What an EICR Actually Is and Why the Paperwork Matters
An Electrical Installation Condition Report is a formal assessment of whether an existing electrical installation is in a satisfactory condition for continued use. It is not a certificate for new work and it is not a minor works form. The EICR records the results of inspection and testing, lists any departures from the current edition of BS 7671:2018 Amendment 2:2022 (the 18th Edition Wiring Regulations), and assigns an overall outcome of either Satisfactory or Unsatisfactory.
The legal weight of the EICR has grown considerably since the Electrical Safety Standards in the Private Rented Sector (England) Regulations 2020 came into force. Under Regulation 3, landlords must ensure that the electrical safety standards set out in the 18th Edition are met, and under Regulation 4 they must obtain an EICR from a qualified person at least every five years. Local authorities can impose financial penalties of up to £30,000 for non-compliance. As the electrician producing the report, your document is the evidence on which that compliance rests.
Beyond landlord work, an EICR produced for any consumer is subject to the Consumer Rights Act 2015. Section 49 requires that services are carried out with reasonable care and skill. If your report misses a genuine C1 or C2 and a subsequent fire or injury occurs, a failure to apply reasonable care and skill is the first thing a claimant's solicitor will point to. Good paperwork is your professional defence.
Step 1: What You Need Before You Start the Inspection
Before you arrive on site, gather everything that will allow you to inspect and test without unnecessary interruption. Request any existing installation documentation from the client: previous EICRs, minor works certificates, electrical installation certificates, and any as-fitted drawings. These tell you what the installation was designed to be, and any gap between that and what you find is itself a potential observation.
Confirm the scope in writing before you go. A standard domestic EICR covers the fixed wiring from the origin of the supply up to (but not including) appliances. If outbuildings, swimming pools, or solar PV systems are in scope, that needs to be agreed and documented separately, because the test schedule and the time required are different. Mismatched scope is one of the most common sources of disputes between electricians and landlords.
Check your test instruments are within calibration. BS 7671:2018 does not specify calibration intervals, but the IET Guidance Note 3 recommends annual calibration as a minimum for instruments used on inspection and testing. If your insulation resistance tester or loop impedance tester is out of calibration and a test result is later challenged, you have no defence. Bring a copy of your calibration certificates or at least note the calibration due dates on the report.
- •Previous EICR or electrical installation certificate for the property
- •Agreed written scope of inspection (including any exclusions)
- •Calibrated test instruments with valid calibration dates
- •Sufficient time allowed: typically 3 to 4 hours for a standard 2-bed domestic property
- •Schedule A and B forms, or the software equivalent, ready to complete on site
- •Torch, spare PPE, rubber-soled footwear, and a lockout kit
Step 2: Carry Out the Visual Inspection First
The visual inspection comes before any testing. Work through the installation systematically: consumer unit or distribution board first, then wiring accessories, then exposed wiring. You are checking for anything that is an immediate danger, anything that is potentially dangerous, or anything that does not meet the requirements of the current edition of BS 7671 and could deteriorate and become dangerous.
At the consumer unit, check for signs of overheating, correct protective device ratings against the cable sizes they protect, correct labelling of all circuits, the presence of RCD protection where required under BS 7671:2018, and whether the enclosure provides adequate protection against accidental contact. A split-load consumer unit with no RCD protection on the lighting circuits in a rented property is a C2 observation under current requirements. A live part accessible to touch due to a missing knockout blank is a C1.
Document every observation as you go, not at the end. Working from memory at the end of a three-hour inspection introduces errors. Each observation needs a location, a description of the departure from BS 7671, and a provisional code. You will confirm the codes when you write up the report, but noting them in real time keeps the report accurate.
- •Consumer unit: device ratings, labelling, RCD provision, enclosure integrity
- •Wiring accessories: signs of overheating, cracked faceplates, correct earthing
- •Exposed wiring: correct support, protection from mechanical damage, correct identification
- •Earthing and bonding: main earthing terminal, main bonding conductors to gas and water
- •Any special locations: bathrooms, kitchens, outdoor circuits
Step 3: Testing in the Correct Sequence
Testing follows a defined sequence for good reason. You always test protective conductor continuity before you carry out insulation resistance testing, because a broken protective conductor means the insulation resistance test could damage equipment or give misleading readings. The sequence set out in IET Guidance Note 3 is: continuity of protective conductors and bonding, insulation resistance, polarity, earth fault loop impedance, and finally functional testing including RCD operation.
Record every test result against the circuit it belongs to in the Schedule of Test Results (Part 2 of the EICR form). Do not leave blanks. If a test was not carried out, state why: for example, a circuit was not accessible because the tenant had furniture against the fuse box, or a circuit was isolated by the client before you arrived. Unexplained blanks look like missed tests to any reviewer, whether that is a local authority inspector or a solicitor.
For RCD testing, record the trip time at half rated tripping current, rated tripping current, and five times rated tripping current for Type S devices. BS 7671:2018 requires that RCDs rated at 30mA trip within 300ms at half rated current and within 40ms at rated current. If an RCD fails these tests, it is a C2 observation at minimum, and potentially a C1 if it is the sole protective measure for a circuit in a high-risk area such as a bathroom.
