03 — Questions
Your questions before we arrive
What people in Lennik 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 Lennik: 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 Lennik, and the invoice separates call-out, labour and parts. Request a quote →

Yes. Lennik is in our area, Flemish Brabant included. The nearest municipality we also cover is Pepingen, 4.5 km away. The slot is confirmed by phone before the technician leaves. See the prices →

How do I reach the company and what should I say on the phone?

05 — Method
Four steps, no surprises
The price is fixed on the phone before the technician sets off for Lennik. 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 site06 — Scope
What we do at your place
One technician comes to Lennik, one itemised invoice.
Heating engineer call-outs in the municipality of Lennik, which covers an area of 30.8 km2 for a population of 9024 inhabitants, address a variety of central heating faults. Residents book bleeding and balancing the radiator circuit, fault diagnosis with call-out plus 1 h, or circulation pump replacement. When telephoning, having your boiler type noted helps establish whether you require an oil boiler service or a condensing gas boiler service. The labour 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.
07 — Commitment
What will never appear on your invoice
The number one complaint about repair firms is the line nobody saw coming. Here are the ones we rule out.
Document · Commitment
- 01No boiler replacement proposed when a priced repair will do.
- 02No part ordered without its price being stated.
- 03No service invoiced without a certificate handed over.
- 04No seasonal surcharge: the October fee is the May fee.
