Energy performance certificate (CEE) for foreign property owners
The Certificado de Eficiencia Energética (CEE), also called Energy Performance Certificate, is a legal obligation for almost every property sold or rented in Spain. Foreign owners frequently overlook it until the day of sale — at which point a missing CEE can delay signing. This guide explains exactly when you need a CEE, how to obtain one as a non-resident, its cost and validity, the meaning of energy classes A-G, and the sanctions for non-compliance (which can reach €6,000 for the most serious infractions).

What is the CEE and why it exists
The CEE is a document that rates a property's energy efficiency on a scale of A (most efficient) to G (least efficient), based on calculated CO₂ emissions per square metre and primary energy consumption. It is issued by a qualified técnico competente (architect, building engineer, technical engineer) who inspects the property and certifies its performance.
The legal basis is RD 235/2013, which transposes EU Directive 2010/31/EU on the energy performance of buildings. Updated by RD 390/2021 to extend the obligation to rentals over 4 months and incorporate near-zero-energy building standards. Each autonomous region maintains its own registry where certified CEEs are recorded.
The CEE is registered with the regional energy agency (each autonomy has its own — for example, FENERCOM in Madrid, ICAEN in Catalonia, AAE in Andalusia). Only registered CEEs are legally valid. A CEE issued by a técnico but not registered does NOT satisfy the legal obligation.
When the CEE is required
Sale: mandatory for ALL property sales. Must be presented to the buyer before signing the notary deed (escritura). The CEE reference must appear in the deed. Without it, the notary may refuse to sign or sign with a 'salvedad' (formal warning).
Rental over 4 months: required for any rental contract longer than 4 months. The owner must provide the CEE to the tenant at signing. Short stays (under 4 months) and seasonal rentals are exempt.
Real estate listings: the energy class must appear in any commercial listing (idealista, fotocasa, agency websites). Listings without the energy class are sanctionable.
Exemptions: buildings of historic protection, places of worship, agricultural buildings without heating/cooling, isolated buildings under 50 m², industrial buildings with specific exemptions. New construction is automatically required to obtain CEE before completion.
How to get a CEE as a foreign owner
Step 1 — Hire a qualified técnico. The technician must be registered to issue CEEs in the relevant autonomous community. Architects, building engineers (aparejadores) and technical engineers are eligible. Look for one with experience in your region (regional registry requirements differ).
Step 2 — Inspection. The técnico visits the property to measure surfaces, identify materials, document HVAC systems, and assess energy performance.
Step 3 — Calculation. The técnico uses one of the officially recognised programs (such as CE3X or HULC) to model energy performance and produce the rating.
Step 4 — Registration. The técnico submits the CEE to the regional energy agency. Once registered, you receive a certificate with a unique reference number. THIS is the legal document.
Time and cost: there is no official tariff: ask several técnicos for a quote and a delivery date, including registration.
Energy classes A-G and market impact
Class A — best. The thresholds for each class depend on the climate zone. Typically new construction or fully renovated.
Class B — very good. Recent construction with high-efficiency systems.
Class C — good. Often recent buildings with double glazing and efficient HVAC.
Class D-E — average. Common in older second-hand homes.
Class F-G — poor. Often old construction, single glazing, old boilers. A G certificate is valid for only 5 years.
Mortgage rate impactSome Spanish banks offer 'green mortgages' for energy-efficient homes: according to their own websites, Abanca, Unicaja, Banco Mediolanum and Deutsche Bank have one for properties with an A or B energy certificate (Mediolanum: B or better). Check whether it is open to non-residents before counting on it: Unicaja's is for residents in Spain and Deutsche Bank's only for a main home.
Sanctions for non-compliance
The scale: minor infractions €300-€600, serious €601-€1,000, very serious €1,001-€6,000. Falsifying the information in a certificate is among the very serious ones.
What gets fined: selling or renting without a registered CEE, not giving it to the buyer or tenant, and advertising a property without its energy class. The regional rules decide how each breach is classified.
Practical enforcement: sanctions are imposed by each region's competent body, which also runs the register of certificates.
