The short answer
The cost to fix EICR faults varies enormously because it depends on what the report records. Minor remedials — a faulty socket, missing earth bonding, or a loose connection — might be £50–£200, often covered in a short return visit. A consumer unit (fuse board) replacement, a common fix for an unsatisfactory result, typically runs £350–£700+. Larger problems flagged across multiple circuits can point toward a partial or full rewire, which runs into the thousands. Because the EICR is an inspection only, the remedial work is always quoted separately once the faults are known. These are typical ranges for guidance, not quotations.
An EICR tells you what needs putting right but does not include the cost of doing it. The remedial bill depends entirely on the faults recorded, which is why estimates only become reliable once you have the report in hand.
Typical remedial cost ranges
- Minor repair~£50–£200
- Consumer unit replacement~£350–£700+
- Several circuits affectedinto the thousands
- Partial / full rewire£2,500–£12,000+
- Quotedseparately, after the report
Why the range is so wide
A C1 (danger present) or C2 (potentially dangerous) can be anything from a single loose terminal to wiring at the end of its serviceable life across the whole property, and the cost to remedy tracks that span exactly. A quick fix like re-terminating a connection or replacing a damaged accessory is inexpensive and often done in a single short return visit. A worn consumer unit without modern RCD protection is a more defined job with a fairly predictable price, because it is a known piece of work with standard parts and labour. But where the report records the same fault across many circuits — degraded insulation, an absence of earthing, or wiring that no longer meets BS 7671 — the remedy may be a partial or full rewire, which is a different order of cost entirely.
The crucial point is that the report itself tells you which end of the scale you are at, because each observation carries a code and a description. A report with two C2 items against named circuits points to a contained, predictable bill; a report that flags the same deterioration on circuit after circuit is signalling something more fundamental about the installation's age and condition. That is why a reliable remedial estimate is impossible before the inspection and usually quick to produce after it: the electrician is no longer guessing, but pricing against a specific, written list of faults.
| Remedial item | Typical cost | Notes |
|---|---|---|
| Faulty socket / switch | ~£50–£150 | short visit |
| Earth bonding upgrade | ~£100–£250 | common C2 fix |
| Consumer unit replacement | ~£350–£700+ | RCD/RCBO protection added |
| Partial rewire | ~£2,000–£5,000 | some circuits |
| Full rewire | ~£2,500–£12,000+ | whole property |

Why it is quoted separately
The EICR fee covers the inspection and report only. The electrician cannot price the remedial work until they know what the faults are, so the quote for putting things right comes after the report rather than as part of the inspection fee. This split is entirely normal and, importantly, it protects you: it means the inspection is impartial rather than a sales visit, because the person assessing the installation is not pricing the fix at the same moment they decide whether it passes. The report records what it finds on its merits, and the remedial quote follows as a separate, transparent step.
That separation also gives you genuine choice. You are free to take the remedial work to a different registered electrician if you wish, provided they carry it out competently and certify it correctly with the appropriate certificate. Getting a second quote on the remedial work is a reasonable thing to do, especially for a larger job like a rewire, and it does not affect the validity of the original report. For landlords, an unsatisfactory result triggers a duty to complete the remedial work within the timescale the report sets — typically 28 days unless a shorter period is specified — and to obtain written confirmation that the work has made the installation satisfactory.
Spreading the work
Not every observation has to be tackled at once, and the codes themselves tell you what is urgent and what can wait. A C1 (danger present) needs urgent action — a competent electrician usually makes a C1 safe before leaving the property, because it represents a risk of injury here and now. A C2 (potentially dangerous) must be put right for the report to become satisfactory, but it does not generally carry the same immediate emergency as a C1, so it can be scheduled within a sensible window rather than fixed on the spot.
C3 items are improvement recommendations, not failures, so they can be planned for later without affecting the satisfactory result. Where a report records several C3 improvements, it can make sense to bundle them with other planned work — a kitchen refit, a redecoration, or the next consumer unit upgrade — rather than treat them as emergencies and pay for separate visits. There is also an FI code, for further investigation, which means the electrician needs to look more closely before a final view can be reached; that is a prompt for additional inspection rather than a priced remedy in itself. Reading the codes correctly lets you sequence the work by genuine priority and spread the cost sensibly, instead of treating every line on the report as an immediate bill.
Sequencing also helps you avoid paying twice for access. Several smaller remedials that each need a floor lifted, a wall chased, or a circuit isolated are cheaper done together in one visit than spread across separate call-outs, because the disruptive part is shared. So while the codes tell you what is urgent, the practical layout of the work can tell you what is worth bundling — a C2 that has to be done anyway, fixed at the same time as a C3 improvement in the same room, often costs less combined than tackled months apart. The exception is the C1: it should never be left waiting for a convenient slot, because it represents a present danger and is the one item where timing is not a matter of budget.
Keeping remedial costs sensible
There are fair ways to keep the remedial bill reasonable without compromising safety. The first is to get the work itemised against the report, so you are paying for defined fixes rather than an open-ended lump sum, and so you can weigh up quotes on the same basis. The second is to distinguish the must-do from the nice-to-have: the C1 and C2 items are what make a report unsatisfactory and therefore have to be done, while C3 recommendations are genuinely optional and can be timed to suit your budget and other plans.
What is not worth doing is leaving a C1 or C2 unaddressed to save money, especially in a let property, because the duty to make the installation safe does not go away and an unsatisfactory report left unactioned is itself a problem. Equally, it is worth being a little cautious about a remedial quote that jumps straight to a full rewire when the report only flags a handful of circuits — a second opinion from another registered electrician can confirm whether the larger job is genuinely needed or whether a more contained repair would resolve the coded faults. The most cost-effective route is almost always the one that fixes exactly what the report records, certified properly, rather than either under-doing the urgent work or over-doing the optional work.
One further point keeps the spend sensible: make sure the remedial work is certified correctly once done. A repair that puts right a coded fault should produce the appropriate paperwork — a Minor Works Certificate for a contained job, or an Electrical Installation Certificate for larger work — and, where the EICR was unsatisfactory, written confirmation that the installation is now satisfactory. That certification is not an optional add-on padding the bill; it is the evidence that the fault has actually been resolved, and for a landlord it is the document that discharges the legal duty triggered by the original report. Paying for the fix without securing the certificate leaves you with the cost but not the proof, which is a false economy whatever the size of the job.
Frequently asked questions
How much does it cost to fix an unsatisfactory EICR?
It depends entirely on the faults recorded. Minor repairs might be £50–£200, a consumer unit replacement around £350–£700 or more, and widespread problems can mean a partial or full rewire costing thousands. The remedial work is quoted separately after the report.
Is the cost of fixing faults included in the EICR price?
No. The EICR fee covers the inspection and report only. Remedial work to put right any C1 or C2 fault is quoted separately once the electrician knows what needs doing, which keeps the inspection impartial.
Do I have to fix every code on an EICR?
A C1 needs urgent action and a C2 must be put right for the report to become satisfactory. C3 items are improvement recommendations, not failures, so they can be planned for later rather than treated as emergencies.
