Energy prices, grant rules, and installation costs change frequently. The figures on this page are planning ranges, not quotes. Always confirm your current tariff, delivered fuel price, installer scope, and eligibility in the named references linked below.

Belgium summary

Gas is widespread in urban areas; oil and other fuels remain in part of older or off-grid stock.

Belgium has regional building and policy differences, with heating choices affected by urban gas access and building age.

Regional incentives and electricity pricing can change the case for heat pumps significantly.

Typical heating context

  • Gas boilers
  • Oil boilers
  • Heat pumps
  • District heating in limited areas

Energy cost assumptions (planning ranges)

  • Electricity: EUR 0.25-0.40 per kWh
  • Gas: EUR 0.09-0.15 per kWh
  • Heating oil: EUR 0.08-0.13 per kWh equivalent

Because Belgian support is regional, this page should be treated as a national planning layer only.

Grant and support schemes

Regional support differs: Flanders, Wallonia, and Brussels each run separate eligibility and payment structures

Support is region-specific. Homeowners should check Flanders, Wallonia, or Brussels rules as applicable.

Heat pump suitability notes

Regional incentive rules should be checked first because support and technical conditions differ by region.

Worked example (illustrative)

At EUR 0.32/kWh electricity and EUR 0.12/kWh gas, SCOP 3.2 implies ~EUR 0.10/kWh delivered heat from a heat pump versus ~EUR 0.13/kWh from a 90% gas boiler.
