ComGas installs, tests and certifies emergency lighting systems for offices, schools, care settings and other commercial premises across Surrey and surrounding counties, supporting the responsible person's statutory testing duty with monthly checks, annual full-duration tests and clear records.
Emergency lighting is a statutory duty, not an optional extra
The system only proves itself on the one day it is actually needed.
Emergency lighting exists to light escape routes, open areas and high-risk tasks if the normal supply fails, giving people enough time and visibility to leave a building safely. It sits alongside general electrical services but is tested and maintained on its own regime, because a luminaire that looks fine when the mains is on tells you nothing about whether its battery will hold a useful charge in the dark. Under the Regulatory Reform (Fire Safety) Order 2005, the duty to ensure emergency lighting is provided and maintained sits with the responsible person for the premises — not with any contractor carrying out the work.
Where testing lapses, where a layout changes without the lighting design being reviewed, or where batteries are simply left to age past their useful life, the shortfall is usually invisible until a power failure exposes it. A luminaire can pass a brief monthly check and still fail to hold its charge for the full duration required, and coverage gaps that were acceptable under an old floor plan can become genuine blind spots once partitions, storage or furniture change how a space is used.
ComGas installs, tests and certifies emergency lighting to BS 5266-1 and BS EN 50172 for commercial buildings across Surrey, Hampshire and Berkshire, working to the escape route drawings and helping the responsible person keep a defensible record of what has been checked, when, and with what result.

How we approach emergency lighting testing and installation
Survey the escape routes, test to schedule, record every result, then remedy and certify.
Before any new installation, we survey the building against its actual escape routes rather than assuming an existing layout is still correct — plans get updated, but the lighting design attached to them does not always keep pace. Where we are testing an existing system, we work to the monthly and annual regime set out in BS EN 50172, checking function and, on the annual visit, that each luminaire achieves its full rated duration rather than only lighting briefly.
Every result is recorded against the individual luminaire, so a pattern of failure in one part of a building is visible rather than lost in a single pass/fail summary. Findings are explained in plain terms and prioritised — a failed luminaire on a primary escape route is not the same priority as a minor gap in a rarely used store — before any remedial work is agreed and, on completion, certified.

What we consider before any emergency lighting work
Layout changes, occupied buildings and battery age all affect what a system actually needs.
Emergency lighting installed correctly for one floor plan can leave gaps once partitions move, storage is added or a room changes use, so we check the design against the building as it is now, not as it was originally drawn. Annual full-duration testing typically discharges batteries for around three hours, which needs to be timed and communicated so the building is not left without emergency cover during an incident that coincides with the test window. Battery age, access to high-level fittings, and whether spares are still available for older equipment all shape whether a repair or a replacement is the sensible option.
Layout and use changes checked against the original lighting design
Full-duration testing timed to avoid leaving occupied areas unprotected
Battery age and remaining service life assessed, not assumed
Access arrangements confirmed for high-level or restricted fittings
Availability of spares checked before repairing obsolete equipment
Coordination with other planned electrical or fit-out works
Every emergency lighting scope is based on the building's actual escape routes and current layout. We do not apply a standard specification without first confirming it still matches how the space is used.
Who we work with
Emergency lighting installed and tested for buildings where evacuation planning matters most.

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!

I had an issue with my boiler and Matt came out to have a look the same day and managed to fix it. Great, professional service. Highly recommend.

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.

Lovely engineers, Matt and Jack, were a pleasure to have in the house. Thorough, knowledgeable, tidy and polite. Would highly recommend.
Emergency lighting FAQs
Questions about emergency lighting testing, certification and installation
Common questions about the testing regime, who holds the duty, and how this service relates to other electrical work.
Who is legally responsible for emergency lighting testing?
The duty sits with the responsible person for the premises under the Regulatory Reform (Fire Safety) Order 2005, not with the contractor carrying out the work. We support that duty with testing, certification and logbook records, but we cannot take on the legal responsibility itself — that stays with the building's responsible person.
Does an EICR cover emergency lighting testing?
No. An electrical installation condition report assesses the fixed electrical installation and is carried out on a different cycle. It does not discharge the monthly and annual emergency lighting testing duty, which is a separate regime under BS EN 50172 and needs to continue in addition to any EICR.
What is the difference between monthly and annual testing?
The monthly test is a brief function check confirming each luminaire operates on loss of mains supply. The annual test is a full-duration test, typically three hours, confirming the battery can actually sustain the required illumination for that period rather than just switching on briefly.
Is this the same as your LED lighting upgrade service?
Not usually. General relighting and LED replacement is covered by our LED lighting upgrades service and addresses everyday illumination rather than statutory emergency cover. The two are often carried out together on a refurbishment, but emergency lighting is scoped and tested as its own system.
Why did our emergency lighting fail its full-duration test?
Common causes include a battery that has aged past its useful life, a luminaire that was never correctly matched to its lamp load, or general component wear. We identify the specific cause for each failed luminaire rather than replacing equipment on a blanket basis.
Do you provide logbooks and certification?
Yes. We issue certification on completion of installation or testing work and keep logbook entries current, so the responsible person has an accessible, defensible record to show what has been tested, when, and with what result.
Overdue on testing, or reviewing coverage after a layout change?
Tell us about the building, the current state of your testing records, and any areas you know have changed since the system was last reviewed. We can advise on the right approach and arrange a survey where appropriate.
