The Motoring Uninsured Loss Recoveries Association (MULRA) has confirmed its commitment to change.
Tesco Personal Finance (TPF) is offering its online customers an incentive to back England's World Cup bid.
The first 30,000 customers to buy a motor or home insurance policy between 22 April and 31 May will get £50 returned if England win the trophy.
And for those who buy both the motor and home insurance online could, the company said, receive £100 back. The refund represents 25% of the average home policy, and 10% of the average motor insurance policy.
TPF's marketing director, Andy Dewhurst, said: "We wanted to show our support for the England football team and create a real wave of support, even with those who are not football fans."
