Yes you will need to use a VPN that will give your internet connection an IP address for another country as in this case the UK

A Google search has returned sooooo many results it's crazy how many options you have

Watch out for free VPNs youa re asking for trouble

How would I do this on a smart TV though

Well the Smart TV must be connected to the internet correct? As above your internet connection must have an IP address for the UK

Have you done any research online?

Some routers will let you establish a site to site VPN. Otherwise you can use a computer on the network as a gateway, if you google "linux vpn gateway" you should get some useful advice.

It's not hard, but either option will take some effort. Bypassing geo restrictions is not something I personally bother with, the local services are now good enough, and it is questionable from an ethical and legal standpoint.
