In 1993, Kielty presented the show "SUS" on UTV. He later became the warm-up act for a BBC Northern Ireland programme, "Anderson on the Box", presented by local personality Gerry Anderson. When this show was axed, he presented its replacement, "PK Tonight". Although this ran for only a year and was only shown in Northern Ireland, it did attract the attention of London-based broadcasters, winning him the "Best Newcomer" Award at the 1996 Royal Television Society Awards. In 1997, he set up the Belfast-based TV production company Green Inc with TV director Stephen Stewart, making shows such as "The Afternoon Show", "Patrick Kielty Almost Live", and "Ask Rhod Gilbert". It was reported in 2010 that Kielty had sold his share in the company. Kielty graduated to presenting programmes such as "Last Chance Lottery" and "Patrick Kielty Almost Live", broadcast throughout the UK. Former football star George Best later gave his first TV interview following his liver transplant to Kielty on the same show.
