What is an energy advisor?

An energy advisor is a highly specialised professional whose job is to analyse, manage, and improve energy use in any setting, whether it is a private home, a large industrial facility, or a public institution. Their main role is to act as a strategic consultant, helping users navigate the complexity of the energy sector while always aiming to strike the right balance between necessary comfort and the lowest possible cost. An advisor is not simply someone who looks for a cheaper tariff, but an expert who understands how a property’s systems interact with the energy market.

Today, this concept has evolved into digital advisory services. It is no longer just about a professional physically visiting a property. Now, tools such as ‘InfoEnergía: your energy advisor on your phone’ allow any customer with a contracted capacity under 15 kW to have a virtual expert available 24/7.

What exactly do they do?

The work of an energy advisor begins with an in-depth diagnostic phase, during which they examine consumption patterns and assess the condition of the installation. They break down utility bills, check that climate control and lighting systems are working properly, and identify critical points where energy is being wasted. Once these issues have been identified, the advisor prepares a tailored improvement plan, which can range from minor changes in daily routines to investment proposals for more modern and efficient technologies. Ultimately, their goal is always to improve energy efficiency, champion sustainability, and reduce environmental impact.

How are they different from other technical profiles?

Energy advisors are often confused with installers or electricians, but while their roles are different, they are also complementary. An electrician ensures that an installation is safe and functioning properly, while an energy advisor focuses on making that same installation efficient and cost-effective over time. An energy advisor takes a broader view, combining knowledge of thermodynamics, current regulations, the electricity market, and renewable energy. This allows them to propose solutions that go far beyond a technical repair. Most importantly, they must be able to translate complex technical concepts into simple language to make sure that the client fully understands the situation and can make informed decisions.

What kind of problems do they help solve?

This expert can be the solution when operating costs start to affect competitiveness, or when a household struggles to maintain a comfortable temperature despite high energy bills. They deal with issues such as poor thermal insulation, outdated heating and air conditioning (HVAC) systems, or having more contracted power than is actually needed. They also act as an intermediary, helping clients understand energy regulations and manage potential grants or subsidies for improvement projects.

What does an energy advisor do?

The role of an energy advisor is wide-ranging and focuses on giving clients greater clarity and control over their energy spending.

Analysing energy consumption and bills

An energy advisor uses measurement tools and management software to understand how, when, and where energy is being consumed. They review billing periods, identify unusual demand peaks, and check whether power and energy charges accurately reflect actual usage. To perform this analysis yourself, it is essential to have an itemised electricity bill explained with total transparency. This will help you avoid surprises and clearly understand every charge.

Identifying savings opportunities

Through detailed comparisons, an energy advisor can identify where a property has room for improvement. In the residential sector, digital tools allow you to compare your energy consumption with that of similar homes, helping determine whether your spending is reasonable or if there are anomalies. Identifying these savings opportunities is the first step toward lowering energy bills without sacrificing comfort.

Recommending improvements

Following the analysis, the advisor provides a clear roadmap with practical recommendations. These may involve low-cost measures, such as adjusting usage schedules, or more substantial upgrades, such as replacing older appliances with more energy-efficient models. They may also recommend improvements to the building envelope or upgrading lighting systems to LED technology, always calculating the expected return on investment.

Guidance on renewables and electrification

In the context of today’s energy transition, an energy advisor plays a key role in guiding users toward self-consumption. They assess the feasibility of installing solar photovoltaic panels or wind turbines, analyse the integration of air-source heat pump systems for heating, and advise on the installation of charging points for electric vehicles. If you are just getting started in this area, it is essential to first understand what self-consumption means and how it can transform your relationship with energy.

When does it make sense to hire an energy advisor?

While a full professional intervention is not always necessary, there are situations where expert support can make all the difference in long-term savings.

If your energy bill goes up and you don’t know why

When your bills increase significantly even though your household lifestyle has not changed, it is usually a sign that something is wrong. An energy advisor can determine whether the issue is a hidden technical fault, a malfunctioning appliance, or an energy tariff that is no longer competitive. In these cases, we recommend reviewing our electricity and gas tariffs to find the option that best suits your new habits.

If you are renovating or replacing your system

A renovation is the ideal time to involve an energy advisor in the planning process. They can help you choose materials that maximise thermal insulation and high-efficiency climate control systems from the very beginning of the project. At this stage, it is essential to determine how much power your home actually needs using a power calculator to avoid paying for capacity you won't use.

If you are considering solar panels, aerothermal heating, or an EV charger

Before making a major investment in renewable energy, a professional feasibility study is essential. An energy advisor will assess the roof, orientation, current consumption, and future needs in order to size the installation correctly and avoid costly mistakes.

Energy advisor vs energy auditor: what’s the difference?

Although both terms are sometimes used interchangeably, they differ in their approach and purpose.

Energy advice is broader and more practical

Energy advisory services are not a one-off event, but an ongoing support process. An energy advisor doesn’t just stop at a diagnosis; they propose practical solutions, help manage suppliers, and follow up on results to ensure savings are maintained over time. This is a proactive role focused on continuously improving day-to-day efficiency.

Energy audits follow a formal framework

An energy audit is a regulated technical procedure that is often mandatory for certain companies. In essence, it is a comprehensive study that produces a detailed report on a building's energy consumption at a given point in time. Compared with traditional energy advisory services, it is more of a ‘snapshot’ used for regulatory compliance.

When do you need one or the other?

A residential customer will typically need an energy advisor (or a tool such as InfoEnergía) to resolve everyday questions and optimise energy bills. An energy audit is necessary when required by law for large facilities or when a formal technical certification is needed to access industrial subsidies.

How to decide whether energy advice is worth it

To evaluate the need for this service, users should look for signs of inefficiency in their own environment.

Signs of inefficient energy consumption

Indicators such as cold walls, unusual boiler noises, or an energy bill that exceeds the average for similar households are clear signs of inefficiency. Tools such as InfoEnergía can help identify these warning signs free of charge, allowing users to visualise their energy use in detail and compare it with their surroundings.

Potential savings vs cost or effort

It is estimated that customers who use digital energy advisory services save, on average, an additional 10% on their electricity bills. These savings can be achieved without major investment, simply by adjusting habits or following the personalised tips provided by an ‘energy advisor on your phone.’

Questions to ask before hiring

Before hiring an energy advisor, ask about their experience, what measurement tools they use, and whether they can explain their conclusions in simple terms. A good energy advisor should give you full control over your energy use.
