An EICR remedial quote should explain which finding each job addresses, why the work is needed and how completion will be verified. Before approving it, separate immediate safety action, urgent repairs, investigation and recommended improvements. Ask for the evidence behind expensive replacements and compare quotations covering the same work.
That approach helps a business owner make an informed decision without overlooking a genuine electrical danger. A high price alone does not prove overcharging, and a shorter repair list does not prove better advice.
This guide focuses on checking proposed work after an Electrical Installation Condition Report, or EICR. It is written for owners and managers of shops, offices and other business premises, with practical examples clearly identified as hypothetical.
Technical guidance checked on 27 September 2026. The Amendment 4 change to FI is explained below because the edition used for your report matters.
How to check an EICR remedial quote
Start with the complete report, including its observations, inspection schedule and test results. Put the quotation beside it and match each proposed job to an observation number and an identifiable location or circuit.
If the quotation says only “remedial works to achieve a satisfactory EICR”, request a breakdown. You need enough detail to understand what you are buying and whether the price includes verification after the repair.
The IET explains that observations should describe the actual problem, with remedial proposals set out separately. Its guidance also supports quoting observations individually so the customer can understand the work needed.
A useful review follows these questions:
- Which report observation does this job address?
- What defect, risk or uncertainty was identified?
- What does the proposed work achieve?
- Is a more limited repair technically suitable?
- What access, shutdown and follow up testing are included?
- What evidence will show that the observation has been dealt with?
One job may resolve several observations. Equally, one observation may need more than one task. Ask the contractor to show those connections rather than assuming the number of quotation lines must match the number of codes.
Deal with any immediate safety instructions first. Checking a price must never become a reason to keep using equipment that has been identified as dangerous.
What the codes mean for your spending decisions
The code helps explain priority, but the written observation tells you what the electrician actually found. Read both before deciding whether the proposed remedy makes sense.
The following summary uses the IET Amendment 4 model forms. C1 or C2 findings make the overall assessment unsatisfactory.
| Code | Meaning for the report | What to clarify in the quote |
|---|---|---|
| C1 | Danger is present. Immediate remedial action is necessary. | What has been made safe, what remains isolated and what permanent repair is proposed. |
| C2 | Potential danger requires urgent remedial action. | The defect, the proposed remedy and the urgency of the work. |
| C3 | An improvement is recommended. It does not itself make the result unsatisfactory. | The benefit of the improvement and its separately identifiable cost. |
| FI | Under Amendment 4, investigation is advised. FI itself does not make the result unsatisfactory. | The unresolved concern, the investigation scope and how findings will be reported. |
FI changed under Amendment 4
The IET July 2026 explanation of further investigation confirms that BS 7671:2018+A4:2026 treats FI as advisory. The wording changed from investigation being required without delay to investigation being advised.
FI still records an unresolved potential safety issue. Ask what needs establishing and what action is appropriate while that uncertainty remains. Advisory status is not evidence that the underlying concern is harmless.
For your quotation, separate the cost of establishing the facts from the cost of repairs that have not yet been identified. A defined investigation stage can be sensible where the final repair cannot responsibly be specified in advance.
Check the edition before challenging an older report
At the time of writing, two versions are current. The IET edition checker confirms that the previous version remains valid until 15 October 2026, alongside Amendment 4.
Check the BS 7671 reference and the report’s explanatory notes before alleging that its FI wording is wrong. The Amendment 4 change should not be used to retrospectively relabel an older report or dismiss outstanding concerns.
If the report and quotation appear to use different interpretations, ask the inspector to explain the basis in writing. Keep that clarification with the original documents.
Which guidance applies to commercial premises
Electrical Safety First’s Best Practice Guide 4, Issue 7.4 is expressly aimed at domestic and similar installations. It says its guidance may also apply to comparable situations in other types of installation.
That makes it a useful reference, but its examples cannot be transferred automatically to every warehouse, commercial kitchen or industrial workshop. The installation and circumstances still need assessment.
BS 7671 is the underlying installation standard. The IET’s Guidance Note 3, Inspection and Testing, tenth edition provides professional inspection guidance and has been updated for Amendment 4.
When a contractor cites a coding guide, ask how the example relates to your premises. Who uses the equipment, what it supplies and the conditions around it can matter to the assessment.
