Energy label E: what does it mean and how can you improve it?

Introduction

Contents

What does energy label E mean?

Energy label E corresponds to an energy index between 2.01 and 2.40 and is the third lowest category. Homes with an E label are poorly insulated and consume a lot of energy. They are often characterized by:

  • A high energy bill
  • An outdated central heating boiler
  • Hardly any insulation
  • Single or partially single glazing
  • Year of manufacture before 1974

These labels (E, F, and G) fall into the orange/red category: they have very high energy consumption. Homes with an E label therefore score less well on the housing market and often yield less when sold or rented.

Requirements for energy label E

Homes with energy label E consume between 290 and 335 kWh per m² per year. This is considered an unfavorable energy label. Fortunately, simple insulation measures—known as "quick wins"—can quickly bring about improvement.

How do I improve an E-label?

There are many good reasons to improve a poor energy label:

  • A better insulated home is more comfortable in winter and summer.
  • Your energy bill will decrease significantly
  • Your home will increase in value
  • You contribute to lower CO₂ emissions
  • You are making your home future-proof in line with the 2030 regulations.

Possible measures to improve an E-label:

  • Optimizing facade, roof, and floor insulation
  • Installing double or triple glazing
  • Installing a heat pump
  • Add solar panels

Even one of these measures can immediately improve your label. With a combination of insulation and sustainable energy generation, you can often quickly progress to label D, C, or even B.

Renewable Partners helps you with this by providing a personalized sustainability plan.

What is the difference between energy label A and A+++?

The difference lies mainly in the degree of insulation and the proportion of sustainably generated energy. An A label can be achieved with good insulation and an efficient installation. For A+++, more is needed: a large proportion of the energy must be generated sustainably, for example with solar panels and a heat pump.

What requirements must my home meet to qualify for energy label A?

The energy label is determined based on the fossil energy consumption of the home, expressed in kWh/m² per year. For an A label, this value is between 105 and 160 kWh/m² per year. With good insulation, an A label is easily achievable. Homes built after 1991 often already have sufficient basic insulation to fall into this category. Solar panels are therefore not necessarily required to achieve an A label.

What are the benefits of an A label?

  • An A-label home is excellently insulated.
  • You enjoy greater living comfort and lower energy bills.
  • You are contributing to a better climate.
  • Many banks offer interest rate discounts on mortgages for homes with an A label (average 0.1%–0.2%).
  • With an average home value of €387,000, this can amount to savings of €500–€1,500 per year.
  • I want to register my energy label!

    While my energy label doesn't matter at all, new residents are going to renovate the entire house, Nik has still made a thorough and clear report of my old farmhouse. TOP job. Thanks

    The recording was done carefully. All documents and construction dimensions were checked/recorded by the advisor Ronan van der Loo. And good advice was given. He finished the recording within 2 hours.
