ComGas carries out Electrical Installation Condition Reports for homeowners and landlords across Farnham and the surrounding area, classifying every observation clearly and explaining what it actually means before any remedial work is discussed. Landlord reports are prepared to meet the five-year duty for privately rented homes.
A report that tells you what's actually happening in the wiring — not a pass/fail sticker.
An EICR is a periodic inspection and test of the fixed electrical installation in a property — the wiring, the consumer unit, the earthing and bonding arrangements, and the circuits themselves. It's carried out against BS 7671, the current wiring regulations, and every finding is recorded with a specific observation code so it's clear exactly what was found and how seriously it needs treating.
It doesn't test portable appliances, extension leads or anything plugged in rather than wired in, and it doesn't mean nothing will ever go wrong afterwards — it's a documented assessment of the installation's condition at the time of the inspection. We explain what each classification on your report actually means, so you're deciding on genuine information rather than a single overall verdict.

How an EICR works
Classification, landlord duty, scope and what happens next.
Every EICR follows the same structure: inspect and test against BS 7671, classify each observation consistently, and explain what it means for you before quoting any remedial work.
Understanding C1, C2, C3 and FI
Every observation on an EICR is given a specific classification, and the classification — not a general impression of the property — determines how urgently something needs attention.
Landlords of rented residential homes have a specific legal duty around electrical safety that owner-occupiers don't, and it's tied to a fixed inspection cycle rather than being discretionary.
Electrical installations in privately rented homes must be inspected and tested at least every five years
A copy of the report must be given to existing tenants, and to new tenants before they move in
Any C1 or C2 observation must be remedied within the timescale set out on the report, and confirmation provided
The same report and duty applies whether the property is let directly or through an agent
Being clear about the boundary of an EICR matters, because a report that passes doesn't mean everything electrical in the home has been checked.
Covers the fixed wiring, consumer unit, earthing and bonding, and the condition of accessories such as sockets and switches
Does not cover portable appliances — kettles, washing machines, lamps — which fall under separate portable appliance testing if required
A satisfactory report reflects the installation's condition on the day of inspection, it doesn't promise the installation will remain fault-free afterwards
Some existing installations are compliant with the edition of the regulations in force when they were installed without needing to be brought up to the current edition
A report with observations isn't a demand to rebuild the installation — it's a prioritised list, and we work through it in the order the classifications set.
C1 observations are addressed as a priority, followed by C2, with C3 items discussed and left to your decision
Remedial work is scoped and quoted separately from the inspection itself, item by item
Once remedial work is complete, the relevant circuits are retested and the report updated or a completion certificate issued for that work
FI items are investigated properly rather than left unresolved on the report
An EICR classification is not a pass/fail verdict on the whole house.
It's tempting to read an EICR as a single result — satisfactory or unsatisfactory — but the substance of the report is in the individual classifications, not the headline. A property with a single C3 recommendation and nothing else is in a genuinely different position from one with several C2 observations, even though both might carry the same overall 'unsatisfactory' outcome if any C1 or C2 is present at all. Treating every unsatisfactory report as equally serious leads to either unnecessary alarm or, just as often, delaying attention to something that does need addressing.
This is why we go through each classification individually rather than just handing over the headline result. A C1 needs acting on straight away because there's a danger present now. A C2 is potentially dangerous and needs remedying urgently, but it isn't the same as an active hazard. A C3 is worth doing at a sensible point but isn't a safety failure. Knowing which is which is what lets you make a sensible decision about what to prioritise and what can be planned in.

Incredible service — problems fixed perfectly once again.
Lee, Paul and the team at COMGAS are fantastic. They arrived on time and got straight to work, quickly identifying the root cause of the plumbing and heating issues I was experiencing.
The problems were diagnosed swiftly, I was kept fully informed throughout, and both issues were fixed with impressive speed and precision.
Having worked in the industry for nearly 20 years, I know how rare it is to find reliable, trustworthy, and genuinely skilled professionals — let alone a team this good.
I joked about it at the time, but it’s true: I had the best shower I’ve ever had in this house after they finished the job — and I’ve lived here for 10 years!
I honestly couldn’t ask for more and can’t recommend COMGAS highly enough.

I recently used Comgas for a gas and heating service, and I couldn't be more impressed! From start to finish, their team was professional, friendly, and highly knowledgeable. They quickly identified the issue with my heating system and explained everything in detail, offering both short- and long-term solutions.
The technician was punctual and took extra care to ensure everything was running smoothly. I really appreciated their attention to detail and how they made sure to clean up after the work was completed. My home is now warm and cozy, all thanks to their expert service. I highly recommend Comgas for anyone looking for reliable, efficient, and trustworthy gas and heating professionals!

EICR questions
Frequently asked questions.
If you need an EICR for a rented property, or you're not sure what a report you've already received actually means, get in touch and we'll talk it through.
C1 means a danger is present now and needs immediate action. C2 means something is potentially dangerous and needs urgent remedial work. C3 is an improvement recommendation, not a safety failure. FI means further investigation is needed to establish whether a danger actually exists.
Do landlords legally need an EICR?
Yes. Landlords of privately rented homes must have the electrical installation inspected and tested at least every five years, provide a copy to tenants, and remedy any C1 or C2 findings within the timescale the report specifies.
How often does an EICR need renewing?
For rented properties, at least every five years, or sooner if the previous report specifies an earlier date. For owner-occupied homes there's no fixed legal interval, though a similar five-yearly cycle is a reasonable benchmark.
Does an EICR check my appliances?
No. An EICR covers the fixed wiring and installation — the consumer unit, circuits, sockets and switches — not portable appliances like kettles or washing machines, which are covered separately by portable appliance testing if you need it.
What happens if my report comes back with C1 or C2 observations?
We scope and quote the remedial work required for each observation separately, prioritising anything classified C1. Once the work is complete, the affected circuits are retested and the documentation updated.
Is an EICR the same as a rewire?
No. An EICR is an inspection and test of the existing installation. Whether any remedial work follows — anything from a single accessory replacement to a full rewire — depends entirely on what the inspection finds.
Can I get an EICR for my own home even though I'm not a landlord?
Yes. There's no legal requirement for owner-occupiers, but a periodic condition report is a reasonable way to check the installation, particularly in an older property or ahead of buying or selling.
