04 — Questions
Your questions before we arrive
What people in Nivelles 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 →
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 Nivelles: 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 Nivelles, and the invoice separates call-out, labour and parts. Request a quote →
Do you really cover Nivelles (1400)?
Yes. Nivelles is in our area, Walloon Brabant included. The nearest municipality we also cover is Ittre, 7.4 km away. The slot is confirmed by phone before the technician leaves. See the prices →
Does a heating engineer visit Nivelles and where is the company based?
FUSE SERVICES covers Nivelles around the clock, operating 22.3 km from our office in Drogenbos. Call 02 886 10 49 at any hour for assistance, as our heating engineer team covers the entire municipality throughout the year. Request a quote →
Which neighbouring covered municipalities can be attended alongside Nivelles?
Nearby covered municipalities include Ittre at 7.4 km, Genappe at 8.8 km, Braine-l'Alleud at 9.9 km, and Braine-le-Château at 10.4 km. All 27 municipalities in the Walloon Brabant zone receive complete coverage under the same continuous service. See the prices →
Will a technician repair my boiler rather than replace it?
Our heating engineers do not propose a boiler replacement when a priced repair will do. Interventions focus on repairing components such as thermocouple or sensor replacement, expansion vessel replacement, or boiler heat exchanger replacement. Request a quote →
What is included in a boiler service and what paperwork is handed over?
A conventional gas boiler service includes an official certificate handed over upon completion. For oil systems, the intervention includes both nozzle replacement and flue sweeping, with no service ever invoiced without a certificate handed over. See the prices →
Are the sub-localities of Nivelles also covered by the heating engineer?
Heating engineer call-outs cover all sub-localities of the municipality, including Baulers, Bornival, and Monstreux. Residents across every part of postcode 1400 can access assistance 24 hours a day, 7 days a week, public holidays included. Request a quote →

Agreement before any part3
Repair or service
Work carried out, combustion analysis, safety and pressure checks. The system is restarted in front of you.

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 Nivelles, one itemised invoice.
Across an area of 60.6 km2 with 28521 inhabitants, heating engineer interventions in Nivelles frequently involve condensing gas boiler service or an oil boiler service with nozzle and sweep included. Technicians also undertake fault diagnosis with call-out and one hour of labour, circulation pump replacement, or bleeding and balancing the radiator circuit. When phoning, residents should describe the symptoms and boiler model, as the labour charge is stated on the call before work begins.
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

- 02No part ordered without its price being stated.
- 03No service invoiced without a certificate handed over.
