KBIS! I've been with them for years. They accept foals from 30 days (they will do earlier but the costs are prohibitive for me so I keep everything crossed until they're 30 days old!)
it was a few years ago and I hadn't used them before. I know a lot of people that have just opened up new accounts with them as well. I would have thought that as they are an insurance company they would be open to always taking on new business.....
i have just insured extra cover from NFU for my in foal mare. the foal is under her policy now until it is 30 days old for £10.00 pm . this will cover the foal until then for 20% of the insured cost of the mare. ie: £5000 mare £1000 for the foal. which should cover stud fee, vets fees if god forbid anything goes wrong.
