Frequently Asked Questions

Wired or wireless — which is better?+

Both have advantages. Wired systems are highly reliable and ideal for new builds or major renovations. Wireless systems are faster to install, less disruptive, and perfect for listed buildings or rentals where drilling isn't practical.

Are your alarm systems insurance-approved?+

Yes. We install insurance-approved alarm solutions. Many insurers offer reduced premiums for professionally installed and maintained intruder alarm systems — we can provide the documentation your insurer needs.

Do you service alarms installed by other companies?+

Yes. We support all systems, including those installed by other companies. We'll carry out a full assessment and advise on any remedial work required — with no obligation to replace the system unless necessary.

How quickly can you respond to an alarm fault?+

We aim to respond to emergency call-outs as quickly as possible, with same-day attendance available across London in most cases. Call 0207 060 3875 for urgent repairs.
