Lenny Rush is one of the most recognisable young actors in British television. He first appeared on screen as a child and quickly built a reputation for comic timing, natural performances and a confidence that belies his age.
He became widely known as Ollie in the BBC comedy thriller Am I Being Unreasonable?, starring alongside Daisy May Cooper. The performance earned him a BAFTA Television Award in 2023, making him one of the youngest performers to win major recognition in the category. The BBC has also highlighted his BAFTA-winning performance as one of the programme’s major successes.
Since then, Rush has appeared in Dodger, Doctor Who, Enola Holmes 2, Renegade Nell and other productions. In 2026, his profile has risen again through roles in A Woman of Substance and Slow Horses, while HBO has announced him as the actor playing Dobby in the second season of its new Harry Potter television series.
Lenny Rush age: How old is he?
Lenny Rush is 17 years old as of September 2026.
He was born in March 2009 in Essex, England. Several entertainment databases list 18 March, while other biographical sources, including the current English-language Wikipedia entry and IMDb’s biography information, list 17 March 2009. Because publicly available databases conflict, it is sensible to treat the exact day cautiously rather than present an uncertain date as definitive.
Rush began working professionally while still a child and has continued to combine acting with his education and family life.
Who are Lenny Rush’s parents?
Lenny Rush’s parents are Lisa and Steve Rush. His family has played an important role in his early career.
His mother, Lisa, previously worked as a dental nurse and gave up her job after Lenny was born to care for him. His father, Steve, runs a kitchen design business. Rush has spoken warmly about the support he has received from both parents.
The family lives in Essex, and Lenny has a younger brother named Bobby. In interviews, his family dynamic has come across as supportive and grounded rather than focused on celebrity.
That support was particularly important as Rush began working professionally at a young age.
Lenny Rush’s brother Bobby
Lenny’s younger brother is Bobby Rush.
Bobby has generally remained away from the entertainment spotlight. Lenny’s mother has spoken about the brothers’ relationship and described Bobby as taller than his older brother. The family has also discussed how they have maintained an ordinary home life despite Lenny’s growing public profile.
There is relatively little reliable public information about Bobby, so claims about his age, personal life or career should be treated carefully.
What condition does Lenny Rush have?
Lenny Rush has spondyloepiphyseal dysplasia congenita (SEDC), a rare genetic skeletal condition that affects bone and physical development.
The condition affects his growth and is the reason he has dwarfism. Rush has spoken openly about his experiences and has made it clear that he does not want his condition to define his career.
In a 2023 interview with The Guardian, he discussed the physical challenges associated with SEDC, including effects on mobility, stamina, balance, hearing and sight. He also spoke about surgeries he has undergone, including spinal surgery.
His openness has made him an important figure in discussions around disability representation on British television. More importantly, his acting career demonstrates that disability does not prevent a performer from taking on complex, prominent roles.
Lenny Rush height
There is no reliably verified official figure for Lenny Rush’s height that should be treated as definitive.
Various websites publish measurements for Rush, but these figures are inconsistent and are not supported by a strong primary source. His short stature is connected to his SEDC, but giving a precise height without reliable verification would risk turning an estimate into a supposed fact.
For that reason, it is better to describe Rush as a performer with dwarfism rather than attach an unsupported numerical measurement to his biography.
Lenny Rush’s acting career
Rush’s career began remarkably early.
He first appeared on television in the CBeebies documentary series Our Family. According to The Guardian, he was seven when his mother applied for the programme, and the experience helped him discover that he enjoyed performing in front of a camera. He subsequently attended the Pauline Quirke Academy of Performing Arts in Essex.
His early credits included:
- Apple Tree House
- The Dumping Ground
- A Christmas Carol
- Dodger
- Am I Being Unreasonable?
- Enola Holmes 2
- Best Interests
- Doctor Who
- Renegade Nell
- A Woman of Substance
- Slow Horses
He has also taken on presenting and entertainment appearances, including work connected with Children in Need.
Lenny Rush in Am I Being Unreasonable?
For many viewers, Am I Being Unreasonable? remains the role that established Lenny Rush as a major young British acting talent.
Rush plays Ollie, the son of Daisy May Cooper’s character, Nic. The BBC describes Ollie as the young son at the centre of Nic’s complicated family life.
Ollie is more than a conventional sitcom child character. His relationship with his mother is an important part of the show’s emotional and comic structure. Rush’s performance combines humour with moments of surprising maturity.
He also spoke about the character before the programme premiered, describing Ollie as complicated and suggesting that the relationship between Ollie and his mother sometimes works almost in reverse, with Ollie acting as the more mature figure.
Lenny Rush BAFTA win
Rush won the 2023 BAFTA Television Award for Male Performance in a Comedy Programme for his role as Ollie in Am I Being Unreasonable?.
The win was a major breakthrough. The BBC’s annual report specifically noted Rush’s victory alongside the programme’s other BAFTA recognition.
He later received further recognition at the Royal Television Society Programme Awards, winning both Breakthrough Award and Comedy Performance (Male) in 2023.
