Depends on where you are. Around here, anything from £50 to £100 per week full livery including everything but exercise, wormer, shoes and suppliments.
Last year I charged £10/day for full livery, which included grooming and tack cleaning everyday, perparation for hunting (plaiting), provision of shavings, hay and food at cost price (no charge for delivery) but no exercising and he had the cheek to tell me that I was overcharging!! This year I have told him that I will not groom for him at our stables and now he is stuck to get anyone. Don't be a mug to anyone!
