GSI Insurance or Hastings Direct mate.
GSI won't be on comparison websites but give them a call, their customer service is top grade and they'll do what they can to give you a good quote. Beat ALL other quotes I had previously by miles and no need to haggle either.
Failing that, Hastings Direct seem quite new drivier friendly. They are on comparison websites though, so don't waste your time on their website or calling them, get on comparison websites - don't give them your number though, or 20 insurance companies WILL stalk you for 20 weeks.
HTH.
