01 · Key points
What matters for this topic
Assess current energy performance
Involve an energy-efficiency expert early
Check funding before work begins
Compare individual measures and a full renovation
Allow for your own contribution and bridging finance
02 · Context
Plan first, commission later
Funding schemes often require an application or confirmation before work begins. Clarify financing and funding before placing binding orders.
03 · Context
Individual measures or an efficiency house
A staged renovation offers flexibility. A comprehensive renovation may achieve a more consistent energy standard but requires more planning and capital. The technical approach determines financing needs.
04 · Context
Funding conditions change
Programmes, budgets and terms may change. The conditions in force on the application date apply. PremiumHYP therefore includes funding only after checking current requirements.
05 · Be prepared
Points you should not underestimate
- Placing orders too early
- Assuming funding is guaranteed
- Forgetting ancillary costs and construction supervision
- Overestimating savings
- A renovation roadmap without a financing check
