The Problem

Most Certificates Are Just Paperwork

In Spain, energy efficiency certification is legally required to sell or rent any property. Most owners treat it as a last-minute formality, paying for a document they never read or understand. The certificate arrives, shows a letter and number, and goes straight into a drawer.

Last-Minute Rush

Property owners typically order their certificate the day before listing their property, treating it as an administrative burden rather than valuable information about their asset.

Meaningless Document

The standard certificate shows a rating from A to G, but offers no context about what that rating means for operating costs, market value, or improvement potential.

Missed Opportunity

Without understanding what drives their rating, owners miss opportunities to make cost-effective improvements that could increase property value and reduce ongoing expenses.

Our Solution

Certification Plus Understanding

We provide the legally required energy efficiency certificate along with a comprehensive supplementary report that explains what your rating actually means. You receive specific improvement recommendations with estimated costs and projected savings.

Our reports identify which upgrades would meaningfully improve your rating, what those improvements typically cost in the Madrid market, and how they affect both energy consumption and property value perception.
