Proven Record in Reducing Strikes and Increasing Genny Usage
21 Years. A Proven Record in Reducing Utility Strikes and Raising Competence on Site.
Since 2004, Sygma has delivered underground utility location and avoidance training to some of the UK's largest infrastructure and utilities contractors. Not as a module in a broader programme. Not with freelance trainers hired per course. As a dedicated specialist with directly employed staff, one subject, and results that clients can measure on site.
Clients who implement our Genny-First methodology report a 70 to 80% measurable increase in Genny usage among trained operatives. That is not a delegate satisfaction score. That is fewer strikes, every working day.

Why Independence Matters
We have no surveys to sell. No equipment to push. No agenda beyond building the most competent utility location teams in the industry. After 21 years, it is still all we do. When we tell you something is wrong, we have no financial reason to soften that verdict.
The Safety Case
Why Cable Avoidance Training Matters
Thousands of underground utility strikes are reported across Great Britain every year. Some result in serious injury. Some are fatal. Accidental contact with high-voltage electricity cables can cause electrocution, fire, and severe burns. Hitting a gas main risks explosion. These are not edge cases. They are the reason cable avoidance training exists.
Cable avoidance training teaches operatives and supervisors to locate, identify, and avoid buried pipes, cables, and communication lines before any excavation begins. Using a CAT and Genny together, trained operators can detect live cables in Power Mode, trace metallic pipes in Radio Mode, and apply a known signal to a specific conductor in Genny Mode for accurate tracing. The result is faster, safer digging with fewer stoppages, fewer strikes, and fewer of the expensive repair costs and project delays that come with hitting a service.
Under HSG47 and the CDM Regulations, employers have a legal duty to ensure excavation workers are properly trained in cable avoidance. That includes obtaining utility plans before work starts, conducting site inspections, completing a risk assessment, and verifying the location and depth of services by digging trial holes by hand before using mechanical plant. Failure to meet these responsibilities can result in prosecution, significant fines, and in the worst cases, criminal liability.
Every Sygma cable avoidance training course covers these legal requirements alongside full practical training on CAT and Genny equipment. Our trainers are directly employed, TAQA qualified, and experienced in utility surveying and mapping. The knowledge your operatives gain ensures a safer working environment and compliance with the legal standards that apply to every excavation project in the UK.
Accreditation Routes
Choosing the Right CAT and Genny Qualification
Not all CAT and Genny training courses lead to the same qualification, and the differences matter. There are several accreditation routes available in the UK, each with different assessment methods, certification periods, and industry recognition. Understanding which route is right for your workforce is one of the most important decisions you will make.
The EUSR Energy and Utilities Skills (EUS) route is the most common accreditation in the energy and utilities sector. EUS CAT1 is widely mandated by utility companies and their supply chains. It uses a multiple-choice assessment and practical test. Certification is registered on the EUSR database and is typically required for EUSR card renewal.
ProQual CAT1 is a more comprehensive qualification. It covers CDM Regulations, risk assessment monitoring, and Safe Systems of Work aligned with HASAWA, HSG47, and GS6. Where EUS uses multiple-choice questions, ProQual requires written theory papers and assesses both theory and practical skills across most criteria. Sygma helped develop the ProQual CAT1 standard because the industry needed a qualification that matched the depth of competence required on site.
NPORS is another recognised certification route. Most industry accredited CAT and Genny certifications, including NPORS, are valid for three to five years before refresher training is required. Non-accredited courses also exist. These typically include a multiple-choice test and practical assessment, with a certificate valid for three years. Some providers run non-accredited CAT and Genny training as a half day course. Sygma does not. Our minimum for any cable avoidance training course is a full day, because we believe competence cannot be built in four hours.
Whichever accreditation route your organisation requires, Sygma delivers the full range of CAT and Genny training courses. As an independent provider with no manufacturer ties, we focus entirely on building competence rather than meeting a minimum standard.
Why It Matters
The Sygma Standard
Other training companies deliver hundreds of different subjects. Sygma delivers one. Underground utility location and avoidance is not part of what we do. It is all we do. Every trainer is an experienced utility mapping professional. We are not tied to any manufacturer and we do not sell EM equipment. That is what makes our training different.
21 Years. One Specialism.
We have been delivering underground utility location training since 2004. It is the only thing we do. That focus produces a depth of expertise that generalist providers cannot replicate.
100% Independent. Zero Manufacturer Ties.
We only teach one subject. We are not tied to any equipment manufacturer and we do not sell EM equipment. Because we are independent, our trainers can make recommendations based on what actually works, not on how a distributor makes a margin.
Genny First. Always.
Clients who implement our Genny-First methodology report a 70 to 80% measurable increase in Genny usage among trained operatives on live sites. That is not a training statistic. That is a site that is measurably safer.

