Grants and subsidies for retrofits in the Canary Islands (2026)

Energy retrofits still have public support in 2026, much of it linked to European Next Generation funds and Canary Islands regional programmes. These grants can cover a meaningful share of the investment - typically a percentage of the eligible cost, tied to the energy improvement achieved - which changes the maths on works such as insulation, efficient windows and aerothermal systems.

Eligible works

• Insulation for facades, roofs and floors, including external systems.
• High-efficiency windows and glazing.
• Aerothermal systems and efficient climate systems.
• Ventilation and envelope improvements.
• Solar shading and cool roofing, which matter in the island climate for keeping homes comfortable without heavy air conditioning.

Common requirements

Programmes usually require a demonstrable improvement in the energy rating, with certificates before and after the work, and compliance with the application deadlines. The amount depends on the savings achieved and the type of work. In practice the paperwork matters as much as the building work: the energy certificate, the technical project and the invoices all have to line up for the grant to be paid.

How the application works, step by step

• 1. Energy certificate (before): an assessor records the home's current rating as the baseline.
• 2. Project and quote: we define the works and the expected improvement so the application can be sized correctly.
• 3. Application within the deadline: many programmes work on a first-come, first-served basis until the budget is exhausted, so reserving your place early matters.
• 4. Carry out the works: with invoices and documentation kept in order throughout.
• 5. Energy certificate (after) and justification: the improved rating is certified and the file is submitted for payment.

Worked example

Take a southern home that is hot in summer and leaks conditioned air: replacing single glazing with high-efficiency windows, adding roof and facade insulation and fitting an aerothermal system can lift the energy rating by one or more letters. Where a programme reimburses a share of the eligible cost against that improvement, the effective outlay for the owner falls - and the home is cheaper to run afterwards. The exact percentage depends on the programme open at the time and the rating jump achieved, which is why we confirm the current terms before you commit.

Grants and IGIC together

Grants and the reduced IGIC rate are separate mechanisms and can often apply to the same primary-residence project, compounding the saving. Many of these works in the Canary Islands may benefit from a reduced IGIC rate on top of any grant.

How we help

At Ecoinnova we explain the grants that are current when you apply and manage the application together with your energy retrofit, handling the before-and-after certificates and the justification file. Because programmes and deadlines change through the year, the right first step is a visit and a fixed quote so we can match the works to whatever support is open.
