The energy certificate has become an essential document for any owner in Rubí who wants to rent, renovate, advertise or legalize a home. Although many see it as a simple procedure, its importance goes much further: it affects the value of the property, energy consumption and attractiveness to future buyers or tenants.
In Havitec We manage this document for dozens of owners every month, and we still detect common doubts:
What is it really for?
How much does it cost to issue it?
Is it always mandatory?
Does it influence the sale or rental price?
This guide is designed to resolve all these questions in a clear and updated way by 2025.
What exactly is the energy certificate?
The energy certificate (or CEE) is an official report that evaluates the energy efficiency of a home. It includes a letter between A and G that indicates its consumption and emissions.
— A: maximum efficiency
— G: very low efficiency
Its objective is to inform the user about the estimated energy consumption and promote more sustainable homes.
The report is issued by a qualified technician and has a 10 year validity.
What is the energy certificate for in a home in Rubí?
Although many owners see it as just another procedure, its functions are key in 2025.
Serves for:
Inform the future buyer or tenant about the home's consumption
Detect energy improvement points
Access certain aid or subsidies
Update the legal documentation of the property
Avoid penalties for not having it when publishing ads
And most importantly: homes with better energy ratings usually have more interest and sometimes they are rented or sold before.
Is the energy certificate mandatory in 2025?
Yes, and more than ever.
The EEC is mandatory in Ruby for:
Publish an ad on real estate portals
Sign a sales contract
Rent a home
Reform certain structural elements
Request energy efficiency aid
Register the certificate of habitability in some cases
If the certificate is not available, the sanctions can range from 300 € y 6.000 €, depending on the case.
In Havitec We help owners process everything necessary to avoid delays or fines.
How much does it cost to issue an energy certificate in Rubí?
The price depends on the size of the home and its location, but in Rubí the usual rates range between:
— 85 € y 150 € for standard floors
— 150 €–250 € for single-family homes
The factors that affect the price are usually:
Surface
Accessibility
Age of the building
Conservation status
Number of plants
At Havitec we work with approved technicians to guarantee speed, accuracy and a fair price without surprises.
How is energy certification carried out?
The technician visits the property and collects key information: thermal envelope, orientation, materials, windows, air conditioning systems, type of lighting and general condition of the building.
The usual process includes:
Data collection and measurements
Review of plans or technical documentation
Analysis of consumption systems
Preparation of the report
Official registration in the Generalitat
Once registered, the owner receives the certificate and energy label.
What can improve your energy letter?
Although the certificate simply evaluates, many owners take the opportunity to improve their home with simple actions that can raise the energy rating and increase the attractiveness of the property.
Most effective improvements in Ruby:
Change windows to double glazing
Install LED lighting
Upgrade the heating system
Improve insulation in key points
Replace inefficient appliances
These improvements also reduce energy bills month after month.
Does the energy certificate influence the price of housing?
In 2025, yes.
Every year the number of buyers who review the energy label and compare options increases.
A letter A, B or C can:
Increase perceived value
Offer more interest in portals
Reduce time on market
Differentiate yourself from close competitors
In Havitec We observe that apartments with good certification have more visits and usually receive faster offers.
Can Havitec manage the energy certificate?
Yeah.
Many owners prefer to delegate it to avoid paperwork and ensure speed.
Havitec manages:
Technician request
Visit coordination
Sending the report
Official registration
Delivery of the energy label
And, if the owner wants, we advise on possible improvements to increase efficiency before selling or renting.