Talk to UsThe Genny Principle
Why We Teach the Genny Before the CAT
The Genny applies a known signal to a specific conductor. The CAT then finds that signal. Together, they are significantly more reliable than passive detection alone. But most operatives on UK sites reach for the CAT and never connect the Genny.
Sygma's training starts with the Genny because that is where strike prevention actually begins. Clients who implement our Genny-First methodology report a 70 to 80% measurable increase in Genny usage. That is not a training statistic. That is a site that is measurably safer, every single day.

Common Questions
Frequently Asked Questions
What is underground utility location training?
Underground utility location training teaches operatives and supervisors how to locate and avoid buried services before and during excavation. It covers electromagnetic signal principles, Genny & CAT operation, safe digging practice, and the legal and procedural framework under HSG47.
What accreditations does Sygma Solutions hold?
Sygma Solutions is a CITB Approved Training Organisation, an accredited ProQual centre, a registered EUSR/EUS provider, a TSA Approved Training Provider, and a CICES recognised provider.
How much does cable avoidance training cost?
Sygma charges per course, not per person. Whether you send 4 delegates or 8, the course fee stays the same. Travel within the UK mainland is included. There are no hidden fees beyond the awarding body accreditation charge where applicable. Contact us for a quote.
Do you offer CITB-funded training?
Yes. Sygma is a CITB Approved Training Organisation. CITB-registered employers may be able to access funding through the CITB Employer Network scheme. Funding availability and amount varies. Contact your CITB Employer Network adviser directly to discuss your eligibility.
Can you deliver training on-site at our premises?
Yes. Most Sygma courses can be delivered at your site, yard, or offices anywhere on the UK mainland. Travel is included in the course fee. We require a suitable indoor space and outdoor practice area.
What is the difference between EUS CAT1 and ProQual CAT1?
They are not equivalent. ProQual CAT1 is significantly more thorough. It covers topics EUS does not assess at all, including CDM Regulations, risk assessment monitoring, and Safe Systems of Work aligned with HASAWA, HSG47, and GS6. Where EUS relies on multiple choice questions, ProQual uses written theory papers and requires both theory and practical assessment across most criteria. In 21 years of delivering utility avoidance training, the ProQual CAT1 is the only qualification Sygma does not have to add content to, because we helped develop it to the standard the industry actually needs. EUS CAT1 is required where your client mandates EUSR registration.
What equipment is used on Sygma cable avoidance training courses?
Sygma training covers a range of manufacturer equipment including Radiodetection CAT4, CAT4+, RD8200, and RD8100, Vivax-Metrotech vLoc, and Leica DSX. We are fully independent and not tied to any single equipment manufacturer. Our trainers teach operatives to use CAT and Genny tools across all four locating modes: Power, Radio, Genny, and Avoidance. Training covers manufacturer specific knowledge and general awareness of utility services so that skills apply on site regardless of which equipment your organisation uses.
Is cable avoidance training a legal requirement?
HSG47 and the CDM Regulations place a duty on employers to ensure that anyone involved in excavation work is competent in avoiding underground services. While there is no single law that says you must hold a specific CAT and Genny certificate, the legal framework requires employers to demonstrate that their workforce has been properly trained. In practice, most principal contractors and utility companies require a recognised cable avoidance training qualification such as EUS CAT1 or ProQual CAT1 before allowing operatives on site. Failure to provide adequate training can result in enforcement action, fines, and criminal prosecution if a cable strike leads to injury.
