Hi! If you reach out to our care team we will be able to talk to you about specific costs in the UK. Your first session will be an hour and we usually try to stick with an hour for a while until you learn the skills and become stronger in ERP and then you can definitely move down to 30 minutes. You can also just talk with your provider about it as we are always wanting to work with our members especially when they are self-pay. Our care team will be able to help. Thank you!
