The HP KEYMARK was accepted immediately in France, where the law requires data from ISO compatible certification systems, and it has been included in the BAFA list for subsidies in Germany. It can be also used in Austria, Poland, and Switzerland, where the EHPA Quality Label requirements are recognized: for HP KEYMARK certificate holders, the application to EHPA QL is extremely simple as no further testing is required. The KEYMARK scheme is included in the Czech HP list.
Moreover, the KEYMARK certificate can be used in Finland, Norway, Sweden, Belgium, Italy, Portugal, and Spain, where no certification is required for heat pumps.
Discussion is ongoing for the recognition of the KEYMARK certificate on the Irish Harp List and Denmark’s positive list, and for its acceptance as equivalent under MCS scheme in the UK.
