Don't expect to receive any cashback from this insurer!
I took out a car insurance policy with Tesco Bank car insurance. They were advertising £45 cashback to new customers on Quidco at the time. Weeks on, the cashback still wasn't showing as tracked, so I contacted quidco. They told me I had to wait 4 months before they could investigate.
After this time, I contacted quidco again, who started an investigation with Tesco Bank which took about 2 months to complete. Tesco Bank declined to pay the cashback despite the fact my quidco account showed I had gone onto the Tesco bank insurance page through their site just a few minutes before I took out my policy!
To be fair, Tesco Bank was competitively priced so although I was annoyed, I didn't feel I'd been ripped off as much as I would of had there quote been more expensive than other insurers and I had just been using them for the cashback, but I would not advise taking out a policy with them expecting to receive the cashback!
