On a typical weekday morning in Britain, long before much of the country has fully woken up, Ellie Costello is already live on air—calm, composed, and guiding viewers through the day’s first wave of news. It’s a role that demands clarity under pressure, the ability to shift tone quickly, and a steady presence when events are still unfolding. For many viewers, she has become a familiar face at breakfast. But beyond the studio lights, her story is one of steady ambition, newsroom discipline, and a career shaped as much by reporting in the field as by presenting from a desk.
Ellie Costello is not a celebrity in the traditional sense. She is a working journalist who has gradually built her reputation through reporting, live broadcasting, and the ability to connect with an audience. Yet her growing visibility at GB News—and the personal experiences she has spoken about publicly—have brought increased attention to her life, her career path, and the realities of being a modern television presenter.
Early Life and Background
Ellie Costello grew up in Essex, a county in the southeast of England that has produced its share of media personalities but remains grounded in everyday British life. She has described Essex as home for most of her life, apart from her years at university, and that sense of place has shaped her early perspective on the world.
Details about her family background are limited, and she has kept much of her private life away from public discussion. There is no widely confirmed information about her parents’ professions or whether she has siblings, which reflects a conscious choice common among journalists who prefer to separate personal history from professional identity.
What is clearer is that Costello’s early years were not defined by immediate access to television or media circles. Instead, her trajectory reflects a more typical route into British journalism, one that depends on education, persistence, and entry-level newsroom experience rather than industry connections.
Education and First Ambitions
Costello studied English Literature at the University of Southampton, a choice that suggests an early interest in storytelling, language, and analysis. An English degree is a common starting point for journalists in the UK, offering a foundation in writing and critical thinking rather than technical reporting skills.
After completing her undergraduate degree, she pursued a master’s in Broadcast Journalism at City, University of London. That program is widely regarded as one of the key training grounds for British journalists, combining practical newsroom training with legal and ethical frameworks. Students are typically trained in radio, television, and digital reporting, often producing live broadcasts and working under tight deadlines.
Her decision to take that route signals a clear intention from an early stage. Broadcast journalism is not an accidental career; it requires specific training, and the competition for roles is intense. By the time she finished her postgraduate studies, Costello had positioned herself for entry into one of the country’s most demanding industries.
Starting Out at the BBC
Costello began her professional career at the BBC World Service, a global broadcasting platform known for its emphasis on accuracy, clarity, and international reach. For a young journalist, it is a challenging environment that requires quick adaptation and strong editorial judgment.
Working at the World Service often involves covering global stories for a diverse audience, which can sharpen a reporter’s ability to explain complex issues simply. It is not a place where personality dominates; the focus is on information, context, and credibility. That early experience likely shaped Costello’s measured delivery style and her approach to news as something that must be both accessible and precise.
She later moved to the Victoria Derbyshire programme, a BBC news and current affairs show known for its focus on human-interest stories and social issues. This shift marked a move from broad global reporting to more personal, UK-focused storytelling. The programme’s tone—empathetic, investigative, and often emotionally grounded—allowed her to develop a different set of skills.
Developing a Reporting Voice
At the Victoria Derbyshire programme, Costello worked on stories that required sensitivity as well as persistence. Reports connected to social media exploitation, online harassment, and personal testimony became part of her portfolio. These were not stories built around headlines alone; they depended on interviews, trust, and careful handling of vulnerable subjects.
This period of her career is important because it shaped her reporting voice. Rather than focusing solely on politics or breaking news, she developed an interest in stories that explore how events affect people’s lives. That balance—between hard news and human experience—would later define her work as both a reporter and presenter.
Recognition followed, including being identified as a “Rising Star” within BBC circles, according to her professional profiles. While such labels are often informal, they suggest that her work was noticed within the organisation, which is not easily achieved in a large newsroom.
Joining GB News
In May 2021, Costello joined GB News as a South-East reporter, becoming part of the channel’s founding team ahead of its launch. GB News entered the UK media market as a challenger broadcaster, positioning itself as an alternative to established networks such as the BBC and Sky News.
Joining a new channel carries both opportunity and risk. On one hand, it allows journalists to grow quickly as the organisation expands. On the other, it places them in a highly scrutinised environment where every editorial decision is examined. Costello’s role as a regional reporter meant she was often out in the field, covering stories across the southeast of England.
Her early assignments included live reporting from major national events and developing news stories. This stage of her career reinforced her identity as a reporter rather than just a studio presenter, a distinction that continues to shape how she approaches her work today.
