What is the most common way burglars break into UK homes?

The most common method is through a door, with 76% of burglars entering this way. The front door accounts for 62% of all entries, with lock snapping being the most widely used technique on homes with uPVC or composite doors fitted with standard euro cylinders.

How long does the average burglary take?

Most residential burglaries take between 2 and 10 minutes, with the average closer to 5 minutes. This is why slowing a burglar down by even 2-3 minutes is so effective — most will abandon the attempt and move on to an easier target.

Do dogs really deter burglars?

Yes, research consistently shows dogs are one of the most effective deterrents. It is the noise rather than the size that matters — barking draws attention from neighbours and passers-by, which burglars want to avoid. Even a small, noisy dog is a genuine deterrent.

Is my Coventry home at risk of lock snapping?

If you have a uPVC or composite door with a standard euro cylinder (the type of lock with a keyhole on both sides of the door), then yes. Most homes in Coventry built or refurbished in the last 20 years have this type of door. An anti-snap cylinder upgrade typically costs £90-£120 fitted and eliminates the risk.

How Burglars Actually Break Into UK Homes (and How to Stop Them)

76% of burglars enter through a door. 62% use the front door. Here is what the data says about how break-ins happen — and the practical steps that actually prevent them.

Nobody wants to think about a break-in happening to them. But understanding how burglaries actually work — not Hollywood-style heists, but the real thing — is the single best way to stop one happening to your home.

I have been fitting locks and securing homes across Coventry and Warwickshire for years. I have seen the aftermath of hundreds of burglaries. The patterns are remarkably consistent, and the good news is that most break-ins are preventable with straightforward upgrades that do not cost a fortune.

How Do Burglars Get In? The Numbers

The data from the Office for National Statistics (ONS) and police forces across the UK paints a clear picture:

**76% of burglars enter through a door** — not a window, not the roof, not some elaborate entry point

**62% use the front door** — the one you walk through every day

**Around 24% come through the back door** — usually less visible to neighbours

**Only about 22% enter through a window** — and most of those are ground-floor windows left open or unlocked

These numbers matter because they tell you exactly where to focus your security budget. If you are spending money on window alarms but your front door has a standard euro cylinder that can be snapped in 20 seconds, you are solving the wrong problem.

The Most Common Techniques

Lock Snapping

This is the number one burglary method in the UK, full stop. If your home has a uPVC or composite door with a standard euro cylinder, it is vulnerable. The technique involves gripping the cylinder with mole grips or pliers, snapping it at the weak point, and using a screwdriver to operate the lock mechanism. It takes 10-30 seconds and makes surprisingly little noise.

I have written a detailed guide on [what lock snapping is and how to prevent it](/blog/what-is-lock-snapping) — it is worth reading if you have a euro cylinder door.

Lock Bumping

A bump key is a specially cut key that exploits the pin-tumbler mechanism in most standard locks. The key is inserted, tapped with a screwdriver handle, and the pins jump to the shear line. It works on a frightening number of standard cylinders and leaves almost no trace.

Forced Entry

Some burglars skip the subtlety entirely. A firm kick to a poorly fitted door, a shoulder charge against a weak frame, or a screwdriver jammed into a gap beside the lock. Wooden doors with shallow mortice locks and weak frames are particularly vulnerable. I regularly see doors that have been kicked in where the frame has simply split because the screws holding the strike plate were only 15mm long.

Reaching Through Letterboxes

A surprising number of burglars use tools — or just their hand — to reach through a letterbox and turn a thumb-turn lock, pull a door chain, or hook keys left on a hall table. A [letterbox guard](/services/lock-upgrade) is a cheap fix that eliminates this risk entirely.

How Long Does a Burglary Take?

Most residential burglaries in the UK take **between 2 and 10 minutes** from entry to exit. The average is closer to 5 minutes. They are not spending hours searching your home. They grab what is visible and easy to carry — phones, laptops, jewellery, car keys, cash — and leave.

This means anything that slows them down by even 2-3 minutes dramatically changes the equation. Research by police forces consistently shows that if a burglar cannot get in within 2-3 minutes, most will give up and move to an easier target.

