About This Course
What Is the ProQual CAT1?
The ProQual CAT1 is a ProQual-accredited cable avoidance qualification and the most rigorous one-day Genny & CAT course available in the UK. Delegates must demonstrate competence against 14 theory criteria and 8 practical criteria before a certificate is issued. It is accredited by ProQual Accreditations and externally audited to ensure assessment standards are maintained. It sits alongside the EUSR CAT1 as an alternative accreditation route for operatives working near buried services.
Unlike pass-or-fail percentage tests, the ProQual CAT1 uses a criteria-based competency assessment. Every single criterion must be met. This makes it the preferred qualification for organisations with the most demanding procurement and H&S frameworks, including those governed by CDM Regulations.
Sygma delivers this qualification at our Wigan HQ, at The Survey School in Worcester, or on-site anywhere in the UK. All four locating modes (Power, Radio, Genny, and Avoidance) are demonstrated and assessed hands-on, along with every Genny signal application method: direct connection, clamp, capacitance, induction, and nulling out.
Clients who implement Sygma's ProQual CAT1 training as part of a wider competency programme report measurable reductions in cable strikes and service damage. Our Genny-First methodology, which is central to how we deliver this course, drives a 70 to 80% increase in Genny usage across trained teams. That is a behavioural change that shows up in locator data downloads, not just in assessment results.
The Only Qualification We Do Not Have to Add To
In 21 years of delivering utility avoidance training, Sygma has had to add content to every qualification on the market to make it fit for the real demands of the industry. Every single one. The ProQual CAT1 is the first qualification we have developed in partnership with an awarding body that covers everything needed from a course in this subject. It is the only qualification we deliver where we do not have to supplement the syllabus, because the syllabus was built to the standard the industry actually needs.
Developed by the Industry's Leading Experts
Built by Sygma Solutions and CSTA in Partnership with ProQual
Sygma Solutions, along with CSTA (both recognised as the leading experts in utility location in the UK), specifically developed this qualification in partnership with ProQual. It was not adapted from an existing framework or reverse-engineered from a spec sheet. It was built from the ground up by people who have spent decades locating, training, assessing and investigating service strikes.
That is why the ProQual CAT1 is the only qualification Sygma does not have to add content to. Every other qualification on the market requires additional material to bring it up to the standard the industry actually needs. The ProQual CAT1 was written to that standard from day one.
No other training provider can make this claim. No other qualification has this development pedigree. When you book a ProQual CAT1 with Sygma, you are getting the qualification delivered by the people who built it.

Core Principle
Verification, Not Assumption
The ProQual CAT1 is built around a single principle: verify, do not assume. Every theory criterion and every practical criterion exists to test whether the delegate can prove what is in the ground before work begins, rather than relying on plans, habit, or guesswork.
This is what separates ProQual from a pass/fail percentage test. A percentage-based assessment allows a delegate to get several answers wrong and still pass. The ProQual model does not. If a delegate cannot demonstrate a criterion, they do not receive a certificate for that criterion. There is no margin for error on the things that matter most.
In practice, this means every delegate who holds a ProQual CAT1 has been individually verified against every area of the qualification. The assessor has observed their theory knowledge and their practical performance, criterion by criterion. That is a level of confidence that a percentage score cannot provide.

| Ref | Criterion |
|---|---|
| P1 | Determine the work location using company documentation and work instructions (ensure site plans obtained, recognise plan references and symbols, state action required if plans unavailable) |

Acceptance
Who Accepts ProQual CAT1?
The ProQual CAT1 is widely accepted across the utility, construction, and infrastructure sectors. Some organisations mandate it specifically because it exceeds the minimum standard set by EUSR. Others accept it alongside EUSR as an equivalent or preferred route.
Tier 1 and Tier 2 Contractors
ProQual CAT1 is accepted by principal contractors operating under CDM duty-holder obligations. Multiple Tier 1 and Tier 2 contractors have adopted ProQual-accredited training as part of their competency frameworks.
Water, Gas and Electricity Utilities
Water companies, gas distribution networks, and electricity network operators accept ProQual CAT1 as evidence of competency for teams working near their buried infrastructure.
Multi-Utility and Infrastructure
Organisations managing multi-utility sites, highway works, and new-build infrastructure accept ProQual alongside or in place of EUSR for cable avoidance competence.
Organisations Requiring CDM Coverage
The ProQual CAT1 is the only cable avoidance qualification that includes CDM Regulations in its theory assessment. For organisations operating as principal designers or principal contractors, this is a significant compliance advantage.

FAQs
Frequently Asked Questions
What is the difference between ProQual CAT1 and EUSR CAT1?
They are not equivalent qualifications. ProQual CAT1 is significantly more thorough. It covers topics that EUSR does not assess at all, including CDM Regulations, risk assessment monitoring and reporting, and Safe Systems of Work aligned with HASAWA, HSG47, and GS6. Where EUSR relies on multiple choice questions, ProQual uses written theory papers that require candidates to demonstrate understanding in their own words. ProQual also requires both theory and practical assessment across most criteria, whereas EUSR covers many areas through MCQ alone with no practical demonstration. In 21 years, Sygma has had to add content to every qualification on the market to make it fit for industry. The ProQual CAT1 is the only one we do not have to add anything to, because it covers everything needed. If your procurement framework gives you a choice, ProQual CAT1 delivers a measurably higher standard.
Why does the ProQual have no percentage pass mark?
The ProQual framework uses a competency-based assessment model. Rather than scoring a percentage on a multiple-choice paper, the assessor observes the delegate and judges whether each individual criterion has been met. Every criterion must be met before a certificate is issued. This is considered a more robust demonstration of real-world competence.
Do I need to bring my own CAT and Genny?
For classroom-based sessions at Wigan or Worcester, Sygma provides all equipment (Radiodetection CAT4 and Genny4 as standard). This course can be delivered on any of the following equipment: Radiodetection CAT4, CAT4+, RD8200, RD8100, Vivax-Metrotech vLoc, or Leica DSX. For on-site delivery, the client must supply a locator and signal generator for the practical assessment elements. The equipment must be calibrated and in working order.
What happens if a delegate fails one of the practical criteria?
If a delegate does not meet a criterion during the assessment, the trainer will note the gap and, where time allows, provide additional coaching before a reassessment. If competence cannot be demonstrated on the day, the delegate will not receive a certificate and will need to attend a further session.
Is ProQual CAT1 training recognised on utility and construction sites?
Yes. The ProQual CAT1 is widely accepted across utility, water, gas, electricity, and construction sectors. Some organisations specify ProQual; others specify EUSR. If you are unsure what your framework requires, contact us and we will check for you.
What are the progression routes from ProQual CAT1?
Delegates who hold the ProQual CAT1 can progress to the ProQual CAT1 Plus (additional theory and extended practical criteria), the ProQual CAT2 Safe Dig qualification, or the OSCA scheme. Sygma can advise on the right progression route for your team.
