01 — Scope
What we do at your place
One technician comes to Waterloo, one itemised invoice.
A boiler that stops in Waterloo first raises a question of money: repair or replace? An honest heating engineer answers with figures, not with worry. We start with a fixed-fee diagnosis, stated on the phone. It leads to an amount for the repair, part included, or to a replacement quote if repairing no longer makes sense. In Brabant wallon most homes are over 10 years old and 6 % VAT applies to both options. We work on wall-hung and floor-standing gas boilers, condensing or conventional, and on oil installations. Parts fitted are manufacturer references or common compatible items, listed on the invoice. And because the team also covers plumbing and electrics, the connection, bleeding and thermostat are dealt with in the same visit.
Oil boiler service
Nozzle replacement, combustion chamber cleaning, flue sweeping where needed, burner adjustment and flue gas measurement. Mandatory annual certificate.
Boiler repairs
Error code, lockout, no hot water, burner that will not start. Fixed-fee diagnosis, then repair amount stated before any part is ordered.
Pump, vessel, valve
Replacement of the parts behind pressure and circulation faults: pump, expansion vessel, safety valve, automatic air vent. Part reference shown on the invoice.
Radiators and thermostats
Bleeding and balancing the circuit, thermostatic valve replacement, fitting a room or smart thermostat. Wiring by our electrician where needed.
Boiler replacement
When repairing no longer makes sense: written quote for a condensing boiler, removal of the old one, connection, commissioning and first certificate.

03 — Questions
Your questions before we arrive
What people in Waterloo 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 →
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. Request a quote →
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. 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 →
What should I prepare before the heating engineer's visit?
Clear access to the boiler and gas meter, and find the last service certificate and the manual if you have them. A WhatsApp photo of the rating plate and the error code lets us bring the right part and often avoid a second visit. See the prices →
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. Request a quote →
Conventional gas boiler service (certificate included) in Waterloo: 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 Waterloo, and the invoice separates call-out, labour and parts. See the prices →
Do you really cover Waterloo (1410)?
Yes. Waterloo is in our area, Brabant wallon included. The nearest municipality we also cover is Braine-l'Alleud, 4.3 km away. The slot is confirmed by phone before the technician leaves. Request a quote →
