My daughters first year insurance went from £1,450 down to £850 with just a few clicks. By adding my wife and myself to my daughters policy as named drivers reduced it by £550, and then changing the start date reduced it by another £50.
This year was even better as it came in at just £700, but this time doing the opposite worked in our favour. By removing ourselves from her policy reduced the premium by £200, so her second year of driving she's only paying £500, plus using Quidco the cashback site my daughter will receive £40 cashback, now that cant be bad.
