I can connect from Maine to my old school in NJ with a VPN connection. From there I can browse Russian or BBC porn, and as far as those servers know I am in NJ, not Maine. It's just "a box" that takes connections on one side, sends them out (and back) the other side, on different IP and apparent location.
I really use it to connect to the school's internal-only servers for data access. In that case they can back-track to the VPN to me, and I have to Authenticate to use the VPN.
I have used it when another forum's hosting had an error in its connection tables. I could NOT connect from Maine to Michigan. I could however connect from NJ to Michigan. Some link from NY to VT wasn't in the routing tables.
That would not help if there was a Brits-only resource--- NJ is clearly outside Britain.

It seems you face a "no Brits" problem. There may be a subscription or access fee (but they should say so). They may want to force you to wait until it comes on the broadcast service. It may be bureaucratic stupidity, or even bad filter rules.
A non-Brit VPN would make you "appear to be non-Brit" and (since pucho sees it) a US-based VPN would work.
But the old days of good free VPNs seem to be gone. There are a few, but with such low limits that you would probably go over quota watching movies through a free VPN. Enough people want to mask their IP and location that demand must be overwhelming. Good (business grade) VPNs are readily available at a price.
