Home Energy Certificate
Need an energy certificate for selling, renting or simply understanding how efficient your home is? We can help you understand the process, what affects your rating and what to do next.
What is a Home Energy Certificate?
A Home Energy Certificate shows the energy performance of a property and assigns it a rating from A to G. A is the most efficient and G is the least efficient.
The rating reflects the home’s estimated energy consumption and associated CO2 emissions under standard conditions of use.
Why you should get an energy certificate
Required for many sales and rentals
In Spain, an energy certificate is generally required when selling a property or renting it to a new tenant.
Useful for marketing
The energy rating must be included in property advertising for sale or rent, helping buyers and tenants compare homes more easily.
Highlights improvement opportunities
The certificate can include recommendations to improve efficiency, reduce energy waste and potentially lower running costs.
How the energy rating is calculated
The official rating is not a simple online guess. It must be calculated by a qualified technician using recognised procedures and then registered with the relevant authority.
The calculation considers the building envelope and the technical systems used to condition the home.
- Insulation levels in walls, roofs and floors
- Window type, glazing and solar exposure
- Heating and cooling systems
- Hot water production systems
- Ventilation and, where relevant, lighting
- Use of renewable energy such as solar systems
Simple way to think about it
A home with better insulation, efficient windows, modern climate systems and renewable energy usually needs less energy to stay comfortable. That tends to improve the rating.
A poorly insulated property with older systems usually consumes more energy and may receive a lower rating.
When a Home Energy Certificate is usually needed
- When selling an existing property
- When renting to a new tenant
- For new construction and certain major reforms or extensions
- For some public or larger-use buildings under the applicable rules
Validity
In general, the certificate is valid for up to 10 years. If the property has a G rating, the maximum validity is 5 years.
If the property is improved, it may be worth updating the certificate earlier to reflect the new performance.
Typical certification process
Property review
A technician gathers information about the property, dimensions, envelope and systems.
Technical assessment
The home is assessed using the recognised certification method.
Certificate issued
The certificate and energy label are produced, including the property rating.
Registration
The certificate is registered with the competent regional authority so it can be used correctly for sale or rental purposes.
