I was PIC and pilot flying; SIC was pilot monitoring and handling radio communication. The Approach Controller issued a speed restriction and gave us a warning for wake turbulence. Shortly after he gave us a heading to intercept the final approach course; and cleared us for the visual approach. The Controller issued frequency change to Tower; just as we encountered wake turbulence. We discussed the issue and adjusted our glide-path accordingly to avoid another wake turbulence encounter. We completed the before landing checklist items and on the roll-out realized that we did not switch to Tower for our landing clearance. Distraction and lack of effective CRM resulted in missing required ATC communication during a critical phase of flight. The current approved checklist for the aircraft does not mention landing clearance on the 'Before Landing' checklist.
Piaggio 180 Captain reported landing without a clearance after they were distracted by a wake turbulence encounter.
