Fribourg, Bulle, Villars-sur-Glâne, Marly, Estavayer-le-Lac.
The canton of Fribourg combines a densely populated residential plateau (Fribourg city, Villars-sur-Glâne, Marly) with a pre-Alpine fringe (Gruyère, Veveyse) at higher altitudes. Heating demand is noticeably higher here than on the shores of Lake Geneva, which makes ground-source heat pumps (with geothermal boreholes) particularly competitive over the long term. We deliver around thirty projects a year across this territory.
Service area
Local context
Average altitude of 580-800 m on the plateau, rising to 900 m+ in the Gruyère (Bulle, Charmey). Winters are harsher than by the lake: January averages of -3 to -5°C. Annual sunshine of 1,500-1,650 h, comparable to the Lake Geneva plateau. Solar production is slightly lower, but payback holds up thanks to Fribourg's more generous subsidies.
Many renovated farmhouses and chalets in the Gruyère and Veveyse call for discreet integration (solar tiles or PV slate for listed buildings). On the plateau (Fribourg, Villars-sur-Glâne), standard pitched-roof villas dominate: full-black on-roof mounting is the preferred option.
Grid operator: Groupe E (the entire French-speaking area). An efficient connection service with lead times of 3-5 weeks. Good feed-in capacity across the whole territory.
I.ON advice
Above 600 m altitude (Bulle, Châtel-Saint-Denis, Charmey, Le Mouret), an air-to-water heat pump loses 15-25% of its COP in winter. A ground-source unit with vertical boreholes (80-120 m deep) holds a COP of 4+ all year round. It costs 10-20 kCHF more than air-to-water, but the efficiency preserves the payback.
The Gruyère and Veveyse are full of old farmhouses being renovated. The barn roof often offers 100-200 m² of usable surface — ideal for a 15-30 kWp installation with partial feed-in. Returns are excellent when the main building is owner-occupied.
Heating demand in the Gruyère runs 30-40% higher than on the Riviera. Slightly oversizing the heat pump (10-15%) avoids falling back on electric backup during cold snaps and improves the overall annual COP.
2026 subsidies
Standard federal subsidy of 320-380 CHF/kWp.
Fribourg combines a cantonal PV subsidy with heat pump grants through the Buildings Programme. The canton is one of the most proactive in Western Switzerland: typical amounts of 1,500-3,500 CHF per project, and more for whole-building renovations.
The canton of Fribourg actively encourages the CECB+ energy audit (CECB is the cantonal energy certificate). If the audit leads to a whole-building renovation (insulation + heat pump + PV), a cumulative bonus applies across all the measures.
Exact amounts vary from year to year and depend on the specifics of each project. We always calculate the maximum combination of grants available when preparing your quote.
Frequently asked questions
Yes, but choosing the right type is crucial. At that altitude, a standard air-to-water heat pump loses performance in deep cold (outdoor temperatures below -10°C several days a year). We recommend either a high-performance air-to-water unit (Stiebel Eltron WPL classic) or a ground-source (geothermal) heat pump for more ambitious projects. The annual COP stays above 3.5 in every case.
Yes, both towns are part of our regular service area. Bulle is 70 km from our Rolle headquarters (1h15 by motorway), Estavayer 75 km. For projects in Fribourg, we bring in a local partner team for maintenance call-outs so we can guarantee a response time under 48 hours.
In certain categories (combined heat pump + insulation, CECB+ projects), yes. Fribourg has made the energy transition a strong political priority. The exact amounts change every year — we always calculate the maximum combination of grants available for each project at quote stage.
