You are applying for a certificate of competence in the Brussels-Capital Region.

To obtain a certificate of competence, you must meet the following terms and conditions:

1. You have taken the course at a recognised training centre in the Brussels-Capital Region.
2. You pass an exam recognised by the Brussels-Capital Region and submit your application for a certificate to RESCert no later than 12 months after the date of the exam. You do not need to provide proof that you have passed the exam; each examination centre regularly sends RESCert a list of students who have passed.
   • Note: before taking the ‘Solar thermal installations for combined systems’ exam, you must first pass the exam on ‘Solar thermal installations for domestic hot water’.
3. You must demonstrate that you have at least one month of relevant professional experience in the technology concerned. If you cannot directly demonstrate that you have practical experience with the technology, you can also demonstrate that you have experience in related activities, this is recorded by technology:
   • For photovoltaic installations: experience in electrotechnical work or in covering and sealing activities.
   • For solar thermal installations – domestic hot water: experience in installation work relating to central heating, air conditioning, gas and plumbing, or roofing.
   • For solar thermal installations for combined systems (domestic hot water and heating): experience in installation work in central heating, air conditioning, gas and plumbing.
   • For biomass boilers: experience in installation work in central heating, air conditioning, gas and plumbing.
   • For biomass stoves: experience in installation work in central heating, air conditioning, gas and plumbing.
   • For heat pumps: experience in electric or installation work in central heating, air conditioning, gas and plumbing, or as refrigeration installer.
   • For superficial geothermal installations: experience as a driller or geologist.

You can demonstrate your experience in the following ways:

• Reference to one of these activities on the BCE, and has been there for more than one month by the time you submit the application. It does not have to be referenced exclusively under the heading ‘professional competence’. This may therefore include a reference also to one of the above activities under ‘VAT activities’ or ‘ONSS activities’, for example.
• Proof of one month’s practical experience issued by a third party, for example a signed declaration from an employer, or from a third party for whom work was done as a subcontractor, etc.
• Another official document proving that the applicant has effectively carried out one of the activities listed in Article 3 for at least one month.
• Proof of membership of a social insurance scheme for self-employed workers and proof that you have installed at least two systems, either in one of the eligible sectors or two systems using the relevant technology (including addresses, photographs, invoices and a declaration of honour).

In order to prove one month of practical experience, experience in the technology of the certificate or related activities (as described in point 3) is taken into account. The following tasks count as practical experience:

• Placing installations
• Regulating / commissioning of installations
• Repair of installations
• Carrying out maintenance of installations
• Project manager / site manager / site foreman / monitoring of installation work in the relevant field

The following tasks do not count as practical experience:

• Tasks relating to preparatory works
• Administrative tasks (e.g. purchasing or sales)
• Drafting of offers
