The Most Common Types Of Theft From Construction Sites

Theft from construction sites is one of the most pressing concerns for those in the industry. It’s an epidemic that affects multiple aspects of your business, from health and safety breaches caused by lost materials and stolen fencing to costly project delays. That doesn’t address the emotional impacts, either – stress, anxiety, depression and a loss of motivation all contribute towards a sector that constantly battles theft.

But what’s being stolen, and why? 

What Are The Most Stolen Items From Construction Sites?

Handheld power tools (such as drills, sanders, or multitools) are statistically the most targeted items on construction sites, with more than 80% of tradespeople falling victim to the crime over the course of their careers.

However, while they’ve proven the most popular among thieves, they’re not their only item in a criminal’s sights. That same report points towards 31% of all trade thefts coming at building sites – an alarming state of affairs for projects on timelines and even tighter budgets.

What does that mean in practice? Here are the most common types of theft from construction sites, and what impact they can have.

1. Power Tools & Equipment

The most stolen item from construction sites is handheld power tools. That includes more conventional, jack-of-all-trades items like multitools and power drills, to specialist options for specific tradespeople (like handheld sanders for carpenters and joiners, or paint sprayers for painters and decorators).

These are, by design, easy to carry and built for the fast-paced nature of the modern construction industry. However, while that portability makes them ideal for a flexible tradesperson, it also contributes towards their ease of access for criminals and, ultimately, the opportunity for thieves to sell them on quickly and with minimal options for tracking. 

A report from construction branding firm Monster-Mesh showcases the extent of that, with an estimated 30,848 tool thefts reported over 2025 – a concerning 16% year-on-year rise. It equates to roughly one theft every 17 minutes, and an estimated overall cost to the UK’s tradespeople of in excess of £19 million.

It’s further perpetuated by a growing and often-undetected black market. Car boot sales and unregulated markets frequently see tools on their tables, often with barcodes or serial numbers scratched out in an attempt to mask the trail back to their rightful owners. 

The Guardian’s April exposé sheds light on both this and more organised bulk thefts like the recent Metropolitan Police bust of more than £2 million worth of stolen tools in Ilford earlier this year. Tool theft represents the biggest concern for theft from a construction site.

It’s yet to be recognised more widely as such, though. Although a broader discussion around van and tool theft was part of the Early Day Motions in late November of last year, it’s still yet to become part of the Equipment Theft (Prevention) Act 2023. 

There are green shoots, however. Community initiatives like Stolen Tools UK are springing up in an attempt to unite the industry in campaigning for stricter punishments for tool thieves,  alongside a “people-powered” network of both local police forces and active tradespeople. That’s alongside localised work like that of the Met Police, which seeks to curb those more protracted concerns.

2. Cabling, Wiring & Electricals

One of the more less obvious concerns for theft from construction sites, cables and wiring are a major target for thieves who know their market. Research from LetsRecycle puts the estimated cost of cabling and metal theft to the UK economy at £500 million – an eye-watering figure that’s particularly concerning for projects like HS2, where cabling means incredibly costly delays to a much-anticipated, cross-country project.

It’s not reserved for large-scale construction, though. Retail refits that look to install EV chargers as part of their renovations are at risk, as per a report from the EV chargepoint company Allego UK. Through FOI requests issued to over 30 local police forces, they uncovered over 200 instances of theft from EV chargers.

The thieves look to target expensive copper wiring and cables, as well as the electrical components themselves. There’s a substantial market for those, too – specialist metal recycler UK Metals places the estimated price of a kilo of copper from stripped cables at £8.20, and while opportunistic thieves aren’t likely to have the expertise needed to produce that at scale, more organised gangs can and do.

There’s also the very real threat of electrical theft. While it’s often the final few steps in homebuilding, white goods and boilers fetch hundreds of pounds on the black market, and thieves like those sentenced early last year capitalise on sites that lack the right security measures. 

3. Copper Piping & Metals

Closely tied to copper wiring and cables, the theft of copper pipes is a less pressing but no less concerning issue. It’s predominantly associated with property renovations and vacant commercial or domestic properties, particularly given that copper pipes are now largely replaced by PEX plastic piping.

However, as we’ve previously touched on, the price of copper is in a protracted uptick, and properties that do historically have copper piping as part of their construction (or have opted to use it for its durability and long-term value) face an increased threat from thieves.

We saw that in June of 2026, when two brazen thieves stole copper piping from a hospice undergoing refurbishment in Carlisle. While they’ve yet to be prosecuted at the time of writing, this isn’t likely to be a crime that wasn’t researched beforehand, especially given the rising value of braziery and heavy copper.

However, the cost of copper piping theft, while devastating for those who’ve lost, pales in comparison to wider statistics around metal theft. The British Metals Recycling Association (BMRA) estimated that metal theft costs the UK economy half a billion pounds, and north of £4.3 billion since 2013.

That’s largely perpetrated by organised gangs, of which the BMRA estimates to be around 60 that are currently active and stealing metal. Offences range from large-scale scrap heists to the stripping of lead from historic church roofs, but what they share is a predilection towards stealing those constituent metals like copper, lead and aluminium. 

It’s an epidemic, and one that the All-Party Parliamentary Group on Metal, Stone and Heritage are seeking to eliminate. Their Chair, MP Andrew Selous, points towards metal theft being “pervasive through society”, and that there’s a distinct “knowledge gap” on the true scale of the issue.

4. Roofing Slate & Tiles

Modern roofing is designed to fulfil multiple purposes. It’s both an insulator and a way to regulate heat, as well as being structurally integral and ideal for implementing modern energy-saving technologies like solar panels. But while there’s a range of reasons why contemporary roofs are a multi-purpose part of the building process, it’s those same reasons that make them an attractive prospect for criminals.

