£25 for a private with her usual instructor and then £25 I think for shared SJ lessons every few weeks. Doesn't include facilities hire.
Tbh, lessons are worth as much as you think they're worth. Al would gladly pay more for both her instructors as they're very very good, and both 'get' her and improve her way of riding and thinking in every lesson. Some people round us, we wouldn't pay £2.50 for!
I pay £60 for 2 hours, £50 for 90 minutes or £40 for an hour.
She isn't the cheapest I've used - but worth every penny. I am for one or two lessons a month, depending on finances. Usually 90 or 60 minutes - but she's happy to go over if need be & provides lots of help/support by email/text/phone if anything crops up ... Which it invariably does!
