Invisalign treatment cost

I understand that Invisalign treatment cost is based on my smile and how mild, moderate or complex my teeth straightening needs are. However, based on your experience - can you give me an idea of typical cost?

All costs can be confirmed in a formal Treatment Plan after your FREE Smile Assessment. Here at Sherwood Dental Practice, unlike many others we are pleased to offer a fixed price policy on our Invisalign prices. For example, we treat most patients with 14+ aligners so we call this “Invisalign FULL”:

Invisalign FULL £3,995.00
Less £250 deposit
Balance to pay: £3,745.00
