This is the second year where Admiral has tried to double my existing premium with their auto renewal service. In 2015 they pushed through an increase from £960 to £1904 before I noticed. I immediately cancelled the policy when I saw the charge on my credit card. I reapplied as a new customer and my premium dropped to £999. This year they tried the same thing and quoted a renewal price of £1873. By now my loyalty and patience had worn out - I moved to a competitor for a premium of £870. I suggest the best way to avoid this auto renewal con is not to take insurance with Admiral in the first place
