The dating show, which features single people with disabilities, will return with a new four-part series next year, The Sun reports.
The programme attracted ratings of up to three million during its first run, making it one of Channel 4's most successful shows of the year so far.
However, The Undateables's promotional campaign has been criticised and branded offensive towards disabled people.
The Advertising Standards Authority received 21 complaints claiming that the adverts may encourage stereotyping and bullying.
Channel 4 was later cleared of any wrongdoing or breaching the advertising code.
The Undateables is made by production company Betty, which also produces The Joy of Teen Sex.