Opportunistic vs Targeted Burglaries

Understanding this distinction changes how you think about security.

Opportunistic Burglars (the majority)

Most burglaries are opportunistic. A burglar walks or drives through an area, spots a vulnerability — an open window, a flimsy door, no visible security — and takes the opportunity. These burglars are looking for the path of least resistance. They are not planning for weeks. They might not even know which street they will hit until they see an opportunity.

This is actually good news. It means that **anything you do to look harder than your neighbours' homes makes a difference**. You do not need to build a fortress. You need to not be the easiest option on the street.

Targeted Burglaries

A smaller percentage of burglaries are targeted — someone has identified your home specifically, perhaps because they know you have valuable items, or they have observed your routine. These are harder to prevent with locks alone, but layered security (locks, alarms, CCTV, lighting, and good habits) makes even targeted attempts significantly harder.

What Actually Deters Burglars?

Forget the myths. Here is what the evidence and experience actually shows:

Dogs

Research consistently ranks dogs as one of the top deterrents. It is not about the size of the dog — it is about the noise. A barking dog alerts neighbours and draws attention, which is the last thing a burglar wants. Even a "Beware of the Dog" sign has some deterrent value, though a real dog is obviously better.

Visibility and Sightlines

Burglars hate being seen. If your front door is clearly visible from the street, from neighbours' windows, or from a busy path, it is a much less attractive target. High hedges, solid walls, and recessed doorways all provide cover for someone trying to force a lock. If you have a recessed porch, consider whether it provides too much concealment.

Quality Locks

This is my area, obviously, but the data backs it up. Homes with [anti-snap cylinders](/blog/anti-snap-locks-compared), BS3621 mortice deadlocks, and properly fitted multipoint locking systems are significantly harder to break into. A quality anti-snap lock like an Ultion or ABS cylinder costs from around £90-£120 fitted — that is the price of a meal out for two to protect everything you own.

Check our [lock upgrade service](/services/lock-upgrade) or see the full [price list](/prices) for what different upgrades cost.

Signs of Occupancy

Burglars prefer empty homes. Anything that makes your home look occupied reduces the risk: lights on timers, a radio playing, a car on the drive, post collected, bins brought in. When you go on holiday, these small things matter enormously.

Alarm Systems and CCTV

Visible alarm boxes and CCTV cameras do deter opportunistic burglars. The key word is "visible" — a hidden camera might help police afterwards, but it does nothing to stop someone trying. I have covered this in detail in my post on [whether alarms and CCTV actually deter burglars](/blog/do-burglar-alarms-cctv-deter-burglars).

Good Lighting

Motion-sensor lights on approach paths, driveways, and around doors are effective and cheap. A well-lit house is an unattractive target. You can get decent solar-powered motion sensor lights for under £20.

What Does NOT Work as Well as People Think

**Dummy alarm boxes** — experienced burglars can spot them, and they give you a false sense of security

**Leaving a light on in the same room 24/7** — this actually signals you are away. Use timers that vary

**Hiding a spare key under a mat or plant pot** — burglars know every hiding spot. Use a [key safe](/services/lock-change) instead

**Relying solely on insurance** — insurance pays out after the fact, but it does not replace the feeling of violation that comes with a break-in, and it will not cover sentimental items

What to Do Right Now

If you are reading this and wondering where to start, here is my honest recommendation as a Coventry locksmith who sees this every day:

**Check your front door lock first** — if it is a standard euro cylinder on a uPVC or composite door, [replace it with an anti-snap cylinder](/services/lock-change). This is the single most impactful upgrade you can make

**Check your back door** — make sure it has key-operated bolts, not just a handle you can open from inside

**Walk around the outside of your home** — look at it like a burglar would. Where are the hidden spots? Where could someone work on a lock without being seen?

**Read the full [home security checklist](/blog/home-security-checklist-2026)** — it covers every room and every potential weak point

If you want a professional assessment, I offer security checks across Coventry and the surrounding areas. Call me on 07735 336175 and I will walk round your property, identify the weak points, and give you an honest quote for the upgrades that will make the biggest difference. No pressure, no scare tactics — just practical advice from someone who sees this every week.
