Understand the true condition of your electrical installation.
An Electrical Installation Condition Report (EICR) gives you a factual, documented assessment of the wiring and electrical system at a property — identifying what is sound, what needs attention and whether anything presents an immediate concern. ComGas carries out EICRs and periodic electrical testing for commercial premises, landlords and managed property across Surrey and surrounding counties, with findings clearly classified and any remedial work discussed and quoted separately.
Inspection first — remedial work is a separate conversation
An EICR reports the condition of the installation. It does not automatically commit you to further work.
An Electrical Installation Condition Report is an inspection of the existing wiring, accessories, consumer unit or distribution board, earthing and bonding at a property. The engineer tests, records and classifies the condition of the installation. The result is a written report — not an automatic schedule of work. Where findings require attention, they are classified by urgency and explained clearly, and any remedial work is separately discussed and quoted before anything further is authorised.
ComGas carries out EICRs and periodic electrical testing for commercial premises where planned inspection forms part of good practice or a tenancy requirement, for landlords with obligations for let residential and commercial property, and for facilities and property managers who need inspection coordinated across a portfolio.
Homeowner and pre-purchase electrical checks for private homes are covered separately under EICR & Electrical Safety in our residential section.

EICRs and periodic testing for commercial premises, landlords and managed property.
Whether you run a single building, a let property or a managed portfolio, we can assess the condition of the electrical installation and explain clearly what the findings mean.
Commercial EICR
Periodic electrical inspection and condition reports for commercial premises, offices and industrial sites, with all findings classified and clearly explained.
Where an EICR or electrical investigation identifies a requirement for further work, ComGas can separately discuss, quote and carry out the appropriate remedial work.

Condition reports that reflect the installation as it actually is.
Commercial electrical installations vary considerably — in age, complexity and the demands placed on them. A periodic inspection records what is present, tests its condition and identifies areas that present a concern or fall below current standards. Findings are classified by severity: items requiring immediate attention are distinguished from recommendations for improvement that are not immediately dangerous.
Not every observation in a report requires immediate action. A clear written record gives those responsible for the building a documented baseline — useful for planning maintenance, satisfying insurance requirements, supporting tenancy obligations and tracking the condition of the installation over time.
Electrical checks for landlords — findings explained, no assumptions made.
Landlords have a responsibility to ensure the electrical installation at a let property is in a satisfactory condition. An EICR documents the condition of the wiring and system at the time of inspection. Where the report identifies items requiring remedial attention, ComGas explains the findings and provides a separate quotation for any work — the condition report itself does not automatically authorise or commit to further expenditure.

Matt from ComGas Services UK Ltd was very professional, polite, friendly and quick installing a new shower in my bath (and at a better height for me) and a much easier press-in plug for my sink! He left the place spotless. This is the kind of service and installation people dream about - a 5 star service (see photos).

I have used Comgas twice and both times have been very happy with the service. Very friendly and honest. The most recent time, the job turned out to be a lot bigger than they initially thought but it was no issue and Paul stayed the extra time to make sure the job was done properly! He was really tidy, took a lot of care with the work that was done and took the time to explain what he was doing and why. Pleased to have found a reliable heating company!

Fantastic experience from the chaps at ComGas! Special thanks to Matt who removed an old boiler and replaced with a new energy efficient to satisfy the demands of a five bed house with a few bathrooms/baths and showers. The ComGas admin team and Lee were fantastic too on the booking and administration side of things!

Here at St Joseph's we have worked with Comgas for a number of years. They have completed big projects and undertake regular maintenance for our school. They price fairly, and their work is completed to a very high standard. All the engineers carry a DBS which makes life so much easier when trying to book an engineer visit.
On the rare occasion that we have an emergency I can trust that Lee will get one of his engineers to respond quickly and efficiently.
Nothing is too much trouble and no job is too small.

EICR FAQs
Questions about electrical testing and condition reports
Common questions about EICRs, periodic testing and what to expect from the process.
An Electrical Installation Condition Report involves a visual inspection and testing of the existing wiring, accessories, consumer unit or distribution board, and earthing and bonding arrangements. The engineer records observations and classifies any concerns by severity.
What do the EICR observation codes mean?
Observations are typically classified as C1 (danger present — requires immediate action), C2 (potentially dangerous — requires urgent attention), C3 (improvement recommended but not immediately dangerous), or FI (further investigation required before a code can be assigned). Each classification and its practical meaning is explained in the written report.
Does an EICR mean I have to carry out work?
No. An EICR reports the condition of the installation at the time of inspection. Where remedial work is recommended, it is separately discussed and quoted — the condition report itself does not authorise or commit you to additional expenditure, and not every observation requires immediate action.
How often should a commercial electrical installation be tested?
Recommended intervals depend on the type of property and the installation. Let residential properties require an EICR at least every five years under current regulations. Commercial and industrial properties are typically tested on a periodic basis agreed with the building owner or manager. ComGas can advise on the appropriate interval for a specific property.
Can ComGas carry out remedial work identified during an EICR?
Yes. Where an EICR identifies items requiring remedial attention, ComGas can discuss the findings and provide a separate quotation for the appropriate work. Remedial work is always independently scoped and priced from the inspection itself — the two are distinct stages.
Do you carry out EICRs on private homes?
Yes, but through a different page. Homeowner and pre-purchase electrical checks are covered under EICR & Electrical Safety in our residential section. This page covers commercial premises, let property and managed portfolios.
Need a commercial EICR, periodic test or landlord electrical check?
Tell us the property type, approximate age of the installation and any deadlines or access requirements. We can advise on the most appropriate approach and arrange a convenient inspection date.
