What the Course Entails and Exam Details

This rigorous qualification is designed to assess your ability to meet the requirements set out by current environmental legislation regarding the handling and containment of regulated gases. The syllabus is exhaustive, combining deep theoretical understanding with mandatory hands-on technical proficiency. The core subjects covered include:

• The environmental impact of ozone depletion and global warming potentials (GWP).

• The thermodynamic principles of the vapour compression cycle and RACHP systems.

• Identifying key system components, their functions, and potential leakage points.

• Safe handling practices for different refrigerant types and safe working environments.

• Fabricating mechanical and brazed joints on copper pipework.

• Performing critical system processes, including pressure testing, evacuation, and dehydration to industry standards.

• Executing precise refrigerant charging of blended and pure gases.

• Implementing direct and indirect leak detection methods on active systems.

• Legally compliant record keeping, maintenance of logbooks, and waste disposal protocols.

While multiple categories of this award exist (e.g., Category I for all system sizes, Category II for smaller charges), the goal is always to prove you are a competent person as defined by the regulations.

What to Expect in the Final Exam

Achieving this qualification requires you to prove competence through a structured two-part final assessment. It is essential to recognize that both components must be passed within a specified timeframe to receive the award. Here is what you must prepare for:

• Theory Assessment: You will first take a closed-book, multiple-choice online knowledge test, known as a GOLA (Global Online Assessment) exam. This test typically consists of 40 questions and has a set time limit, often around 80 minutes. The pass mark is strict and reflects the need for accurate regulatory knowledge.

• Practical Assessment: This is the most demanding aspect of the qualification. You must undertake a timed practical exam, observed and scored by a certified assessor. This timed assessment, which can range from two to four hours depending on the category, requires you to perform crucial tasks such as fabrication, brazing, leak testing, system recovery, and charging accurately and efficiently without prompt.

• Requirements: A successful outcome means demonstrating 100% safety and technical correctness throughout the practical phase. You must arrive prepared with correct PPE and understand that failure to pass any mandatory practical unit results in an overall fail for the practical assessment.

How to Study and Exam Centers

Preparation is paramount for the F-Gas (2079) Award. To ensure success, follow these actionable strategies:

• Attend a Dedicated Training Course: We strongly advise enrolling in a leading, specialized training provider for a multi-day course before your exam. These courses provide mandatory workshop practice time, which is essential for mastering the fabrication and pressure testing requirements.

• Study Regulatory Guides: Immerse yourself in the actual F-Gas regulations (e.g., EU 517/2014 and UK equivalents) and standard refrigeration textbooks. Understand the specific leak-check intervals based on system charge size and the rules for charging blended refrigerants in the liquid state.

• Use Practice Tests: Utilize professional City & Guilds 2079 practice exams and mock papers to familiarize yourself with the phrasing of multiple-choice questions. This will identify knowledge gaps and boost your confidence.

• Locating Exam Centers: You cannot take this entire assessment online from home. Due to the practical nature of the test, you must attend a City & Guilds validated center or approved commercial training provider that possesses the specialized workshop facilities and equipment required for RACHP training and assessment. These centers are located throughout the UK and are the standard location for technical, trade-based awards. Look for centers listed on the official City & Guilds website or contact leading vocational colleges.
