Wireless Alarm Systems
Battery-powered sensors you fit yourself — no drilling or wiring
Pros
- No drilling, chasing walls or professional installer required to get a full kit running
- Easy to expand — add extra sensors or move them if you rearrange a room
Cons
- Ongoing battery replacement across multiple sensors is a genuine recurring task, not a one-off
- Entry-level wireless kits are typically BS EN 50131 Grade 2 — check the grading if you need a higher-security-rated system
About Wireless Alarm Systems
A wireless alarm kit typically pairs a control hub with door/window contact sensors and PIR motion detectors, all battery-powered and fixed with adhesive pads or a couple of screws — no cable runs through walls or ceilings needed, so most people can install a full kit in an afternoon without an electrician. The genuine trade-off is ongoing maintenance: with several sensors around a property, expect to be replacing batteries somewhere in the system roughly once a year, and a system left unmaintained (flat battery, sensor fallen off a frame) offers a false sense of security. Systems tested to the BS EN 50131 European/British intruder alarm standard (usually Grade 2 for a typical domestic wireless kit) are a useful signal of build quality if you want to compare options on more than marketing claims.

Frequently asked questions
Do wireless alarms count for a home insurance discount?
Sometimes, but not automatically — insurers that offer alarm discounts usually specify a minimum standard (often referencing BS EN 50131 grading) or require NSI/SSAIB-accredited installation for the biggest discounts. A self-installed wireless kit may still help, but check your specific policy wording rather than assuming.
Are you a security installer or manufacturer yourselves?
No — Home Security Innovations is an independent comparison and information service. We recommend checking any professional installer’s NSI or SSAIB accreditation directly before commissioning work.
Is all the pricing on this site guaranteed?
No — costs mentioned are typical ranges reported by trade and industry sources, not fixed quotes. Always get more than one itemised quote before committing, particularly for professionally installed systems.
What happens after I request a quote?
A partner installer or supplier reviews your details and gets in touch to discuss your property and requirements — there’s no obligation to proceed with any quote.
