Over a third (31%) of homeowners are on a standard variable rate mortgage compared to 23% in January 2009. 29% of these homeowners have no plans to change from their SVR, a 4% increase from May 2009.
Unbiased believes that homeowners are refraining from remortgaging to a fixed-rate deal until the base rate starts to rise.
The professional advice website added that fixed-rate deals need to be very low in order to attract homeowners, as the average amount homeowners are prepared to fix has decreased over the past year from 4% in January 2009 to just 3.3%.
Karen Barrett, chief executive of Unbiased, said: “With the number of mortgage deals slowly increasing homeowners need to make sure they are not missing out on getting the best deals before the base rate starts to rise again.
The research was carried out on just over 2,000 adults.
