My car is insured through the AA. Last year, a few months before renewal, I received a letter saying they would match any online quote. When it came to renewal the AA price was more than double the low quotes I found online, so contacted them.
They did not seem to believe the Meerkats quote I'd found (from a well known company) so I had to then write a letter detailing everything that the low-quote company offered and show it against my current policy - the only difference was in European cover which I did not want anyway. The AA did eventually agree to match the quote, so I paid just over £200 - full NCD, £100 excess, two-year-old 1.6 TDi, myself, wife and daughter named drivers. I'm in LL31 post code.
Be interesting to see what they come up with for renewal this coming September. I am waiting delivery on a new car and the online quotes are much cheaper than my current insurance!
Always worth a phone call to the insurer as they (almost) always will reduce the premium without changing the cover.
