Introduction
Jayne Sinfield is best known as the wife of Kevin Sinfield — one of Britain’s most decorated rugby figures — but her story extends well beyond that association. A professional hair stylist with her own salon in Leeds and a registered Company Secretary, she has built a life defined by independence, family stability, and quiet influence.
While Kevin’s achievements in sport, coaching, and charity dominate headlines, Jayne’s role has been central behind the scenes — providing the foundation that makes sustained success possible. Her ability to remain grounded in a highly public environment sets her apart as a genuinely distinctive figure in British public life.

Early Life & Background
Yorkshire Roots and Upbringing
Jayne Sinfield is closely associated with Yorkshire, particularly Leeds — a connection that has remained constant throughout her life. Unlike many individuals linked to high-profile sports figures, she has never sought relocation or celebrity exposure, choosing instead to stay rooted in the community she grew up in.
That regional loyalty speaks to something deeper than geography. The values that shape her approach to family and work — practicality, discretion, community — are very much Yorkshire values.
Education
She studied at Leeds Metropolitan University (now Leeds Beckett University), pursuing a practical, career-focused path rather than one oriented toward public life. That grounding in professional development would later define how she built her reputation in the beauty industry.
Career Journey
Hair Styling Profession
Jayne has worked as a professional hair stylist for much of her adult life — a career she established on her own terms, independent of her husband’s growing fame. Maintaining a distinct professional identity throughout a high-profile marriage is itself a quiet form of resilience.
Oasis Hair Leeds
She is associated with Oasis Hair Leeds, where she built a reputation within the local beauty industry. The salon has become known for its welcoming atmosphere and quality of service — qualities that reflect her character rather than celebrity adjacency. Regular clients value the personal touch she brings, and her ability to stay current in her craft while managing broader responsibilities.
Business Role: SINF13LD LIMITED
Beyond the salon, Jayne holds a formal corporate role as Company Secretary of SINF13LD LIMITED — the company connected to her husband’s professional activities. This position reflects involvement in operational and business administration at a meaningful level, not simply a nominal title. It adds significant depth to a profile that might otherwise be reduced to a supporting role.
The combination of salon ownership and corporate responsibility positions Jayne as a genuinely dual-track professional — something rarely acknowledged in coverage of celebrity spouses.
Major Works / Achievements
Professional Contributions
Her continued work in the beauty industry reflects long-term dedication rather than short-term visibility. Running a salon while managing family responsibilities and a corporate role is a significant undertaking — one that rarely gets the attention it deserves.
Support in MND Charity Campaigns
Jayne has played a crucial role in supporting Kevin’s high-profile fundraising efforts for motor neurone disease (MND) — campaigns that have raised over £11 million to date and brought national attention to the cause. These endurance challenges demand enormous logistical and emotional support from the people closest to Kevin.
Her contribution matters because it enables sustainability. Without a stable home base, the kind of extreme fundraising Kevin undertook — including seven marathons in seven days and multiple multi-day ultra challenges — would be far harder to sustain. Behind every public mile was a private infrastructure Jayne helped maintain.
Public Appearances
She has appeared at key national events, including honours ceremonies and charity milestones. These moments are rare, which is precisely what makes them meaningful — her presence signals genuine personal investment rather than managed appearances.
Net Worth
Financial Overview
Jayne Sinfield’s individual net worth is not publicly disclosed. Financially, the household is supported by a strong dual-income structure: Jayne’s salon business and corporate role sit alongside Kevin’s career in professional rugby, coaching, and charity work. Kevin’s estimated net worth is reported at around $5 million, accumulated across a career that included multiple Super League titles, a CBE, and high-profile coaching appointments.
The absence of public financial data reflects Jayne’s preference for privacy — not a lack of professional contribution.
Personal Life
Marriage to Kevin Sinfield
Jayne met Kevin during a night out in Oldham, when Kevin was in his early twenties and still in the early stages of his Leeds Rhinos career. The fact that their relationship began well before fame arrived is something both of them have referenced — it means the foundation was built on something real, not on celebrity or status.
Relationship Timeline
- Met during Kevin’s early career, at a night out in Oldham
- Relationship developed before public recognition arrived
- Married in 2006
- Partnership continued through career transitions, coaching appointments, and major charity campaigns
Children and Family Life
The couple has two sons:
- Jack Sinfield (born 2004) — professional rugby league player; signed his first professional contract with Leeds Rhinos in 2021 at age 16, made his first-team debut in 2022, and in late 2025 joined Wakefield Trinity on a three-year deal
- Sam Sinfield (born 2006)
Both boys grew up around rugby, though the family has consistently shielded them from excessive media attention. Their approach to parenting prioritises normalcy — an intentional choice that says a good deal about Jayne’s values.
Role in Kevin Sinfield’s Career & Charity Work
Behind-the-Scenes Support
Jayne’s role goes well beyond emotional support. During Kevin’s physically demanding charity challenges — often spanning multiple days and requiring intense preparation — she manages family life and stability at home, allowing him to remain focused entirely on performance and fundraising targets.
Kevin has spoken openly about the importance of that support. It’s not incidental to his achievements; it’s part of what makes them possible.
Impact on MND Campaigns
Kevin Sinfield’s MND fundraising — begun in late 2020 in honour of his former Leeds Rhinos teammate Rob Burrow, who passed away in June 2024 at the age of 41 — has grown into one of British sport’s most significant charitable legacies. The campaigns have raised over £11 million, with Kevin widely tipped for a knighthood in recognition of the contribution.
Through each campaign, Jayne’s consistent presence behind the scenes transformed what could have been a personal gesture into a sustained, multi-year movement. That continuity doesn’t happen without the stability she provides.
Latest Updates / Current Status
Current Lifestyle

Kevin is currently serving as skills and kicking coach for the England national rugby union team — a role he took on in December 2022 following Steve Borthwick’s appointment as head coach.
Recent Public Presence
She occasionally appears at events connected to Kevin’s career and charity work but avoids regular media exposure. That consistency — showing up when it matters, staying out of the frame otherwise — is very much her approach.