Roof tiles are expensive, and thieves are likely to be well aware of that value, even if they plan to sell them through non-legitimate means. While rooftop thefts themselves are rare, they can and do happen from both construction sites and from domestic properties undergoing renovations, like this case in the Cotswolds.

That purported value, alongside their aesthetic appeal and their large shipping quantities, also means that they’re a target on large-scale developments, as we saw with a recent attempted theft in Northumbria. This illustrates the risks of unsecured machinery and unattended materials on any site.

5. Scaffolding & Building Infrastructure

A common misconception for principal contractors is that their scaffolding is immune to theft. It’s easy to see why you’d think that – standards, ledgers, boards, base plates and transoms are all bulky materials and take a team to get set up, and aren’t the easiest to break down at the end of the project.

However, that doesn’t mean they’re not a target for opportunistic criminals or gangs who trade in scrap metal or scaffolding specifically. In fact, a renovation project in rural Caernarfon faced costly delays and a lengthy police investigation after large amounts of scaffolding were stolen during the demobilisation phase.

That’s far from an isolated example, however. This story from the Wirral illustrates the lengths scaffold thieves will go to, where two men masqueraded as site personnel to steal scaffolding as it was dismantled. Similarly, a block of flats in Stoke-on-Trent was targeted for the scaffolding in place for renovation works.

6. Vehicles & Catalytic Converters

Vehicle theft is a major concern, and one that’s remained consistently worrying over the last few years. While the latest report from the Office for National Statistics (ONS) points towards a 14% decline, there were still an estimated 596,000 separate recorded instances of vehicle theft.

While the data doesn’t break down how much of this theft occurred on construction sites, it’s still a major cause for concern, particularly given that so many contractors, tradespeople and labourers will use their own cars to get to and from the site. 

That doesn’t touch on vans and other road vehicles, which are so often a major target for thieves. The threat there is multi-pronged, with specialist insurers Kelliher Group estimating that around 75% of all tool thefts occur from vans or a tradesperson’s vehicle. The vans themselves are an equally appealing prospect for criminals, too.

Take this example from the Worcester Crematorium, where emboldened thieves stole both the van and its full contents of tools, to the value of an estimated £23,000. That’s not an isolated example, either, and while thieves do predominantly opt for the tools over the van (for ease of selling on), vehicles are far from safe.

That’s compounded by the presence of catalytic converters. While they’re no longer present on electric vehicles, the construction industry still relies heavily on more affordable, petrol or hybrid options, which do still have those specific components. It’s the presence of rare metals like platinum and palladium that makes them a major target for thieves who know what they’re doing.

Concerningly, the last 5 – 10 years have seen a major uptick in the amount of catalytic converters being stolen, with the BBC estimating that there were over 100,000 stolen between 2019 and 2022. While statistics seem to be petering out following concerted pushes from local and national police forces, it’s not an issue that the construction industry can afford to ignore.

7. Plant Machinery

The flipside to the more conventional vehicles you’ll see at your site, plant machinery like dozers, telehandlers and excavators are far from immune to the thefts we’ve pinpointed for road-going vehicles. With their place on large-scale construction projects essential, plant and heavy vehicle theft is a huge worry, especially for more rural sites.

Specialist insurers and investment company NFU Mutual bring the risk of rural crime into stark focus, with the estimated cost of telehandler theft alone in the region of £737,000.  It’s a must-have piece of kit for high-value energy projects that so often dominate rural construction.

It’s not just rural projects that are in danger, though. Stories like this from Wolverhampton in late 2025 point towards the fact that plant machinery represents a theft risk in its own right, not just as a source of fuel or parts. 

It’s thought that plant theft costs the UK industry over £1 billion annually, and that’s surged in recent years as plant and heavy machinery is outfitted with many of the modern conveniences we associate with our own vehicles.

Despite that cost, and its untold impacts on the construction industry, insurer Allianz estimates that only 10% of all plant equipment is ever recovered after it is stolen – another factor that criminals are well aware of.

How Do I Protect My Construction Site From Theft?

As an ACS Pacesetter company in the construction site security sector, we’d always advise blending more traditional measures (like Heras fencing and access controls) with the reassurance and deterrence offered by professional security services, such as solar-powered CCTV towers and VPOD, the visually-verified intruder alarm.

Here’s a brief overview of what we’d advise, and what can help lower insurance premiums and reinforce site security:

• Create a site security plan – A must-have under the CDM 2015 and as part of most large-scale builds, designing a bespoke construction site security plan is the first step towards building a package that’s unique to your project.
• Set up your perimeter – Already a legal stipulation of the Occupier’s Liability Act, you should create a complete perimeter for every phase of your site. That should include Heras fencing and gated/access-controlled entry, and could be augmented by AI-enhanced, digitised options like the ProEyez perimeter detection package.
• Monitor site visitor numbers – In the interests of preventing internal theft and mitigating the risks from subcontractors or sole traders, we’d advise having a system in place to monitor who is at your site and when. That might be a more high-tech solution (like signing-in applications) or a simple logbook.
• Invest in construction site security technology – Surveillance and monitoring are central to  protecting your onsite assets, people and property. That’s most readily facilitated through CCTV towers, which offer fully autonomous alerts, AI-assisted threat detection, and an immediate alert when an issue is detected.
• Implement manned guarding solutions – For high-risk, high-value projects (like the £10 billion Lower Thames Crossing), there’s little substitute for a responsive, intelligent human presence on your site. With mobile officer patrols, every aspect of your project is covered, with a trained, licensed response available whenever it’s needed.
