In Chelsea's case, these periods were two, three, five, seven and 10 years.
Does Chelsea Building Society offer the best mortgage deals?

The average number of times a lender made it into a table was 16, but Chelsea failed to feature at all, meaning it is unlikely to offer the cheapest rate on the market. (Data source: Moneyfacts.)
