In my area, all you need to do is express your intention to your midwife and they will sort their side of things.
My midwife mentioned a cheap shower curtain being good protection for flooring particularly with a water birth.
You can hire a pool. Ask your midwife first, I know our local midwifery led unit has a couple they hire out for a very reasonable charge (you obviously get a brand new liner).
You can have gas and air at home, the midwives will supply it. You can also hire TENS quite cheaply.
Other than that I would be thinking about whether you want any other kit, birthing ball, beanbag, nice candles.
I've never had a home birth but I've seen them into you have to talk to your mw about it sometimes they will just say they don't do it in your areas and you have to hire a independent midwife and you can rent a bath, heater, and cover for the top and floor. The midwife that you have/hire you should be able to get the kit off sometimes its free other times it isn't she will bring gas and air and pethadine with her x
like Evie said, you can hire birth pools, can't remember any sites tho! Value shower curtains are ace cos you can just throw them down to protxt things! A torch, useful if they need extra lighting to "certain" areas! When you discuss it with your mw they'll talk you thru it all, they drop you off a home birth kit which contains all they'll need, think it's after 37 weeks they do that!
