“This list of the most claimed for items we’ve seen in 2020 proves the importance of having a good warranty in place from the beginning of a customer’s ownership with a provider you can rely on to pay out when you need it,” said Lloyd O’Connor, chief executive of Händler Protect.

“All of these items would have caused major headaches for our dealers, had they not been able to contact us and organise a repair for their customer.”
