Label C enforcement can include penalty payments
Offices over 100 m² have needed at least label C since 1 January 2023. At 1 July 2026 the RVO put 84% of office floor area at label C or better, leaving 4% at D or worse and 12% with no label at all. Enforcement can include an order subject to penalty payments. IPLO gives EUR 2,000 a week for up to ten weeks as guidance for an average office building; the authority determines the amount and approach for each case.
