Sorry to hear your bad news.
The insurance companies seem to be trying to improve their profit levels by removing risk across the board at the moment. I have heard a few comments similar to this but it is no surprise. I don't think it is totally unfair. My Aero S2 only cost me £200.45 this year including PNCB, loan car, 6000 miles. That's good for £45,000 of risk.
Insurance for young drivers is horrific so everyone puts them on as named drivers. This is then causing problems so the insurance companies are acting in the manner you describe.
They see it as you cheating by hiding a higher risk driver under your name. In effect they are right however given there are no other ways of doing it in a sensible manner it is a problem of their own making.
I renewed my insurance yesterday. Same company and car mix but it had gone up from £1400 to £1800 which made me spit the dummy as well. My one remaining speeding penalty expired it's five years. I got three other quotes and then called them and they took it back down to £1480. Well that's a win for customer service isn't it
