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

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.
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.

I have experienced Renewable Partners as a reliable and professional party in the field of sustainable energy. They think along well, are transparent in their communication, and deliver customized solutions that really meet the need.
Professional and readily available for questions. I am very satisfied with the service and can recommend the company. Kind regards,
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 energy label inspector is a highly skilled professional who knows his trade. We were helped well and quickly with his advice. The reactions of this company are praising the price, the lowest, and the service, downright TOP!
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.
