02 — Scope
What we do at your place
One technician comes to Haacht, one itemised invoice.
Heating engineer duties in Haacht, covering 56.6 km2 for 15661 inhabitants in 2025 within the arrondissement administratif de Louvain, involve conventional gas boiler service with certificate included and condensing gas boiler service. Homeowners book oil boiler service with nozzle and sweep included, circulation pump replacement, or bleeding and balancing the radiator circuit. Callers should describe symptoms such as thermocouple or sensor replacement needs.
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. Connection to the existing circuit 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 — Method
Four steps, no surprises
The price is fixed on the phone before the technician sets off for Haacht. After that it does not change without your consent.

You call
Boiler type, brand if you know it, symptom or error code. We state the service or diagnosis fee before leaving.
Fee stated by phone2
Diagnosis and pricing
The engineer identifies the cause, shows it to you and states the repair amount, part included. Without your agreement he opens nothing further.
Agreement before any part3
Repair or service
Work carried out, combustion analysis, safety and pressure checks. The system is restarted in front of you.
Verified restart4
Certificate and invoice
Service certificate handed over on site, invoice with travel, labour and parts itemised, VAT at 6 % or 21 % shown.
Documents handed over on site04 — Questions
Your questions before we arrive
What people in Haacht 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 →
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 Haacht: 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 Haacht, and the invoice separates call-out, labour and parts. Request a quote →
