Short answer: there is no single document called an “emergency lighting certificate”. What a fire officer, a licensing officer or an insurer actually wants to see is three things: a completion certificate from when the system was installed and commissioned, a periodic inspection and test certificate from the last annual full-duration test, and a log book showing the monthly function tests in between. In London in 2026, expect from £180 labour for an annual three-hour discharge test and certificate on a small installation, rising with the number of luminaires. The standard behind all of it changed in October 2025 — BS 5266-1:2025 replaced the 2016 edition and added a five-yearly light-level check that almost nobody has budgeted for.

Is an emergency lighting certificate a legal requirement?
The certificate itself is not named in any Act. The duty to have working emergency escape lighting, and to be able to prove it works, is.
If you run or manage a non-domestic premises — a shop, an office, a takeaway, a warehouse, a nursery, a gym, a barber’s, a railway arch unit — you are the “responsible person” under the Regulatory Reform (Fire Safety) Order 2005. Articles 13, 14 and 17 require emergency routes and exits to be lit where necessary, and require the fire safety equipment to be maintained in efficient working order and in good repair. The same Order covers the common parts of blocks of flats, which is why freeholders and managing agents get asked for the same paperwork even though nobody lives in the stairwell.
If the building is an HMO, the duty comes through the Housing Act 2004 and the licence conditions your borough attaches to it. Haringey, Hackney, Enfield and Waltham Forest all routinely ask for emergency lighting records at licence application and renewal.
If the system was installed as part of a building project, Regulation 38 of the Building Regulations required the fire safety information — including the emergency lighting design, commissioning results and maintenance instructions — to be handed to the responsible person at completion. If nobody handed you a pack, you have a gap, and reconstructing it later costs more than getting it right did.
How you prove compliance is a code of practice: BS 5266-1, with BS EN 1838 for the light levels and BS EN 50172 for the testing regime. A code of practice is not law, but it is what an inspector, an insurer and a court will measure you against, and departing from it is something you have to justify.
What changed in BS 5266-1:2025
BS 5266-1:2025 was published in October 2025 and fully replaced BS 5266-1:2016, which is withdrawn. Most of the day-to-day regime is unchanged — monthly function test, annual full-duration test — but four changes matter if you own or manage a building in London:
- A five-yearly photometric verification. Measured light levels, taken with calibrated equipment, checked against the original design and recorded in the log book. This is new, and on a system installed in 2012 with LED retrofits since, it is the check most likely to fail.
- A limit on how much one fault can take out. A single electrical fault on a centrally supplied circuit must not disable more than 20 luminaires, and higher-risk areas need supplies from two separate circuits. On older buildings where the whole escape route hangs off one sub-circuit, that is a design change, not a test failure.
- Three categories, not one. The standard now deals explicitly with emergency escape lighting, local area (high-risk task) lighting and standby lighting. A kitchen, a plant room or a machine shop may need 15 lux of task lighting, not the 1 lux that gets an escape route signed off.
- Updated references to BS EN 1838:2024 and BS EN 50172:2024, which tightened how levels and uniformity are demonstrated.
None of this means a working system installed under the 2016 edition is suddenly illegal. It means the next annual test should be recorded against the current standard, and that if you are specifying a new system now, a designer still quoting 2016 clauses is behind.
What does an emergency lighting test actually involve?
Two routines, at two different intervals, and they are not interchangeable.
The monthly function test is short and deliberately shallow. Every calendar month, each luminaire and exit sign is put into emergency mode — by key switch, test switch or an addressable panel — for long enough to confirm the lamp lights and the fitting changes over. Then it is restored, and the result is written in the log book. The point is to catch a dead lamp or a failed inverter early. It does not discharge the battery and it takes minutes, not hours. You can do this yourself. A competent member of staff with the log book and a test key is exactly who BS EN 50172 has in mind, and paying an electrician monthly to flick switches is money wasted.
