I've been looking around recently in hampshire for livery. The following are all full at the moment
Posh yard with excellent facilities, 5 day full with DIY on weekends = £390pcm
Not so posh yard but still has indoor school 7 day full = £385 pcm
Smaller yard with much more individual attention 7 day full = £440pcm
I'm on the waiting list for all 3, real lack of decent livery round me.
ETS: all those include muck out, change rugs, turnout/bring in, hay/haylage, shavings and hard feed. No grooming in the first two.
I charge £340 per month for a 5 day full livery. That price includes all daily care of horse, hay, straw, basic concentrates, all year round turn out, exercised 3 x per week, daily groom, paddock maintenance, and I think that is everything!
A 7 day full livery is £440 per month.
For a Part Livery which is as above but excluding exercise I charge £260 for 5 days and £360 for 7 days.
I am a small yard with 14 stables and a lovely set up. I am based in Wiltshire.
Hope that helps in giving you an idea of pricing and what is included.
