The potential dangers of working near underground services is one of the key risk factors for anyone engaged in utility activities.
Pipe and cable locators offer an effective way to locate buried electrical lines and conduit. Locators should be used to trace services and get an accurate picture of where services are laid underground. The locator scan is used to trace the line of any live pipe or cable and to confirm the location and depth.
This qualification will provide candidates with the knowledge and skills to safely locate buried services and provides advice and instruction on how to reduce the risks.
For the successful completion of the qualification, candidates must complete an end of course practical assessment or knowledge test that measures the learning outcomes and has a pass or fail criteria.

Candidates must demonstrate the level of knowledge described in the unit. Assessment is the process of measuring a candidate’s knowledge and understanding against the standards set in the qualification.
Each candidate is required to produce evidence which demonstrates their achievement of all of the learning outcomes and assessment criteria for each unit.
Evidence can include: assignments/projects/reports; worksheets; portfolio of evidence; record of oral and/or written questioning; candidate test papers
Learning outcomes set out what a candidate is expected to know, understand or be able to do.
Assessment criteria specify the standard a candidate must meet to show the learning outcome has been achieved.
Summary – Award
Candidates who achieve the requirements for qualifications will be awarded:
- A certificate listing the unit achieved, and
- A certificate giving the full qualification title – ProQual Level 2 Award in Utility Avoidance and the Location of Buried Services in Construction
