Skyrocketing service charges are blighting the lives of many people living in leasehold homes in London and the east of England. As the government considers reform of the leasehold system, housing reporter Tarah Welsh investigates whether some property management companies are engaging in sharp practice and overcharging. From a family home damaged by a leaking roof to a flat where the service charge is higher than the mortgage payments, this programme examines if leaseholders are getting a fair deal.
