Not me, mine was nearer 50%
I'm with IAM Surety, so I told them it wasn't good enough and come back with a better offer.
Then I consulted Alexandr.... there were some significant savings to be had if I shifted insurer. So, I passed the Meerkat information on to IAM Surety and they matched the lowest quote
I did tell them I wasn't happy about the initial quote, and told them in the future I'll just switch, but it was a lot less hassle to stay with them (and TBH the cover is better than my other quotes). All in all about 10 minutes work to save a hunk of cash.
Today I received my Car Insurance from IAM Surety, they are only £5 over the lowest quote on the Meerkats, so it looks like they have listened.
