Mortgage interest relief

I have searched the forums and the revenue web site but I cannot find the information regarding this.I am married and was a second time house buyer in aug 2008.I am trying to find out what level of mortgage interest relief and for how long am I entitled to it?

There ya go, should be under mortgage intereste relief rates, about a third of the way down the page.

Thanks for that..i had missed the link to relief rates.
