I’ve heard good and bad about Esure, I was even insured with them one year however I didn't have any claims/accidents so my only contact with them was paying the annual premium up front. Indeed Aviva have been brilliant however my disappointed with their lack of flexibility with respect to mid term premium adjustment (4m into a 12m period). It’s something that will be a consideration when I’m up for renewal.
Ultimately I really wanted to understand how flexible insurers are with something that impacted everyone more or less the same.
