I find it frustrating that they are still leading people to believe that WAGO are maintenance free.
Yes, the regs require a maintenance free accessory to have mf on them but the mf is not the technicality, it is the rating of the components inside.
The connectors also need to meet certain tests inside the enclosure they will be used in. wAGO have been singing the "currently undergoing testing" song since November last year. If they haven't passed yet they are unlikely ever to. I think it's time they came clean and confirmed that they do not meet BS7671 mf requirements.
Other than crimping etc, there are currently two options available for MF. Hager mf which can not be covered and LINE mf.
