New call planned

Arrel Energia is currently working on the final justification of applications from previous calls and monitoring the continuation of Programme 4 in Barcelona. A new call is planned to continue supporting lower energy use and improved comfort in homes.

Grants for work inside homes

Programme 4 supports energy improvements within individual homes. Subject to the final rules, measures may include window replacement, insulation and more efficient heating or cooling systems.

Why prepare now

Defining the work and gathering evidence in advance can make the application process more efficient. Collect the property details, a description of the improvements, available quotations and the initial energy certificate if you have one.

What remains to be confirmed

The official resolution has not yet been published. The opening date, budget, deadlines and final conditions still need to be confirmed before commissioning or starting work.
