Garage Security Guide UK¶

Essential garage security guide for UK homeowners covering locks, alarms, CCTV, and structural upgrades to prevent break-ins and theft.

Garage Break-In Risks in the UK¶

Garages are targeted in 28% of UK burglaries according to ONS data, with average contents valued at £2,500 - £5,000. Up-and-over doors are the weakest point - 80% can be forced open with a screwdriver in under 30 seconds. Garage security upgrades range from £20 (replacement lock) to £400 (smart alarm system with cameras). Brands like Hormann, Garador, and Cardale offer reinforced doors from £400 - £1,200. British Standard PAS 24:2016 certification indicates a door has passed forced-entry testing.

Garage Alarm and CCTV Recommendations¶

Wireless garage alarms from Yale and Ring (£30 - £130) include door sensors, motion detectors, and smartphone alerts. The Ring Garage Contact Sensor (£39) integrates with Ring Alarm systems. For CCTV, the Reolink Argus 3 Pro (£110) offers 2K resolution and a built-in spotlight. Place a PIR motion detector inside the garage covering the main entry point. Install a wall-mounted safe bolted to concrete for tools and valuables.

FAQ¶

What is the weakest part of a garage?: The up-and-over door locking mechanism - many can be forced with a screwdriver. Replace with a side-mounted locking bar or shoot-bolt system.
Do I need planning permission for a new garage door?: Usually no, unless you live in a listed building or conservation area. Check with your local planning authority before making changes.
Will a garage alarm affect my home insurance?: Yes - installing a Thatcham-approved alarm can reduce premiums by 5 - 15%. Notify your insurer to ensure the discount is applied. For more information see our Shed Security Devices and Alarms UK.
