Thermal insulation
Energy-efficient renovations of old buildings are subsidized
The subsidies amount to CHF 2,000 to CHF 200,000 and are calculated depending on the individual components and their surface area. The amount of the expected subsidies can be estimated using the table below. Subsidies are only paid once for each category of measure.
Only buildings (areas of permanently heated rooms) with a building permit issued before March 30, 1993 are eligible for subsidies.
Funding application / certificate of completion
The funding application and the power of attorney must always be submitted in full and in paper form, including all enclosures. Submissions by e-mail are not sufficient. Applications will only be processed once the application documents have been received in full.

The new subsidy rates for thermal insulation measures apply to applications from 24.09.2024
If you have not yet started the work, you can have any approval you have received declared invalid and submit a funding application under the new conditions from 24.09.2024.
To do this, please send us an e-mail to info.energie@llv.li (from 24.09.2024 at the earliest), stating your name, address and the reference number of the funding commitment, confirming that
- the existing assurance is declared invalid,
- the measure has not yet been started and
- the measure is to be subsidized in accordance with the new subsidy conditions.
After a brief review, you will receive a new confirmation of funding from the Energy Agency with the new funding amount. Once you have received the new subsidy confirmation, you can start building the thermal insulation measures.
Minimum subsidy amount The subsidy measure must be extensive enough to reach the subsidy amount of CHF 2,000.
Extensions and conversions/changes of use In the case of conversions, only existing areas that are being renovated to make them more energy-efficient are eligible. In accordance with Art. 4 Para. 2a EEG, measures are not subsidized if they are mandatory due to other legal regulations. This applies to the construction of new areas (e.g. extensions or roof extensions) and changes of use from previously unheated rooms to newly heated rooms (e.g. attic or shed to new residential use).
Year of construction Only buildings with a building permit prior to March 30, 1993 are eligible.
Subsidies are only paid once for each measure; a new subsidy for the same measure is only possible after 20 years. The old grant date is relevant for the assessment of any funding after 20 years.
Forfeiture of entitlement Entitlement to the payment of subsidies lapses if the measures are started before a legally binding guarantee of subsidies has been issued.
Project author The subsidies will only be paid if expert planning and implementation of the measures is guaranteed.
Time limit Pursuant to Art. 25 of the EEG, the guarantee of funding is limited in time. The measure must be started within one year of the decision to grant subsidies and completed within two years.
Mandatory other regulations The measure is not subsidized if it is mandatory due to other legal regulations in accordance with Art. 4. para. 2a) EEG (e.g. development plan, air conditioning, swimming pool heating, conversion, etc.).
