Bundesagentur für Arbeit, Entgeltatlas — Anlagenmechaniker/in Sanitär-, Heizungs- und Klimatechnik (Anforderungsniveau: Fachkraft; median 3.884 EUR/month; lower quartile 3.303 EUR; upper quartile 4.500 EUR; full-time gross, Deutschland, Datenstand: Entgeltatlas 2025). Annual figures are the monthly values x12.

Time to qualify

2.5–4 years

3.5 years for the standard dual Ausbildung to Anlagenmechaniker/in SHK — on-the-job training in a Handwerksbetrieb plus Berufsschule, with the gestreckte Gesellenprüfung split into Teil 1 after 18 months (30% weighting, hand-tool basics, pipe joints, measurement) and Teil 2 at the end (70%, including a 15-hour practical customer task). Good school leavers (Mittlere Reife, Fachabitur or Abitur) can apply with their employer to shorten it by 6–12 months. Progressing to Installateur- und Heizungsbauermeister/in (the Meisterbrief needed to run your own business) typically adds several years of work experience plus a part-time or full-time Meisterschule.

Cost to qualify

€0 – €10,690

The Ausbildung is paid, not paid for: regional Handwerkskammer tariffs (e.g. Handwerkskammer für Ostthüringen, effective 1 January 2026) list training pay of about €950/month in year one rising to about €1,100/month by year four, though exact figures vary by Bundesland and collective agreement (Baden-Württemberg's 2025 tariff runs €1,090–€1,390 across the training period). Berufsschule is free and the Gesellenprüfung fee is modest, so out-of-pocket cost to qualify as a journeyman (Geselle/in) is essentially zero. The figure shown applies to the optional later upgrade: the Installateur- und Heizungsbauermeister/in course (Teile I and II, about 1,100 hours) costs roughly €6,420–€10,690 depending on provider, with Aufstiegs-BAföG (AFBG) state funding and KfW loan entitlement available toward it.

How to become a Plumber — step by step

1. 1

   Finish school and secure an Ausbildung contract 3–9 months of applying

   There is no fixed certificate requirement, but a Hauptschulabschluss or Mittlere Reife is typical. Apply directly to SHK Handwerksbetriebe (plumbing/heating firms) for an Ausbildungsplatz — with more than 12,000 SHK positions unfilled nationally, motivated applicants have strong odds.

2. 2

   Start the dual Ausbildung First 18 months

   Split your time between on-the-job training in the Handwerksbetrieb and Berufsschule, covering pipework, heating systems, ventilation, hydraulics and electrics basics.

3. 3

   Sit Gesellenprüfung Teil 1 After 18 months

   The first, lower-weighted exam segment (30% of the final grade), covering hand-tool basics, pipe joints and measurement techniques.

4. 4

   Continue specialising and complete the Ausbildung Remaining ~2 years

   Deepen skills across sanitary, heating and climate-technology systems, including modern heat pump and renewable heating installation.

5. 5

   Sit Gesellenprüfung Teil 2 End of Ausbildung

   The larger, 70%-weighted exam segment at the end of training, including a 15-hour practical customer job (Kundenauftrag) that forms the centrepiece of the assessment.

6. 6

   Work as a qualified Geselle/in Ongoing

   Once you pass, you can work as an employed Anlagenmechaniker/in SHK without further licensing. Many stay employed for years, building experience and pay.

7. 7

   Optionally pursue the Meisterbrief Several years' experience plus 1–2 years part-time or several months full-time study

   To run your own SHK business or formally train apprentices, complete an Installateur- und Heizungsbauermeister/in course (Teile I and II, about 1,100 hours) and pass the Meisterprüfung.

Requirements to be a Plumber

• Ausbildung to Anlagenmechaniker/in Sanitär-, Heizungs- und Klimatechnik (3.5-year dual programme)educationRequired

  The standard qualifying route: a federally regulated, 3.5-year dual Ausbildung combining paid work in a Handwerksbetrieb with Berufsschule. There is no university requirement.

• Gestreckte Gesellenprüfung (Handwerkskammer journeyman exam)licenseRequired

  Administered by the regional Handwerkskammer (or the IHK for apprentices trained in an industrial rather than craft business). Split into Teil 1 (after 18 months, 30% of the grade) and Teil 2 (at the end, 70%, including a 15-hour practical customer job). Passing confers the Geselle/in title, which is what employers require; there is no separate state licence to work as an employee.

• School-leaving certificate (Schulabschluss)educationOptional

  No specific certificate is legally mandated. In practice firms hire mostly applicants with Hauptschulabschluss or Mittlere Reife; a stronger certificate (Mittlere Reife, Fachabitur or Abitur) also lets you apply to shorten the Ausbildung by 6–12 months.

• Meisterbrief (Installateur- und Heizungsbauermeister/in)licenseOptional

  Installateur und Heizungsbauer is item 24 of Anlage A to the Handwerksordnung, a zulassungspflichtiges Handwerk under §1 Abs. 2 HwO — so running your own SHK business (or training apprentices) legally requires a Meisterbrief or an accepted equivalent. It is not required to work as an employed Anlagenmechaniker/in.

• Pipework, brazing/welding and hand-tool proficiencyskillRequired

  Core practical skills built during the Ausbildung: cutting, joining and pressure-testing pipe, plus soldering and welding techniques for sanitary, heating and ventilation systems.

• Heat pump and renewable heating system knowledgeskillOptional

  Increasingly expected as German policy pushes new and replacement heating systems toward heat pumps; many Innungen now offer short heat-pump add-on courses on top of the base Ausbildung.

• Practical experience in a HandwerksbetriebexperienceRequired

  The Ausbildung itself supplies the required practical experience inside an SHK trade business, so no prior work history is needed before starting.

A day in the life of a Plumber

An Anlagenmechaniker/in SHK's day typically starts at the Handwerksbetrieb loading the van with materials and tools for the day's jobs, then travelling between residential and commercial sites. Work ranges from installing new bathroom sanitary systems and pipework to servicing boilers, heat pumps and ventilation systems, with emergency call-outs (Notdienst) for burst pipes or heating failures a routine part of the trade, sometimes outside normal hours. Much of the work is physical — cutting and joining pipe, working in confined spaces or roof voids, lifting equipment — alongside close customer contact, since the final Gesellenprüfung itself is built around a real customer job. Hours are typically a standard collectively agreed working week, with generous statutory holiday entitlement (minimum 20 days, commonly more in practice).

Is it worth it to be a Plumber?

Common mistakes to avoid

• Assuming you need a Meisterbrief just to work as a plumber — it is only required to run your own business or independently train apprentices; employed Gesellen/innen need only the Gesellenprüfung.
• Underestimating Gesellenprüfung Teil 1 because it's worth only 30% of the final grade — failing it can still complicate progression, and it covers fundamentals (pipe joints, measurement) that resurface throughout the trade.
• Treating the Ausbildung as purely a stepping stone to office/management work — most day-to-day Anlagenmechaniker/in roles remain physically demanding on-site work throughout a career, not just during training.
• Not budgeting realistically for the Meisterschule if self-employment is the goal — the roughly €6,400–€10,700 course cost and 1,100 study hours are a genuine multi-year commitment on top of the base Ausbildung, even with AFBG funding available.
• Ignoring heat pump and renewable-heating add-on training — German heating-system policy is shifting away from new gas boiler installations, and employers increasingly value this on top of the base qualification.
