EPC 2030 in Flanders: Renovation Timeline

The renovation obligation in Flanders

Since January 1, 2023, Flanders has introduced an energy renovation obligation for buyers of residential property. It is the most ambitious measure in Belgium regarding the energy transition of the housing stock.

The timeline

• 2023: Every buyer of an EPC E or F property must achieve at least label D within 5 years
• 2028: Expected extension to EPC D properties (target label C)
• 2030: Target label C minimum for the entire Flemish residential stock
• 2050: Target label A for all dwellings

What works to achieve label D?

For a property rated E or F, typical works include:

• Roof insulation (if not insulated): gain of 1 to 2 labels
• Replacing single with double glazing: gain of 0.5 to 1 label
• Replacing the boiler with a condensing model
• Partial wall insulation

Average budget: between 15,000 and 40,000 EUR to go from E/F to D.

Penalties

Penalties for non-compliance are not yet definitively set, but the Flemish government plans administrative fines and loss of certain tax advantages (such as the reduced 3% registration duty rate).

Financial support

To support this obligation, Flanders offers the Mijn VerbouwPremie program with substantial subsidies for each type of work. The EPC Label Premium offers an additional bonus of 2,500 to 5,000 EUR for households achieving label A or B.