Lenny Rush BAFTA 2026
Rush was nominated again at the 2026 BAFTA Television Awards, this time in the Actor in a Comedy category for Am I Being Unreasonable?.
He did not win the category in 2026. BAFTA lists Steve Coogan as the winner for How Are You? It’s Alan (Partridge), with Rush among the nominees.
That second nomination nevertheless underlines how highly his performance has been regarded.
Lenny Rush in Dodger
Rush played Morgan, also known as the Crossing Sweeper, in the BBC/CBBC series Dodger.
The series reimagines characters and stories associated with Charles Dickens’ Oliver Twist. Rush became part of the regular ensemble alongside actors including Christopher Eccleston.
The role helped broaden his television work beyond the comedy-thriller format of Am I Being Unreasonable? and demonstrated his ability to work within period drama and family television.
Lenny Rush in Doctor Who
In 2024, Rush appeared in Doctor Who as Morris Gibbons.
He appeared in the two-part story involving “The Legend of Ruby Sunday” and “Empire of Death”. The role gave him the opportunity to join one of Britain’s most recognisable television franchises.
Lenny Rush and A Woman of Substance
Rush also appeared in the 2026 television adaptation of A Woman of Substance, playing Frank Harte.
His role is listed across multiple episodes, adding another significant television credit to his growing filmography.
The project is another example of Rush moving beyond the child-comedy roles that initially made him famous.
Lenny Rush in Slow Horses
One of Rush’s newest projects is Slow Horses.
In the sixth season, he plays Reece Nesmith, joining the established cast led by Gary Oldman. Season 6 is scheduled to premiere on Apple TV on 16 September 2026, with Rush among the notable new additions.
His casting is particularly notable because Slow Horses has an established ensemble of experienced performers. Recent coverage has highlighted Rush’s ability to hold his own alongside actors such as Oldman.
For audiences searching for Lenny Rush in Slow Horses, this is one of his most important current projects.
Is Lenny Rush playing Dobby in Harry Potter?
Yes. Lenny Rush has been cast as Dobby in HBO’s new Harry Potter television series.
The casting was announced in September 2026, with Rush set to portray the beloved house-elf in Season 2. Bonnie Hill has been cast as Ginny Weasley, while Billy Barratt will play young Tom Riddle.
This is one of the biggest roles of Rush’s career so far.
Dobby was previously brought to life in the Harry Potter films through CGI and the voice performance of Toby Jones. The HBO adaptation is rebuilding the story for television, with new actors taking on the familiar characters.
Rush’s casting has attracted considerable attention because Dobby is one of the franchise’s most recognisable supporting characters.

Lenny Rush’s A Christmas Carol role
One of Rush’s earliest significant acting roles was Tiny Tim in A Christmas Carol.
He performed the role at London’s Old Vic before appearing in the 2019 television adaptation of the Charles Dickens story. His early theatre work was an important step in developing the performance skills that later became visible in his television roles.
Lenny Rush net worth
There is no reliable publicly verified figure for Lenny Rush’s net worth.
Celebrity websites sometimes publish estimates running into hundreds of thousands or millions of pounds, but these figures are generally not accompanied by audited financial information, verified contracts or credible statements from Rush or his representatives.
Because Rush is still a young actor and his earnings from individual productions are private, a precise net-worth figure would be speculation.
His growing list of television credits, awards and major projects suggests a successful career, but success should not be confused with a publicly knowable personal fortune.
Who is Lenny Rush’s agent?
Lenny Rush has been represented by Curtis Brown, a major UK talent agency. Industry listings identify agents including Alastair Lindsey-Renton, Helen Clarkson, Adam Maskell and Emma Bennett in connection with his representation.
For professional enquiries, representation should be contacted through the agency rather than attempting to obtain Rush’s private contact information.
Lenny Rush’s awards and nominations
Rush has already built an impressive awards record for a performer who is only 17.
His notable achievements include:
- 2023 BAFTA Television Award – Male Performance in a Comedy Programme, Am I Being Unreasonable?
- 2023 Royal Television Society Award – Comedy Performance (Male)
- 2023 Royal Television Society Award – Breakthrough Award
- 2023 National Comedy Awards – Breakthrough recognition
- 2026 BAFTA Television nomination – Actor in a Comedy, Am I Being Unreasonable?
- 2026 Edinburgh TV Festival Awards nomination – Best TV Actor – Comedy for Finding Father Christmas
His BAFTA win remains the standout achievement, but the continued nominations show that his early success was not a one-off.
What makes Lenny Rush stand out?
Rush’s appeal comes from more than the novelty of being a young award-winning actor.
He has strong comic timing, but he can also handle emotionally demanding material. His performance as Ollie demonstrated that he could work naturally opposite an established performer such as Daisy May Cooper, while his later roles have allowed him to explore very different genres.
He has also spoken openly about his disability without allowing it to become the sole story around his career. His attitude towards acting and his willingness to take on varied roles have helped establish him as a performer first.
That distinction matters. Representation is valuable, but Rush’s work has earned attention because audiences and critics respond to his performances.
