Just to add, NCI have refused to pay for any of Fred's treatment and when it came to Benji's policy they wanted £851 to insure him which we can't afford, so he is uninsured now. We are lucky our vets are so good and will let us pay in instalments to cover the bill (£2,500).
Have been generally unimpressed with NCI and not been happy with their customer service. Simple things like when they phone me the number of security questions you have to answer is ridiculous. Would not recommend them at all.