- •Continuity of protective conductors: use the wandering lead method for ring final circuits
- •Insulation resistance: minimum 1 MOhm at 500V DC between live conductors and earth
- •Polarity: confirmed at origin, at each distribution board, and at a sample of accessories
- •Earth fault loop impedance: compare measured Zs values against maximum values in Appendix 3 of BS 7671
- •RCD operation: trip times recorded at 50%, 100%, and (for Type S) 500% of rated current
- •Functional tests: switches, isolators, RCBOs operate correctly
Step 4: Applying Observation Codes Correctly
The observation coding system is where most EICR errors occur, and where the professional and legal consequences are most serious. There are four codes. C1 means danger present: risk of injury. C2 means potentially dangerous: urgent remedial action required. C3 means improvement recommended: the installation does not meet the current edition of BS 7671 but is not immediately dangerous and the departure is not categorised as C2. FI means further investigation required without delay.
C1 must be made safe before you leave site. This is not a commercial judgement, it is a professional and legal obligation. If you issue an EICR with a C1 observation and leave the installation in a dangerous state, you have breached your duty of care under the Health and Safety at Work etc. Act 1974 as it applies to persons who are not your employees. You have also potentially breached your obligations under the Consumer Rights Act 2015 s.49. If the client refuses to allow you to make the installation safe, you must record this refusal on the report and advise the client in writing of the danger.
C3 observations are frequently misunderstood. A C3 does not make the overall report Unsatisfactory. An installation can have multiple C3 observations and still receive a Satisfactory outcome. Only C1, C2, or FI observations result in an Unsatisfactory outcome. Overcoding observations as C2 when they should be C3 inflates remedial costs for the client and can expose you to a complaint under the Consumer Rights Act 2015 s.49 if the exaggeration is demonstrably unreasonable.
- •C1: Danger present, make safe before leaving site
- •C2: Potentially dangerous, client must instruct remedial works before re-letting in rental properties
- •C3: Improvement recommended, does not make the report Unsatisfactory
- •FI: Further investigation needed, results in Unsatisfactory outcome until resolved
- •Never apply a code without referencing the specific clause of BS 7671 that is departed from
Step 5: Completing the Schedule of Inspections (Part 1)
Part 1 of the EICR is the Schedule of Inspections. It is a checklist of items that were inspected visually, with a column for the result: a tick for satisfactory, a cross for unsatisfactory (with an observation number cross-referenced), N/A for not applicable, and LIM for a limitation on inspection.
Every LIM entry must have a corresponding explanation in the limitations section of the front page. Common legitimate limitations include inaccessible wiring concealed in a floor void with no access trap, circuits feeding equipment that could not be de-energised during the inspection period, or areas obscured by fixed furniture that the client did not move. Do not use LIM as a way to avoid inspecting things you could have inspected with reasonable effort. A limitation must be a genuine constraint, not a shortcut.
The Schedule of Inspections covers items grouped by section: external conditions, consumer unit, protective measures, isolation, earthing and bonding arrangements, cables, accessories and equipment, special locations, and prosumer equipment such as solar PV. Work through each group methodically. Skipping sections and then marking them as N/A when they were applicable is a common error that can make a report look incomplete or dishonest if it is later reviewed.
Step 6: Completing the Schedule of Test Results (Part 2)
Part 2 records the measured test results for every circuit. For each circuit you need: circuit description, protective device type and rating, cable reference method, number and cross-sectional area of conductors, the continuity test result for the protective conductor, the insulation resistance values, the polarity result, the measured earth fault loop impedance (Zs), and where applicable the RCD rated current and trip times.
It is acceptable to record measured Zs values rather than calculated values, as long as you note the ambient temperature at the time of testing if it differs significantly from the 20 degrees Celsius assumed in Appendix 3 of BS 7671. Hot or cold conditions will affect loop impedance readings, and a Zs value that appears to exceed the maximum at 20 degrees may be within limits when temperature-corrected. Show your workings.
Where a circuit has an observation, the observation reference number must appear in the relevant row of the test results schedule so that the reader can cross-reference from the test result to the observation description and code in Part 3. This linkage is what makes the report auditable. An observation that appears in Part 3 but has no corresponding entry in Part 2 raises questions about whether it was actually observed during testing or added later.
Step 7: Writing the Observations Section (Part 3)
Each observation must be written clearly enough that a different competent electrician can find the defect without asking you for clarification. Include the location, the specific nature of the departure, and the clause of BS 7671:2018 Amendment 2:2022 that it departs from. For example: 'Kitchen ring final circuit, socket outlet at worktop level adjacent to sink. Socket outlet installed within 30cm of sink, no additional protection against water ingress. Departure from BS 7671:2018 Regulation 701.512.3. Code: C2.'
Number your observations sequentially. If you have 12 observations, they are numbered 1 through 12. Each gets its own row. Do not group multiple separate defects into a single observation just to keep the list short: that obscures the scope of remedial work needed and makes it harder for the client or their contractor to price and carry out the work correctly.
