Drain Doctor chairman Freddie Mitman said: "The customers already enthuse about the company's service standards. Couple this with accredited training to City & Guilds' own high standards and customers will know they are getting a first-class job carried out by a technician with the right skills for the task. Drain Doctor always makes certain staff are trained to the highest standards in order to give customers dazzling service. Now, with City & Guilds accreditation, Drain Doctor can offer franchisees the best possible training available to provide their staff with a nationally recognised qualification."
