Frequently asked questions
How much does a burglar alarm cost in City of London?
An intruder alarm installed in City of London is from £850 + VAT, bells-only or monitored. An intruder alarm service visit is £150 + VAT. Monitored Grade 2 systems carry a monthly monitoring fee, and every job gets a fixed written quotation after a free survey.
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.
