The RGII Domestic Gas Assessment (DGA) is the mandatory five-year competency reassessment for Registered Gas Installers (RGI) in Ireland. Open-book theory papers and practical tasks test six domains aligned with I.S. 813: combustion, pressure and flow, pipework, flues and ventilation, appliances, and electrical safety. RGIs may reassess up to six months before expiry. Our free prep includes 100 practice questions with explanations and an AI tutor.

1Under RGII rules, how often must a Registered Gas Installer (RGI) complete the Domestic Gas Assessment (DGA) competency reassessment?
A.Every 2 years
B.Every 3 years
C.Every 5 years
D.Every 10 years
Explanation: Section C 4.1.2 of the RGII Criteria Document and Section 10.2 of the Rules of Registration require every RGI to complete an accredited DGA at an approved assessment centre at least every five years. This periodic reassessment maintains registration and verifies continued domestic gas safety competence.
2Which official documents define the performance criteria for the Irish Domestic Gas Assessment (DGA)?
A.CER/15/080 (practical) and CER/15/081 (knowledge and understanding)
B.I.S. 813 Annex A and Annex B only
C.I.S. 10101:2020 and I.S. EN 1949
D.QQI 6N2053 and 6N2054 module descriptors
Explanation: RGII publishes the DGA criteria as CER/15/080 (Practical Assessment Performance Criteria) and CER/15/081 (Knowledge and Understanding Assessment Performance Criteria). Assessment centres design theory and practical tasks against these centrally approved criteria, which are based on I.S. 813 and related normative documents.
3Is formal retraining mandatory before an experienced RGI may sit the five-year DGA reassessment?
A.Yes — a minimum 16-day course is always required
B.No — training is optional, though many installers choose refresher courses before assessment
C.Yes — but only if the installer has not worked in gas for 12 months
D.No — the DGA is a self-certification form only
Explanation: The RGII Criteria Document states that RGIs are not required to undertake training prior to the DGA but may do so voluntarily. Accredited centres offer two- to three-day refresher courses, yet the legal requirement is successful completion of the open-book theory and practical assessment every five years.
4How far in advance of the DGA expiry date may an RGI complete reassessment while retaining the full five-year validity period?
A.Up to 1 month
B.Up to 3 months
C.Up to 6 months
D.Up to 12 months
Explanation: RGII guidance allows the DGA to be completed up to six months before the printed expiry date. When passed early, the new certificate still runs for the full five years from the original expiry date, giving installers flexibility to avoid last-minute suspension.
5What happens if an RGI allows their Domestic Gas Assessment (DGA) certificate to expire without renewal?
A.They receive a warning letter but may continue working for 30 days
B.Their RGII registration is suspended and they may not legally carry out designated domestic gas works
C.They may work provided a colleague cosigns Declarations of Conformance
D.They automatically transfer to provisional trainee status for one year
Explanation: A valid DGA competency certificate is a condition of RGII membership. Expiry without renewal leads to immediate suspension, which removes the legal authority to perform designated domestic gas works until reassessment is completed and the competency certificate is submitted to RGII.
6Which accreditation standard must certification bodies use when certifying DGA assessors and the competency scheme?
A.ISO 9001
B.ISO/IEC 17024
C.ISO 14001
D.ISO 45001
Explanation: DGA assessment centres must be certified by a body accredited to ISO/IEC 17024 (Conformity assessment — Requirements for bodies operating certification of persons). INAB accredits Irish certification bodies against this standard for the RGII competency scheme.
7What must a candidate present to an accredited assessment centre before commencing the DGA reassessment?
A.A letter from their employer confirming two years' experience
B.A current valid RGII identity card and registration number
C.A completed Safe Pass card only
D.A landlord gas safety certificate from the previous year
Explanation: Blueflame Certification scheme rules and RGII centre procedures require a current valid RGII identity card (or equivalent registration evidence) before DGA assessment. Reassessment candidates must also present their previous competency certificate and photographic ID.
8After successfully completing the DGA, what must the RGI submit to RGII to update their registration record?
A.A copy of the customer Declaration of Conformance Cert 1
B.The Personal Competency Certificate issued by the accredited certification body
C.A Gas Networks Ireland meter reading
D.An HSA incident report form
Explanation: RGII requires the Personal Competency Certificate from the accredited assessment centre to be sent promptly after a successful DGA. This updates the installer's registration file and confirms the next five-year reassessment date shown on the RGI identity card.
9The DGA knowledge assessment is described in RGII criteria as which type of examination format?
A.Closed-book, invigilated written exam only
B.Primarily open-book multiple-choice and written questions plus practical tasks
C.Online-only remote proctored test
D.Oral interview with CRU inspectors
Explanation: Criteria Document section C 4.4.2 defines the DGA as an open-book assessment consisting primarily of multiple-choice and written questions together with a practical assessment. Candidates may reference I.S. 813 and approved texts during the knowledge papers.
10How many practical competency areas are assessed in the Domestic Gas Safety Assessment (DGA) scheme?
A.4 competencies
B.5 competencies
C.6 competencies
D.8 competencies
Explanation: CER/13/273 and the updated DGA practical criteria assess six competencies: combustion and its control; pressure and flow; domestic pipework installations; flues and ventilation; domestic gas appliances; and electrical safety. Theory papers mirror these domains.
