EICR Testingin Sutton
Inspection and testing of an existing electrical installation, ending in a written report you can act on or hand to a tenant.
An EICR, or Electrical Installation Condition Report, is the standard way to find out whether the wiring in a property is still safe to use. If you need an EICR in Sutton, TH Electricians LTD is a qualified electrical firm based in Sutton. We inspect and test homes, rented properties and commercial premises, then give you a written report explaining what we found and what, if anything, needs to be put right.

EICR Sutton: what the inspection covers
An EICR is an inspection and test of an installation that already exists. It is not a check on new work. The electrician looks at the consumer unit, the visible wiring, sockets, switches, lighting and earthing, then carries out tests on the circuits to see how they are performing.
The point is to spot damage, wear and deterioration, and anything that no longer meets the standard it should. Some faults cannot be seen by eye, which is why the testing matters as much as the looking. Parts of the property may need to be accessed, so it helps to tell us early about locked rooms, lofts or outbuildings that have their own supply.

Why the power is switched off for part of the visit
Testing circuits properly means isolating them, so the electricity will be off to some or all of the property for stretches of the inspection. We plan the order of the work with you beforehand so the disruption is kept to what is needed.
- Tell us about anything that must stay on, such as refrigeration, a fish tank or medical equipment.
- Computers and other sensitive equipment are best shut down before we start.
- In a let property, the tenant should be told when the inspection is planned.
Agreeing these points in advance makes the visit smoother for everyone in the building, and it means nothing important is switched off by surprise. If the property is occupied by tenants, a little notice from you or your agent goes a long way.

Understanding the codes in your report
The report grades anything it finds using observation codes. It is worth knowing what they mean before you read yours.
- C1: danger is present and there is a risk of injury. Immediate action is required.
- C2: potentially dangerous. Urgent remedial work is needed.
- C3: improvement recommended. It is not a fault, but the installation could be better.
- FI: further investigation required, because something could not be fully judged during the inspection.
We talk through the findings with you rather than just handing over a document, so you know which items matter most and why.

Landlords and the five-year rule
Private landlords in England must have the electrical installation in a rented property inspected and tested at least every five years. A copy of the report has to be given to the tenants, and a copy to the local authority if it asks for one.
Landlords who let more than one property often find it simplest to keep a record of every date, so that a certificate never runs out unnoticed. If you are taking on a tenancy or a new property, it is worth checking when the last report was done and whether it was satisfactory. We can carry out the inspection and, where the report calls for it, the remedial work as well.

If the report comes back unsatisfactory
An unsatisfactory result means the report has found something coded C1, C2 or FI that has to be dealt with. That is not unusual with an older installation, and it is far better to find it on paper than after a fault.
Remedial work has to be completed before the installation can be treated as satisfactory. Common items include worn or damaged accessories, missing protection, poor connections and out-of-date consumer units. We can explain what each item involves and price the work once we have seen it. When the work is done, the installation is checked again so the paperwork reflects the corrected state, not the old one.

Homes, commercial premises and buying or selling
An EICR is not only for landlords. Homeowners choose to have one done when they buy an older property, before a renovation, or when the wiring has never been looked at. A report gives a clear picture of the condition of the electrics so that decisions are made on facts.
Shops, offices and other commercial premises also benefit from a periodic inspection, particularly where the installation has been altered over the years. We are based in Sutton and cover the towns listed on our Areas We Cover page. Tell us what type of property it is, whether it is let, and when the last report was done, and roughly how many floors are involved, and we can advise how the visit will run.

EICR questions we are asked
How often is an EICR needed?
For a private rented property in England, at least every five years. For your own home there is no fixed legal date, but an inspection is sensible when you buy an older house, before major work, or if the wiring has never been checked.
Does the tenant get a copy of the report?
Yes. A private landlord in England must give tenants a copy of the report. It is good practice to keep your own record too, so you can show when the last inspection was done and what it found.
What happens if the report lists C2 items?
A C2 means the installation is potentially dangerous and needs urgent remedial work. The report is unsatisfactory until it is put right. We can explain each item, quote the work and re-check the installation once it is finished.
Will the power be off during the inspection?
Some circuits have to be isolated for testing, so yes, for parts of the visit. We agree the order of work with you first, and you should tell us about any equipment that must stay running.
