How to Quote and Run a Commercial Emergency Lighting Installation

What you will learn

• Why a luminaire schedule built from a site survey is the only reliable basis for an emergency lighting price.
• How BS 5266-1:2025 determines which areas need coverage, at what lux levels, and for how long.
• How to separate materials, labour, testing, and certification into distinct quoted line items.
• How to programme installation in occupied premises without leaving escape routes unlit at any stage.
• What the commissioning test must confirm before you can issue the installation certificate.
• How to convert the installation handover into an ongoing maintenance contract with higher take-up rates.

Commercial emergency lighting is a compliance-driven installation type where the quote that wins the job and the documentation that closes it carry equal weight. Most commercial and non-domestic buildings in the UK are required to install emergency lighting under the Regulatory Reform (Fire Safety) Order 2005, and to test and certify it against BS 5266-1:2025, the current British Standard published by BSI. For electrical contractors taking on this work, the margin risk is not in the fitting - it is in underpricing the site survey, skipping the luminaire schedule, and handing over a job without the correct certification. This guide covers how to price, run, and close an emergency lighting installation from first site visit to signed certificate.

What Makes an Emergency Lighting Installation Different

Emergency lighting is a life-safety system, and that distinction shapes every stage of the job. The governing standard is BS 5266-1:2025, enforced through the Regulatory Reform (Fire Safety) Order 2005. The responsible person at any commercial premises - typically the business owner, building manager, or facilities manager - is legally required to ensure emergency lighting is installed, tested, and maintained to specification.

For contractors, this means that virtually every commercial premises where staff or visitors are present requires emergency lighting: offices, retail units, warehouses, schools, healthcare facilities, and hospitality venues are all within scope. The work also clusters around trigger events - a building reconfiguration, a change of occupancy, a fire risk assessment that identifies non-compliance. Each trigger creates an installation contract, often followed by a testing and maintenance relationship.

Three types of area require coverage under the standard. Escape routes - corridors, staircases, fire exits - require at least 1 lux at floor level. Open areas where occupants might be in darkness require 0.5 lux. High-risk task areas, where people may be operating dangerous equipment, require 15 lux or 10% of normal lighting levels. Fire safety equipment locations need 5 lux measured vertically. Fitting at the wrong level in any zone is a documented defect, which means the certificate cannot be issued until it is remediated.

The minimum rated duration for most commercial buildings is three hours. One-hour systems are only permitted where immediate evacuation is guaranteed and reoccupation is prohibited until batteries recharge - in practice, most insurers and fire authority auditors expect three-hour systems in commercial environments.

Site Survey and the Luminaire Schedule

No accurate quote exists without a site survey. Emergency lighting pricing is driven by fitting count, fitting position, cable route length, and access conditions - none of which you can establish from an address or a set of drawings alone. Before you commit to a price, walk the building with the fire risk assessment in hand (if one exists), identify every escape route and protected zone, map the cable routes between fitting positions, and produce a count of the luminaires the design requires.

The output of the survey is the luminaire schedule: a document listing every emergency fitting required, its type, its location, and the circuit it connects to. The key type distinction is maintained versus non-maintained. A maintained fitting is illuminated continuously and switches to battery power on mains failure - most exit signage uses this type. A non-maintained fitting activates only during a power failure - most corridor bulkheads and open-area fittings use this type. Getting the schedule wrong means specifying the wrong product, ordering the wrong materials, and issuing a certificate against a non-compliant installation.

The survey also reveals what the building actually allows in terms of installation method. An occupied office building with a live ceiling grid requires phased access and possibly out-of-hours installation. A warehouse with clear cable tray runs presents very differently. Both factors shape your labour estimate significantly, and neither shows up on a PDF floor plan.

Quoting the Job

An emergency lighting quote should present four cost elements separately. A single total figure gives the client no visibility of what they are paying for, and gives you no basis on which to claim if any element overruns.

Materials. The luminaire schedule drives your materials list directly. Price self-contained LED emergency fittings as the standard choice - modern LED emergency luminaires are significantly more energy-efficient than older fluorescent types and carry a longer rated life that matters for the maintenance cost the client will face over the system's life. Where the building requires a central battery system rather than self-contained units - a less common but valid specification for large open-plan or healthcare environments - price the battery cabinet, monitoring panel, and additional wiring infrastructure as explicit line items.

Installation labour. Price cable routes by metre, not by fitting count. The containment and cabling work is the largest labour variable on most emergency lighting jobs, particularly in occupied or listed buildings where surface containment is not acceptable. Out-of-hours or phased-access installation carries a distinct labour rate that should appear in the quote, not be absorbed as a contingency. A clear scope of works prevents the argument about what "installation" included when the cable route through the plant room takes four hours longer than planned.

