Who Needs It
Who Needs This Course?
HSG47 requires anyone using cable and pipe locating equipment to be trained and assessed as competent. That applies to delegates using the equipment and to the duty holders responsible for safe management. In practice:
- ›Site delegates and groundworkers — anyone who picks up a CAT and Genny to locate utility services before excavations — the core audience. EUSR Category 1 course is the standard route.
- ›Civil engineers and site supervisors — responsible for supervising excavation work, interpreting utility drawings, and ensuring safe systems of work near utility services. ProQual CAT1 carries additional supervisor content.
- ›Utility workers and contractors — delegates working on or near buried utility services, pipes and infrastructure for utility companies, National Grid sites, highways authorities and network operators. EUSR registration is required by most clients.
- ›Duty holders and principal contractors — project managers, principal contractors and safety professionals have a legal duty to ensure their teams hold a current EUSR Category 1 or ProQual CAT1 card. National occupational standards apply across the team.
Most principal contractors and utility company permit systems require operatives to hold a recognised course certificate meeting the HSG47 Avoiding Danger competence standard — typically the EUSR Category 1 course (Locate Utility Services) or ProQual CAT1 — with the certificate’s expiry date in date before excavations begin.
Course Routes
What Does the Course Cover?
Two complementary areas: using cable avoidance tools and underground services detection devices to safely detect utility services, and managing safe excavation procedures around buried utility services. Sygma delivers each course at your premises UK-wide. Coverage includes utility drawings, line search documents, approved detection methods and the locate utility services HSG47 protocol before any dig begins. The course is safety critical for any work near buried services or on National Grid infrastructure.
CAT and Genny Training
Equipment operation and detection methodology
Cable locator (CAT) + signal generator (Genny) used to detect utility services before excavation. Cat genny equipment fundamentals, electromagnetic theory, all four detection modes, practical site assessment, and the Genny-First methodology that measurably reduces service strikes. Delegates also learn to use genny devices effectively as part of the detection process. Approved detection methods for locating buried utility services.
Available as EUSR Category 1, ProQual CAT1, or Sygma in-house course certification. CITB Approved course delivery.

Each delegate assessed against EUSR national occupational standards. Category 1 Locate Utility Services registration is processed on the completion date; 1 Locate Utility Services framework is the formal name on the card.
In-house EUSR Category 1 course dates available on request — pick a date that suits, up to 8 delegates per course at your premises, travel and EUSR registration included in the day rate.

Common Questions
Frequently Asked Questions
Is HSG47 training a legal requirement?
Not in the strict sense — HSG47 is HSE guidance, not legislation. The Health and Safety at Work Act 1974 and the Management of Health and Safety at Work Regulations 1999 require employers to ensure workers are trained and competent for the work they carry out. As HSG47 is the recognised industry standard for safe excavation near utility services, not providing this course creates a significant duty of care exposure. Most principal contractors and utility companies require evidence of an EUSR Category 1 or ProQual CAT1 course before allowing operatives to dig.
What is HSG47 training?
The collective term for any course meeting the competence requirements of the HSE guidance document 'HSG47: Avoiding Danger from Underground Services.' Covers cable avoidance tools used to locate utility services HSG47 standard before excavations begin, safe working procedures near buried utilities, and the duty holder obligations under national occupational standards. In practice this means a course fulfilling the HSG47 competence standard — typically the EUSR Category 1 course (formally Utility Excavations Category 1 Locate Utility Services), ProQual CAT1, or an equivalent assessed course from a CITB Approved Training Organisation.
How long is the course?
One or two days, depending on format and accreditation route. The one-day course covers theory plus the written and practical assessment required. Two-day course formats add depth to the practical element or incorporate a second accreditation assessment. EUSR Category 1 and ProQual CAT1 courses both run as either one-day or two-day programmes. For complete beginners, the two-day course is recommended. Course dates available to suit your team — registration via the contact form.
What certificate do you get from the course?
Delegates receive the EUSR Category 1 card — formally the Utility Excavations Category 1 Locate Utility Services qualification — on the most widely recognised accreditation route. Issued by the Energy and Utility Skills Register following course completion and EUSR registration, valid for three years (expiry date printed on the card), recognised across UK construction, utilities, HV substations and highways sectors. ProQual CAT1 is an alternative accredited course that produces a three-year assessed certificate with its own expiry date. Sygma also issues an in-house certificate of completion for companies that do not require an awarding body card. All certificates are backed by written and practical assessment records.
How much does the course cost?
Priced as an in-house day rate for up to 8 delegates at your premises, or per person on open course dates. Travel is included with no hidden extras. The course cost varies by format — EUSR Category 1 and ProQual CAT1 carry additional awarding body fees plus EUSR registration. CITB levy-paying employers may be eligible for funding support through the CITB Employer Network. Contact Sygma for a tailored quote with available course dates.
Does the certificate need to be renewed?
Yes. EUSR Category 1 and ProQual CAT1 certificates expire after three years and must be renewed before the expiry date. Most principal contractors and utility companies will not permit delegates on site once a certificate has lapsed. Renewal involves a refresher course and reassessment, then EUSR registration is updated and a new card issued with a fresh expiry date. Sygma recommends booking renewal in the three months before your current registration ends.
