Recommended Order
Energy Consulting
First analyze the current state. 80% of consulting costs are funded by the government.
Insulation
Insulate first, then heat. Good insulation reduces heating demand and the size of the new heating system.
Windows
Old windows are thermal bridges. Triple glazing saves significant energy.
Heating Replacement
Now install the properly sized heat pump or other renewable heating system.
Apply for funding BEFORE starting!
BEG funding must be applied for before commissioning. Those who commission first and then apply lose their funding entitlement. Processing currently takes 4-8 weeks.
Frequently Asked Questions
Do I have to replace my heating system in 2026?
Not necessarily. The replacement obligation only applies if your gas or oil heating is older than 30 years AND meets certain criteria. New buildings must heat with 65% renewable energy from 2024.
How much funding is available for heat pumps?
BEG funding includes: Base funding 30%, speed bonus 20% (until 2028), income bonus 30% (under 40,000/year). Maximum 70% funding possible, capped at 30,000 funding amount.
What is the Building Energy Act (GEG)?
The GEG regulates energy efficiency requirements for buildings. From 2024: New heating systems must operate with 65% renewable energy. Existing buildings have transition periods.
Which renovations are funded?
Funded: Heating replacement (heat pump, pellets, solar), insulation (roof, facade, basement), window replacement, ventilation systems, and energy consulting.
When do I have to renovate?
Mandatory: Change of ownership (retrofit obligations), heating older than 30 years (replacement obligation). Voluntary but sensible: When you want to reduce energy costs and increase property value.
