The usual pattern for those learning to drive is to take a two-hour driving lesson once a week.
Subject to availability I’m happy for you to book more than one lesson each week. 90-minute lessons are available by agreement.
My normal working hours are Monday to Friday, 8am to 6pm. I do recognise that, for many people, availability for driving lessons can vary from week to week. I’m keen to work with customers whose availability varies to find ways to avoid long gaps between lessons.
