I changed my lot from M&S to Healthy Pets when their premiums shot way up and they removed the zero excess option. I didn't find the amount they were charging was justified by the cover they were offering, it's not that much better than HP (for me). So far I've found HP to be great, I've put in one very big claim for Rodaidh's luxating patella treatment which was split between two vets and they paid up promptly and with no hassle. The cover suits really well for my circumstances although I know that if for whatever reason one of the dogs did need more than 5000 pounds worth of treatment I'd be able to make it up from savings etc.
