ComGas provides planned and reactive electrical maintenance for offices, schools, care settings and other commercial buildings, keeping installations safe, compliant and running reliably across Surrey and surrounding counties.
Commercial electrical installations degrade gradually — connections loosen, insulation ages, protective devices drift out of tolerance — long before any of it is visible as a fault. Most of what causes an unplanned electrical failure has already shown a sign of it on the previous inspection, if someone was looking for it. This is what a maintenance programme is actually for: not simply confirming an installation still works, but catching the early indicators of what will eventually stop it working.
Left unmanaged, that degradation shows up at the worst time — an out-of-hours trip, a failed circuit mid-lesson, a distribution board that has been running hot for months before anyone notices. The cost of a reactive-only approach is rarely the repair itself; it is the disruption, the lost use of a space, and the fact that the same fault would have been a minor remedial item on a scheduled visit six months earlier.
ComGas delivers planned and reactive electrical maintenance for commercial buildings across Surrey, Hampshire and Berkshire, structured around a defined asset list and a schedule agreed with the building rather than a generic annual visit.

Commercial electrical maintenance from Farnham, Surrey.
Four ways we keep an electrical installation maintained, compliant and understood.
Scheduled inspection and testing against a defined asset list, agreed around how the building actually operates.
Attendance to electrical faults identified between planned visits, diagnosed properly rather than patched.
Corrective works arising from inspection findings, quoted and sequenced by risk rather than treated as one undifferentiated list.
Test records, certification and an audit trail that supports statutory duty and demonstrates ongoing management.
Planned. Professional. Practical.
We start by agreeing a visit schedule around how the building is actually used — term dates for a school, occupied hours for an office, resident routines for a care setting — rather than fitting the building around a standard visit pattern. Each visit works against a defined asset list specific to that building, so what gets inspected is consistent from one visit to the next and nothing is missed because it wasn't on anyone's list.
Findings are prioritised by risk rather than raised as a flat list: a loose connection on a heavily loaded circuit is treated differently to a cosmetic item on a rarely used spur. Remedial works are quoted and sequenced accordingly, and records are issued after every visit so there is a clear, dated history of what was found, what was done, and what remains outstanding.
Electrical maintenance in a working building is rarely straightforward. Isolations have to be planned around what each circuit actually serves, out-of-hours access is often needed to avoid disruption, and older installations frequently carry undocumented modifications that only become apparent during inspection. We consider all of this before agreeing a schedule, and we keep the records that let you demonstrate, not just assume, that the installation is being managed properly.
Every maintenance programme is built around the building it serves. We agree the asset list, the schedule and the reporting format with you rather than applying a standard visit regardless of what the installation actually needs.

Electrical containment and wiring were adjusted, then reinstated to full working order alongside the heating, water and alarm systems.

A new distribution board gave the plant room its own renewed electrical supply for the boilers, pumps and controls.

Common questions about how a maintenance programme works and how it relates to inspection and installation work.
Talk to the electrical maintenance teamNo. An EICR is a periodic statutory inspection carried out at a set interval to assess the condition of a fixed installation. Electrical maintenance is the ongoing planned and reactive programme that sits around it — inspecting more frequently against a defined asset list, catching issues between EICRs, and acting on the findings an EICR identifies.
No. Commercial electrical installation is project-based work — new circuits, rewires, or fit-out — delivered as a defined scheme with a start and finish. Maintenance is the continuing programme that keeps an existing installation safe and compliant once it is in service, and remedial installation work identified through maintenance is scoped and quoted separately.
Yes. Electrical maintenance sits naturally alongside mechanical planned preventative maintenance on a single contract, with one contractor, one schedule and one set of records, rather than managing two suppliers with separate visit patterns. See our wider service and maintenance offer for how this fits together.
Serious or high-risk findings are flagged immediately rather than held until a written report is issued, so you can make an informed decision about isolation or urgent remedial action straight away. Lower-risk items are recorded, prioritised and quoted in the normal way.
Yes. Remedial works are certified to BS 7671 / 18th Edition on completion by qualified engineers, and this certification is issued alongside the visit records so your compliance file stays current between formal inspections.
Yes. We start with a survey against a defined asset list to establish the actual condition of the installation, agree what needs addressing first, and build the ongoing schedule from that baseline rather than assuming the previous maintenance history is complete or accurate.
Tell us about the building, the current maintenance arrangement if you have one, and any known issues or upcoming compliance deadlines. We can advise on the right programme and arrange a survey where appropriate.
