Burglar Alarm Types UK: Wired vs Wireless Comparison Guide 2026
Published: 2026-05-29 | UK Home Guide | By Gary Pearce
Choosing between a wired and wireless burglar alarm is one of the most important security decisions you will make for your home. Both types have strengths, and the right choice depends on your property, budget, and technical confidence. This guide compares wired and wireless alarm systems across every important factor so you can decide with confidence.
Wired Burglar Alarm Systems
Wired alarm systems have been the standard in UK homes for decades. Texecom, Pyronix, and Scantronic are the leading brands, and their systems are installed by professional security companies across the country. A wired system uses physical cables to connect each sensor, the control panel, and the external siren. The reliability of a physical connection means no signal interference and no batteries to replace on sensors.
The installation cost for a wired system is higher because running cables through walls and ceilings is labour-intensive. Expect to pay 400 to 800 for a professionally installed wired system in a typical three-bedroom house. The equipment itself is relatively cheap. The benefit is longevity, a well-installed wired system can last 15 to 20 years with basic maintenance.
The main disadvantage of burglar alarm types using wired technology is flexibility. Adding sensors after installation requires running new cables, which means more drilling and disruption. Moving the control panel or extending the system to an outbuilding is difficult. If you are likely to extend your home or change the layout, a wired system may not be the best choice.
Wireless Burglar Alarm Systems
Wireless alarm systems have improved enormously and now account for the majority of new residential installations. Yale, Ajax, and Ring dominate the UK market for wireless alarms. These systems use encrypted wireless communication, typically at 868 MHz, to connect sensors to the control panel. No cables are needed between sensors, making installation much simpler.
DIY installation is a major advantage of wireless systems. You can install a full Ring Alarm kit in under an hour with just a drill and screwdriver. Yale kits start at around 80 and are genuinely beginner-friendly. Ajax is more advanced, with professional-grade sensors that detect intrusion with remarkable accuracy, at 200 to 400 for a starter kit. Ring Alarm costs around 130 for the base kit.
Battery life on wireless sensors is excellent. Door and window contacts typically last 2 to 5 years on a single set of batteries. PIR motion sensors use more power and last 1 to 2 years. All reputable systems send low battery alerts to your phone, so you never get caught out. The trade-off is that you need to keep spare batteries and be prepared to change sensor batteries periodically.
Cost Comparison: Wired vs Wireless Alarms
The upfront cost difference between wired and wireless alarms is significant. A professionally installed wired alarm from Texecom or Pyronix costs 400 to 800 fully installed, with the equipment accounting for roughly half and labour the other half. A DIY wireless alarm from Ring or Yale costs 80 to 300 for the equipment with zero installation cost. The wireless route is cheaper initially.
Ongoing costs also differ. Wired alarms typically do not require a subscription for self-monitoring, but you may have an annual maintenance contract at 50 to 100. Wireless systems often offer professional monitoring subscriptions. Ring's monitoring starts at 8 per month and includes cellular backup and a dedicated monitoring centre. Ajax monitoring costs 15 to 25 per month depending on the level of service.
Maintenance costs are lower for wired systems because there are no batteries to replace. However, if a wired sensor fails, you need an engineer visit at 50 to 100. Wireless sensor replacements are DIY and cost 15 to 40 each. Over 10 years, the total cost of ownership for a wired system is roughly 600 to 1,200, while a wireless system with monitoring is 800 to 2,000 depending on the monitoring plan chosen.
Smart Features and App Control
Smart features are where wireless alarms have a clear advantage. Ring, Yale, and Ajax all offer smartphone apps that let you arm and disarm the system remotely, receive push notifications, and check the status of every sensor. Geofencing automatically arms the alarm when you leave and disarms it when you return. These features add genuine convenience to daily use.
Integration with smart home platforms varies by brand. Ring works with Alexa and has limited IFTTT support. Yale Sync integrates with Alexa and Google Home but not Apple HomeKit. Ajax offers the most comprehensive integration, with support for Alexa, Google Home, and IFTTT, plus its own Ajax API for custom integrations. Wired systems from Texecom and Pyronix can have smart modules added, but these are expensive at 200 to 400 and less capable than native wireless offerings.
Dual-path communication is a feature worth paying for. Systems with dual-path send alarm signals over both Wi-Fi and cellular (4G) networks. If your broadband goes down, the alarm still communicates. Ring Alarm Pro includes this as standard, while Ajax offers it as an optional upgrade. This is important for burglar alarm types that rely on a stable internet connection for remote monitoring.
Decision Framework: Which Alarm Type Should You Choose?
Choose a wired alarm if you own a house you intend to stay in long term and want a set-and-forget solution. Wired systems from Texecom and Pyronix are the standard for insurance-approved installations and are recognised by all UK insurers. If you are having building work done anyway, running alarm cables during renovation is much cheaper than retrofitting.
Choose a wireless alarm if you rent, plan to move within five years, or want to install the system yourself. Ring and Yale are excellent choices for renters because you can take the system with you when you move. Ajax is the best choice if you want professional-grade detection without a professional installation.
Whichever type you choose, make sure the system is SSAIB or NSI certified if you require insurance approval. These certification bodies audit installers and systems to ensure they meet British Standards. If you are installing a DIY system, check with your insurer whether they accept it. Most insurers accept Grade 2 systems from Ring and Yale, but some require Grade 3 for premium discounts.
