What Burglars Look For | Read Your Front Door

Most burglars aren't specialists. They're opportunists doing a slow walk past, running a quick mental checklist. The check takes maybe four seconds. If your door fails two or three items on that list, you've moved from background to target.

This guide runs through what that checklist actually looks like, from the pavement inward. Work through it standing outside your own front door. Take notes. Then fix what you find.

The Cylinder

This is the first thing a competent burglar looks at. Not the brand on the letterbox escutcheon, not the door handle. The cylinder.

A cylinder that protrudes more than 3 mm beyond the face of the door furniture is snappable in under thirty seconds with tools you can buy at a car boot sale. No noise. No drama. The broken half drops out, the remaining stub turns with a flathead screwdriver, and the door opens. That's snap attack, and it's been the dominant entry method on uPVC doors in Greater Manchester for well over a decade.

What to check:

• Stand at your door and look at where the cylinder sits relative to the handle plate or escutcheon. Is it proud? By how much?
• A sacrificial cut on the outer portion of a non-protected cylinder removes the security pins entirely. If your cylinder has no anti-snap feature, that's all it takes.
• Look for a TS007 3-star rating or an SS312 Diamond rating. These are tested standards, not marketing. TS007 3-star means the cylinder passed independent tests for snap, pick, drill, and bump. SS312 Diamond is arguably more rigorous: it includes an attack test where the assessor uses actual burglary tools.
• Brands worth trusting: Ultion (Brisant), Avocet ABS, Mul-T-Lock MT5+. Yale Platinum and ERA Fortis sit in a lower tier but are still meaningfully better than the white-label cylinders that ship inside new uPVC doors from developers.
• A good TS007 3-star cylinder costs £40 to £80 supply-only. Fitting takes fifteen minutes. It's the single highest-return security spend on a uPVC door, and most Horwich homes on Wallsuches Road, on the Lostock estate, and on the newer Redrow plots around Middlebrook are still running the builder-fit junk.

The Door Itself

The cylinder can be immaculate and the door can still be the weak point.

uPVC multipoint locks rely on hooks and bolts shooting into a steel keep strip in the frame. If that keep strip is shallow, corroded, or hasn't engaged because the door's dropped on its hinges, a good shoulder barge can split the frame before anything locks up. The door doesn't look broken from a distance, which matters to a burglar doing a walk-past.

What to check:

• Lift the handle firmly before you turn the key. All multipoint bolts should engage. If the door feels loose or you can see daylight around the frame edge, the keep strip isn't seated properly.
• Look at the hinges from outside. Three hinges on a composite or solid timber door is standard. Two hinges on a heavy composite door is a problem: the door can be lifted off the hinge side under sufficient force.
• Run your finger along the frame at the lock side. Soft, crumbling, or painted-over rot means the keep bolts are shooting into wood with the structural integrity of damp cardboard.
• Composite doors with PAS24 certification have been tested to withstand a sustained physical attack including crowbar assault and body impact. If you don't know whether yours has it, check the door manufacturer's paperwork or the CE/UKCA marking. PAS24 is an entry-level requirement for Secured by Design, which Greater Manchester Police advocate.

The Letterbox

Some things a burglar can do through a standard letterbox: fish for keys on a hook inside, feel for a door chain or night latch to manipulate, and, less commonly, access release mechanisms on internal handles.

Key hooks near the front door are extraordinarily common. I've attended enough jobs on Brownlow Fold and in Blackrod to say: if you've got a Lakeland key hook on a dado rail two feet from the door, a fishing line and a wire hook can have your car keys in sixty seconds.

What to check:

• Open your own letterbox from outside and look at the angle of view. Can you see a key hook? A Yale-style nightlatch? Anything a wire can catch?
• A letterbox guard on the inside deflects both the view and the reach. They're £10 to £20 and fit with four screws.
• A double-flap letterbox adds minimal resistance on its own, but it does limit sightline.
• Positioning: move keys to a drawer or cabinet that's not visible from the door at all.

Lighting and the Porch

A dark porch is not neutral. It's a positive advantage for someone trying your door.

A porch with a deep reveal, low soffit, and no sensor light gives three or four seconds of invisible working time, which is enough to attempt a snap. The street might be busy. Nobody sees what's happening inside a shadow.

Horwich has a range of porch geometries. The semi-detached interwar properties around Ramsbottom Road and Victoria Road tend to have shallow open porches, decent natural lighting from the street. The bungalows toward Adlington and the newer builds near the Middlebrook retail park have everything from full enclosed porches with half-glazed inner doors to deep brick recesses with almost no ambient light.

