02 — Method
Four steps, no surprises
The price is fixed on the phone before the technician sets off for Tremelo. After that it does not change without your consent.
1
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 site03 — Scope
What we do at your place
One technician comes to Tremelo, one itemised invoice.
Serving 14842 inhabitants in Tremelo involves interventions such as conventional gas boiler service with certificate included, flue sweeping, and bleeding and balancing the radiator circuit. Technicians also carry out circulation pump replacement, thermocouple or sensor replacement, or boiler heat exchanger replacement. When calling, describe whether the installation requires an expansion vessel replacement or boiler maintenance, and note that the amount is stated on the phone before the technician leaves.
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.

05 — Questions
Your questions before we arrive
What people in Tremelo 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 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 →
Conventional gas boiler service (certificate included) in Tremelo: 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.
