Domestic rewires, consumer unit upgrades, new circuits, EICRs and electrical fault finding for homeowners and landlords across Farnham, Surrey and the surrounding area — delivered by the ComGas residential team alongside our gas, heating and plumbing services. For commercial and industrial electrical work, please see our Electrical Installation page.
Safe, practical home electrical services — not a one-size commercial approach.
Residential electrical work demands a different approach from commercial or industrial installations. Consumer unit upgrades, domestic rewires, ring-circuit additions and landlord EICRs are governed by the same regulations, but the context — an occupied home, a rented property, an extension in progress or a renovation — shapes how we approach the job, what we recommend and how we explain the findings.
At ComGas, residential electrical work sits alongside our gas, heating and plumbing teams. Whether you are updating a fuseboard, completing a full rewire, arranging a landlord electrical check or chasing down a fault, you deal with the same ComGas team who can also co-ordinate gas or plumbing work at the same property if it is needed. For commercial and industrial electrical services, see our dedicated Electrical Installation page.
ComGas Services UK Ltd Residential electrical services from Farnham, Surrey.
Home electrical services
Consumer units, rewires, electrical safety checks and fault finding for homes.
From a single circuit addition to a full rewire or landlord safety check, our residential electrical team can advise on the right approach and carry out the work to a consistent standard.
Consumer Unit Upgrades
Assessing, recommending and replacing the fuseboard or consumer unit in your home, including modern RCD and RCBO protection.
Electrical Installation Condition Reports for homeowners and landlords — a documented assessment of the wiring and installation, with findings classified and explained clearly.
EICR for owner-occupied homes
Landlord and rented-property electrical checks
Written condition report with observation classifications
Wiring that keeps pace with how your home is used today.
An older consumer unit may not offer the level of protection a modern installation requires. We assess what is in place, explain what a replacement would involve and carry out the work with minimum disruption to the household. A completion certificate is issued when the work is done.
For properties requiring a rewire — because of age, condition, a planned renovation or a change of use — we scope the work around occupancy, room-by-room access and any other trades working at the property at the same time.
Consumer unit assessment and upgrade
Modern RCD and RCBO circuit protection
Full and partial domestic rewires
Extension, loft and conversion wiring
Co-ordination with gas and plumbing works where required
Completion documentation issued on conclusion of the work
A clear picture of the electrical condition at your property.
An Electrical Installation Condition Report records the condition of the wiring and electrical system at the time of inspection. It is not an automatic schedule of remedial work — findings are classified and explained, and any required remedial work is separately scoped and quoted before anything further is authorised.
An EICR documents the condition of the installation at the time of inspection. Remedial recommendations are separately discussed and priced — not every observation requires immediate action.

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.

Residential electrical FAQs
Questions about home electrical services
Common questions about domestic rewires, consumer units, EICRs and fault finding for homes.
How is your residential electrical service different from your commercial work?
Our residential service focuses on domestic consumer units, ring circuits, rewires and home EICRs for homeowners and landlords. Our commercial and industrial electrical service covers distribution boards, three-phase systems and compliance installations for business premises — the two are distinct in scope and content and are described on separate pages.
Do you carry out EICRs for rented homes?
Yes. We carry out Electrical Installation Condition Reports for landlords of residential properties. The report documents the condition of the installation at the time of inspection and classifies all observations; any remedial recommendations are separately discussed and quoted.
Can you rewire a home while it is occupied?
Room-by-room rewires in occupied homes are possible, though the timeline and access arrangements need to be planned carefully. We discuss occupancy, access constraints and likely disruption at the survey stage before confirming a programme.
What is included in a consumer unit upgrade?
A consumer unit replacement typically involves removing the existing fuseboard, installing a modern unit with appropriate RCD or RCBO protection, reconnecting the circuits, testing the installation and issuing the relevant completion certificate. The exact scope depends on what is already in place; we assess this before quoting.
Can residential electrical work be co-ordinated with other ComGas home services?
Yes. The residential electrical team works alongside our gas, heating and plumbing teams. Where electrical and heating or plumbing work is happening at the same property, we can co-ordinate access and scheduling so you are not managing separate contractors.
Planning home electrical work or need an electrical safety check?
Tell us about the property, what you need and any access or occupancy constraints. The team can advise on the right approach and arrange a survey where appropriate.