Where you have applied an FI code, be specific about what further investigation is needed. 'Further investigation required into the earthing arrangements for the outbuilding circuit' is useful. 'Further investigation required' on its own is not. The Electrical Safety Standards in the Private Rented Sector (England) Regulations 2020 require that landlords carry out remedial work, and a vague FI observation makes it difficult to define what that work actually is.
Step 8: The Declaration, Signatures, and Next Inspection Date
The declaration section requires the signature of the person who carried out the inspection and testing, together with their name, qualifications, registration or scheme membership number, and the date of the inspection. If you are a member of a competent person scheme such as NICEIC or NAPIT, include your membership number. This is what gives the document its professional standing.
The next inspection date must be recommended on the report. For most domestic rented properties, the Electrical Safety Standards in the Private Rented Sector (England) Regulations 2020 cap the interval at five years. For some installations, the recommended interval under BS 7671 is shorter: commercial kitchens are typically recommended at one year, swimming pools at one year, and caravans at three years. Do not default to five years for every property without considering the installation type and condition.
If the outcome is Unsatisfactory, the landlord under the 2020 Regulations must ensure that remedial work is carried out within 28 days of the inspection, or within any shorter period specified in the report for C1 or urgent C2 items. Once remedial work is done, you or another qualified person must carry out a re-inspection and issue a new report or a written confirmation that the installation is now satisfactory. Keep a copy of every report you issue for at least six years, consistent with the contract claim window under the Limitation Act 1980 s.5.
- •Sign the declaration with your full name and qualifications
- •Include your competent person scheme registration number
- •State the date of inspection and the recommended next inspection date
- •For rented properties, the next date must not exceed five years under the 2020 Regulations
- •Provide the client with the original; retain a copy for at least six years
Worked Example: A 1-Bed Rented Flat in Manchester
The job is a periodic inspection on a 1-bed rented flat. The landlord has instructed you on 3 March 2025. The previous EICR was carried out on 1 March 2020, so the five-year requirement under the Electrical Safety Standards in the Private Rented Sector (England) Regulations 2020 has just expired. Your agreed fee is £180 including VAT, for a maximum of four hours on site.
On inspection, you find four observations. Observation 1: the consumer unit has a metal enclosure but no RCD protection on the lighting circuit. This is a departure from BS 7671:2018 Regulation 411.3.4 in the context of a rented dwelling. You code this C2. Observation 2: a socket outlet in the bathroom is installed within zone 2 as defined by BS 7671:2018 Section 701, which prohibits socket outlets in zones 0, 1, and 2 other than SELV shaver sockets. Code: C2. Observation 3: the main bonding conductor to the incoming water service is undersized at 4mm squared when the supply conductor is 16mm squared, requiring a minimum 6mm squared bonding conductor per BS 7671:2018 Regulation 544.1.1. Code: C2. Observation 4: a single socket outlet in the hallway has a cracked faceplate with no live parts exposed. Code: C3.
The overall outcome is Unsatisfactory because of the three C2 observations. The recommended remedial period for all three C2 items is 28 days. You note on the report that Observation 2 (the bathroom socket) should be treated as priority and addressed within 14 days given the risk context. The next inspection date recommended is 3 March 2030, conditional on remedial works being completed and confirmed in writing. Your invoice of £180 is issued on the same day as the report, with payment due within 14 days. If payment is not received by 17 March 2025, statutory interest at 8% above the Bank of England base rate begins to accrue under the Late Payment of Commercial Debts (Interest) Act 1998, along with a fixed compensation charge of £40 because the debt is below £1,000.
Common Pitfalls and How to Avoid Them
The most frequent error on EICRs submitted to landlords is overcoding C3 observations as C2 to generate more remedial work. This is commercially tempting but professionally dangerous. If a client complains to your competent person scheme and an independent reviewer downgrades your C2s to C3s, the scheme can remove your registration. The Consumer Rights Act 2015 s.49 also means the client could seek to recover any costs they incurred as a result of acting on an unreasonably coded report.
Equally dangerous is undercoding. Missing a genuine C1 and issuing a Satisfactory report when the installation has a live part accessible to touch is a serious error. If an injury subsequently occurs, you are exposed to a negligence claim. The six-year limitation window under the Limitation Act 1980 s.5 means a claim can arise years after you have moved on from the job. Keep your copies of every report.
A third common pitfall is failing to agree scope before starting. If the landlord assumes the EICR covers the outbuilding and you assume it does not, and the outbuilding then turns out to have a dangerous installation, the dispute will centre on what was agreed. A simple written scope confirmation sent by email before the job costs you nothing and is worth considerably more if things go wrong.
- •Do not code C3 observations as C2 to generate remedial work
- •Do not leave C1 items unsecured when you leave site
- •Do not use LIM codes to cover items you could have inspected
- •Agree scope in writing before arriving, especially where outbuildings or EV chargers are involved
- •Do not skip temperature correction of Zs values where conditions warrant it
- •Keep copies of every EICR for at least six years
