An uninspected heating oil tank represents a major environmental risk and can block a property sale. With Certinergie, bring your installation into compliance quickly and confidently.
The mandatory heating oil tank inspection applies in several key situations. Don’t take risks: a missing inspection can block a transaction or expose you to liability.
Mandatory when selling a property equipped with a heating oil tank, whether above-ground or underground.
Every new tank commissioning requires an initial compliance inspection.
A regular leak test is required depending on the type and age of your installation.
Taking a tank out of service or abandoning it requires a specific inspection and certificate.
If you doubt the tank’s tightness or suspect pollution, an immediate inspection is required.
Certain urban planning or environmental permits require a compliance certificate.
Important : obligations vary between Wallonia and Brussels. Please consult the regional section below to know the rules applicable to your situation.

Everything you need to know before booking your heating oil tank inspection.
How long is a heating oil tank inspection valid?
The validity period varies by region and tank type. Generally, a periodic inspection is required every 3 to 5 years for underground tanks. For a property sale, a recent inspection (usually less than 12 months old) is required.
How long does the on-site inspection take?
A standard heating oil tank inspection takes 30 minutes to 1 hour, depending on accessibility and required tests. For an underground tank with an in-depth leak test, allow 1 hour.
What happens if my tank is not compliant?
In case of non-compliance, our technician provides a detailed report explaining the anomalies found and the corrective actions to be taken. Once the work is completed, a follow-up inspection can be scheduled to validate compliance.
Do I need to empty my tank before the inspection?
No, it is not necessary to empty the tank. Our technicians are equipped to carry out tightness tests with the heating oil present. Just make sure the tank and its access points (dipstick, cap) are accessible.
Is the tank inspection mandatory for a property sale?
Yes, in both Wallonia and Brussels, a recent heating oil tank inspection is required when selling a property equipped with such an installation. The notary may refuse to pass the deed without this certificate. We recommend arranging it as soon as you put the property up for sale.
How do I decommission a tank I no longer use?
An out-of-service tank must be officially decommissioned through a regulatory procedure: emptying, degassing, filling or removal. Certinergie carries out the inspection certifying this decommissioning, an essential document to regularise your situation.
Do you operate throughout Belgium?
Yes, Certinergie operates in Wallonia and Brussels. Our technicians are present in all provinces and municipalities. When placing your order, simply provide the property address and we will offer available slots in your area.