Transition to National Presenter
Over time, Costello moved from field reporting into more prominent presenting roles within GB News. Her ability to handle live broadcasts, conduct interviews, and maintain composure under pressure made her a natural fit for studio work.
Her transition into breakfast television marked a significant turning point. Breakfast programmes demand a different kind of skill set, blending hard news with conversation, viewer engagement, and lighter segments. Presenters must shift quickly between topics while maintaining a consistent tone.
Costello became a regular face on GB News Breakfast, eventually taking on a five-day presenting role. She has co-hosted alongside established figures such as Eamonn Holmes and Stephen Dixon, positioning her within a team that combines experience with newer voices.
Major Assignments and On-the-Ground Reporting
Despite her move into presenting, Costello’s career has remained closely tied to reporting. She has covered several high-profile events, including the death of Queen Elizabeth II, reporting from outside Windsor Castle as the news broke.
She was also among reporters on the scene following the murder of MP Sir David Amess, a story that carried both national significance and personal proximity, given its location in the southeast. Such assignments require careful reporting, particularly in the immediate aftermath of traumatic events.
Her work has also included coverage of court cases, protests, and political developments. These experiences contribute to her credibility as a journalist, reinforcing that her role is not limited to reading headlines but includes gathering and interpreting information.
The Stalking Ordeal
One of the most difficult periods in Costello’s life became public when she revealed that she had been stalked for 16 months by a man she had never met. The situation began after a professional interaction conducted over Zoom, illustrating how even routine work can lead to unexpected risks.
The stalking escalated from online messages to physical actions, including sending unwanted items and appearing in locations connected to her work. Costello later described the experience as deeply distressing, involving anxiety, fear, and a constant sense of being watched.
The case eventually led to a conviction, with the perpetrator receiving a suspended sentence and a restraining order. Costello chose to speak publicly about the ordeal, not as a way of drawing attention to herself but to highlight the seriousness of stalking and the importance of early reporting.
Her account resonated with many people, particularly women in public-facing roles. It also underscored the risks that come with visibility in the digital age, where personal boundaries can be harder to maintain.
Personal Life and Marriage
In April 2025, Ellie Costello married Gerard Durkan in a ceremony at Chelsea Old Town Hall in London. The event attracted media attention, reflecting her growing public profile as a television presenter.
The couple had announced their engagement in late 2023, and the wedding was described in coverage as a relatively intimate but celebratory occasion attended by family and friends. Costello has not shared extensive details about her relationship, maintaining a level of privacy despite public interest.
Her approach to personal life reflects a broader pattern among journalists. While actors and entertainers often build careers around public exposure, journalists typically aim to keep their private lives separate from their professional roles. Costello has largely followed that path, sharing key milestones without turning them into ongoing public narratives.
Public Image and Media Presence
Costello’s public image is shaped by her role as a broadcaster rather than a celebrity personality. She is known for a composed on-screen presence, clear delivery, and the ability to handle live interviews with confidence.
Her association with GB News places her within a specific segment of the British media landscape. The channel has attracted both loyal viewers and criticism, and its presenters often find themselves part of broader debates about journalism and broadcasting standards.
That said, Costello’s individual reputation is built more on her professionalism than on controversy. She is not known for outspoken political commentary or polarising statements. Instead, her approach tends to focus on facilitating discussion and presenting information.
Income, Career Stability, and Net Worth
There is no publicly verified figure for Ellie Costello’s salary or net worth. Estimates sometimes appear online, but they are rarely supported by reliable financial disclosures or confirmed reports.
As a television presenter at a national news channel, her income is likely to reflect industry standards for mid- to high-level broadcasters in the UK. These figures can vary widely depending on experience, role, and contract terms.
It is important to approach such estimates with caution. Without confirmed data, any specific number should be treated as speculative rather than factual. What can be said with confidence is that her career has reached a level of stability that places her among established broadcast journalists.
Where Ellie Costello Is Now
As of 2026, Ellie Costello continues to work as a key presenter on GB News Breakfast, appearing regularly on weekday mornings. Her role involves not only presenting but also engaging with live interviews, breaking news, and audience interaction.
She remains active in covering major events and contributing to the channel’s broader output. Her career appears to be on an upward trajectory, with increasing responsibility and visibility.
What’s interesting is that her path reflects a broader shift in journalism. Modern presenters are expected to be versatile, moving between reporting, presenting, and digital engagement. Costello’s career fits that model closely.