The annual test is the one that needs an electrician. The mains supply to the emergency luminaires is isolated and every fitting has to stay lit for its full rated duration — normally three hours. At the end of it, light levels along the escape route are still expected to be adequate, the batteries are put back on charge, and the recharge period (up to 24 hours) is noted. Any fitting that dies at two hours forty has failed, even though it lit up fine at the start. That is the whole reason the annual test exists: batteries degrade quietly, and a monthly flick test will never find it.
Because the building is effectively without emergency lighting until the batteries recover, the annual test is planned for a low-risk time — the start of a quiet day, a closure, out of hours. On premises with sleeping accommodation that planning is not optional.
Then the paperwork: a periodic inspection and test certificate recording the date, the duration achieved, every luminaire tested, every fault found, and what was done about it. That is the document people mean when they say “emergency lighting certificate”.
Emergency lighting certificate cost — London 2026
All prices below are labour only and include VAT. Replacement fittings, batteries, exit signs and cable are charged separately at cost, and we tell you what they are before we order. Our minimum charge is one hour at £90 plus VAT — £108 inc VAT, so nothing here is priced below that, however small the job.
You will see £59 and £69 headline prices advertised for emergency lighting certificates in London. Ask what they cover. At those figures nobody is standing in your building for three hours waiting for the last fitting to drop out, and a certificate issued without a full-duration discharge is a certificate for a test that did not happen.
| Job | What it covers | Price (labour only, inc VAT) |
|---|---|---|
| Annual duration test and certificate — up to 10 luminaires | Full three-hour discharge, every fitting and exit sign checked, periodic inspection and test certificate, log book written up. A flat above a shop, a small office, a single-stair HMO | from £180 |
| Annual test and certificate — 11 to 25 luminaires | As above. A shop with a rear escape, a converted house in multiple occupation, a small industrial unit | from £240 |
| Annual test and certificate — 26 to 50 luminaires | As above, usually a half day on site plus a return to confirm recharge | from £330 |
| Annual test — over 50 luminaires, or several blocks | Priced per luminaire from £7, with a £330 minimum per visit. One certificate per building or per landlord’s supply | from £7 per fitting |
| Monthly function test, carried out for you | If you would rather not do it in-house. One hour, log book completed and signed. Worth combining with another visit | from £108 |
| Five-yearly photometric light-level verification | New under BS 5266-1:2025. Calibrated readings along the escape route and at high-risk task areas, compared against the design, recorded for the log book | from £300 |
| Commissioning and completion certificate for a new system | Initial verification, first full-duration test, as-installed drawing, log book issued and the Regulation 38 information pack | from £240 |
| Replacing a failed emergency luminaire or exit sign | Like-for-like swap on an existing point, tested and logged. Per fitting, with the £108 minimum applying to the visit | from £90 per fitting |
| Battery or converter pack replacement | Where the fitting is sound and accessible. Per fitting, £108 minimum visit | from £60 per fitting |
| New emergency escape lighting to an HMO staircase | Typically four to six three-hour self-contained fittings and a signed exit, on a permanently live supply from the landlord’s board, with a completion certificate | from £600 |
| New emergency lighting to a shop or small commercial unit | Sales floor, rear store, escape corridor and exit signage, designed to BS EN 1838 levels rather than guessed at | from £780 |
| Reconstructing missing records | Where there is no log book and no history — survey, schedule every fitting, one full-duration test to establish a baseline, new log book | from £240 |
If the annual test throws up remedial work, we itemise it and you are free to have someone else do it. Where the root cause turns out to be the board rather than the fittings — no permanently live way of feeding the emergency circuit, no spare way at all — see fuse board replacement, which starts from £550.
Does my building need emergency lighting at all?
This is the question worth asking before you pay for a test, because a surprising number of small London landlords are being sold emergency lighting they do not need, and a smaller number are missing it where it genuinely matters.
