Hello everyone! Since I’m planning to rent out my property, I had to get the famous Energy Performance Certificate. I’d always heard real estate agents and lawyers talk about it, but I’d never seen one and thought it was something complicated. I just got it last week and found out it’s just one piece of paper, but it’s packed with information. Thinking that other friends on the forum might be curious or find it useful later, especially since the [Energy Certificate] is often discussed, I took a picture to share with you all.

So this is the energy certificate I received. The design might vary slightly between different autonomous communities, but the core information is the same. The most eye-catching part is the colorful rating scale, which looks like the energy efficiency label on a refrigerator. It ranges from A to G, with A being the most energy-efficient and G being the least. My property is quite old, so getting an E was expected, haha. This rating directly determines the energy consumption level you must display in property listings, making it a very important reference for potential tenants and buyers.
How to Understand This Report?
Don’t let its single-page format fool you; the information on a Spanish energy certificate is crucial. I’ll break it down for you, focusing on these key areas:
1. Basic Property Information
This section clearly states the property’s address, cadastral reference number (referencia catastral), and year of construction. The first thing you should do upon receiving it is to verify that this information is correct, especially the cadastral number, as it’s the unique ID for the property and must be accurate.
2. Energy Consumption and Emissions Ratings
This is the core section. It provides two letter grades:
- Consumo de energía: Annual energy consumption per unit of area. This corresponds to the left color bar in the image above and determines how much electricity/gas your property consumes.
- Emisiones de dióxido de carbono: Annual carbon dioxide emissions per unit of area. This is the right color bar and represents the property’s environmental footprint.
People are usually more concerned with the first rating, energy consumption, as it is directly linked to your utility bills. A better rating (closer to A) means the property has better insulation, stays warmer in the winter and cooler in the summer, and results in lower monthly expenses.
The table below helps to visualize what the different ratings generally mean:
| Rating | Property Condition Description |
| A, B | Very efficient. Typically new constructions or properties that have undergone high-standard energy-saving renovations. |
| C, D | Quite efficient. Complies with more recent building standards, offering good living comfort. |
| E | Average. This is a common rating for most older buildings in Spain. |
| F, G | High consumption. Poor insulation, leading to higher utility bills. These are typically older properties in need of renovation. |
The report also includes a list of recommendations on how to improve the property’s energy rating, such as installing double-glazed windows, adding exterior wall insulation, or upgrading to a more energy-efficient water heater. Although these improvements are not mandatory, they are worth considering if you plan to live in the property long-term to save money and increase comfort. In short, this certificate is now a legal requirement for selling or renting a property, is valid for 10 years, and it’s best to be familiar with it!
