EU Mutual Recognition ‘Cancelled’ Article 10 of the EU F-Gas Regulation, (EU) 517/2014, requires that Member States give mutual recognition to certification of suitable qualifications from other EU countries, however with the UK now leaving the EU following BREXIT, this is no longer the case. UK F-Gas qualifications are no longer recognised in EU member states.
