Mine is covered via my home contents insurance. My wife has had one phone replaced and it was easy. Certainly cheaper than AppleCare. It was a £10 addition I think?
I think my insurance covers up to £10k for items that are stolen or damaged outside of the home. I usually make sure the wording ‘iphones’ is on the policy though as for some reason in the past they have been exclusive to a normal mobile phone?? I haven’t noticed a significant jump in my premium since my wife claimed a few years ago but then we never stay with the same insurer year after year and negotiate the price.Phones are actually normally covered by home insurance anyway simply as an item up to a certain value that leaves the home (normally 2500-5000 pounds covered for items that leave the house such as cameras, watches etc). However, the insurers tend to bump up your annual premium if you ever claim on it. This is why many look for a separate policy.
Mine is covered by my Halifax account but I pay £12 a month for it and it includes AA car cover, home emergency, etc. too.
Excess is £50 for damage and £100 for loss or stolen. Don't know about any £1000 limit.
