04 — Questions
Your questions before we arrive
What people in Ottignies-Louvain-la-Neuve ask before confirming.
Can the service fee quoted go up on site?
Not for the service itself: the fee depends on the boiler type you gave and includes cleaning, checks, combustion analysis and certificate. Only a flue sweep or a worn part found on site is added, and only after the engineer has shown and priced it to you. See the prices →
What guarantee covers a replaced part?
New parts are covered by the two-year legal conformity guarantee under Belgian law, plus the manufacturer's warranty where it is longer. The labour guarantee is written on the invoice. An identical fault on the same part within that period is redone without a diagnosis fee. Request a quote →
Breakdown tonight: emergency or appointment tomorrow?
A smell of gas is an emergency for Sibelga or 112, not for a heating engineer. For a boiler that has stopped without danger, next-day working-hours appointment costs the normal fee; an evening or weekend visit carries the surcharge stated on the phone. We give you both options and the price of each. See the prices →
Conventional gas boiler service (certificate included) in Ottignies-Louvain-la-Neuve: how much does it cost?
The Belgian market in 2026 sits between €100 and €135 excluding VAT for conventional gas boiler service (certificate included), night and weekend surcharges excluded. This is not our own rate card: your exact amount is announced on the phone before the technician leaves for Ottignies-Louvain-la-Neuve, and the invoice separates call-out, labour and parts. Request a quote →

Will the price of a boiler replacement part be stated before it is ordered?
Yes, no part is ordered without its price being stated beforehand. You learn the exact cost of components such as a circulation pump or thermocouple on the phone or during diagnosis before any order proceeds. See the prices →
Which neighbouring covered municipalities can be attended in the same area?

Are the sub-localities Céroux-Mousty and Limelette included in the service?
Yes, both Céroux-Mousty and Limelette are fully covered as sub-localities of the municipality. Heating engineer call-outs attend addresses in Céroux-Mousty and Limelette 24 hours a day, 7 days a week, public holidays included. Request a quote →
