Would that have been down to brexit?

No, not in the slightest. In what way have the EU ever regulated broadcasting in member states? They certainly never did with anything broadcast from the UK.

Many international channels broadcast to Europe are uplinked from the UK, so are regulated by Ofcom.

Brexit had a big impact on Broadcasting. Previously a broadcaster could be based in/uplinked from the UK and target any other EU country with just an Ofcom licence. That is no longer possible. 

As explained above, broadcasters based in the UK but targeting the EU have had to take out new licences in any EU country, and in most cases have also moved their uplink out of the UK so as not to need an Ofcom licence in addition to a licence from their EU country of choice. 

Many smaller channels and nearly all radio stations were removed from the Sky EPG in Ireland a few weeks before Brexit due to licencing complications.
