4. Perform the technical safety review
During the inspection, the authorized installer will conduct a thorough review of all connections, pipes, valves, and safety systems in your gas installation. They'll verify there are no leaks, pressure is correct, and all components function properly according to regulations. This process is mandatory to obtain a valid certificate.
What can change your final price
Even similar projects can end with different budgets. These are the factors that most often push costs up or down.
Type of installation
Residential installations (single-family homes or apartments) have lower costs, while commercial, industrial facilities, or large buildings can exceed 200-300 €. The complexity of the installation directly influences the price of the inspection certificate.
Age and condition of the installation
New installations require less inspection time than older or deficient ones. If irregularities or adaptation work are detected, the technician may charge a supplement for extended inspection.
Distance and travel
Travel costs vary depending on the geographic area and distance from the installer's office. Some professionals charge a fixed rate in urban areas and add travel expenses in rural or remote areas.
Additional certifications required
If additional inspections, pressure tightness tests, pressure measurements, or special certificates are required, these complementary services significantly increase the final budget.
What is a gas installation certificate and how much does it cost?
The average price of gas installation certificates for residential installations ranges between 80 € - 120 €. For commercial premises, it can exceed 200 €.
A gas installation certificate is an essential document to be able to enjoy the supply. It is because it verifies to the gas company that the installation complies with all regulations and is safe. For this reason, it is only valid if issued by an authorized installer.
Regulations on gas installation certificates
The average price of gas installation certificates for residential installations ranges between 80 € - 120 €. For commercial premises, it can exceed 200 €.
The certificate details the main characteristics of the installation and each of its components, which must be reflected in a detailed sketch. Along with this, it must include the types of equipment that will be connected to the gas installation, such as the boiler or even the meter. Other essential data include a statement confirming that the installation meets ideal conditions and the details of the technician who performed the inspection and gave approval.
To start up a gas installation, a series of procedures must be completed and certain certificates obtained:
- Gas installation certificate or bulletin: certifies that the gas installation is valid and complies with regulations. This gas installation certificate is required by the distribution company. It is needed to activate gas in a new building or home, but also when it is a second residence and the gas supply has been disconnected for a long time or in case of changes to the installations. It is also useful to know how much it costs to activate gas.
- Gas boiler installation certificate or bulletin: in case you have one prior to the current one and after changing the boiler, a modification will be validated by issuing a new certificate in accordance with the new boiler that has been installed. This procedure must always be carried out by an authorized technician and will be required by the supply company when conducting the mandatory periodic inspection.
- Individual gas certificate to activate an installation that has been shut down for 2 years: 50 €.
- Issuing natural gas certificate for boiler relocation: 80 €.
Regulations are very strict regarding all aspects of gas installations, as safety is a fundamental concern, and they affect both installations that operate with piped gas and those that use gas stored in tanks, such as butane or propane.
Both the Regulation on Thermal Installations in Buildings (RITE) and the Technical Building Code (CTE) regulate this type of installation. The former establishes that for a gas certificate to be valid, it must include, at minimum, the technical characteristics of the installation, the identification of the installing company and technician, results of commissioning tests, and a responsible declaration that the installation complies with regulations.
The RITE also requires that the inspector must verify that materials and equipment are approved and perform a check on the execution of the installation and on it being ready for use.
- Interior gas connection: the part of the installation between the connection and the building's shutoff valve.
- Common gas installation: from the building's shutoff valve to the users' valves.
- Individual gas installation: from the user's valve to the equipment connection valves.
