The UK and EU have different electrical plugs so you will need an adapter at least (and probably not a convertor). Here is a good write up about it from Rick Steves.
For the UK and Ireland, you will need an adapter with 3 big prongs.
For the EU, you will need an adapter with 2 round prongs.
I take a several of the single use ones pictured above and I also have one of these multipurpose adapters, but it buzzes when it is plugged in and the first one that I bought didn’t work when we got to Europe. https://store.ricksteves.com/shop/p/travel-power-adapter
I use it mostly for the USB port. If you really want to buy a universal adapter, here is a site that has a comparison of many of them: https://www.tripsavvy.com/best-travel-adapters-4136335
NOTE: The TV in your room may have a USB port that you can use for charging.
