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 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.

Emergency lighting installation and testing from Farnham, Surrey.
We survey existing coverage against the escape routes before recommending any installation or remedial work.
New emergency lighting installation and extensions to cover layout changes, refurbishments or previously uncovered areas.
Routine brief function tests and the annual full-duration test, carried out to the BS EN 50172 regime.
Certification issued on completion of installation or testing, and logbooks maintained so the responsible person has a defensible record.
Repair and upgrade of existing systems where testing identifies failed batteries, coverage gaps or obsolete fittings.
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.
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.
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.

Common questions about the testing regime, who holds the duty, and how this service relates to other electrical work.
Talk to the emergency lighting teamThe 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.
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.
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.
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.
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.
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.
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.
