That's useful to highlight, as £1000 per condition can quickly be exceeded.
Our very own Ginger mog was hyperthyroid. I say "was" as he had Iodine-131 treatment a couple of months ago, his follow-up blood test results just came back and he now has normal thyroid function (from being hugely hyperthyroid). He couldn't tolerate the alternative treatment of daily medication (meds made him very sick- vomiting until exhaustion), and by the time we got him in for treatment he was like a bag of bones in an unkempt fur coat (in spite of eating at least twice the recommended amount of food)- he was so bad our vet rang around and got us on waiting lists for treatment with the highest priority. Whereas now after the treatment he has put muscle mass back on and his coat is good again. In 2 months gone from weighing about 3.5 kg to 5.25 kg. Much happier and healthier moggie- he's actually a big cat so about normal weight now.
The cost was considerably more than £1000 for the treatment as it needed the work-up to deal with for any other issues before treatment- which involves 2 weeks isolated in a specialist unit in a vet hospital. We are with PetPlan and they paid for all the treatment in full and promptly. They were not the cheapest cover about but in hindsight we're glad we used them.
As ever, (a) reading the small print and (b) understanding how much vetinery treatment can cost for some conditions is important.
