Andrew Speake, National Technical Manager at Aico, examines how diverging UK fire safety laws are reshaping domestic protection
How would you summarise the current landscape of domestic fire legislation across England, Scotland, Wales and Northern Ireland?
Fire safety legislation across the UK has evolved over the past decade, but clear differences remain between the four nations. England and Wales rely mainly on Building Regulations (Approved Document B) and the British Standard BS 5839-6, which defines best practice for domestic fire alarm systems. In these countries, the law largely applies to landlords, with homeowners encouraged rather than required to comply.
Scotland has gone further. Its national Tolerable Standard makes interlinked smoke and heat alarms, plus carbon monoxide detection where needed, a legal requirement in every home. Northern Ireland is moving in a similar direction, expanding alarm coverage to bedrooms and mandating interlinking for rented properties.
All four nations share the same safety goals, but Scotland’s universal and enforceable model leads the way. The rest of the UK is progressing more slowly and with less consistency.
Scotland’s approach is often cited as the most stringent in the UK. What are the key differences between Scottish and English legislation, and what lessons could be learned?
Scotland turned best practice into legal obligation. Every home must have interlinked alarms, smoke detection in living rooms and circulation spaces, heat detection in the kitchen, and CO detection where fuel-burning appliances are present.
In England, similar rules apply mainly to rental housing, with no universal standard for owner-occupied homes.
The lesson is simple: clarity drives compliance. When legislation is straightforward and universal, everyone involved understands their responsibility. Scotland’s model has already reduced fire incidents, saved lives, and proven cost-effective for the public.
How do devolved building regulations influence the effectiveness of fire safety compliance across the four nations?
Devolution has been both an advantage and a complication. Each nation can tailor rules to local housing conditions and risks, but this has led to inconsistency.
Scotland and Northern Ireland benefit from clear statutory minimums and stronger enforcement, leading to higher compliance. England and Wales rely more on advisory frameworks, resulting in variable outcomes influenced by local interpretation and resources.
A harmonised baseline across the UK would ensure a consistent level of protection for all households while still allowing regional flexibility.
With a new revision of the British Standard BS 5839-6 expected next year, what major changes or updates do you anticipate?
The next revision of BS 5839-6 is expected to focus on broader alarm coverage and responsiveness to emerging domestic fire risks. The committee may review whether current recommendations should expand to cover more areas of the home, particularly sleeping spaces and open-plan layouts.
Another key focus will likely be on risks linked to lithium-ion batteries, which are increasingly common in homes through e-bikes and energy storage systems. Discussion may also explore how connected technologies, such as IoT-enabled alarms, can enhance reliability and reduce false activations.
This revision offers an opportunity to ensure the Standard reflects modern risks and keeps pace with technological advancement in detection systems.
How well aligned are current building regulations and fire safety standards with emerging fire risks in modern homes, such as open-plan designs and increased use of lithium-ion batteries?
Regulations are playing catch-up. Open-plan living spaces, now a hallmark of modern housing, allow smoke and heat to spread rapidly, making alarm placement more challenging. The traditional “one alarm per storey” rule no longer fits contemporary layouts.
The growing use of lithium-ion batteries introduces a new risk profile. These fires ignite quickly, burn intensely, and produce toxic smoke. Both building regulations and standards will need to evolve to address these realities and better protect households against today’s risks.
Recent figures show that in many domestic fires, smoke doesn’t reach the alarm in time. What installation practices or system designs could better address this problem?
This issue often stems from limited coverage or poor alarm placement. Many homes still rely on detectors in circulation spaces only, meaning fires in bedrooms or living rooms may go unnoticed until too late.
Improvement starts with design. Alarms should be fitted inside bedrooms and living spaces, with all units interlinked so that when one activates, every alarm sounds. Multi-sensor alarms, combining optical and heat detection, offer faster, more reliable responses while reducing false alarms.
Wider coverage and interlinking are proven to save lives and must become the rule, not the exception.
