Every now and then an actor appears in three very different projects in quick succession, and you start checking the name behind them. That’s the pull of Hannah Onslow, whose confirmed credits run from her film debut in Empire of Light (2022) to the 2025 drama This City Is Ours (Anthea Represents). Her public profile is thin — no official height, no fully confirmed birthplace — and the distance between verified credits and database rumor is real.

Key facts about Hannah Onslow

Nine data points, one pattern: the professional side of Onslow’s profile is documented, while the personal side stays private.

Field Detail
Full Name Hannah Onslow
Birth Date 1 April 1998 (Wikipedia)
Birthplace Not fully confirmed — the two leading listings are Havering, Greater London and Romford (see the section below)
Occupation Actress
Active Years 2021–present for confirmed listings; an earlier Call the Midwife credit is unverified (The Media Eye)
Notable Works Empire of Light (2022); Belgravia: The Next Chapter (2024); This City Is Ours (2025)
Height Not disclosed
Children None known
Social Media Instagram (private)

The table highlights the divide between Onslow’s well-documented professional milestones and her mostly private personal life.

Was Hannah Onslow in Call the Midwife?

The short answer: possibly, but the credit is thin. A 2024 rising-stars profile in The Media Eye (a UK entertainment-trade publication) says her TV debut came through Call the Midwife (The Media Eye), and third-party databases such as Plex list a 2012 episode credit for her (Plex). Independent confirmation of that early appearance is limited, which may be why the credit does not appear in every cast list.

The catch

The same third-party database that lists the 2012 Call the Midwife credit also lists Big Mood (2024) and Solers United (2025) — credits that do not appear in her agency’s profile. When one entry on a page is loose, the whole page deserves caution (Plex).

What is not in dispute is the run of confirmed credits that followed: a 2022 film debut, steady television work through 2023–2024, and a 2025 series role.

What movies has Hannah Onslow been in?

  • Ridley Road (2021) and Indiana Jones and the Dial of Destiny (2023, credited as Student) (The Media Eye)
  • Empire of Light (2022) — Janine; described as her film debut in the same profile (Anthea Represents)
  • This Is Going to Hurt (2022) — BBC One (Wikipedia)
  • The Doll Factory (2023), Belgravia: The Next Chapter (2024) — Emily Dunn — and This City Is Ours (2025) — Diana (Anthea Represents)

The range matters more than the volume: a Sam Mendes film, a blockbuster franchise, a period miniseries, and a contemporary drama. That breadth is the strongest signal in her early résumé.

Who is Diana in The City Is Ours?

Why this matters

Diana gives the career a clear next marker: a 2025 series role confirmed by her agency, not just a database echo (Anthea Represents).

In This City Is Ours (2025), Onslow plays Diana, a character listed in her agency’s casting profile as one of her later major TV roles. Public records on the character are thin beyond the casting itself, but the booking is a useful clue: period drama and film work have not locked her into one lane.

Bottom line: The pattern: the confirmed filmography runs 2021–2025 without a gap, while the Call the Midwife credit sits apart as a much earlier, less documented appearance. Verified credits, not database echoes, are the safer guide.

Where is Hannah Onslow from?

Onslow is English and was raised in Romford, a town inside the London Borough of Havering. TV Insider’s profile lists Havering, Greater London as her birthplace (TV Insider), and in a 2025 interview she told the Evening Standard she was born and raised in Romford (Evening Standard). The two details are consistent: Romford sits inside Havering.

What is Hannah Onslow’s nationality?

Nationality: British (English) · Region: Greater London · Raised in: Romford

Every profile reviewed for this article describes her as British or English, and none of the sources in the research contradicts that. The only variation is geographic detail, not nationality.

How old is Hannah Onslow?

Born: 1 April 1998 (Wikipedia) · Age now: late twenties as of 2025

That makes her 24 when Empire of Light arrived in 2022 and in her mid-twenties when Belgravia: The Next Chapter aired in 2024. Her birth date is the most consistently sourced personal detail in her profile.

What was her early life like?

  • Trained at RADA; some profiles also note BRIT School (The Media Eye)
  • The turning point: a monologue performance that convinced her to pursue acting (Evening Standard)

That combination — a London hometown, a performing-arts school, and drama-school training — is a standard route into British screen acting, but the public record stays light on specifics before 2021.

The picture: a genuinely London-rooted biography, with Havering and Romford as the anchor and RADA training as the formal bridge into the industry.

How tall is Hannah Onslow?

There is no reliably sourced height for Onslow. TV Insider’s listing, one of the fuller public profiles, does not include a height figure (TV Insider), and none of the other sources used here provides one. A specific number on a fan site is not a verified fact.

How many children did Hannah Onslow have?

  • Children: none publicly documented
  • Family status: not disclosed in any profile used here

The question appears to be a search-engine mix-up rather than a confirmed biography detail; the research contains no record of children.

Is Hannah Onslow married?

Marital status: Not publicly disclosed · Relationship details: None on record

No profile lists a spouse or partner. Her Instagram account is private, so personal updates do not surface in public roundups. The honest read: “no public record” is different from a confirmed “no.” Treating absent data as a negative is how unreliable biographies get written.

What’s confirmed, what’s still unclear

With research confidence low, the profile weights caution: three facts hold up, four areas stay open.

Editor’s note

This profile deliberately separates verified credits from database listings. Where independent confirmation is thin — the 2012 Call the Midwife credit, Big Mood, Solers United — we flag it instead of repeating it as biography.

Confirmed facts

  • An actress with agency-confirmed credits in Empire of Light (2022) and Belgravia: The Next Chapter (2024) (Anthea Represents)
  • Born 1 April 1998 (Wikipedia)
  • British and raised in Romford, London (Evening Standard)

What’s unclear

  • Birthplace details: Havering listings vs. her own Romford statement (TV Insider, Evening Standard)
  • Height: no official figure anywhere in the research
  • Marital status and children: no documentation
  • Early credits such as Big Mood (2024) and Solers United (2025) lack corroboration (Plex)

What this means: the low-confidence areas are exactly where database listings diverge. Weight the confirmed list, and read the unclear list as open, not false.

What the key sources say

Three voices carry most of what we know about Onslow: a trade profile, a newspaper interview, and her own agency.

The “Rising Stars” feature on Onslow tracked her from a film debut in Empire of Light to a major role in Belgravia: The Next Chapter in 2024 — a two-year run that gave her profile real traction.

The Media Eye, UK entertainment-trade publication

Interviewed in 2025, Onslow told the Evening Standard she was born and raised in Romford, and that performing a monologue was the turning point that led her to decide to become an actor.

Evening Standard interview with Hannah Onslow

Her casting agency profile lists the key screen credits in sequence — Empire of Light, The Doll Factory, Belgravia: The Next Chapter, and This City Is Ours — the last as the character Diana.

Anthea Represents casting profile

These three voices agree more than they conflict: the verified career is real, and the private details stay private.

The takeaway

What holds up in the public record is a young British actress with a consistent run of confirmed credits, a 1998 birth date, and a Romford upbringing; everything else — height, marriage, children, and the early database extras — is unverified or absent. The pattern is coherent: the professional résumé is documented, the private one is not. For casting directors and talent watchers, the choice is clear: track her next confirmed role — Diana in This City Is Ours — or keep trading on database listings that may never harden into facts.
