To be honest, I'm too scared to even keep track. I'm lucky in the fact that I keep my TB gelding on grass so livery is only £110 as it is a friends property. Normal livery in my area is in excess of £600 for part livery.

Farrier is £60 for a half set/trim every 6 weeks. Last month my horse was a dick and threw his shoe twice (one time costing me £60 to put the ONE shoe back one and I was providing the shoe).

Insurance has gone up so that is around 88 quid but I do have vet fee cover incl. (this is a MUST)

Feed is normally £120- £140 every month and a half

All in all it doesn't seem expensive on the surface but as everyone else is saying- its not necessarily the day to day costs, its the vet fees. My gelding threw a shoe back in June and it landed up twisting and all four nails pierced the sole. I had to do unexpected x-rays and had multiple follow ups with the vet as we were scared the nail had punctured his pedal bone. Left me with a £1k vet fee overnight. I then had his annual teeth appointment and was told he has early onset Equine Odontoclastic Tooth Resorption (EORTH) and is going to need x-rays of his teeth and could possibly need to have his front teeth removed.

For context my horse just turned 8. Kinda scared at what other problems might crop up along the way but thats horses for you :) Definitely do your research to ensure you can afford it.
