Boiler servicing is compulsory in Belgium and may only be carried out by a technician certified by your region: they sign the certificate you have to keep, and in Brussels they file it with Brussels Environment. A service done by anyone else has no legal value, however well it is done.
We offer it because it falls in the same season as the ventilation service, for the same households, and nobody does both in one visit. We only do it together with the ventilation: that is the air + heating pack, your ventilation service and your boiler service, one trip, one appointment.
The pack price depends on your ventilation, extract-only or heat-recovery, and is the same for a standard or a condensing gas boiler. It is shown before you book.
Legal intervals by region
What this service costs
One price per system, published before you book, with no questionnaire to fill in to get it. Anything out of the ordinary (a lot of valves, an unreachable unit, a system never opened) we tell you before the visit, never on the invoice.
Air + heating pack, extract-only
Your extract-only ventilation service and your gas boiler service, condensing included, in one visit.
€289
Air + heating pack, heat-recovery
Your heat-recovery ventilation service and your gas boiler service, condensing included, in one visit.
€309
Prices exclude VAT. 6 % on servicing in a private home over ten years old, 21 % otherwise.
What the service covers
Heat exchanger and burner cleaning
Dismantling, dust removal, cleaning of exchanger and burner. On a condensing boiler, the trap and condensate drain are cleaned as well.
Safety checks
Gas circuit tightness, safety devices, flue gas evacuation, combustion air supply. This is the part of the service that protects the occupants, not the appliance.
Combustion analysis
CO, CO₂, oxygen and flue gas temperature measured with an analyser. Burner adjusted for correct efficiency. The readings appear on the certificate.
Condensing: trap and condensate
On a condensing boiler, the trap is cleaned and the condensate drain checked, a frequent cause of lockouts.
Official certificate
Handed over at the end of the visit, with the technician's certification number and the readings. In Brussels the data is filed with Brussels Environment.
Advice on settings
Heating curve, setpoint, programming: a few settings that cost nothing and cut consumption.
How the visit works
- 1
Booking
Choose the pack that matches your ventilation, extract-only or heat-recovery, give the boiler type, then a time window. The price shown is what you pay.
- 2
The visit
About an hour, a little longer for a condensing boiler. The boiler is off during cleaning, then restarted and adjusted.
- 3
Readings and certificate
Combustion analysis, adjustment, and certificate handover. Keep it until the next one.
- 4
And the ventilation, the same day
Your ventilation unit is serviced in the same visit, and the filters are replaced if you asked for it.
Frequently asked questions
Can I book the boiler service on its own?
No. We service the boiler together with the ventilation, in a single visit: that is the air + heating pack. If you have no ventilation system to service, a certified heating engineer will serve you better than we can.
Is the certificate included?
Yes, always. It is the whole point of the legal service: without a certificate signed by a certified technician, the service is worth nothing to your insurer, your landlord or the authorities.
Who does the service?
A technician holding the regional certification for gas boilers, valid in Brussels, Wallonia and Flanders. Their certification number appears on the certificate. It is not optional: we do not have a boiler serviced by anyone without it, and that is also why we do not take oil.
Can the boiler and the ventilation be done the same day?
Yes, and it is the only way to have us service your boiler: the air + heating pack. One trip, one appointment. It applies to a gas boiler, standard or condensing.
What if the boiler has broken down?
A service is not a repair. If the appliance has stopped or keeps locking out, describe the problem through the form: we will tell you whether a service is enough or whether you need a heating repair, which we do not do ourselves.
