I think people need to take a step back and not get caught up in media hype.
In almost all cases, the impacted years started from about 2008/2009. It is highly unlikely that any redress is due for anytime before 2008.
The main issue is a mortgage was not reverted to a contracted tracker rate AFTER the end of a fixed rate agreement.
So if you fixed for 3 years in june 2006, your impacted date is June 2009 - NOT 2006 and not when you started a mortgage.
Also in 2006/2007 and half of 2008 the tracker rate and standard variable rate was almost identical, so even if impacted in 2006, the level of impact was minuscule. It was only from mid 2008 that a noticeable divergence appeared.
So, see when your fixed rate ended to find your impacted date.
