The state and the local/district municipality each provided one-third of the renovation costs as a non-refundable subsidy. The maximum amount of subsidy/flat was 400 000-500 000 HUF (€1,140-1,430). The programme focused on improving energy efficiency in prefabricated buildings. The group of eligible actions was gradually increased: while the first years of the programme typically covered modernisation of the heating system or changing of doors and windows, later whole buildings were renovated including insulation or even renewable energy installations. More complex investments corresponded with higher amounts of subsidy. After the mid-2000s the participation of municipalities was no longer obligatory and the subsidy provided by the state increased to 50-60% of the costs. The financial crisis led to lack of resources and the termination of applications in 2009 (by using the already awarded funds in 2011-2012).