For non-domestic premises, the fire risk assessment decides. In practice, almost any commercial unit where people would have to find their way out in the dark needs it: a basement, a windowless rear store, an internal corridor, a railway arch. A single-room shop with a glazed front door onto a lit high street may not.
For HMOs and converted flats, the LACORS housing fire safety guidance is what councils work from, and it scales with storeys:
- Up to two storeys — conventional lighting is usually adequate. A two-storey shared house off Lordship Lane with a window on the landing does not need emergency lighting, and you should push back if you are told it does.
- Three to four storeys — it may be appropriate where the escape route is long or complex, or where there is no effective borrowed light. That last phrase is what decides most Victorian conversions in Haringey and Hackney: a staircase with a glazed front door and a landing window borrows enough light; a back-of-plan stair boxed in by later partitioning borrows none.
- Five to six storeys — expect it to be required, and for bedsit-type HMOs and converted flats at that height, treat it as a given.
Those figures assume normal risk and that the rest of the fire precautions are in order. If your licence condition says fit it, fit it — arguing LACORS with a licensing officer is not a winning strategy — but do ask for the condition in writing so you know what you are pricing.
A single-family house let on an assured shorthold tenancy needs a satisfactory EICR and working smoke alarms. It does not need emergency lighting.
Emergency lighting is not part of the EICR
This catches people out constantly, so it is worth being blunt. An EICR is an inspection and test of the fixed electrical installation to BS 7671. It will confirm that the circuit feeding your emergency lighting is safe. It will not discharge the batteries, will not measure light levels on the escape route, and will not produce a BS 5266 certificate. Four separate regimes, four separate records:
| Regime | Standard | Interval | Record |
|---|---|---|---|
| Fixed wiring | BS 7671 | Up to 5 years domestic let, commonly 3–5 years commercial | EICR |
| Emergency lighting | BS 5266-1:2025 | Monthly function, annual duration, 5-yearly photometric | Completion certificate, periodic inspection and test certificate, log book |
| Fire detection and alarm | BS 5839 | Weekly user test, service at least every 6 months | Service and commissioning records |
| Portable appliances | IET Code of Practice | Risk-based | PAT register |
If you want the difference between the first and the last spelled out, we have written it up separately: EICR vs PAT testing. And if you are collecting the whole set for a licence application, the landlord electrical compliance checklist lists what councils ask for.
What actually fails on North London emergency lighting
Nine faults account for most of what we find, and only two of them are dead batteries.
The emergency fittings are wired downstream of a switch or a timeclock. The single most common real fault on the shop parades — Tottenham High Road, Green Lanes, Kingsland Road, Fore Street. The emergency lighting on the shared rear stair was spurred off the shop’s lighting circuit, so when the shop switches off at night the fittings lose their permanent live and the batteries never charge. Everything looks fine at four in the afternoon. At midnight the stair has nothing. Emergency luminaires need an unswitched permanent supply, and on a shop with flats above that supply should come from the landlord’s board, not the tenant’s.
One-hour fittings in sleeping accommodation. Three hours is the duration for premises where people sleep, for phased evacuation and for entertainment venues. One hour is only acceptable where evacuation is immediate and the building is kept empty until the batteries recharge — which describes very few HMOs. We find one-hour fittings in three-storey conversions regularly, usually because someone bought what was on the shelf.
No test facility. No key switch, no local test switch, no panel — so the only way to run a test is to pull the MCB. Half the time that MCB also feeds the fire alarm, or the landlord’s stair lighting, and the “test” knocks out more than it proves. Retrofitting test switches at the same visit is cheap and pays for itself over a few years of monthly tests.
Charge indicator out and nobody noticed. Every self-contained fitting has a small LED confirming it is charging. Nobody looks at them, because nobody has been told to. This is what the monthly test exists to catch.
More than 20 fittings on one circuit. Now explicitly a design problem under BS 5266-1:2025. Common on older centrally supplied systems in converted offices and small blocks.
