I’ve been looking at properties recently, both for rent and for sale, and I’ve noticed that all listings have a colorful label with a scale from A to G, often with ‘CEE’ written next to it. After asking an agent, I learned it’s the Energy Performance Certificate, a mandatory document for all properties being rented or sold in Spain.
At first, I thought it was just another piece of red tape. But after digging deeper, I realized it’s actually quite important! It’s like an ‘energy ID’ for the house, showing you how well it performs in terms of insulation, thermal efficiency, and energy consumption. The rating goes from A (most efficient) to G (least efficient). The difference of a single grade can mean a significant change in your monthly electricity and gas bills. Especially when you need heating in the winter and air conditioning in the summer, a G-rated property can feel like a bottomless pit for your money—something you only realize once you’ve moved in and see the bills.

Who Needs to Obtain an Energy Performance Certificate?
Simply put, if you want to put your property up for sale or rent, you must obtain this certificate before advertising it. The energy rating label must be displayed on real estate websites and in window displays. As a tenant or buyer, we have the right to ask the landlord or seller to see the full Spanish energy certificate report. If a landlord signs a contract with you without having this certificate, they are technically in violation and could face fines of up to several thousand euros. While we as tenants may not be directly liable, it does reflect on whether the landlord is compliant and professional, doesn’t it?
How to Read the Certificate’s Rating?
The most intuitive part of the certificate is the colorful A-to-G label. It primarily assesses two indicators: annual CO2 emissions per square meter and annual non-renewable primary energy consumption per square meter. The higher the rating, the better the property’s insulation, window and door sealing, and the efficiency of its air conditioning and hot water systems. The table below gives you a clearer idea of what each rating means:
| Rating | Energy Efficiency | Living Experience | General Description |
| A | Very High | Warm in winter, cool in summer; very low bills | Typically new builds using the best insulation materials and energy-saving equipment |
| B-C | Good | Comfortable living; reasonable energy costs | Most new or well-renovated properties |
| D-E | Average | Standard level; moderate bills | The most common rating in Spain; most older buildings fall into this range |
| F-G | Low | Cold in winter, hot in summer; high energy costs | Old, unrenovated properties with poor sealing on windows and doors |
So, next time you’re house-hunting in Spain, besides checking the price, location, and orientation, don’t forget to take a close look at the rating on the Energy Performance Certificate. If you’re deciding between two similar properties, choosing the one with a higher energy rating certificate will definitely save you money in the long run. Moreover, a landlord who is willing to invest in improving the property’s energy rating is often more reliable in other aspects as well. Hope this little tip helps you out!
