What is Tool Marking?

A Complete Guide for UK Tradespeople and Businesses

Tool Marking Explained

Tool marking is the process of identifying and tagging your tools and equipment with a unique mark or code, making them traceable if lost or stolen. It’s one of the most effective theft prevention methods recommended by UK police forces, including the Metropolitan Police and the National Business Crime Centre.

At SelectaDNA, we specialise in forensic tool marking solutions that give your tools a unique DNA identity, helping you protect your livelihood, meet insurance requirements, and increase recovery chances in case of theft.

Why Mark Your Tools?

Deter thieves: Marked tools are harder to sell on and more likely to be avoided.
Aid recovery: Police can identify and return your stolen tools faster.
Prove ownership: Essential for insurance claims and disputes.
Comply with insurance policies: Many insurers now recommend or require tool marking.

“Marking your tools with SelectaDNA is one of the simplest ways to prevent theft and help police trace stolen goods.”

How Does Tool Marking Work?

Tool marking can be carried out in several ways, including:

1. Forensic DNA Marking (Recommended)

Using a SelectaDNA kit, you apply a clear liquid containing a unique DNA code and microdots to each tool. This code is registered to you and can be read by police using UV light and a microscope.

2. Engraving or Etching

Marking tools with initials, a postcode, or company name using engraving tools. While helpful, these marks can be removed or altered more easily than forensic DNA.

3. QR Codes & Labels

Applying tamper-proof labels with scannable codes linked to a registration system. For maximum security, we recommend combining forensic DNA with tamper-resistant labels, both available in the SelectaDNA Tools and Equipment Kit.

Where Should You Mark Tools?

For best results, apply marking in multiple locations on each tool, especially in hidden or hard-to-reach areas. This increases the chances of detection and prevents easy removal. Here's a walk-through of the process:

Ideal items to mark include:

Power tools (drills, saws, grinders)
Hand tools (spanners, pliers, hammers)
Toolboxes and cases
Ladders and access equipment
Site generators and compressors
