Although most of the UK media sites block access based on your location, there is a way to watch British TV online from anywhere. It involves using a technique similar to a proxy or VPN server to hide your IP address which is how media site like the BBC, ITV, Channel 4 and Channel 5 restrict access.
This video demonstrates how easy it is to watch UK TV abroad simply by using software which controls and secure your connection. The same software comes complete with servers all across the planet so you can also use it to watch US TV, Canadian or European TV stations plus many more.
There are some options to change your IP address without a subscription service too. You can find lots of proxy servers available online for free, just google 'proxy lists'. There are drawbacks with these though, the majority are far too slow for streaming any sort of media content and many are also infected with spyware, adware or viruses. Make sure your AV software is up to date and never access things like banking sites or Paypal when connected through these free servers.
For those who do travel a lot and need to access secure sites through Hotel and other unsafe Wifi connection, you should always turn on encryption to hide your credentials when you connect. The software above has a little slider to move the encryption levels from nothing to high.
