden behind later alterations.
Someone usually needs to provide access unless keys have been arranged in advance. We may need to switch power off for part of the test, so it helps to be prepared for a short interruption to appliances and heating controls. Clear access to the consumer unit, loft space, and any outbuildings makes the visit run more smoothly.

Our EICRs start from £120, with the final price shaped by the size of the property, the number of circuits, and how much testing is needed. A compact terrace in the city centre with a straightforward consumer unit is usually quicker to inspect than a detached home in a newer development with more sockets, more external supplies, and more rooms to test. The age of the installation also matters, because older wiring often needs more checks and more written observations. If the property has a detached garage, loft conversion, or altered kitchen, that can add time too.
homedata.co.uk records show an overall average house price of £171,000 across the area, with detached homes at £231,000 and terraced homes at £120,000. The inspection fee does not follow the house price itself, but those figures do give a sense of the local housing spread and the different property types we see every week. A newer home off Crescent Link may take less remedial work than a pre-1919 property in the Walled City, yet both still need a proper report when the installation has not been checked for a while. That is why we quote on the actual circuit layout rather than on broad assumptions.
After the inspection, we issue the report soon after the readings and observations have been checked and written up. If the result is satisfactory, you receive the report and can file it with the tenancy records or keep it for your own notes. If the result is unsatisfactory, we can quote for the repairs separately, explain which items are urgent, and return to retest once the defects are fixed. That approach keeps the process clear from the first visit to the final sign-off.
