Home Security on a Budget UK¶

Effective security measures that cost under £50 and take less than an hour to install.

Security Upgrades Under £25¶

You do not need £500 for decent home security. A door wedge alarm (Master Lock, £9.99) triggers a 120 dB siren if the door is pushed open. Window security film (3M, £15 - £20 per roll) makes glass five times harder to break. A dummy TV simulator (from £14.99) mimics flickering LED light patterns. PIR sensor lights from B&Q start at £12.98. These basic items address the ONS statistic that 68 % of burglars enter through a door - any additional resistance often makes them move on.

Mid-Range Bargains Under £100¶

A Yale Sync Smart Alarm panel costs £79.99 and pairs with up to 20 sensors. A Ring Stick Up Cam Battery (£89.99) streams 1080p video and includes free motion alerts. Window restrictors (from £8 each at Screwfix) limit opening to 100 mm - compliant with British Standard 8213-1. A Brisant Ultion cylinder (£85) offers drill and snap resistance. Combined, these upgrades cost under £250 for a typical three-bed home and qualify for 10 - 15 % insurer reductions with companies like Direct Line.
