Top tips
Hiring a alarms & security, without the regret.
Four moves that separate a smooth job from a nightmare.
Grade 2 minimum for insurance.
Most insurers require NACOSS / SSAIB Grade 2 alarm certification. Lesser systems often invalidate your insurance — and £200 is the worst place to save money.
Wired beats wireless for reliability.
Hardwired alarm zones don't run out of battery, don't drift signal, don't get jammed. New builds are easy to wire; retrofits go wireless for practicality.
Get the monitoring contract terms.
Police-response, keyholder-response, monitored, unmonitored — different prices, different speeds. Read what triggers what before signing.
Test once a month yourself.
Alarms develop faults. Set up a monthly test routine — most reputable installers tell you how during commissioning.
