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

Homes with energy label F are among the most energy-inefficient homes in the Netherlands. It is the second-worst energy label, just above energy label G. These labels are often referred to as orange and red because of their very high energy consumption and the unnecessarily high energy costs that come with it.

In addition, an inefficient energy label usually results in a lower property value and slower sales. Renewable Partners explains exactly what an F label means, what conditions apply, and how you can make your home more sustainable in a smart and affordable way.

What does energy label F mean?

A home with energy label F has hardly any energy-saving measures in place. As a result, a lot of heat is lost and heating costs are high. The comfort level in the home is often low due to drafts and large temperature differences.

Example of a typical F-label home:

  • Year of manufacture 1946–1964
  • No insulation or only minimal insulation
  • Single or partially single glazing
  • Outdated boiler
  • A lot of drafts
  • High heating costs

Due to its high energy consumption, an F label is clearly unfavorable. Homes with this label are difficult to keep warm and consume much more energy than necessary.

Requirements for energy label F

A home with energy label F consumes between 335 and 380 kWh per m² per year. That is roughly 1.5 to 2 times as much as a home with energy label C. This makes the F label the second worst label in the energy label classification.

How do I improve an F label?

The good news: an F label actually offers plenty of room for improvement. Often, relatively small and inexpensive measures can quickly yield results.

Possible quick wins:

  • Installing draft strips
  • Applying radiator foil
  • Hanging thick curtains
  • Improve door seals

Larger, highly effective measures:

  • New HR boiler or hybrid heat pump
  • Facade or cavity wall insulation
  • Roof insulation or floor insulation
  • HR++ or triple glazing
  • Solar panels

With these measures, you can not only go from F to E or D, but often even towards a C, B, or A label. Some homes can even make the leap to A, A+, or higher with solar panels and insulation. Improving your energy label also saves you money: your energy bill goes down, the value of your home goes up, and your living comfort improves significantly.
