Just had to update both my address AND vehicle details having moved house and replaced the daily driver. Was expecting to get stung for an admin fee of ~ 25 sheets (had to shell out with other companies in the past) plus poss. higher premium for the remainder of the policy... ...But they didn't charge me a penny to update the details, plus they even covered both my old car and the new one for a week for free! (collected the new motor before the old one went).
