An 18th-century manor house with exceptional proportions, a penthouse with breathtaking city views, a seaside villa… These exceptional properties boast numerous advantages, but sometimes share an unexpected commonality: a poor Energy Performance Certificate (EPC). In a luxury real estate market where expectations are high and buyers demanding, this result can seem insurmountable. However, it is not inevitable. Here's how to confidently approach the sale of a prestigious property despite an insufficient EPC rating.
What the Energy Performance Certificate (EPC) really reveals about your property
An assessment tool with concrete consequences
The Energy Performance Certificate (EPC) is an official document that measures a building's energy consumption and quantifies its greenhouse gas emissions. It assigns a rating from A, for the most energy-efficient buildings, to G, for the least efficient. Mandatory for all real estate transactions in France, it is now carefully reviewed by the vast majority of buyers.
For a luxury property, this document plays a doubly strategic role. On the one hand, a good score enhances the property's value and reinforces its premium positioning. On the other hand, a poor score raises legitimate questions about future operating costs and anticipated renovations. Wealthy buyers are not insensitive to these issues—quite the contrary: their ability to invest is often accompanied by heightened vigilance regarding the sustainability and profitability of their acquisition.
The concrete obstacles of an unfavorable energy performance certificate (EPC) in the high-end segment
Pressure on the selling price
A poor energy performance certificate (EPC) rating gives buyers powerful negotiating leverage. By highlighting the estimated cost of renovations needed to improve the property's energy efficiency, they can justify a significant price reduction. For properties valued in the millions of euros, the gap between the asking price and the final agreed price can quickly become substantial.
A hindrance to the property's attractiveness
The profile of buyers of luxury properties has evolved. Sensitive to environmental issues and keen to control their expenses, they now include energy performance in their selection criteria alongside location and size. An energy performance certificate (EPC) rating of F or G can therefore immediately exclude a portion of the target market, mechanically reducing the number of viewings and lengthening sales times.
Increasing regulatory constraints
French legislation is evolving towards increasingly strict energy efficiency requirements. Properties rated G have been banned from rental since 2025, and restrictions will gradually extend to classes F and then E. If your property is affected, this regulatory reality is an additional argument that buyers will undoubtedly raise during negotiations. It's best to be prepared.
Improving the Energy Performance Certificate (EPC) before putting the property on the market: the work that makes all the difference
Insulation: the priority project
Thermal insulation is often the most cost-effective way to improve an energy performance certificate (EPC). Roof, exterior walls, floors, windows and doors: every point of heat loss addressed contributes to a better rating. For a luxury property, these improvements must be carried out carefully to preserve the aesthetics and architectural character of the building. High-quality materials and techniques adapted to older buildings allow for a combination of performance and elegance.
Heating and air conditioning systems
Replacing an old oil boiler with an air-to-water or geothermal heat pump, upgrading a faulty ventilation system, installing low-temperature underfloor heating… These new-generation systems can significantly improve the energy performance certificate (EPC) rating. They also represent compelling selling points, reassuring buyers about their future energy costs.
Integrating renewable energies
The installation of photovoltaic or thermal solar panels is an increasingly popular solution in the luxury sector. Beyond improving the energy performance certificate (EPC), it gives the property a decidedly modern and responsible image. Some buyers even see it as a distinctive added value, especially when the installation is combined with an energy storage system or an electric vehicle charging station.

Capitalizing on the irreplaceable assets of the property
In the luxury real estate market, certain criteria transcend energy efficiency considerations. An exceptional location, remarkable architectural features, a landscaped garden spanning several hectares, a unique history or heritage: these distinctive characteristics remain key selling points. An effective sales strategy involves placing these assets at the heart of the sales pitch, relegating the Energy Performance Certificate (EPC) to a secondary and negotiable parameter.
Playing the transparency card
Trying to downplay or conceal a poor Energy Performance Certificate (EPC) rating would be counterproductive. Serious buyers will discover it anyway, and the resulting loss of confidence could jeopardize the transaction. Conversely, proactively addressing the issue—by presenting detailed work estimates, energy savings simulations, or a costed renovation plan—demonstrates your seriousness and reassures buyers about the feasibility of the improvements.
Targeting the right distribution platforms
Visibility for your listing to a qualified audience is crucial. Advertising your property on platforms specializing in luxury real estate, such as Propriétés de Charme, allows you to reach buyers familiar with the specificities of the high-end market and often more open to considering renovation work on properties with strong potential.
The key role of the luxury real estate expert
An experience at the service of your transaction
Navigating the complexities of a sale with a poor Energy Performance Certificate (EPC) requires specific expertise. A real estate agent specializing in luxury properties understands the psychological factors influencing buyers in this segment, knows which selling points to highlight, and can identify the buyer profiles most likely to accept energy-efficiency renovations. This in-depth market knowledge can make all the difference between a long and difficult sale and a transaction completed within a reasonable timeframe.
Tailored support
Beyond simply connecting you with potential buyers, an expert can guide you in choosing the most relevant renovations to undertake before listing, help you determine a fair price that reflects the energy performance certificate (EPC), and develop a tailored marketing strategy with you. Every luxury property is unique; your approach should be too.
A poor energy performance certificate (EPC) doesn't necessarily mean you can't sell a luxury property. It simply prompts you to rethink your strategy, anticipate potential objections, and highlight what makes the property truly exceptional. With the right advice, targeted renovations, and honest communication, your property will find the buyer it deserves.
