How Do I Know My Property’s Energy Rating?
You’ll need an Energy Performance Certificate (EPC), also known as a Certificado de Eficiencia Energética (CEE) in Spain. A certified technician will assess your property’s insulation, heating, cooling systems, windows, and overall efficiency. The EPC certificate is valid for 10 years and gives a rating from A (most efficient) to G (least efficient).
NOTE: From 2030 onward, non-compliant properties cannot be legally sold or rented! Attempting to do so may result in administrative fines, legal restrictions, or even the removal of property listings. Additionally, homes that don’t meet these energy standards risk losing value on the market.

What Are the Average Costs to Upgrade An Energy Rating?
Renovation costs depend on your property’s age, size, and condition.
Typical expenses include:
Thermal insulation: €2,000–€8,000
Energy-efficient windows and doors: €3,000–€12,000
Heating and cooling systems: €3,000–€10,000
Solar panel installation: €5,000–€15,000
Government grants and green financing options are available to help reduce the costs.
Are holiday rentals affected?
Yes. These new rules apply to all residential properties, including short-term holiday rentals. In tourist-heavy areas such as coastal towns and major cities, local governments may apply even stricter enforcement.
What Are the Deadlines?
2030: Minimum energy rating of “E” required for all property sales and rentals
2033: Minimum energy rating increases to “D”
What Upgrades Should One Prioritize?
To improve your energy rating and comply with the new law, energy efficiency professionals recommend focusing on:
Wall and roof insulation
Double-glazed windows
High-efficiency heating/cooling systems
LED lighting
Smart thermostats
Solar energy systems
Are Rental Contracts Affected?
Yes. New rental contracts cannot be signed after 2030 unless the property meets the energy requirements. Existing long-term leases may continue, but any renewal or change in tenant will require compliance.
Who Can Issue an EPC in Spain?
Only certified architects, engineers, or qualified energy assessors registered in your Autonomous Community can legally issue an EPC.
What Financial Aid Is Available?
Several government-backed programs are available:
PREE (Programa de Rehabilitación Energética de Edificios): Grants for insulation, HVAC systems, and lighting upgrades can cover up to 35–40% of costs
PRTR (Recovery, Transformation and Resilience Plan): Regional subsidies for broader renovations.
Many regions also offer IBI property tax discounts and IRPF income tax deductions for energy efficiency upgrades. You may also be eligible for a green mortgage or loan extension from your bank to finance improvements.
Will Authorities Enforce These Rules?
Yes. From 2030 onwards, energy compliance will be checked during sale or rental procedures. Authorities may issue fines, block transactions, or remove listings for properties without a valid or compliant EPC.
Now is the time to think about investing in your property’s energy efficiency not only to ensure compliance with the 2030 and 2033 energy regulations in Spain, but also to increase its value, and help lower your running costs.
