Home Security Guide¶
Your comprehensive UK-focused resource for protecting your home and family. This guide covers CCTV systems, burglar alarms, smart locks, and practical security measures — all grounded in British Standards, ONS crime statistics, and industry best practice.
Key Statistics
Domestic burglary in England and Wales fell 22% to approximately 327,000 incidents in the year ending December 2025 (ONS Crime Survey). Homes with comprehensive security measures — window locks, door deadlocks, timer lights, and external sensor lighting — experience up to 49 times more protection than properties with no security at all (Tseloni et al., ADR UK, 2020).
What Is a Home Security System?¶
A home security system is a combination of physical devices, electronic sensors, and monitoring services designed to detect, deter, and alert against unauthorised entry. Modern systems range from a single visible alarm box to fully integrated smart ecosystems combining CCTV, motion detectors, smart locks, and lighting controls — all manageable from a smartphone app.
Why Every UK Home Needs a Security Strategy¶
The 2025 ONS Crime Survey for England and Wales recorded 327,000 domestic burglary incidents. While this represents a 22% decrease from the previous year, the risk remains significant. Critically, homes with no security devices experience a four-fold increase in burglary incidents compared to homes fitted with a combination of security measures.
The Security Stack Approach¶
Research by Tseloni and colleagues demonstrates that layered security — combining multiple device types — dramatically outperforms single measures. A home with window locks, indoor timer lights, door deadlocks, and external sensor lights achieves 49 times greater protection than an unprotected property. An alarm alone, without complementary measures, provides minimal protection.
British Standards That Matter¶

Frequently Asked Questions¶
- Do burglar alarms actually reduce burglary risk?
- Yes, but only as part of a layered security approach. Research from the Crime Survey for England and Wales shows that a burglar alarm combined with window locks, door deadlocks, and lighting provides significantly more protection than any single measure alone. An alarm fitted in isolation without other security devices is less effective.
- Is CCTV legal in the UK?
- Yes, but you must comply with UK GDPR and the Data Protection Act 2018. If your cameras record beyond your property boundary — including public footpaths or neighbours' gardens — you likely need to register with the ICO and display visible signage. Domestic-use-only cameras that stay within your property have fewer obligations.
- What is the best smart lock for a UK home?
- The best smart lock depends on your door type and security requirements. Look for TS 007 3-star cylinder rating and Sold Secure accreditation. Keypad locks offer the best balance of convenience and security for most UK uPVC doors. For wooden doors, a British Standard 5-lever mortise deadlock remains the gold standard, with smart retrofits available.
- How much does a home security system cost in the UK?
- Basic DIY systems start at around £100-£300. Mid-range smart systems with cameras and app control cost £300-£800. Professional monitored systems with installation range from £500-£2,000+. CCTV installation typically adds £200-£1,000 depending on camera count and complexity.
- What security measure gives the best return on investment?
- Visible deterrents — alarm box, sensor-activated lighting, and clear signage — offer the highest ROI. These measures cost under £200 combined and research indicates they are the first cues burglars use when selecting targets. Insurance discounts of 5-20% for fitted and monitored alarms further improve the financial case.
