Here are the key biographical facts about Sally Thomsett.

Did Richard O’Sullivan Date Sally Thomsett?

The short answer is yes. In her public tribute following O’Sullivan’s death in 2025, Thomsett referred to him as her former partner, confirming the off-screen romance many fans had suspected.

According to The Times (UK obituaries), O’Sullivan began a relationship with Thomsett during the run of Man About the House. The relationship continued after the show ended and was described by those close to the pair as significant.

What did Sally Thomsett say about their partnership?

• In a Facebook post shared by the British Comedy Classics page, Thomsett reportedly said they “had a wonderful time together” and that O’Sullivan was “a kind and funny man.” (Mirror (UK showbiz))

How did the relationship affect their on-screen chemistry?

The show’s premise — a man sharing a London flat with two single women — benefited from the natural rapport between O’Sullivan and Thomsett. The Guardian (UK national newspaper) noted that the cast’s genuine friendships made the comedy feel effortless.

The implication: the on-screen chemistry was rooted in a real, off-screen bond that outlasted the series.

Who Was the Love of Sally Thomsett’s Life?

Sally Thomsett never married, and publicly available records show no other long-term partner besides Richard O’Sullivan. While fans have speculated about her private life, the only confirmed romantic chapter is the one she shared with O’Sullivan.

According to Wikipedia, Thomsett’s biographical pages do not list a spouse or children. She has largely kept her personal life out of the tabloids since the 1980s.

What this means: O’Sullivan remains the only confirmed significant partner, but the exact timeline of their relationship is not publicly detailed.

Is Sally Thomsett Older Than Jenny Agutter?

Yes — by two years. Sally Thomsett was born on 3 April 1950, while Jenny Agutter was born on 20 December 1952 (Wikipedia, Wikipedia). Both actresses played sisters in The Railway Children (1970), with Agutter playing the older sibling Roberta and Thomsett playing the younger Phyllis — an age-appropriate casting choice that worked naturally.

Their age difference never affected their on-screen dynamic, and both went on to have notable careers. Agutter remains active in film and television, while Thomsett’s career was largely concentrated in the 1970s.

When Did Sally Thomsett Leave Man About the House?

Thomsett played Jo for six series from 1973 until 1976, appearing in all 39 episodes (IMDb full credits). She left the show before it ended, and did not reprise her role in the spin-off series George and Mildred or Robin’s Nest.

The exact reason for her departure was not widely reported, but the show’s creators, Brian Cooke and Johnnie Mortimer, moved the narrative toward the characters of George and Mildred Roper, played by Yootha Joyce and Brian Murphy.

The Guardian (UK national newspaper) notes that the programme ran for six series and attracted audiences of up to 16 million at its peak.

The pattern: her departure aligned with the show shifting focus to the Ropers, a common TV spin-off strategy.

Are Any of the Cast of Man About the House Still Alive?

As of 2025, Sally Thomsett is still alive. Richard O’Sullivan died in 2025 at the age of 76 (The Guardian). Paula Wilcox (Chrissy) is also alive and continues to act. Yootha Joyce passed away in 1980, and Brian Murphy died in 2024.

The current status of other cast members, such as the actors who played minor roles, is less publicly documented.

What Happened to Richard O’Sullivan from Man About the House?

Richard O’Sullivan suffered a major stroke in 2003 (The Times (UK obituaries)). The stroke left him needing full-time care, and he spent the rest of his life in a care home. He died in 2025.

What illness did Richard O’Sullivan have?

Beyond the stroke, no specific long-term illness has been confirmed in major news outlets. The stroke itself was the pivotal health event that changed his life.

Why was Richard O’Sullivan in a care home?

According to The Times, the stroke caused significant disability, making independent living impossible. His family arranged residential care, which he received until his death.
