Data Providers and API's

Hello gentlemen. Does anyone have any recommendations for a data provider in the UK? I need historic and streaming tick data but also a means, such as an api, whereby I can access live data programatically. Anyone ideas? I've already had the CQG api up and running but can no longer use that so I need something cheap and cheerful as replacement.
Thanks!

gone for esignal in case anyone wants to know! haha
