Added supplementary examination pathways for gas installer apprentices from related trades
The regulation now permits apprentices who have completed final exams in related trades (water pipe installer, coppersmith, mechanic, pipe fitter, locksmith, roofer, or central heating installer) to take a supplementary examination to qualify as a gas installer. Supplementary exam requirements and procedures are now defined.
What changed
A new section (§ 5) was added establishing supplementary examination (Zusatzprüfung) procedures. Apprentices completing final exams in water pipe installation may take a supplementary exam covering only the 'Expert discussion' subject. Apprentices from six other trades (coppersmith, mechanic, pipe fitter, locksmith, roofer, central heating installer) may take a supplementary exam covering both 'Test work' and 'Expert discussion'. Additionally, a minor spelling correction was made ('miteinzubeziehen' to 'mit einzubeziehen'); the last-updated metadata was refreshed to 2 June 2026; and subject classification '50/04 Vocational training' was added.
Who is affected
Apprentices who have successfully completed final exams in water pipe installation or the six named trades may now pursue gas installer qualification through a supplementary examination rather than a full final exam. Examination boards and vocational training providers administering these exams are also affected.
What to look out for
The supplementary exam requirements differ by trade: water pipe installers face a lighter requirement (expert discussion only), while other trades must complete both test work and expert discussion. The procedural rules governing these supplementary exams are incorporated by reference from the main final exam regulations (§ 2), so applicants should review those rules carefully.
