Frequently asked questions
How much does a burglar alarm cost in Kensington and Chelsea?
A wired bells-only system for a typical home costs around £400–£700 installed, wireless systems £500–£900, and professionally monitored Grade 2 systems £700–£1,400 plus a monthly monitoring fee.
Should I choose a bells-only or monitored alarm?
A bells-only alarm sounds at the property. A monitored alarm also alerts a 24/7 receiving centre, which can contact keyholders or — with URN registration — request a police response. Monitored systems suit higher-risk homes and businesses.
Will my insurer recognise your alarm systems?
We install to BS EN 50131 grades and are SSAIB approved for intruder alarms, which most insurers require for alarm-related discounts. Tell us what your policy specifies and we will match the grade.
Can you take over my existing alarm system?
Usually, yes. We can inspect, repair and take over servicing of most existing systems rather than replacing them outright.
