I have had my car insurance with Admiral for two years and was just about to renew for my third year. Last year I upgraded to a new car and paid around £800-900 for my car insurance. Halfway through the year Admiral asked me if I wanted to plug in a black box in my car and drive with it for 3 months to see if I could get additional discounts. I accepted the offer and three months later I received an e-mail saying "Congratulations, you are one of our safest drivers" and that I would receive a discount in my renewal. The renewal came, and shocked me with an invoice of £1800! Instead of giving me a better price after yet another claim free year together with the black box discount, they bumped up the price with almost £1000! I went on to a comparision site to see if I can find a better price elsewhere. Admiral once again came up as the cheapest and the quote was now £888 (around the same as I paid last year, before driving with the black box). The customer service agent at Admiral added this quote to my account but was not able to help me with any information on the black box discount. At e-mail conversations with customer service later they simply told me "the black box discount is already included" despite me telling them over and over again that this price is one that I found myself online and it has nothing to do with my black box. So to re cap: I left Admiral due to their unreliable pricing structure, them wasting my time with the black box and their very poor customer service. I found an even better deal with Aviva (that wasn't visible when I compared the market).
