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.

Luxembourg summary

Gas and oil still present in legacy stock, with increasing interest in heat pumps and whole-home renovation.

Luxembourg has a temperate climate, but high incomes and property values can make whole-home upgrades more feasible for some households.

Grant rules, installer quotes, and building standards are central to the financial case.

Typical heating context

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

Energy cost assumptions (planning ranges)

  • Electricity: EUR 0.15-0.27 per kWh
  • Gas: EUR 0.07-0.12 per kWh
  • Heating oil: EUR 0.08-0.12 per kWh equivalent

Small-market supplier variation can still be meaningful; verify tariff terms and subsidy cap rules.

Grant and support schemes

Klimabonus / Klima-Agence pathways can support eligible heat pumps and renovation measures

Klima-Agence and government resources provide current subsidy guidance for eligible home energy measures.

Heat pump suitability notes

Pairing heat pump replacement with envelope upgrades often improves both comfort and payback resilience.

Worked example (illustrative)

At EUR 0.20/kWh electricity and EUR 0.09/kWh gas, SCOP 3.2 implies ~EUR 0.06/kWh delivered heat from a heat pump versus ~EUR 0.10/kWh from a 90% gas boiler.
