Hi maria89 L,
If you are providing digital services to UK customers then there would be a requirement to register for VAT once the £85K threshold has been breached.
This would mean that you would not need to register for VAT and therefore not charge VAT to UK customers,EU customers or customers outside the EU.
However if you are supplying non business customers within the EU then there would be a requirement to register for VAT in the countries where you make these supplies or alternatively register for MOSS in a member state of your choice.
Please see the guidance below;

Digital portals, platforms, gateways and marketplaces
Thank you.
