How much does an energy reform cost in Spain?

An efficient home contributes to the environment and saves more than 300 euros a year on electricity bills, according to data from Idealista.

Carrying out an energy reform is the right way to improve the energy efficiency of your home . In the following lines you will understand why, how much this change can cost and how long it will take to recover the investment.

What is energy reform and why is it important?

Energy renovation of a home consists of a series of improvements aimed at optimizing energy consumption and increasing the efficiency of the property . This can include everything from installing double-glazed windows to incorporating solar panels or more efficient heating systems.

Why is this important? You probably already have the answer in mind, but here are the three key elements:

• Economic savings : an efficient home consumes less energy, which translates into lower electricity and gas bills.
• Sustainability : Reducing energy consumption also helps reduce CO₂ emissions, contributing to the fight against climate change.
• Property revaluation : energy reforms increase the value of the property, which can be key if you decide to sell it in the future.

In addition, living in an efficient home improves thermal and acoustic comfort , creating more pleasant and healthier spaces for you and your family.

How much can you save with an energy reform?

The average annual savings can exceed 300 euros, according to the initial energy certification data of the home. In cities such as Guadalajara, Cuenca or Toledo, this saving can reach up to 372 euros per year.

Improving energy efficiency not only reduces costs in the short term, but also protects homeowners against future increases in energy prices . In addition, these savings can be even greater if several improvement measures are combined, such as thermal insulation and the installation of renewable energy.

In addition, by improving your energy certification by two levels, you will also be complying with future regulations that will require minimum E ratings from 2030 , ensuring that your home is prepared for the future.

Factors influencing the cost of energy reform

The price of an energy reform can vary depending on different aspects:

• Size of the home : The larger the surface area, the more material and work will be required.
• Initial condition : if the property has serious insulation problems or very old systems, the investment will be higher.
• Type of reform : changing windows is not the same as installing solar panels or renewing heating systems.
• Location : Costs vary between cities. For example, in Palma de Mallorca the average price is 11,479 euros, while in Madrid it is around 7,224 euros.

In addition to these factors, there are other factors such as the quality of the materials used and the fees of the professionals hired, which also significantly influence the total cost.

Approximate cost of an energy reform in Spain

The average cost of an energy reform ranges between 7,000 and 11,000 euros , depending on the factors mentioned and according to data from the Idealista portal.
However, for more ambitious projects, such as installing comprehensive solar or geothermal energy systems, the cost can exceed 20,000 euros. The amount can be even higher if you embark on building a passive house.
It is important to keep in mind that investing in energy efficiency does not only represent an initial expense, but a long-term commitment to savings and sustainability.

How long will it take to recover the investment?

With an average saving of 300 to 370 euros per year, it can take between 15 and 20 years to recover the investment . However, factors such as subsidies, energy prices and the possibility of increasing savings can speed up this period.

For example, if you choose to install solar panels with batteries, you can reduce your dependence on the electricity grid, which significantly increases savings. In addition, the durability of these systems, which usually exceeds 25 years, guarantees long-term economic benefits.

Grants and aids

There are different grant programs that can help you reduce costs:

• PRTR Residential Rehabilitation Plan : financed with Next Generation funds, it offers aid of between 6,300 and 18,800 euros per home, depending on the energy savings achieved.
  
• Tax deductions : you can obtain deductions of up to 60% in personal income tax if you reduce consumption by 30% or improve energy efficiency to levels A or B.
  
• Local bonuses : some local councils offer reductions in IBI as an additional incentive.

In addition to these grants, some autonomous communities have specific programmes that promote energy rehabilitation, such as low-interest loans or additional incentives for homes in rural areas.

How to finance an energy reform

If you are thinking of renovating your home to make it more efficient, it is important to have financing options that suit your needs . After all, we are talking about considerable amounts, so it is advisable to see the best way to deal with this outlay.

For example, there are solutions that allow you to finance both the purchase and renovation of a home in the same package.

You can also explore green credit lines designed specifically to finance sustainability projects, with favorable conditions such as low interest rates and flexible repayment terms.