Signage that points the wrong way, or no pictogram at all. Text-only “EXIT” boxes and arrows left pointing at a route that was partitioned off years ago. Signage should be to BS EN ISO 7010 and should match the route as it is today, not as it was on the original drawing.
LED retrofits into a designed system. Somebody swapped fluorescent emergency fittings for LED panels because they were brighter and cheaper to run. Brighter is not the test — spacing and uniformity are, and a handful of intense points with dark gaps between them can measure worse on the escape route than the fittings they replaced. This is exactly what the new five-yearly photometric check is aimed at.
Nothing outside the final exit. The escape route is lit all the way to the door, then the yard, the rear alley or the external stair is pitch black. BS 5266 expects the route to be lit to a place of safety, not to the threshold.
No log book. Worth saying plainly: if there is no record, a fire officer will treat the system as untested. A working installation with no paperwork and a dead installation with no paperwork look identical from the outside.
Who needs this most in Haringey, Hackney and Enfield
The pattern across our patch is fairly consistent. Shop parades with flats above are the biggest source of genuinely dangerous findings, for the switched-supply reason above. Licensed HMOs in Haringey, Hackney, Enfield and Waltham Forest are the biggest source of paperwork requests, usually triggered at licence renewal. Railway arches and lock-ups along the Lea Valley and around Hackney Wick have no natural light at all, so escape lighting is essential whatever the floor area — that sits alongside the three-yearly EICR those units usually need.
Office-to-residential conversions inherit an emergency lighting system designed for an office layout — open plan, one route, daytime occupancy — and then get cut up into flats and corridors that the original design never anticipated. The common-parts emergency lighting, its certificate and its log book belong to the freeholder or management company, and they need handing over formally at completion; see office-to-residential conversions. Care homes and supported living are the one setting where nothing about this is negotiable: sleeping accommodation, three-hour duration, and the log book sits in the compliance file next to the EICR. Leaseholders chasing a managing agent for records will find the communal areas guide more use.
For larger commercial sites where emergency lighting is one line in a bigger compliance package, the commercial EICR and commercial electrical costs guides cover the rest.
Frequently asked
How long is an emergency lighting certificate valid for?
Twelve months. The full-duration test is annual, so the certificate from it carries you to the next one — provided the monthly function tests in between are logged. A certificate with a twelve-month date on it and an empty log book behind it does not hold up.
Can I do the monthly test myself?
Yes, and you should. It is a short function check with a test key and a pen, and BS EN 50172 expects the responsible person or a nominated member of staff to do it. We will set the log book up, label the test switches and show whoever is doing it what to look for. The annual full-duration test and the certificate are the parts that need an electrician.
Do you have to shut the building for three hours?
No, but you do have to plan it. The emergency lighting is isolated for three hours and then needs up to 24 hours to recharge, so the building is relying on normal lighting in the meantime. We book it for the start of a quiet day, a closure or out of hours. On premises with sleeping accommodation we will not do it any other way.
My HMO licence says “emergency lighting to be provided”. How many fittings is that?
It depends on the route, not the room count. A typical three-storey converted house with one staircase takes four to six three-hour self-contained fittings plus a signed final exit — from £600 labour. Send us the licence condition and a photo of the stair from each landing and we will tell you what it needs before anyone visits. See also HMO EICRs.
Does an unsatisfactory emergency lighting test get coded C1 or C2?
Neither — those are EICR classification codes and they belong to BS 7671. An emergency lighting test records the fault and whether the system met its rated duration. A fitting that never charges because it is on a switched supply is a genuine safety failure and we say so plainly on the certificate, but it is not a C2.
Does the new five-yearly photometric check apply to my system?
If you are being tested against BS 5266-1:2025 — which is the current edition — then yes, light levels should be verified with calibrated equipment every five years against the original design. If the original design no longer exists, which is common, the first verification establishes the baseline. It is the check most likely to find a problem on a system that has had piecemeal LED replacements.