What to check:

• Stand at your door at 10 pm. Is the area around the cylinder and handle well lit, or are you working in shadow?
• A PIR-triggered light with a 2,000 lumen output and a wide detection angle makes casual snapping far riskier. The light doesn't have to be expensive. It does have to be correctly angled: pointed at the door face, not up at the porch ceiling.
• Timer lights on an interior hall circuit visible through glazed door panels suggest occupancy. They cost almost nothing.

The Side Gate

Rear access is responsible for a significant proportion of residential break-ins. Bolton and Wigan councils have published neighbourhood watch data showing that side and rear access routes are used more often than front doors for actual entry, even when the initial survey happens at the front.

A burglar walking past your front doesn't only look at the door. They look at what's beside it.

What to check:

• Is the side gate visible from the pavement? Solid-panel timber gates that block sightlines into the rear are preferable to open-bar metal gates. Both can be climbed; only one lets someone assess the back of your house before committing.
• Gate hardware matters: a gate bolt with a BS EN 12320 rating and a close-shackle padlock rated Sold Secure Gold or Silver is meaningfully harder to force than a standard barrel bolt with a £4 padlock. An Abus 83/55 or a Squire SS50CS in hardened steel is a reasonable minimum.
• Height: anything under 1.8 m that isn't topped with trellis, fence spikes (check permitted development rules in Aspull and the conservation areas near Horwich town centre before fitting), or prickly planting is climbable with no tools.
• Does your gate have a lock? Or just a bolt you lift from the inside? If the top of the gate is visible from outside, a wire can often lift that bolt.

Things Left Outside

Bins under a ground-floor window are a stepladder. A ladder in the side return is a ladder. A child's trampoline against a fence line is a launching platform. None of these are dramatic. All of them have been used on properties around Westhoughton and Lostock that I've attended afterward.

What to check:

• Wheelie bins: park them away from fence lines and windows when not in use for collection. One wheelie bin against a 1.8 m fence reduces the effective obstacle to roughly 1.1 m.
• Garden tools, ladders, and anything stackable should be locked in a shed or garage. This applies permanently, not just when you go on holiday.
• Look at your property from across the road. Is there an obvious climbing route to a first-floor window? Older semis in Bromley Cross and Adlington often have flat-roofed kitchen extensions that sit directly under a bedroom window.

What Your Car Says

A car on the drive tells a burglar whether you're home. Two cars, one gone: there's a good chance one person is in. No car at 3 pm on a Tuesday: nobody home. This is basic situational reading and it costs the burglar nothing.

This doesn't mean hide the car. It means don't let the car be the only occupancy signal.

What to check:

• Timer plugs on lamps visible through the front window create the impression of activity. They cost £5 each.
• A TV simulator (a device that mimics the light pattern of a television) is visible through curtains and is a stronger occupancy signal than a static lamp.
• Don't leave garage door remotes in the car visible from outside. Particularly relevant if your garage connects directly to the house, which is increasingly common on the Redrow and Countryside developments around BL6.

Visible Alarm Boxes

A bell box on the front of the house is a deterrent signal. It's also something a burglar evaluates. An obviously ancient dummy box with faded casing and no visible LED suggests the system isn't active. A modern box with a flashing LED and a fresh install suggests it probably is. That's the distinction.

What to check:

• If you have an alarm, is the external bell box in reasonable cosmetic condition? A box that looks fifteen years old and sun-bleached signals low maintenance commitment generally, which signals corner-cutting on other security decisions.
• Position: the box should be visible from the approach to the property, not tucked around the side where it can only be seen once someone is already in the side passage.
• A monitored alarm (one connected to an Alarm Receiving Centre) is meaningfully more effective than a bell-only system. Bells are ignored in residential streets. A confirmed alarm with police response is different.

The Door Furniture Itself

This sounds minor. It isn't.

A knackered letterbox, a hanging door number, paint peeling around the frame: these are all signals that the occupant isn't paying close attention to the property. Properties that look well-maintained signal the opposite of easy picking. It's not about aesthetics. It's about the inference a passer-by draws.

What to check:

• Does the door handle or the cylinder furniture show obvious wear? A severely worn handle that wobbles suggests the multipoint mechanism may not be engaging fully.
• Is the door frame painted, intact, and without visible rot or damage from a previous attempted entry? Signs of a previous forced entry that haven't been properly repaired (filled with filler, repainted hastily) tell a story.
• Stickers: 'Neighbourhood Watch', 'Ring doorbell in use', or visible camera housings all add a small but real deterrent effect. They shift the risk calculus slightly toward moving on.

The Quick Four-Second Test

Stand on the pavement outside your own front door. You have four seconds.

Three fails is enough. Fix the cylinder first. It's the highest-yield change for the least money and least disruption.
