How much does energy efficiency really affect property value?

LT Immobili & Design 16 July 2026

Energy efficiency and property value: why today’s homes are assessed not only by what they offer, but also by how efficiently they perform.

For many years, a property’s energy rating remained largely unnoticed.

It appeared on the Energy Performance Certificate (EPC), was included in property listings because legislation required it, but rarely influenced a buyer’s final decision.

Today, the picture is entirely different.

Rising energy costs, increasing environmental awareness and evolving European regulations have fundamentally changed the way people evaluate a home. Energy efficiency is no longer a purely technical specification; it has become one of the factors that helps define a property’s overall value.

Of course, it is not the only one. Location, surroundings, construction quality and overall condition remain equally important. That is why, in another article, we explore how much location really matters when determining a property’s value, highlighting the balance between all the elements that influence the market.

The way people buy homes has changed significantly.

Not long ago, most buyers focused almost exclusively on the purchase price.

Today, the questions are very different.

How much will it cost to heat the property?

What will the running costs be over the next ten or twenty years?

Will major energy upgrades be required?

These are now common questions during viewings, and they often shape a buyer’s perception of value before any negotiation even begins.

It is therefore no surprise that highly energy-efficient homes attract stronger interest from the moment they are launched on the market, while less efficient properties often require longer selling periods.

This reflects a broader evolution in buyer expectations. Modern purchasers increasingly seek homes that offer comfort, efficiency, quality construction and lower long-term operating costs. We discuss this shift in greater detail in our article on what buyers are really looking for in today’s property market.

A common question is whether a highly energy-efficient property is automatically worth more.

As with most aspects of the property market, the answer is more nuanced.

There is no universal percentage increase, because value is always determined by a combination of factors including location, construction quality, condition, market demand and the surrounding environment.

What we consistently observe, however, is something equally important.

Energy-efficient homes are perceived as safer investments, more future-proof and less likely to generate unexpected costs. As a result, they attract greater interest, lead to smoother negotiations and often reduce the need for significant price reductions.

In other words, energy efficiency does not always increase a property’s absolute value, but it frequently improves its ability to sell successfully.

And that distinction is significant.

This is precisely why simply listing a property is no longer enough. Every home requires a carefully designed marketing strategy that highlights the features that genuinely make it stand out. We explore this concept further in our article Why Do Some Properties Receive Viewings but No Offers?

Discussing energy efficiency does not mean that lower-rated properties have lost their value.

It simply means that the market is evolving.

Homes with higher energy consumption now require more thoughtful positioning, realistic pricing and a well-planned marketing strategy.

This is reinforced by evolving legislation, increasing attention from mortgage lenders and growing awareness among buyers regarding long-term ownership costs.

For these reasons, negotiations involving less efficient properties often become more complex and benefit from professional guidance from the very beginning.

In many cases, what initially appears to be a pricing issue is actually a matter of perceived value. We examine this in more detail in our article Why Do Some Property Transactions Collapse at the Last Minute?

There is one aspect of the property market that no certificate can fully measure.

Perception.

An energy-efficient home immediately conveys comfort, quality, modern living and reliability.

It suggests a property that is ready to enjoy and designed to provide lower running costs and greater peace of mind.

Conversely, a home perceived as inefficient may create uncertainty before buyers even examine the technical details.

And it is often this perception that shapes purchasing decisions during a viewing.

Because people do not simply buy square metres.

They buy comfort, confidence and a better quality of life.

Every week we meet homeowners who believe their property’s value depends solely on its location or size.

The reality is more complex.

Today’s market increasingly rewards homes that combine comfort, construction quality, energy efficiency and a carefully planned presentation strategy.

For this reason, every valuation should begin with a comprehensive analysis rather than relying solely on comparable sales or official market statistics.

Energy efficiency has become one of the factors that makes a property more competitive, but it remains only one part of a much broader picture.

If you are considering selling your home and would like to understand which elements genuinely influence its market value, our advice is simple: evaluate your property through the eyes of today’s buyers, not only through the perspective of someone who has lived there.

Because today, the value of a home is measured by far more than what can be seen.

Increasingly, it is also defined by how efficiently it performs and how well it meets the expectations of tomorrow’s buyers.
