Spain has implemented several financial incentives to encourage residential energy-efficiency upgrades through 2026. These measures include direct subsidies funded largely by Next Generation EU resources, which can cover up to 40% of renovation costs for eligible works such as thermal insulation improvements and the installation of heat pumps or biomass boilers.

In addition to direct grants, the government provides tax deductions for energy-saving renovations. These deductions range from 20% to 60% depending on the reduction in energy demand or the improvement in the building's energy rating. Starting in 2026, tax benefits will no longer apply to the installation or replacement of equipment that utilizes fossil fuels.
