There is a 14 day FCA cooling off period, this is from signing the documents, not from taking delivery of the car, where there will be no early termination fees and any administration fees will be refunded.
If a few months down the line, you need to exit your lease deal early, you will need to contact our leasing partners as there will be an early exit penalty fee. As we are a price comparison website, we would highly recommend contacting our leasing partners directly (by clicking get quote on the deal page) to discuss this before taking out a lease as they will be best placed to clarify their cancellation options.