You do not need to become an inspector to ask that question. You need an explanation that connects the reference to the finding and then to the proposed work.
Claims in remedial quotations that deserve a closer explanation
Does older equipment need replacing
Age can justify closer examination and planning for replacement. It does not, by itself, establish a C2 defect.
Electrical Safety First’s Wiring Regulations Advisory Group answers 1.126 and 1.127 address older circuit breakers. They explain that there is no universal service life and that age or an older product standard alone does not require a code where the relevant checks reveal no dangerous deficiency.
Ask what has actually failed or deteriorated. Evidence of overheating, physical damage or unsuitable protection provides a different basis for a quote from a statement that the board looks dated.
There may still be a sound maintenance reason to replace serviceable equipment, such as difficulty obtaining suitable parts. Ask for that reason to be described clearly so you can distinguish a planned renewal from a repair to an identified defect.
Does missing RCD protection always mean the same code
An RCD is a protective device intended to disconnect the supply under particular earth leakage conditions. Whether protection is required, and how an existing installation should be assessed, needs more information than a photograph of the distribution board.
The IET’s discussion of socket outlet RCD requirements explains why socket rating, use and the people likely to use it matter. A business address does not create a general exemption from RCD protection.
For a quote, ask which circuits need attention and why. Request the applicable requirement, the observed condition and the reason for the classification.
Avoid assuming that “no RCD” is always C2 or always C3. Also ask how the proposed arrangement suits the equipment connected to it. A repair should address the relevant safety requirement and be appropriate for the actual installation.
Does a plastic enclosure justify replacing the whole board
An enclosure description alone is too little information to judge a commercial installation. Its condition, position, suitability and the relevant requirements need consideration.
Best Practice Guide 4 distinguishes between circumstances involving combustible consumer units. However, those domestic and similar examples are not a universal commercial coding rule.
Ask the electrician to identify the particular defect or requirement behind the proposed replacement. If the explanation concerns escape arrangements or the surrounding environment, ask how those circumstances affect the assessment of your board.
Do not decide that a board is safe merely because it has a metal enclosure either. The question is whether the assembly and its installation are suitable for continued service.
Is FI the appropriate code for the concern
The IET identifies circuit identification and an established low insulation resistance result as examples where FI can be misused. Work may be needed to trace a circuit or locate the cause of a known defect without FI being the appropriate reporting code.
The distinction affects how the job is described. Are you paying to establish whether a safety defect exists, or to locate and remedy a defect already demonstrated by inspection or testing?
Ask for the existing evidence and the proposed investigation outcome. A vague instruction to “investigate electrics” gives you little control over either scope or cost.
Is a complete board replacement the only possible remedy
It may be the right remedy, but the contractor should explain why. Our consumer unit and distribution board replacement service sets out what a properly specified board change involves. Ask whether a suitable local repair or alteration is available and what makes replacement preferable or necessary in this case.
Compatibility is a real constraint. BEAMA’s guidance on selecting devices for assemblies warns against assuming that devices can be mixed between manufacturers or generations of equipment. The assembly manufacturer’s guidance matters.
A device physically fitting into a board does not establish its suitability. Equally, a quotation should not jump straight to replacement without explaining the condition, design or compatibility issue that drives the recommendation.
If replacement is proposed partly to provide additional capacity for future equipment, ask for that benefit to be identified. You can then assess it alongside the immediate remedial need.
Must every recommendation be completed to clear the report
On an Amendment 4 report, C3 and FI do not themselves produce an unsatisfactory outcome. Ask for recommended improvements and investigations to remain identifiable within the quotation.
You might choose to commission an improvement during the same shutdown as essential repairs. Combining work can be convenient, but the quotation should still explain the different purposes.
If an insurer, landlord or other party requires additional work, request their written requirement. That is a separate reason for considering the work, and it should be described accurately.
Why an installation can be unsatisfactory after passing five years ago
A satisfactory report records the condition found at that inspection, within its stated scope. Five years later, the installation, its use and the information available to the inspector may all be different.
Ask the contractor to compare the relevant observations and results in both reports. There are several possible explanations, and each has a different implication for the remedial quote.
The installation or its use has changed
Damage, deteriorating connections or unsuitable alterations can introduce a safety problem after an earlier inspection. Extra equipment or a change in how the premises is used may also affect whether existing arrangements remain suitable.
