Emergency Lighting in Holiday Lets: When Do You Need It

A cottage in the Lake District lost power during a kitchen fire last winter. The guests, unfamiliar with the layout, could not find the front door in the dark and ended up trying three wrong doors before getting out through a window. No one died, but the local authority's post-incident review found no emergency lighting anywhere on the escape route, and the host's insurer later argued the fire risk assessment on file did not reflect the property as built. That argument is still being fought over, and it is the kind of argument you do not want to be having.

Why the Fire Safety Order Applies to Your Cottage at All

Plenty of hosts assume fire law is for offices and shops, not a converted barn they let out at weekends. It is not that simple. If you let self-catering accommodation to paying guests, even for a single week a year, the Regulatory Reform (Fire Safety) Order 2005 (RRO 2005) applies to the property for the periods it is let. You become the "responsible person," and since section 156 of the Building Safety Act 2022 came into force on 1 October 2023, you must record your fire risk assessment in writing. There is no small-property or few-employees exemption left. If you have not written yours down, you do not legally have one.

That assessment is where emergency lighting gets decided, not guessed at. A generic checklist bought online will not tell you whether your specific staircase, your specific corridor, or your specific bedroom layout needs it. That is a judgement call the assessment has to make explicitly, and it is one of the areas inspectors and insurers scrutinise hardest after an incident, because "we assumed guests would manage" is not a defence.

The law behind this differs slightly depending on where your property sits. The RRO 2005 covers England and Wales. In Scotland, the equivalent duty comes from Part 3 of the Fire (Scotland) Act 2005 and the Fire Safety (Scotland) Regulations 2006, and Northern Ireland runs its own Fire Safety Regulations (Northern Ireland) 2010. The written assessment duty and the responsible person concept carry across all three, even though the legislation is named differently, so do not assume a Scottish or Northern Irish property is exempt just because it does not sit under the RRO 2005.

What BS 5266 Actually Says

BS 5266-1 is the British Standard code of practice for emergency lighting, and it is the benchmark that fire risk assessors and enforcing officers will measure your property against even though it is guidance rather than a standalone legal duty. It sets out that escape routes need a minimum illuminance of 1 lux along the centre line of the route, and open areas larger than 60 square metres need at least 0.5 lux, so that someone can see well enough to get out safely if the mains supply fails.

The standard also expects emergency lighting to operate for a minimum duration, commonly 1 or 3 hours depending on whether the building would be evacuated immediately or partly relies on staying put, and to come on automatically the moment normal lighting fails. For a small self-catering let this usually means battery-backed bulkhead or exit-sign units above doors and at direction changes, not a full commercial installation. This benchmark is treated as the industry standard right across the UK, regardless of whether your property falls under the RRO 2005, the Scottish regime or the Northern Ireland regulations, so a fire risk assessor anywhere in the country will measure your lighting against the same lux figures.

There are two broad types of unit worth knowing before you buy anything. A "maintained" fitting is lit all the time, mains and battery both feeding the lamp, which suits a light that also does a normal job, such as an illuminated exit sign above a door. A "non-maintained" fitting stays dark until the mains supply fails, then switches on automatically, which suits a bulkhead unit on a landing that would otherwise just be another light on the wall. Most self-catering properties end up with a mix: maintained signs over final exits, non-maintained bulkheads along corridors and stairs.

Do You Actually Need It, or Will a Torch in the Drawer Do

Here is the test that actually matters: would "borrowed light," meaning daylight through windows or light spilling from an adjoining room, be enough for a stranger to find the way out at 2am in a power cut? In a small single-storey cottage with a short, straight hallway and a window near the door, the honest answer might genuinely be yes, and a fire risk assessment can record that a torch and clear signage are a proportionate control instead of fitted emergency lighting.

That answer changes fast once you add any of the following: a staircase, a corridor with a turn in it, an internal room with no window, more than one storey, or an escape route that passes through a kitchen or utility area where visibility already suffers from smoke first. Large group lets sleeping ten or more raise the stakes further, because more people trying to navigate an unfamiliar building in the dark at once is exactly the scenario emergency lighting exists to prevent. If in doubt, fit it. A handful of battery bulkhead units cost far less than a claim dispute.

Where It Typically Needs to Go

In practice, fire risk assessors look for coverage above final exit doors, at every change of direction along an escape route, on staircases and at the top and bottom of each flight, in any windowless internal room or lobby, and near firefighting equipment or the fire action notice so guests can read it if the power has gone. If your property has a hot tub, sauna or other higher-risk feature in an outbuilding, check the route from that building back to the main exit too.

Barn conversions and other characterful properties often fail on this point specifically because original doorways were narrowed or repositioned during conversion, leaving a genuinely windowless dog-leg corridor that nobody thought to light. If your property has had structural changes, treat the escape route as new rather than assuming the original layout still applies. Our guide to fire safety for barn conversion holiday lets covers this in more depth.

Installing It Without Overspending

A basic self-catering property that genuinely needs emergency lighting is usually looking at somewhere between a handful and a dozen units, and self-adhesive battery bulkheads with a reasonable duration can be fitted by a competent person without rewiring the property, provided your fire risk assessment supports that approach and the units meet BS 5266 performance requirements. Larger or more complex properties, particularly anything wired into the mains lighting circuit rather than running standalone, should use a qualified electrician, not least because the Electrical Safety Standards in the Private Rented Sector (England) Regulations 2020 already require periodic inspection of the property's fixed electrical installation, and any new emergency lighting circuit becomes part of that inspection going forward.

Testing and Keeping Records

Emergency lighting is only useful if it works on the night it is needed, which means it has to be tested, not just installed and forgotten. The usual regime taken from BS 5266 guidance is a brief monthly function test (flick the test key or isolate the supply briefly and confirm the units light up) and a full annual test that runs the batteries for their full rated duration to confirm they hold charge. Keep a simple log of both. If your property is unoccupied between lets, build the monthly check into your changeover routine rather than relying on memory.

These records matter beyond good practice. If there is ever a fire, an insurance claim, or a complaint to the local council, the written fire risk assessment together with your testing log is what demonstrates you took the RRO 2005 seriously rather than treating it as paperwork nobody reads. Missing records do not prove you had no lighting, but they remove your best evidence that you did, and that gap tends to get resolved against the host, not for them.
