Most insurers require NACOSS / SSAIB Grade 2 alarm certification. Lesser systems often invalidate your insurance — and £200 is the worst place to save money.
Hardwired alarm zones don't run out of battery, don't drift signal, don't get jammed. New builds are easy to wire; retrofits go wireless for practicality.

Alarms & Security explained
Everything you need to know before hiring a alarms & security.
Protecting your home is about more than just installing a bell box on the wall. Professional alarm and security specialists design, install, and maintain systems that safeguard your family, your property, and your peace of mind. From traditional wired burglar alarms to sophisticated 4K CCTV networks and smart home integrations, these experts ensure your first line of defence is robust and reliable.
In the UK, security installers work across a range of technologies, including intruder alarms, motion sensors, video doorbells, and electronic gates. Whether you are looking to secure a new build or upgrade an aging system, a qualified security professional provides the technical expertise to eliminate "blind spots" and ensure your system meets insurance requirements.
Hiring a security professional involves a structured process to ensure your property is adequately protected without unnecessary expense. Here is the typical workflow:
While DIY "plug-and-play" security kits are popular, they often lack the reliability of a professionally installed system. A specialist understands the nuances of sensor placement—ensuring, for example, that a PIR sensor isn't triggered by a radiator or a pet, which leads to frustrating false alarms.
Crucially, many UK home insurance providers offer discounted premiums only if your security system is installed and maintained by an accredited professional. Systems installed by companies registered with the NSI (National Security Inspectorate) or SSAIB (Security Systems and Alarms Inspection Board) meet the rigorous British Standards (BS EN 50131) required for police response in the event of an activation.
Furthermore, professional installers handle the complex networking required for modern CCTV and smart locks. They ensure your data is secure, your cameras comply with UK privacy laws regarding neighbouring properties, and your smart devices are protected against hacking through secure configurations.
The cost of security depends on the size of your property, the complexity of the hardware, and whether the system is "monitored" (connected to a call centre) or "unmonitored."
| Service | Low £ | High £ | Notes |
|---|---|---|---|
| Wireless Burglar Alarm (3-bed house) | £450 | £750 | Includes hub, 3-4 sensors, and siren. |
| Wired Burglar Alarm (3-bed house) | £650 | £1,100 | Higher labour cost due to cabling. |
| CCTV System (4 Cameras + NVR) | £700 | £1,500 | Price varies by resolution (4K) and storage. |
| Smart Door Lock Installation | £250 | £500 | Includes hardware and setup. |
| Annual Alarm Maintenance | £90 | £180 | Includes battery checks and testing. |
| Monthly Monitoring Contract | £15 | £45 | Ongoing monthly fee for 24/7 response. |
Note: Labour rates for security specialists typically range from £50 to £80 per hour. Costs may increase if your property requires extensive cabling through solid walls or if you opt for high-end features like facial recognition or thermal imaging.
Security is a matter of trust. You are giving a stranger access to the layout and vulnerabilities of your home, so due diligence is essential.
Wireless systems are faster and cleaner to install, making them ideal for finished homes. Wired systems are generally considered more reliable over long distances and are preferred for new builds or major renovations where cables can be hidden behind walls easily. Modern high-end wireless systems are now almost as stable as wired versions.
Not necessarily. Many systems allow "self-monitoring" via a smartphone app for free. However, if you want a professional monitoring station to call the police or a keyholder when the alarm triggers, you will need to pay a monthly subscription fee. Some smart cameras also charge a monthly fee for cloud video storage.
In many cases, yes. Most UK insurers recognise that an NSI or SSAIB-approved alarm reduces the risk of theft. Be sure to inform your insurer about the specific make and model of your system, and whether it is professionally maintained, to see if you qualify for a discount.
Both are UK-recognised certification bodies for the security industry. NSI (National Security Inspectorate) is often seen as the "gold standard" and is preferred by some commercial insurers, while SSAIB (Security Systems and Alarms Inspection Board) is widely respected and common among residential installers. Both ensure the installer is competent and insured.
