GEAK Plus
The reference energy audit with a costed advisory report. CHF 500-2,000 flat subsidy. Key leverage to unlock higher subsidies.
Overview
The GEAK Plus (Cantonal Energy Certificate for Buildings Plus) is a detailed analysis of your home's energy performance accompanied by actionable renovation scenarios. It's often required to unlock the highest subsidies.
What's in a GEAK Plus: energy label (A to G), heat loss analysis, costed renovation scenarios, energy savings estimate. Part of the GEAK Plus cost is itself subsidized (CHF 500 to 2,000 depending on the canton).
Why it matters: unlocks higher subsidies (global renovation bonus for a 2-class jump), clarifies priority works, underpins any major renovation. Note: the GEAK Plus flat subsidy is capped until December 31, 2026.

The GEAK Plus is both an energy label for the building (A to G) and an advisory report with costed renovation scenarios. It's often required to unlock the highest subsidies and to trigger global-renovation bonuses (2-class jump).
How much does a GEAK Plus cost?
Full price ranges from CHF 500 to 3,000 depending on building size and complexity. The cantonal flat-rate subsidy (CHF 500-2,000) covers a significant share. This flat subsidy is capped until December 31, 2026 — benefit this year while you can.
