Emergency lighting certificates and BS 5266: what needs one, and what doesn't
BS 5266-1 requires emergency lighting certificates for commercial and industrial premises, the common areas of flats, HMOs and care homes, but not for an individual home, which is outside its scope. A certificate is issued when the system is commissioned and again at each periodic inspection.

The short answer
BS 5266-1:2025 sets out emergency lighting requirements for commercial premises, industrial premises, common areas of blocks of flats, HMOs, care homes and sheltered housing. It explicitly does not apply to an individual domestic dwelling — a private house, or a self-contained flat’s own interior, is outside its scope. Where it does apply, a certificate is produced when a system is first commissioned, and again at each periodic inspection to confirm it remains compliant.
Where BS 5266-1 applies — and the domestic exclusion
BS 5266-1:2025 sets out emergency lighting requirements for commercial and industrial premises: offices, shops, factories, warehouses and similar non-domestic buildings. It also applies to residential settings that function as shared or managed accommodation — common areas of blocks of flats (corridors, stairwells, communal lobbies), HMOs, care homes and sheltered housing.
BS 5266-1 explicitly does not apply to an individual domestic dwelling. A private house, or the self-contained interior of a single flat, is outside its scope — that is the regulation, not a gap in coverage. A homeowner does not need a BS 5266-1 emergency lighting certificate for their own house.
Blocks of flats — the same split as fire alarms
The same domestic/non-domestic split used for fire alarm certification applies here: the common parts of a block of flats — corridors, stairwells, communal entrance areas — are assessed under BS 5266-1, because those spaces are shared, managed space rather than a private dwelling. The interior of an individual flat is not.
Commissioning and periodic inspection
A BS 5266-1 certificate is produced when an emergency lighting system is first commissioned, confirming the installation was designed, installed and tested to the standard. The system then needs periodic inspection and testing to confirm it remains compliant and each fitting still performs as designed — the exact servicing and testing regime is set out in the guidance that accompanies BS 5266-1 and by the system manufacturer.
Where an existing system is being re-inspected rather than newly commissioned, the certificate records the current condition of the installation — similar in principle to how an EICR records the condition of a fixed electrical installation rather than certifying new work.
Competence — BS 5266 assessment, not a fixed qualification
As with other specialist certificate types, there is no single mandatory qualification that entitles someone to sign a BS 5266-1 certificate — competence assessed against BS 5266 is the industry’s reference point, in the same way competent-person scheme membership is the practical proxy for BS 7671 work.
Frequently asked questions
- Does my house need an emergency lighting certificate?
- No. BS 5266-1 explicitly excludes individual domestic dwellings — it does not apply to a private house or the interior of a single self-contained flat.
- What buildings does BS 5266-1 apply to?
- Commercial and industrial premises, plus residential settings that function as shared or managed accommodation: common areas of blocks of flats, HMOs, care homes and sheltered housing.
- Do the common areas of my block of flats need emergency lighting testing?
- Likely yes — corridors, stairwells and communal entrance areas in a block of flats are typically assessed under BS 5266-1, even though the interior of each individual flat is not.
- What’s the difference between a commissioning certificate and a periodic inspection certificate?
- A commissioning certificate confirms a newly installed system was designed, installed and tested to BS 5266-1. A periodic inspection certificate is issued later, confirming an existing system is still performing as designed — the emergency lighting equivalent of an EICR checking an installation’s ongoing condition.
- Is a specific qualification legally required to sign a BS 5266-1 certificate?
- No single qualification is mandated by law. Competence assessed against BS 5266 is the industry’s practical reference point, similar to how competent-person scheme membership works for general electrical work — the person signing is responsible for their own competence.
- Does a care home or HMO count as domestic for BS 5266-1 purposes?
- No — care homes, HMOs and sheltered housing are explicitly within scope of BS 5266-1, even though they are residential in nature, because they are shared or managed accommodation rather than a single private dwelling.
