EP-Online: the Dutch energy label register

What is EP-Online?

EP-Online is the register in which every certified EP assessor records an assessed energy label. RVO maintains it on behalf of the ministry. Civil-law notaries, estate agents, tenants and municipalities consult it to check whether a property has a valid label.

Registration is the moment a label truly exists. An assessor can produce a report as polished as they like, but without registration in EP-Online you hold nothing at a transfer.

What does it hold per address?

• The label class, from A++++ down to G.
• The registration date, meaning when the label was recorded.
• The expiry date: labels are valid for ten years.
• The construction year and building type.
• The calculation method: NTA 8800 from 2021 onwards, the older method before that.

Look up your own label

You can do that below, with a postcode and house number. We fetch the data straight from EP-Online and show it unchanged.

My property is not in it

The register holds only valid, registered labels. If your property is missing, no label was ever requested, it has expired, or it dates from before 2015. Expired labels are no longer shown.

That is not a problem as long as you do nothing with the property. When selling, letting or handing over, you do need a valid label.

How to read a registered label

The register shows more per address than the letter alone. This is what the fields mean:

• Label class: the letter, from A++++ to G.
• Primary fossil energy use in kWh per square metre per year: the figure the letter follows from. Labels from before 2021 do not have this figure; they were calculated with the old method and stay valid until their end date.
• Inspection date and registration date: the inspection is the assessor's visit, the registration the moment the label officially exists. The ten-year validity runs from the registration.
• Valid until: after this date the register no longer shows the label.
• Certificate holder: the assessor's company that filed the label. That is where you go when something is wrong.

Is the label wrong?

An assessor files a label on the basis of what they saw and could prove during the inspection. If you think it is too low, these are the steps:

• Ask the assessor to explain. The difference is often insulation that could not be proven. With invoices or photos the assessor can revise the inspection and file again.
• Have a new label assessed. A newer label automatically replaces the old one in EP-Online. That is also the route after a renovation: you do not have to wait until the old label expires.
• File a complaint with the assessor's certification body if you suspect the inspection was not done by the rules. Every certified assessor falls under such a body; its name is on the certificate.

You cannot change anything in the register yourself, not even as the owner. That is deliberate: only a verified inspection may produce a label.
