My best tip is to get used to early mornings! You will generally need your own wheelbarrow, shavings fork, broom, feed buckets, dustbins for feed, grooming kit and a big bucket for water. Trugs are great, you can get them much cheaper in B&Q or poundsaver shops. I have two large ones, one for water and the other for baths. I have 4 smaller ones, for feeds. I make them all up so if I can't get down there I can ask a neighbour to feed and it's just a case of picking up a made up bucket. Haynets, get at least 2 so you can hang one up and have another made up on standby for replacing in the morning. Buy a nice strong lockbox, the biggest you can fit in your space, to keep your bits in. If big enough, you can keep your saddle in there too, I do. A big strong lock, with extra keys. A cowboy stetson for wet weather, plenty of cheap latex gloves for the mucky jobs.
