Burglar Alarm vs Locks | What to Buy First

Alarm companies have convinced most homeowners in Horwich, Bolton and across BL6 that a bell box is the first thing to buy. It isn't. It might be the last.

This isn't a knock on alarms. A decent monitored system from a reputable installer does something useful. But useful-second is not the same as useful-first, and the order matters enormously when you're deciding where £400 goes.

What an Alarm Actually Does

An alarm detects and signals. That's the whole job. A PIR trips, a siren sounds, a notification lands on your phone or a monitoring centre's screen. At that point, someone is already inside your home. The best-case outcome is they leave quickly. The average police response to a residential alarm activation in Greater Manchester is not fast enough to catch anyone. Most activations are false. Responders know this.

So you've spent £350 to £800 on hardware, plus £15 to £30 a month on monitoring, for a system whose success condition is that the burglar runs away before stealing much. That's not nothing. But it's a long way from prevention.

What a Lock Actually Does

A properly specified cylinder and lock on a solid door stops entry. Not delays it by thirty seconds. Stops it.

The Office for National Statistics consistently shows that the majority of domestic burglaries are opportunistic. A door that resists a snap attack, a kick, or a bump simply doesn't get entered. The burglar moves to a softer target. There are plenty in any street in Lostock or Brownlow Fold.

A TS007 3-star cylinder, say an Ultion or an Avocet ABS, costs £50 to £90 fitted. It's anti-snap, anti-drill, anti-pick. A SS312 Diamond-rated deadlock, tested under the same logic, adds another layer. Combine those with a PAS24-tested door and you've built something that a casual break-in attempt won't beat. Total outlay: under £200 in most cases. No monthly fee. Ever.

Why Alarms Get Sold First

Subscriptions. A one-off lock installation earns a locksmith £80. A monitored alarm earns an alarm company £25 a month for five years. The incentive structure is obvious, and it shapes every leaflet, every Google ad, every free home survey that somehow always ends in a quote for a full alarm package.

There's also the visibility argument. A bell box on a fascia board in Wallsuches or Middlebrook is a signal to the neighbourhood. Fine. A TS007 cylinder is invisible. People can't see what they've bought, so they feel they haven't bought anything.

The Fair Caveat

For a home that already has solid, well-specified locks and doors, an alarm genuinely adds something. Rear doors, garage entry points, ground-floor windows: a detector on these catches what physical security can't always cover. If you're a landlord with a portfolio across Blackrod or Adlington, a monitored system with remote alerts has real practical value. And for high-value properties where physical hardening alone isn't enough, layering makes sense.

But that's the order: harden first, then signal.

The Sensible Sequence

1. Get your entry-point cylinders to TS007 3-star standard.
2. Check your door frame and multipoint lock engage properly. A Fuhr, GU or Maco multipoint that doesn't fully latch is worse than useless.
3. Add BS3621 deadlocking where you don't already have it.
4. Then, if budget allows, consider an alarm as a secondary layer.
