06 — Questions
Your questions before we arrive
What people in Watermael-Boitsfort ask before confirming.
How long for a boiler repair in winter?
The time is given on the phone according to the day's round; a home without heating or hot water comes before a planned service. If a part must be ordered, we give the supplier lead time before you confirm, and we get the system running provisionally when it is safe to do so. See the prices →
Is boiler servicing charged at 6 % or 21 % VAT?
At 6 % if the property is a private dwelling over 10 years old and the invoice is in a private individual's name. That applies to servicing, repairs and boiler replacement. A newer home or business premises is at 21 %. The rate and legal wording appear on the invoice. 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 Watermael-Boitsfort: 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 Watermael-Boitsfort, and the invoice separates call-out, labour and parts.

What heating engineer work is done when the radiators stay cold?

Will my boiler be repaired rather than replaced?
