DD and DP left her rucksack on a train last weekend containing about £200 worth of sports equipment, and it hasn't shown up at Lost property. We need to replace this asap since it is the main competition season. I think it is worth making a claim since it is a lot of money. DP thinks we shouldn't as we will just pay for it with higher premiums. I know our premium is likely to go up if we make a claim but surely not by that much, and it would still be worth making the claim.
Does anyone have any experience of making a claim, etc?
