Hi James.
I can give you a perspective from a technology and a little bit on the cultural point of view.
Technologically, the method to deploy a call centre overseas from UK numbers is pretty commonplace these days. This means that, provided your network connections are robust enough, you can pass quite alot of UK traffic to pretty much any location in the world. And yes, there are certainly bargains to be had if you choose to go offshore, Philipines and some countries in South America are being eyed as some of the next "hot spots" to leverage good english speaking staff at very reasonable rates.
As always you want to be mindful as to the type of calls your outsourced centre would be attracting, as some types of calls are more culturally "biased" to a native UK accent than others, especially calls with either a high value, or high personal sensitivity. Fundamentally, you might want to consider specialising in a particular market type... will you be focussing on debt collection, customer care, sales, catalog order taking, outbound, customer surveys or perhaps a combination of these or more... once you can decide your forte, the answers might be a little easier regarding geographical or cultural preferences.
Technologically, though, setting up UK numbers to forward via IP technolgy or SIP into the centre of your choice is pretty easy, and can be quite cost effective too. And sourcing call centre technology in many places these days is not too difficult either. Your best bet might be to identify office space that may have already deployed some telephony infrastructure and just piggy back off of that, or alternatively you can consider investing in your own, it just means start up costs might be higher.
I hope this helps... good luck!
