In Brussels, heating a home represents the largest item on the energy bill. Choosing a heating professional is not just about finding someone to install or repair a boiler: Brussels regulations impose strict periodic checks, and the ban on new gas and oil boilers in new buildings since January 2025 redefines the skills expected of a heating technician.
PEB Regulation in Brussels: What Your Heating Technician Must Master
The regulatory framework for heating in Brussels has tightened in recent years. The order from the Government of the Brussels-Capital Region regarding the inspection and maintenance of heating systems (coordinated on June 6, 2024) sets precise inspection frequencies: every two years for gas boilers, and annually for those using oil or solid fuels.
These inspections must be carried out by a certified PEB boiler technician. The certificate issued after each intervention must be kept for five years. A heating technician who does not mention these obligations during an initial contact, or who does not hold this certification, raises a reliability issue.
Before entrusting your installation to a professional, as detailed in Facefull News’ advice, checking the PEB certification is an effective and rarely bypassed selection filter.
Gas Boiler, Heat Pump: Technical Skills to Verify
Since January 1, 2025, new natural gas and oil boilers are banned in new buildings in Brussels. For projects with permits issued after this date, the professional must be able to offer solutions based on renewable energies, particularly the heat pump.
This transition profoundly changes the profile of a competent heating technician. Installing an air-water or geothermal heat pump requires knowledge in thermal sizing, electrical connections, and managing the supply temperature, which are quite different from those required for a conventional condensing boiler.
Two Distinct Profiles in the Brussels Market
The first profile is the traditional heating technician, trained in the maintenance and installation of gas or oil boilers. They remain necessary for the existing stock, which still represents the majority of Brussels homes.
The second profile combines these skills with specific training in renewable energy systems. For a major renovation or new construction, a technician trained in heat pumps is now necessary.
Asking the question directly (“Do you install heat pumps? How long have you been doing this?”) allows for a quick filtering of profiles suitable for your project.
PEB Certification and Cerga Certification: Concrete Guarantees in Brussels
Beyond PEB certification, Cerga certification serves as a reliable benchmark for natural gas installations. It certifies that the installer complies with current safety standards and has been evaluated by an independent body.
Confusing PEB certification with Cerga certification is common. The former pertains to maintenance and periodic inspection. The latter validates competence for the installation of new gas equipment. A serious professional may hold both, but each covers a different scope.
- PEB certification is mandatory for any technician performing periodic boiler inspections in Brussels. Without this document, the certificate issued has no regulatory value.
- Cerga certification guarantees the compliance of the gas installation with Belgian standards. It protects the owner in case of damage related to the installation.
- For heat pumps, no equivalent unique certification currently exists in Belgium, but manufacturers often require specific training to maintain the manufacturer’s warranty.
Comparing Heating Quotes: The Key Factors That Make a Difference
Requesting multiple quotes is a common reflex. The difficulty lies in reading these quotes, as two offers at the same price may cover very different services.
A detailed quote should separately mention the cost of materials (boiler, heat pump, radiators, thermostatic valves), labor, travel expenses, and any additional work (adaptation of the flue, electrical compliance).
Items Often Missing from Incomplete Quotes
- The hydraulic and electrical connections, which can represent a significant portion of the total budget for a heat pump.
- The commissioning and initial adjustment, sometimes charged extra even though they condition the system’s performance.
- The cost of the PEB certificate after installation, which some technicians include and others do not.
- The labor warranty, distinct from the manufacturer’s warranty on the equipment. Its duration varies from one professional to another.
A quote that generalizes everything into a single line (“boiler installation: X euros”) does not allow for comparison. Asking for details item by item remains the most reliable way to assess the transparency of the professional.
Boiler Maintenance in Brussels: Frequency and Penalties
Regular maintenance is not optional in Brussels. PEB regulations impose it, and penalties for non-compliance can reach administrative fines. The technician you choose for the installation should also be able to ensure this maintenance over time.
An annual maintenance contract simplifies regulatory follow-up and prevents forgetfulness. It also guarantees priority intervention in case of breakdown during winter, a period when waiting times can significantly increase.
Checking that the professional offers this type of contract, and that they specify the included services (burner cleaning, combustion analysis, replacement of wear parts), provides a clear indication of their seriousness and long-term vision of the client relationship.
The Brussels heating market is evolving rapidly, driven by increasingly precise regulatory constraints and the rise of heat pumps. Choosing a professional capable of navigating between maintaining the existing stock and installing renewable systems, while respecting PEB obligations, remains the most determining selection criterion.
