There are quite a few places! I am not totally familiar with the names but I ride round there and there is yard after yard.
There is South Hill Farm in Stock, several in and around Park Lane, Billericay including Shelley Brooks with the water treadmill, there is De Beauvoir farm and Bellhouse stud on the main road through Ramsden, Buckwyns in Billericay is very popular, Runningwell isn't very far either.
I think if you drove around those areas you will find so many options that aren't usually advertised, otherwise if you post on Essex horse riders on facebook there are always posts of little yards around that area coming up.
