Yes you DO need the Internet to stream the content. In my experience site WiFi just can't cope with the bandwidth requirements. You could try 4G but that would loose a lot of data.

You have to subscribe to Amazon Prime, but like the firestick, or Google Chrome you still need a good wi-fi signal.
That should have been Google Chromecast, not Chrome.
I use Now TV to stream all my UK TV - it is brilliant and very cheap if you just go for the free channels.
The BBC suggest you need a minimum bandwidth of 2.5MB/sec which you would probably get with 3G and will certainly get with 4G but the problem is likely to be your data allowance as you will use between 50 and 350MB per hour streaming video (depending on the video quality).
More and more cellular data plans are coming along bundle with anything up to 40GB per month and at a fairly reasonable cost. This equates to at least 120 hours of video streaming per month. Of course, if there is a reasonably fast on-site wi-fi connection then you will not be using your cellular data allowance at all.
For those wanting to watch TV by internet abroad, it is worth remembering that from 15th June 2017 you will be able to roam free of charge in the EU, including use of any data plan you may have.
Last, but not least, watching UK TV outside the UK will require a SmartDNS or VPN connection.
