Home Security Basics: Protecting Your Property and Family

The Opportunistic Nature of Most Burglary

Contrary to the popular image of the calculated professional burglar, the majority of residential burglaries in the UK are committed by opportunistic offenders who are looking for easy entry and quick gain. They typically spend less than a minute assessing a property before moving on or attempting entry, which means that visible deterrents are genuinely effective: a property that looks secure, occupied, and likely to attract attention is a property that most burglars will pass by in favour of an easier target.

Understanding this changes how you think about home security. The goal is not impenetrability but sufficient deterrence to make your home a less attractive target than adjacent properties. Most of the measures that achieve this are straightforward and inexpensive.

Doors and Locks

Around a third of burglaries in the UK involve entry through an unlocked door or window. The simplest security measure is consistently locking all entry points when you leave the house and when you go to bed. This sounds obvious but is a step that many people skip in their own neighbourhood or when only stepping out briefly.

The quality of your locks matters. Front doors should have a British Standard mortice deadlock (BS3621) or a multipoint locking system. If you are not sure whether your existing locks meet this standard, a locksmith can assess them. Many home insurers require BS3621 as a policy condition.

Door frames are often the weak point rather than the lock itself. A locked door with a weak frame can be kicked in very quickly. Door reinforcement kits that strengthen the frame and hinge areas around the lock are inexpensive and significantly improve resistance to forced entry. Composite doors are generally more resistant than wooden ones.

Key security matters too. Do not leave spare keys outside the property in obvious locations (under mats, in flowerpots). Do not leave keys visible from the door, particularly where they could be hooked through a letterbox. If you lose keys or move into a new property, change the locks as a priority.

Windows

Accessible windows should have locks fitted to the frame as well as the standard catch. Key-operated window locks prevent windows from being opened far enough to allow entry even when the catch is released. Sash windows are particularly vulnerable to being forced open and benefit from sash stops or locks fitted to the frame.

Ground-floor and accessible first-floor windows should be checked every time you leave and every night. A burglar alarm sensor on frequently used accessible windows adds an additional layer of detection. Do not leave ladders accessible in the garden, as these provide easy access to higher windows and roof areas.

Lighting and Deterrence

Good external lighting is one of the most effective deterrents. Motion-activated lights around the front door, back door, and driveway illuminate anyone approaching the property and make it much more likely that activity will be noticed by neighbours. Solar-powered options make installation straightforward and cost-effective even without external electrical sockets.

When you are away from home, timer switches on indoor lights create the impression of occupancy. Smart plugs allow you to control indoor lighting remotely and randomise patterns in a way that looks more natural than a fixed timer. A property that appears occupied is significantly less attractive to a burglar than one that is clearly empty.

Burglar Alarms and Security Cameras

A visible alarm box is a deterrent in itself, whether or not it is connected to a monitoring service. Professionally installed and monitored alarms are more effective but significantly more expensive. For most homes, a well-maintained visible alarm combined with other security measures provides adequate deterrence.

Video doorbells and external security cameras have become increasingly affordable and are a genuine deterrent. Their most significant value is evidential, providing footage that can assist with identification and prosecution if a burglary does occur. Check that any cameras are positioned in accordance with ICO guidance (do not capture significant areas of public space or neighbours' property) and that footage is stored securely.

Neighbourhood and Community

Knowing your neighbours and looking out for each other is one of the most effective long-term security measures available. A neighbourhood where residents notice unusual activity and are willing to call the police is inherently more secure than one of strangers. Many local areas have Neighbourhood Watch schemes which provide resources and a community network for exactly this purpose.

Register valuable items with the Immobilise national property database and mark them with your postcode using a UV pen or security marking kit. Marked property is significantly less attractive to thieves and more likely to be returned if recovered by police.

If You Are Burgled

Do not enter a property you believe may still be occupied by a burglar. Call 999 from a safe location. If you discover a burglary after the fact, call 101. Do not touch anything that might be evidence before police have attended. Report the burglary to your home insurer. If you feel unsafe after a burglary, your local authority may be able to provide additional security measures, and Victim Support provides free emotional and practical support to crime victims.