HSE’s maintenance guidance stresses the importance of equipment, environment and previous findings. For your quote, ask what change or deterioration has been identified and which evidence supports it.
Requirements have developed since 2021
Two developments illustrate why an inspector may now ask different questions about protection:
- Amendment 2 in 2022: RCD selection requirements were revised, including restrictions on using Type AC devices. The IET explains the relevance of direct current components from connected equipment. Ask whether the fitted protection suits the actual loads and what justifies the reported code. Finding an older device is not enough to assign a blanket C2.
- Amendment 3 in 2024: Requirements were added concerning devices designed for power flow in one or both directions. Electrical Safety First explains their relevance to solar PV and battery connections. If generation or storage has been added, ask whether the protective devices are suitable for the resulting arrangement.
These developments can inform the assessment. They do not automatically require every existing installation to be rebuilt to the latest design standard. The IET’s EICR guidance makes clear that an older installation can remain safe despite differences from newer requirements.
Amendment 4’s 2026 FI change, explained earlier, does not itself provide a new reason for an unsatisfactory result. It changes how investigation is reported.
The inspections covered different things
An earlier report may have had limitations, covered fewer circuits or lacked access to an area included this time. It is also possible that a defect was previously missed or a code needs clarification now.
Do not assume either report is correct simply because it is older, newer or cheaper to act on. Ask the current inspector to explain the finding and any relevant difference in scope or evidence.
Five years is an example here, not a universal commercial inspection interval. For the quotation, the useful question is what now requires action and why.
What a useful quotation should include
An itemised quote need not become a technical manual. It should provide enough information for you and another competent contractor to understand the intended result.
Request the observation number, circuit or location, work description and price for each item or clearly defined group. Where labour is shared across several repairs, a combined cost is reasonable if the grouping is explained.
Ask whether the price includes:
- Materials and any specified replacement equipment.
- Labour, access equipment and agreed working hours.
- Isolation, testing and restoration of the affected circuits.
- Relevant certification or written completion records.
- Making good disturbed surfaces and removing waste, where applicable.
- VAT, exclusions and any provisional allowances.
Agree how extra work will be authorised. If opening an enclosure or accessing concealed wiring may reveal additional defects, ask when the contractor will stop and seek a decision, and how urgent safety action will be handled.
For investigation, request a defined initial scope and a reporting point. For example, you could agree an initial attendance to investigate a named observation, followed by written findings and a separate repair proposal where needed.
Ask about business disruption as part of the scope. Identify equipment that needs an organised shutdown, who can authorise it and who will confirm that normal operation has resumed afterwards.
These commercial details are suggested purchasing controls. They do not replace the electrician’s responsibility to select appropriate technical methods or the business’s responsibility to act on safety findings.
A hypothetical example of two different repair quotes
Imagine that an office receives a report with a C2 observation affecting one identified circuit and a separate C3 recommendation. The first quotation gives a single price for replacing a distribution board and completing all remedial work.
A second quotation proposes work on the affected circuit and prices the C3 improvement separately. Neither proposal can be declared correct from that description alone.
Ask the first contractor which findings require board replacement. Ask the second to explain how the proposed circuit work resolves the observation and whether the existing board can accommodate it safely.
The first contractor might identify a compatibility problem that prevents the proposed smaller alteration. Alternatively, the explanation may show that some of the replacement scope is a worthwhile upgrade you can choose separately.
The useful comparison is the proposed outcome for each observation, including the supporting evidence and verification. Comparing totals before understanding that scope can produce a misleading answer.
Now imagine a workshop quote containing an FI investigation allowance and a provisional price for replacing a cable. Ask whether cable replacement is a confirmed requirement or one possible outcome.
If the defect has not been established, agree what evidence would justify replacement and how you will be told. That helps prevent a provisional possibility being treated as an already proven need.
These are examples of questions to ask, not coding decisions for actual installations. No prices or customer experiences are implied.
Getting a second opinion without delaying safety action
Ask the original inspector for clarification first. A missing explanation can sometimes be resolved through the test results, a fuller description or a corrected document.
If important questions remain, obtain a second opinion from someone competent in the type of installation concerned. The IET inspection and testing guidance emphasises the knowledge and experience required for this work.
Provide the complete EICR, quotation, relevant previous certificates and any written clarification. Include what has already been isolated or repaired so the reviewer understands the present position.
