Emergency Lighting Installation Costs: Per-Fitting and Per-Building Pricing
By the DC Fire & Security engineering team — installing and maintaining fire and security systems since 2010. Updated June 2026.
Quick answer
Emergency lighting installs at £80–£150 per fitting (LED units, typical wiring) — small premises systems (6–12 fittings with exit signage) land £500–£1,500; larger buildings price per the BS 5266 design that determines fitting counts. Conversions of legacy fluorescent stock to LED typically pay back through battery/lamp maintenance savings within 3–5 years.
What drives the fitting count (and thus the price)
- BS 5266 design logic: escape routes (1 lux minimum along centrelines), open areas over 60m² (0.5 lux anti-panic), and high-risk task areas — plus the mandatory points (exits, direction changes, stairs, fire equipment, call points, plant rooms; the emergency lighting guide's placement canon)
- Exit signage: maintained exit boxes/legends per sight-line design — every escape route legible (the signage layer priced with the lighting)
- Fitting types: non-maintained LED bulkheads (the workhorse — emergency-only operation), maintained units where occupancy demands (entertainment/dark venues), twin-spots for volume spaces, recessed designs for finished ceilings
- Self-test options: +£20–£50/fitting buying automated monthly function tests (the testing-labour trade-off — increasingly default on new installs per the testing guide's economics)
- Wiring reality: dedicated circuits with test facilities (key switches per the testing how-to) — refit contexts cable-share sensibly; new circuits add electrician-day economics
- Central battery alternatives at estate scale (hotels/institutional) — different architecture, engineered pricing
Worked pricing by building type
Design-first sequencing protects budgets: a BS 5266 layout (we produce them) prevents both under-provision (enforcement findings per the requirements guide) and the over-spray of fittings-by-guesswork quotes.
| Premises | Typical scope | Installed cost |
|---|---|---|
| Small shop/office | 6-10 fittings + 2-4 exit signs | £500–£1,200 |
| Restaurant/licensed | 10-18 fittings, maintained mix | £1,000–£2,200 |
| Small HMO/block common parts | 8-15 fittings per core | £700–£1,800 |
| Office floor (open plan + cores) | 15-30 fittings | £1,500–£3,500 |
| School/care block | Per design — corridors, halls, plant | £2,500–£8,000+ |
| LED conversion per fitting | Like-for-like swap | £60–£120 |
Conversions, compliance and commissioning
The LED conversion case most estates face: legacy 8W fluorescent units consuming batteries (£15–£40 each, 4-yearly per the testing guide's failure stats) and lamps convert to sealed LED at £60–£120/fitting — maintenance arithmetic typically repaying within 3–5 years while duration-test pass rates jump. Compliance completion matters as much as hardware: commissioning certificates to BS 5266, as-installed drawings (the zone-plan analogue for lighting), log books initiated, key switches labelled and demonstrated (the monthly-test enablement from the testing how-to), and integration with the premises' wider testing rhythm (our compliance packages fold lighting tests into the visit calendar). Procurement notes echoing every guide: quotes itemising fitting schedules against a design (not 'emergency lighting throughout'), electrician/fire-systems coordination stated, and certification deliverables named — the emergency lighting guide carries the regulatory frame this pricing serves.
