SiteKiln gives you plain-English information, not legal, insurance or financial advice. Always check your own policies, contracts and local police guidance.
You can't make yourself theft-proof. But you can make your van and your site look like "too much hassle" compared with the next one along. This is about slowing thieves down, making noise, and making your kit traceable.
1. Your van: what to fix first
Think of your van as a mobile tool safe, not just a vehicle.
Quick wins you can do this week
- Park smart: nose-to-wall, side door tight against a wall or another vehicle, under lights or CCTV wherever you can.
- Empty the big-ticket stuff overnight where possible -- lasers, cordless kits, nail guns, specialist tools.
- Always lock up, shut windows and don't leave tools on seats or in view, even "just nipping in for two minutes".
Hardware that actually makes a difference
- Fit proper aftermarket deadlocks or slamlocks on side and rear doors -- designed to resist drilling and basic tools much better than factory locks.
- Add an internal security cage or tool vault bolted through the floor, so even if they get a door open they can't strip the van in 30 seconds.
- Use a visible steering-wheel lock and decent alarm -- you're trying to make them think "too noisy, too long, move on".
Example: Stephen's new van setup isn't fancy -- upgraded locks, bolted vault, parking smart -- but it means nobody can repeat the "22 seconds and everything's gone" trick on him again.
2. Your site: stop being the easy hit
On site, thieves are looking for lazy habits and weak storage.
Basics every site should have
- Solid perimeter: proper fencing or hoarding, locked gates, as few access points as possible.
- Lighting and CCTV on entrances, cabins and storage, with signs up so everyone knows it's there.
- One way in, one way out for vehicles, with someone responsible for challenging unknown faces.
Tool control, not tool chaos
- Lock tools away whenever they're not in use -- steel containers, site safes and tool vaults, not "just in that room".
- Run a simple sign-in / sign-out for expensive kit so you know who had what, and when.
- Clear the decks at the end of the day -- no piles of kit left in corridors "just for tonight".
Example: most big hits happen when sites shut down and "we'll do a proper tidy tomorrow" turns into "everything's laid out ready for them". A ten-minute sweep at the end of the day is cheaper than replacing £5k of tools.
3. Marking, logging and tracking your tools
This is the boring bit that pays off when things go wrong.
Make tools harder to sell
- Mark tools in at least one visible and one place -- engraver, UV pen, paint, or forensic marking.
- Use a consistent ID (company name and postcode, or a unique code) so anyone can see they're yours.
- Consider forensic marking kits -- police and second-hand dealers are used to checking for them.
Prove what's yours
- Keep a live inventory: make, model, serial number, photos and rough value for each key tool.
- Register tools on a property register like Immobilise and with Stolen Tools UK so there's a digital record police and the trade can check.
- For your most expensive kit, look at tool tracking tags or systems that ping location if something moves when it shouldn't.
When the Met pulled £2m of suspected stolen tools out of a warehouse, they could only reunite a fraction with owners because hardly anything was marked or logged properly. That's the gap you're closing here.
4. Common mistakes
- "I'll upgrade the locks next month" -- thieves don't wait for your schedule. Factory locks on most vans are barely a speed bump.
- Leaving tools in the van because "I'm up early anyway" -- that's exactly when they hit: 2am-5am when you're asleep.
- CCTV with no lighting -- a camera in the dark records a blurry shadow, not a face. Lights and cameras together.
- Marking tools but not logging serials -- marking slows resale, but without serials and photos you still can't prove ownership if police recover them.
- Sign-writing your van with a full tool list -- "SB Multitrade -- Hilti, Makita, DeWalt" is basically a shopping list for thieves.
5. Van and site security checklist
Use this as your "walk-round" list. Tick off what you've done, circle what needs doing next.
Vans
- Van has aftermarket deadlocks or slamlocks on all load doors.
- Internal cage or bolted tool vault fitted for key kit.
- Steering lock and alarm in place and used every time.
- Regular parking spot is lit / overlooked / on CCTV where possible.
- Parking nose-in or nose-to-wall so side/rear doors are hard to access.
- Policy for what never stays in the van overnight (and everyone knows it).
Sites
- Fencing or hoarding all the way round, with locked gates.
- CCTV and lighting on main entrances, cabins and storage.
- Secure lockers / vaults for tools, not just open rooms.
- End-of-day "tool sweep" routine in place and owned by someone.
- Simple sign-in / sign-out or allocation list for expensive kit.
Tools
- All key tools marked visibly and in at least one spot.
- Inventory kept up to date with serials and photos (see Doc Hub template).
- Tools registered on Immobilise / similar and with Stolen Tools UK.
- Trackers or tags fitted to the most valuable items and boxes.
None of this is magic. But if your van is locked, caged, marked and parked smart, and your sites run a "lock it up, log it, clear it" routine, you've moved yourself out of the "easy money" category and into "too much work, try somewhere else".
6. Who to contact
- Your van dealer / locksmith -- for aftermarket deadlocks, slamlocks and security cages. Ask for construction-spec, not just "extra lock".
- Stolen Tools UK -- register your tools and get alerts: stolentoolsuk (Instagram/social)
- Immobilise -- free national property register used by police: immobilise.com (free)
- Your insurer -- check what security upgrades they require or reward with lower premiums. Some policies mandate deadlocks for overnight cover.
- Local crime prevention officer -- most police forces offer free security surveys for businesses. Ask via 101.

Common questions
Will insurance cover stolen tools from van?
Only if you have a specific Tools-in-Transit policy. Standard van insurance does not cover the contents. Most tool policies also exclude theft from an unattended vehicle overnight. Read the small print: most insurers require the van locked, alarmed, and parked off-street between 9pm and 6am.
What is Immobilise for tool registration?
Immobilise is the UK's national property register, used by every police force. Registering tools with serial numbers means stolen items can be traced, returned, and used as evidence in prosecution. Registration is free at immobilise.com and police regularly check seized goods against it.
