The QQI Level 5 F-Gas Category I certificate is Ireland's full-scope qualification for handling fluorinated greenhouse gases on stationary refrigeration, air-conditioning and heat-pump equipment of any size. It meets EU Regulation 517/2014 (S.I. 658 of 2016) and Commission Implementing Regulation 2015/2067, authorising installation, servicing, repair, decommissioning, leak checking and recovery without charge-size limits. Programmes require approximately 100 learning hours and assess both a theory examination and a practical skills demonstration at an approved provider. Candidates typically need a refrigeration and air-conditioning trade qualification or apprenticeship. Company certification is administered separately by F-Gas Registration Ltd. This free prep includes 100 research-based practice questions with explanations and an AI tutor.

1Under EU Regulation 517/2014 (as transposed in Ireland by S.I. 658 of 2016), what is the scope of F-Gas Category I certification in Ireland?
A.All installation, maintenance, servicing, repair, decommissioning, leak checking and recovery activities on stationary refrigeration and air-conditioning equipment of any charge size
B.Leak checking only on hermetically sealed systems under 3 kg without breaking the circuit
C.Recovery of refrigerant from small hermetically sealed systems only
D.Installation of split air-conditioning units under 6 kg charge only
Explanation: Category I is the full-scope certificate under Commission Implementing Regulation (EU) 2015/2067. It authorises personnel certified by F-Gas Registration Ltd (following QQI Level 5 assessment) to perform all regulated F-gas activities on stationary RAC equipment regardless of system size.
2Which Irish statutory instrument gives domestic legal effect to EU F-Gas obligations for stationary equipment in Ireland?
A.S.I. 658 of 2016 (European Union (Fluorinated Greenhouse Gas) Regulations 2016)
B.S.I. 542 of 2010 (Environmental Protection Agency Act)
C.S.I. 312 of 2019 (Climate Action and Low Carbon Development)
D.S.I. 101 of 2008 (Waste Management Regulations)
Explanation: S.I. 658 of 2016 transposes Regulation (EU) No 517/2014 into Irish law. It sets operator duties, certification requirements, leak-check intervals, record keeping and enforcement provisions enforced by the EPA.
3In Ireland, who is the competent authority responsible for enforcing F-Gas Regulation requirements on stationary equipment?
A.The Environmental Protection Agency (EPA)
B.The Health and Safety Authority (HSA) only
C.F-Gas Registration Ltd
D.Quality and Qualifications Ireland (QQI)
Explanation: The EPA is Ireland's competent authority under S.I. 658 of 2016 for monitoring compliance, investigating breaches and applying penalties. F-Gas Registration Ltd administers the company certification scheme; QQI accredits the training standard.
4What educational qualification underpins personal F-Gas certification in Ireland before registration with F-Gas Registration Ltd?
A.QQI Level 5 Special Purpose Certificate in F-gas Handling in Large RACHPT&T Systems Category I (or the equivalent Category II–IV award)
B.QQI Level 3 Certificate in Plumbing and Heating
C.A City & Guilds 2079 Level 2 certificate alone without Irish registration
D.An EPA environmental officer licence
Explanation: Technicians must complete the relevant QQI Level 5 Special Purpose Certificate (e.g. F-gas Handling in Large RACHPT&T Systems Category I) covering theory and practical assessment aligned with the Category I-IV scopes in Commission Implementing Regulation (EU) 2015/2067 Annex I. Successful candidates are then registered by F-Gas Registration Ltd on the national company/personnel register.
5From 1 January 2021, which statement about UK F-Gas personnel certificates is correct for work in Ireland?
A.UK-issued F-Gas personnel certificates are no longer recognised for work in Ireland; Irish QQI-based certification is required
B.UK certificates remain fully equivalent if the technician also holds a Safe Pass card
C.UK certificates are valid only for systems under 3 kg charge
D.UK certificates are recognised provided the company is registered in Northern Ireland
Explanation: Following Brexit, Ireland ceased mutual recognition of UK F-Gas personnel certification from 1 January 2021. Technicians working in Ireland must hold certification through F-Gas Registration Ltd based on the QQI Level 5 programme.
6What is the primary role of F-Gas Registration Ltd in the Irish F-Gas regime?
A.To certify F-Gas companies and register certified personnel who may legally work on equipment containing fluorinated gases
B.To set HFC import quotas for the Irish market
C.To conduct mandatory EPA leak inspections on all RAC plant
D.To approve new refrigerant blends for sale in the EU
Explanation: F-Gas Registration Ltd operates the company certification scheme required before undertaking regulated F-gas work in Ireland. It maintains the register of certified companies and personnel and verifies training against QQI standards.
7Under F-Gas Category II certification in Ireland, on which equipment may a technician perform maintenance, servicing, repair, decommissioning and recovery that entails breaking into the refrigerant circuit?
A.Equipment containing less than 3 kg of fluorinated refrigerant, or less than 6 kg if the system is hermetically sealed
B.Any stationary system regardless of charge size
C.Mobile air-conditioning in road vehicles only
D.Equipment over 500 tonnes CO2 equivalent only
Explanation: Under Commission Implementing Regulation (EU) 2015/2067 Article 2, Category II authorises installation-adjacent maintenance, servicing, repair, decommissioning and recovery (circuit-breaking activities) only on small systems: under 3 kg charge, or under 6 kg where the equipment is hermetically sealed and labelled. Unlike these activities, Category II's leak-checking authorisation is limited to non-invasive methods that do not entail breaking into the circuit — the same restriction that applies under Category IV — regardless of equipment size.
8What activities are permitted under F-Gas Category III certification in Ireland?
A.Recovery of fluorinated refrigerant from small systems only
B.Full installation and commissioning of commercial chillers
C.Leak checking without breaking the refrigerant circuit only
D.Design of VRF systems and load calculations only
Explanation: Category III is limited to recovery operations on small equipment. It does not authorise charging, installation, or leak checking that involves breaking into the circuit on larger systems.
9Under Category IV certification, a technician in Ireland may legally perform which activity?
A.Leak checking without breaking the refrigerant circuit
B.Recovery and recycling of refrigerant from any system size
C.Brazing new pipework on a split system during first fix installation
D.Pressure strength testing with nitrogen on a new circuit
Explanation: Category IV authorises only non-invasive leak detection methods that do not break the refrigerant circuit (e.g. electronic detectors at accessible points, indirect monitoring). Any work opening the circuit requires a higher category.
10Which operator duty under Regulation 517/2014 must the owner of F-gas equipment ensure is met in Ireland?
A.Prevent deliberate release of F-gases, use certified personnel, maintain leak-check records and ensure proper recovery at end of life
B.Replace all HFC systems with CO2 within two years of installation
C.Publish annual refrigerant inventories on the company website
D.Employ an EPA inspector on site for every service visit
Explanation: Operators (owners/controllers of equipment) must prevent venting, use certified companies/personnel for regulated work, comply with leak-check schedules, label equipment and keep records of gas quantities and service activities.