A review of documents may identify an inconsistency, but some disagreements require a site visit and further checks. Agree that scope and fee before commissioning the review.
Do not ask someone simply to produce a cheaper set of codes. Ask them to explain whether the observations and proposed remedies are supported by the available evidence.
Keep existing safety precautions in place while the issue is reviewed. Any change to those precautions should be decided by a competent person who understands the risk.
Your commercial safety duties still apply
For businesses in Great Britain, the Electricity at Work Regulations 1989 are central. HSE guidance on Regulation 4 explains the duty to maintain systems as necessary to prevent danger, so far as reasonably practicable.
The objective is a safe installation. An argument about quotation wording does not remove the need to address an identified risk.
Do not assume that every commercial remedial job has a universal 28 day allowance. Response should reflect the danger and any applicable requirements. An immediate hazard needs immediate action, while C2 requires urgent attention.
HSE’s maintenance guidance also supports using records to monitor condition and maintenance effectiveness. Keep your report, decisions and completion evidence together so the next person responsible for the premises can follow what happened.
For Northern Ireland, consult HSENI’s electrical safety guidance and the separate Electricity at Work Regulations (Northern Ireland) 1991. Do not assume that every legal reference for Great Britain applies unchanged throughout the UK.
If you lease premises, involve whoever controls the affected installation and check the lease arrangements. Where responsibility is disputed, obtain appropriate advice while ensuring identified dangers are addressed.
What should happen after the remedial work
Agree the completion documents before accepting the quote. Ask how each addressed observation will be identified and what inspection or testing will verify the work.
Depending on the work, the appropriate record may include an Electrical Installation Certificate or a Minor Electrical Installation Works Certificate. The IET model forms distinguish these documents from an EICR, which reports on condition.
The IET also describes retaining remedial certification with the original EICR. That article discusses rented housing, but its explanation of the relationship between the documents is useful here. Its housing specific legal timetable should not be imported into a commercial quotation.
A further complete EICR is not automatically the only way to document repairs. Ask why one is proposed, what it will cover and whether the report recipient has specified a particular requirement.
Retain the original report rather than treating a paid invoice as a replacement for it. Request a clear record of the observations addressed, the work completed, relevant test results and anything still outstanding.
Where an investigation produces findings, keep its outcome too. You should be able to tell whether the concern was resolved, whether a defect was identified and whether additional work remains necessary.
Questions to send with your quotation query
You can adapt the following wording when asking a contractor for clarification:
“Please link each quoted item to the relevant EICR observation and circuit or location. Please identify the work needed for C1 or C2 findings, any investigation and any recommended improvements separately.
“For proposed board or cable replacement, please explain the evidence supporting replacement and whether a suitable smaller repair has been considered. Where investigation is needed, please state the initial scope, cost and point at which further expenditure will need agreement.
“Please also confirm the required shutdown, what is included in the price, the testing after completion and the documents we will receive. Please identify any immediate precautions we must maintain while the work is arranged.”
Send the report reference and quotation reference with your message. Keeping the exchange attached to the same documents makes later decisions easier to understand.
Questions business owners ask about remedial quotes
Can another electrician quote for the work
You can seek an alternative proposal. Supply the full report and expect the contractor to make the checks needed to take responsibility for their own work. A visit may be necessary before a reliable quotation can be given.
Should an EICR remedial quote include every C3 item
It can include them, provided their purpose and cost are clear. A C3 recommendation does not itself make the EICR unsatisfactory. Consider its benefit and any separate requirements applying to your premises when deciding what to commission.
Can an FI investigation be charged separately
Yes, provided the agreed scope and charging arrangements support that. Ask what the inspection already established, what further investigation will establish and whether the quotation includes any resulting repairs. The word FI alone does not define a price or an unlimited scope of work.
How can I tell whether the price is reasonable
Compare sufficiently detailed quotations covering equivalent work. Check access, working hours, equipment, verification and exclusions before comparing totals. An unexplained price difference is a reason to ask questions, rather than evidence by itself that either contractor is wrong.
Does a satisfactory result settle every maintenance question
No. Read the report’s scope, limitations and recommendations, and continue to act on new damage or changing conditions. Use the inspection findings as part of maintaining the premises rather than treating the result as a substitute for ongoing attention.
