EICR electrical testing at a consumer unit, calibrated tester and meter in hand
An EICR tests every circuit in the property with calibrated meters, then records the result as satisfactory or unsatisfactory.

An EICR is the formal health-check for the electrics in a property. Whether you are a homeowner trying to understand why your solicitor is asking for one, a landlord renewing a five-year report, or someone who has just had one come back unsatisfactory and does not know what to do next, this guide is written for you. Plain English, the codes explained properly, and what to expect on the day.

What is an EICR?

EICR stands for Electrical Installation Condition Report. Think of it as an MOT for your electrics. A qualified electrician visits the property, tests every circuit with calibrated meters (lighting, sockets, cooker, shower, immersion, the lot), and issues a formal written report against the current edition of the UK Wiring Regulations, BS 7671:2018+A4:2026 [1].

The report records the condition of the installation, notes any issues with standardised codes, and declares the overall outcome as satisfactory or unsatisfactory. It is not a hunt for extra work. If everything is in order, we say so.

Who needs an EICR?

Landlords: legal requirement

Every privately rented property in England has been required to hold a valid EICR since 1 April 2021, under the Electrical Safety Standards in the Private Rented Sector (England) Regulations 2020 [2]. The maximum interval between inspections is five years, tenants must receive a copy within 28 days, and fines for non-compliance reach up to £40,000 per property per breach.

Homeowners: strongly recommended

There is no legal obligation for an owner-occupier. The recommendation is an EICR every ten years, or sooner if your home is older, you have just moved in, or you have noticed symptoms like flickering lights, repeated trips, or a burning smell near sockets.

Buying or selling a property

Not mandatory, but increasingly expected at conveyancing. A satisfactory EICR is the single strongest electrical document in a sale pack. See the dedicated selling your house electrics guide for the TA6 walkthrough and the full pre-sale checklist.

Commercial premises and HMOs

Commercial and HMO properties are generally expected to hold an EICR at a maximum interval of five years, both as part of a duty of care and as a common insurer requirement.

The law for landlords, in detail

The 2020 regulations apply to every tenancy in England that grants one or more people the right to occupy the property as their main residence, other than a short list of exclusions (lodgers, social tenancies, some student halls). The key obligations [2]:

  • An EICR must be carried out before a new tenancy begins, and thereafter at a maximum interval of five years.
  • A copy of the report must be supplied to new tenants before occupation, and to existing tenants within 28 days of the inspection.
  • The local authority can request a copy within seven days of asking.
  • Remedial work against C1, C2 or FI codes must be completed within 28 days (or a shorter period if the report specifies one), and written confirmation of completion sent to the tenant and the local authority.
  • Failure to comply carries fines of up to £40,000 per breach.

What I test on the day

  1. Visual inspection of the installationWe walk the property, check the consumer unit, main isolator, tails, main earth and bonding, and every accessible accessory. Many issues show up at this stage without test equipment.
  2. Ze and Zs loop impedanceWe measure earth fault loop impedance at the origin (Ze) and at the farthest point of each circuit (Zs) with a calibrated tester. The numbers confirm whether the circuit will trip fast enough under a fault.
  3. Insulation resistanceEvery circuit is isolated and tested live-to-earth and live-to-neutral at 500 V DC. Readings below 2 megohms warrant attention; below 1 megohm is a C2.
  4. Polarity and continuityEvery accessory is checked for correct polarity, and every protective conductor is confirmed continuous end to end.
  5. RCD and RCBO operationEvery residual current device is tested at 30 mA and 150 mA, and the monthly test button is operated. Drifted trip times, or a button that does not fire the mechanism, fails the device.
  6. Report and observation codesAll results are recorded on the BS 7671 schedule of test results, observations coded C1, C2, C3 or FI, and the overall outcome marked satisfactory or unsatisfactory. You get the report by email and a printed copy.

C1, C2, C3 and FI observation codes

EICR observation codes and what they mean for your report
CodeMeaningEffect on the reportWhat has to happen
C1Danger present, risk of injuryUnsatisfactoryMake safe immediately, often on the day. Notify the tenant or occupant.
C2Potentially dangerous, remedial requiredUnsatisfactoryPlan and complete remedial work before the installation is relied upon.
C3Improvement recommended, not urgentSatisfactoryOptional. Often deferred or scheduled with the next maintenance.
FIFurther investigation requiredUnsatisfactory until clearedReturn visit to complete the test or open up a concealed element.

One of the most common misunderstandings: a report can carry a long list of C3s and still be satisfactory. One C2 or FI, and it is unsatisfactory. That single word is what the landlord, buyer or insurer reads first.

Common findings on York EICRs

Six issues account for most of the C1 and C2 codes I see on York pre-sale and rental EICRs:

Common EICR findings and typical remedial
FindingTypical codeTypical remedial
No RCD protection on socket or lighting circuitsC2RCBO retrofit on the circuit, or full consumer unit upgrade
Plastic consumer unit in a flat or HMOC2Replace with a metal enclosure to current BS 7671
Main earth or main bonding undersized or missingC2Upgrade to 16 mm main earth and 10 mm bonding
Rubber-insulated pre-1960s cable still in useC2Rewire the affected circuits or the whole property
Loose or damaged accessory on an outdoor or bathroom circuitC2Replace the accessory and retest the circuit
Consumer unit schedule missing or illegibleC3Relabel and update the schedule

What if your property fails an EICR?

