Commercial Service
Emergency Lighting
Compliant emergency lighting design, installation and servicing for commercial premises — from initial system design through to monthly testing records, annual certification and addressed DALI integration.
What a compliant emergency lighting system actually has to solve
01
A system installed years ago with no audit trail
Older non-addressable systems leave no verifiable record of which luminaires were tested and when. We carry out a full condition survey and deliver a documented baseline before recommending any remedial or replacement works.
02
Monthly test records that don't satisfy your insurer
Functional tests and annual duration tests must be documented to satisfy BS EN 50172, Fire Risk Assessment requirements and insurers. We put in place a maintained test schedule and provide digital records in a format you can evidence immediately.
03
No clear route to BS 5266 compliance
The standard covers escape route illuminance, open-area lighting and high-risk task area lighting — each with its own maintained lux requirements. Our design service begins with an exit route and zone plan, ensuring the installed system meets all three categories.
04
Disruption during occupied hours
Emergency lighting works typically have to happen around occupancy. We phase commissioning and test cycles outside business hours and keep the building certificated at every stage so there is no gap in your compliance record.

The Numbers
3hr
Annual 3-hour duration tests are required under BS EN 50172 — we carry out, witness and certify every test.
1lux
BS EN 50172 minimum along the centre line of an escape route — our designs are calculated to meet and exceed this at every point.
5yr
Typical rated service life for central battery systems specified to EN 50171, with battery replacement programmes built into our maintenance plans.
Why specify Con-Tec
Compliant from Day One
Our Emergency Lighting Approach
01
Survey & Condition Report
We survey the existing installation and existing documentation, producing a written condition report and gap analysis against BS EN 50172 and BS 5266.
02
Design & Specification
A photometric design and luminaire schedule is produced before any equipment is ordered, with lux calculations at each escape route zone submitted for your approval.
03
Installation & Commissioning
Works phased around occupancy by directly-employed NICEIC engineers, with the building certificated at each handover milestone.
04
Ongoing Maintenance & Testing
Monthly function tests, annual duration tests and a digital record system — all included in a fixed-price maintenance agreement.
