MARTIN Lewis has issued a warning for mortgage holders following a huge rate hike.
The money saving expert hosted a mortgage special on his Money Show on ITV this week.
It comes after interest rates spiked earlier this week to their highest level in 15 years for an average two-year fix.
The average rate on a two-year fixed mortgage soared again, this time to 6.66%, the highest its been since 2008.
It means that people coming to the end of a fix could be facing higher bills when they get a new deal.