Don't panic. A lot of properties come back unsatisfactory, it does not mean the house is about to burn down, it means an issue has been identified and now you know about it. We explain every code in plain English, estimate the remedial work in writing, and you decide what to do.

For rental property, the 28-day clock starts from the date of the report. I can usually fit the remedial work into that window. Once it is done, I re-test the affected circuits and re-issue the certificate.

C3 codes are advisory. There is no obligation to act, but I'll always note what I would recommend and why.

How often do you need an EICR?

Recommended EICR intervals by property type
Property typeMaximum intervalLegal or advisory?
Privately rented domestic (England)5 yearsLegal requirement
Owner-occupied domestic10 yearsAdvisory
Owner-occupied domestic, pre-saleNo rule, less than 5 years preferredAdvisory, increasingly expected
Houses in Multiple Occupation (HMOs)5 yearsLegal requirement plus licensing
Commercial premises5 yearsAdvisory, often insurer-required
Industrial premises3 yearsAdvisory, often insurer-required

A note on cost

Every EICR is scoped on the property. Cost depends on circuit count, the age and type of the consumer unit, whether the property has any special locations (bathrooms, HMO flats, outbuildings), and how accessible the wiring is. I give you a clear written rate when I confirm the booking. Book an EICR.

A note for landlords and letting agents

I regularly present to York landlord associations about EICRs, the legal framework and how to stay on top of a rolling portfolio without the stress. If you manage multiple properties, I can set up a scheduled rolling programme so nothing drops off at renewal time. Every report is delivered in the format your local authority expects, and I liaise with tenants direct on access when you need us to.

I run EICRs across York every week, from owner-occupied terraces to managed portfolios. Every report arrives with plain-English notes against each code, not just the standard BS 7671 phrasing, so you and your solicitor or local authority know exactly what is being flagged. More about me.

Need an EICR in York?

Whether it is one property or twenty, I'll make it straightforward. Rolling schedules for portfolios, tenant-direct access, full local-authority-ready paperwork.

Frequently asked questions

What is an EICR?

An EICR (Electrical Installation Condition Report) is a formal inspection and test of the electrical installation in a property. A qualified electrician tests every circuit against BS 7671:2018+A4:2026 and issues a written report with observation codes against any issues found.

Do landlords legally need an EICR?

Yes. Since 1 April 2021 every rental property in England has required a valid EICR at a maximum interval of five years, under the Electrical Safety Standards in the Private Rented Sector (England) Regulations 2020. Tenants must receive a copy within 28 days of the report. Local authority fines can reach £30,000 per property per breach.

Do homeowners legally need an EICR?

No. There is no legal requirement for an owner-occupier to hold an EICR. It is recommended every ten years, or sooner if the property is older, you have just moved in, or you have noticed symptoms such as flickering lights, repeated trips or a burning smell. Buyers and their solicitors increasingly ask for one at sale.

How often do I need an EICR?

Rented domestic property: at least every five years. Owner-occupied domestic property: every ten years as a recommendation. Commercial premises: every five years as a general rule, or as specified by your insurer. HMOs and student accommodation: every five years.

What happens during an EICR?

We isolate each circuit in turn at the consumer unit, measure insulation resistance, earth fault loop impedance, polarity and (for RCDs) trip times, and visually inspect the consumer unit, accessories and cabling. On a typical three-bedroom house it takes two to three hours. Power is off in the area being tested while each circuit is measured.

What do the C1, C2 and C3 codes mean?

C1 means danger is present, with a risk of injury, and requires immediate action. C2 means potentially dangerous, remedial work is required. C3 means improvement recommended but not urgent. FI means further investigation is needed before the report can be finalised. A report is unsatisfactory if it carries any C1, C2 or FI codes.

What happens if my property fails an EICR?

An unsatisfactory report does not mean the property is unsafe today, it means issues have been identified. We explain what each code means and estimate the remedial work. For rental property, landlords must complete remedial works within 28 days (or a shorter period if the report specifies one), and send the updated evidence to the tenant and local authority.

How long does an EICR take?

A typical three-bedroom house takes two to three hours. Larger properties, commercial premises, and homes with more circuits or older wiring take longer. I confirm timing during the booking so you can plan around the power being off in parts of the house.

Do I need to be home during an EICR?

For an owner-occupied property, yes, we need access to every room and the consumer unit. For rental property, most landlords arrange access with tenants in advance. We also work directly with letting agents and property managers.

Can you do remedial work after the EICR?

Yes. Any remedial work flagged on the report can be scoped and estimated separately. I give you a written estimate before the work starts, and re-test and re-issue the certificate once the remedial is complete.

How do I book an EICR in York?

Contact me by phone, WhatsApp or the booking form with the property address, type of property (owner-occupied, rental, commercial), approximate circuit count if known, and whether you have any recent electrical certificates. I confirm the timing and rate before I come out.
