We work in Liège with a team of technicians who understand heating in the Meuse building stock — from the high-ceilinged master houses of Outremeuse and Le Laveu to the villas on the hillsides of Cointe and Sainte-Walburge, where replacing an old oil boiler with a heat pump changes everything on the bill.

Liège falls under the grants of Wallonia. Here are the levers we set up and deduct directly from your bill, with nothing for you to pay up front.
Wallonia supports installing a heat pump through the Habitation grant, scaled according to the household income brackets. A home audit may be required depending on your application ; we check your eligibility and prepare everything.
For a home more than 10 years old, VAT drops from 21 % to 6 % on the supply and installation of your heat pump. Applied directly on your quote.
We prepare the entire Habitation grant application and coordinate any audit ; the grant is deducted from your bill, with nothing to pay up front and no form to fill in.
The full details of amounts, conditions and income brackets are on our heat pump prices & grants page. We prepare the entire application : you pay nothing up front and fill in no forms.

For an existing Liège home, an air-to-water heat pump works very well with low-temperature radiators or underfloor heating; for an apartment, an air-to-air heat pump with discreet units is often the best option.

As Liège falls under Wallonia, you can benefit from the Walloon Habitation grant for installing a heat pump (scaled according to income brackets, with a possible home audit) and from 6 % VAT if your home is more than ten years old. We set up and deduct this support; all the amounts are detailed on our prices & grants page.
