is there a list that gives all the voip providers in the Uk and/or can be used in the uk and lists all features and prices

Unless you actually know the voip provider name its actually quite hard to find providers

BT broadband Talk is a voip service ofering free evening and weekend landline calls for anyone using Broadband.

My work now uses voip for its phones and chance there phone number and im 95% sure they no longer use the BT service since changing to voip earlier this year but Im not sure what voip the are now with. They also got a landline number to use to phone out incase the voip service ever gose down.

There is a trade body, the Internet Telephony Services Providers’ Association and you can see their members here:
http://www.itspa.org.uk/members.html
While they are not independent of their members, they do have a Code of Practice for members and also run a Quality Mark scheme, whereby members who self-certify that they meet the criteria can use the logo.
Not on this list are Tesco/Frestel who have just pulled the plug on their customers with little notice and no alternative offer, nor VOIPCheap.co.uk which looks like the current cheapest deal for landline calls.

sipgate.co.uk whom I use are not on that list either.

Nor any of the other Betamax VoIP companies.

I use www.internetcalls.com Have an ordinary number.
This is one of the Betamax VoIP companies. Cheap and excellent - but no customer service

checkout www.localphone.com, they are pretty good