Testing and initial certification. The commissioning test is a priced item, not a task at the end of the job. After installation, you must carry out a full-rated duration test before you can issue the installation certificate. For most commercial buildings, that means three hours with the mains isolated, confirming every luminaire holds specification. Price this as a separate visit if the scale of the installation warrants it. If testing identifies defects, remediation is additional scope.

Handover documentation. The client needs a completed log book, the installation certificate, and the luminaire schedule as a record document. If you are also tendering for the ongoing maintenance, the log book setup is the start of that relationship. Document preparation takes real time on a large installation - price it.

Running the Installation

Agree the programme before the first van arrives on site. Emergency lighting installation in an occupied building requires more programme discipline than most electrical work because you cannot leave any escape route unlit while the job is in progress. If the building has three floors, complete each floor in full before moving to the next. If the work is out of hours, confirm access arrangements in writing with the facilities manager, not just in a phone call.

The installation sequence for each section runs: cable containment first, then luminaire mounting and wiring, then circuit connection, then a short functional test on that section before moving on. This prevents partially-wired circuits from being left active over a weekend or between visits, which is both a compliance risk and a fire safety issue.

Where the installation sits inside a larger fit-out - a new office floor, a building refurbishment, a change of occupancy - you are working alongside other trades. Emergency lighting typically follows the first-fix electrical programme but must be complete before ceiling completion and decoration. Get ceiling access closure dates from the main contractor in writing before your programme starts, and ensure your luminaire positions are marked on the ceiling grid before that access is lost.

Record every fitting installed against the luminaire schedule as you go. If any fitting position changes because of a structural obstruction, a revised escape route, or a layout change, that is a variation. Capture it in writing before the commissioning test. A certificate issued against a luminaire schedule that does not match the as-installed layout is non-compliant, and the job remains open until the discrepancy is resolved.

Testing, Certification, and Handover

The commissioning test is where the installation proves its compliance. Under BS 5266-1:2025, the test procedure proceeds in sequence:

1. Isolate mains supply to the emergency lighting circuit and confirm all luminaires and exit signs activate correctly.
2. Allow the system to run for its full rated duration - three hours for most commercial installations - without any fitting failing or dropping below specified lux levels.
3. Restore mains power and confirm the system enters recharge mode correctly on all circuits.
4. Record the results against each fitting on the luminaire schedule, noting any failures or deficiencies.
5. Complete the installation certificate against the test record. Where defects were identified and remediated before the test, record those repairs.
6. Set up the maintenance log book with the installation date, fitting count, test type completed, and first monthly test due date.
7. Hand over the certificate, log book, and luminaire schedule to the responsible person or facilities manager, and confirm their ongoing obligations.

The certificate is not the last page of the job - it is the start of the compliance trail the client must maintain. Monthly functional tests are required every calendar month under BS 5266-1:2025. These are short checks - mains supply is briefly interrupted and each fitting confirmed to activate - and they can be carried out by a trained responsible person on site, with results recorded in the log book. The annual full-duration test, and the five-year photometric verification introduced in the 2025 edition of the standard, require a competent contractor.

For digital field forms, test records, and certificate generation, building these into a standardized workflow through eForms eliminates the logbook gap that causes compliance failures at fire authority inspection - and removes the administrative backlog that prevents same-day certificate issue.

Maintenance Contracts and Follow-On Work

The installation job creates a repeat revenue opportunity that most electrical contractors convert too slowly. Once you have installed the system, you know the fitting count, the cable layout, the test history, and when battery replacements will be needed. You are the most efficient contractor to provide the annual maintenance contract, and the most credible - because you have the original certificate.

A maintenance contract scoped at handover should cover two elements: the annual full-duration test (with logbook update and certificate issue) and a remedial allowance for battery and fitting failures. Battery life in self-contained LED emergency fittings is typically three to five years depending on test frequency and environmental conditions. A system installed in 2026 will start generating battery replacement requirements before 2031. Pricing this into a multi-year maintenance contract protects your margin and the client's compliance calendar.

Quoting the maintenance contract at the point of handover - not six months later when the client has started looking elsewhere - significantly improves take-up. A one-page proposal covering the annual test schedule, the response commitment for reactive callouts, and the annual fee is enough to convert the majority of installation customers into recurring clients at a moment when they are in a compliance mindset and have just seen you deliver the installation correctly.

See the related guide on fire alarm and detection installation for how a sister life-safety system is quoted and run - many contractors bid both systems on the same premises, which reduces programme coordination costs and strengthens the maintenance contract offer.

Closing

Emergency lighting installation sits at the intersection of electrical work and fire safety compliance, and the contractors who understand both build the most defensible positions in this market. Quoting it correctly means surveying before pricing, separating materials from certification as distinct line items, and handing over documentation that actually functions as a compliance record. Running it correctly means a programme that never leaves escape routes unlit and a commissioning test that matches the luminaire schedule exactly. Done well, the installation certificate is not the end of the job - it is the opening of a maintenance relationship the client cannot walk away from without starting the compliance process again.
