The propane tank inspection is mandatory before any refill: no supplier (Antargaz, Primagaz, Repsol, TotalEnergies…) will deliver to your tank without a valid certificate from an inspection body. Atlas Contrôle is accredited by BELAC to ISO/IEC 17020 (No. 663-INSP) for this inspection, which it carries out in Wallonia and Flanders.

Because propane is heavier than air, the installation calls for specific technical arrangements: two-stage pressure regulation, low-level ventilation, safety distances, and cathodic protection for buried tanks. Our inspection covers the whole installation, from the tank through to the combustion appliances.

ⓘ Language of the report: the official report is issued in French or Dutch, as Belgian law requires. An English summary is available on request, free of charge.

First commissioning

The first inspection after your installer has finished. It is what allows the very first fill of the tank to go ahead.

Periodic inspection

Five-yearly renewal that keeps your refill authorisation alive. We send the report straight to your propane supplier.

Inspection after modification

Mandatory after the tank is replaced, the connection changed, an appliance added, or any work carried out on the high-pressure side.

Above-ground or buried tank

We inspect both. For buried tanks we additionally verify the cathodic protection and the tightness of the tank.

Safety distances

We check the regulatory distances between the tank and buildings, public roads and openings (windows, air bricks, inspection chambers).

Complete documentation

Detailed report and certificate of conformity, issued within 24-48h and accepted by every Belgian supplier. For a simple residential installation, the inspector also draws up the isometric diagram. For any other installation, your installer must provide it.

Frequently asked questions

My propane supplier refuses to refill — why? ▾

Without a valid certificate from an inspection body, no propane supplier is allowed to fill your tank. The inspection must be less than 5 years old (10 years under some older contracts). Appointment within 24 to 48 h.

How long is the inspection valid? ▾

Normally 5 years for the periodic inspection. Some older installations still run on a 10-year cycle. An inspection after modification is valid for 5 years from the day of the visit.

What is the difference between an above-ground and a buried tank? ▾

Above-ground tanks need greater safety distances from buildings but are simpler to inspect. Buried tanks require cathodic protection against corrosion, which we verify at every visit.

What happens if my tank fails the inspection? ▾

We issue a report listing exactly what has to be corrected. You then have 6 months to carry out the work and book a re-inspection. Refilling stays prohibited in the meantime.

Do you cover the whole of Belgium? ▾

We inspect propane tanks in Wallonia (Walloon Brabant, Liège, Namur, Hainaut, Luxembourg) and in Flanders (Flemish Brabant, Antwerp, Ghent, Limburg). In the Brussels-Capital Region we inspect the indoor propane or butane installation, not the tank. Travel is included in the quoted price.

Do I need to empty the tank first? ▾

No. The inspection is carried out with the tank in service — we use dedicated equipment to test pressure and tightness without emptying anything.
