Most of time, in order to watch UK TV, you need to connect to a VPN server in UK so you can get a UK IP. Hidemyass is from Britain and they have many VPN servers in their home country
. You can also try PureVPN
, but I find it is too expensive. Personally I won't spend more than $60/year for a VPN service considering there are free VPN services. You can also checkout VPNVanish. No matter which VPN provider you choose, make sure they have VPN servers in U.K. Also most of them offer free trials so you can try a few of them and see which one works the best for you.
