Every trade faces unique risks. Here's what could go wrong and why the right cover matters.
The single most important thing an alarm installer needs to understand about their insurance is that ordinary public and product liability policies almost always exclude the one claim you're most likely to face: the system not working.
Efficacy (also called inefficacy or "failure to perform" cover) protects you against legal liability for injury or property damage arising from an alarm, sensor or system failing to perform its intended function — for example, an alarm that doesn't go off, or one that activates but isn't monitored correctly.
Most general liability and product liability policies specifically exclude "failure of any fire or intruder alarm to warn of fire, smoke or intrusion." This means a standard policy can cover you for damage you cause while installing, but not for the alarm simply not working — exactly the scenario clients are most likely to claim over.
Evidence of efficacy insurance is required by NSI and SSAIB, the leading inspectorate bodies in the UK fire and security industry, as a condition of membership. If you hold or want this accreditation, check your policy names efficacy cover explicitly rather than assuming it's included.
Efficacy cover is usually arranged at £1 million, £2 million, £5 million or £10 million, depending on the type of installation and client. A 2018 Local Government Association report found that mains-powered smoke alarms failed to perform in around 20% of residential fires — a reminder of how real this risk is, regardless of how carefully a system was installed.
A strong policy covers the specific risks of your trade — from site accidents to equipment theft and client disputes.
Covers legal costs and compensation if a client or third party is injured or has property damaged as a result of your business activities.
Covers claims of negligence, errors or bad advice. Essential if you provide professional services, advice or designs to clients.
Legally required if you employ anyone. Covers employee injury or illness claims. Minimum £5 million cover by law.
Covers business equipment, tools, cameras and specialist kit against theft and accidental damage — at your base and on the move.
Replaces lost income if your business is unable to operate due to an insured event. Covers ongoing fixed costs during recovery.
Covers legal costs for contract disputes, debt recovery, HMRC investigations and employment tribunal defence.
A few things worth checking before you buy, whichever UK insurer or broker you compare.
Check the limit matches what your contracts, landlord or clients require — common tiers are £1m, £2m, £5m and £10m depending on trade and risk.
Professional and liability covers are often "claims-made" — cover depends on holding a live policy when a claim is made, not just when the work happened.
Read what's excluded, not just what's covered. Sub-contractor work, specific activities, or work carried out overseas are common gaps.
Before buying, confirm any insurer or broker is authorised and regulated by the Financial Conduct Authority — check the register at register.fca.org.uk.
