 Trustindex verifies that the original source of the review is Google. The 3 guys I have had to my Equestrian Centre over the last week have all been really nice people.We have a dog with nervous aggression here that I always make sure is muzzled & out way when different people come on to yard.Unfortunately the 1st guy gave me no prior warning & didn’t know was meant to but I think I just assumed when told turn around was 10-14 days when initially made booking that someone would call on day coming.Although it was bit manic on arrival he was really nice & didn’t make big deal over grumpy dog.🤣I have since had another 2 guys out & both have rung before hand so could put him away.Thanx guys.Good service.x

 Trustindex verifies that the original source of the review is Google. Fantastic service from Martin when our septic tank was emptied this week. He was friendly (despite the appalling weather !}, considerate and very tidy - all much appreciated given that our tank is at the end of our neighbours garden and requires access through their property.
5 stars ! ⭐️⭐️⭐️⭐️⭐️
