What Our Customers Say

Verified

James R. – Electrician, Birmingham

“I came out one morning to find fresh pry marks on my van door – but the ThiefStop had already scared them off. The siren went off instantly and my neighbour even said it nearly made him jump out of bed. Genuinely saved me a van full of tools. Worth every penny.”

Verified

Tom B. – Plumber, Leeds

“Fitted this to the back of my van in minutes. It’s absolutely deafening when triggered — no cheap beeping here. You can tell it’s been designed by someone who actually understands what we need on site: rugged, reliable, and no nonsense. Six months in and still on the same batteries.”

Verified

Chris D. – Builder, Bristol

“I’ve had a few tool thefts over the years, but since fitting the ThiefStop I sleep easier. I tested it a few times and it’s ridiculously loud — no thief would hang around. I’ve already recommended it to the lads on site. Simple idea, executed perfectly.”

FAQs

How long do the batteries last? 

Up to 6 months on a single set of 4 × AAA batteries (included). We are hoping the longest lasting on the market! Designed as a fit-and-forget system, ThiefStop runs reliably through all seasons with no wiring or maintenance needed.

Why ThiefStop? 

Although it was built by tradesmen, Thiefstop is for everyone with something to protect. ThiefStop is a UK-patented design that’s. tougher, and longer-lasting than cheap imports. It’s the only alarm with a rigid anti-tamper bracket and 120 dB siren powerful enough to stop thieves in their tracks.

Will it work in my van? 

Yes. ThiefStop protects vans, sheds, garages, bikes, and tools — anywhere you need fast motion-triggered security. It can be mounted on metal, wood, or plastic surfaces using the included patented bracket and Allen key.

How hard is it to install it?

It’s simple: mount, arm, and you’re done. No wiring, Wi-Fi, or app setup. Installation takes under 5 minutes, and you can arm/disarm it instantly with the included remote fob.

Is it suitable for caravans or motorhomes?

 

Absolutely. Many customers use ThiefStop in caravans, boats, and workshops. The motion-triggered design and battery power make it ideal for mobile setups.
