Who Is Jayne Sinfield?
Jayne Elizabeth Sinfield is a British professional whose public profile is mainly connected with hair styling, business administration and the Sinfield family.
She became widely recognised through her marriage to Sir Kevin Sinfield, one of the most successful and respected figures in British rugby.
Unlike her husband, Jayne has not developed a public career through television, interviews, sport or regular media appearances.
Most confirmed information about her comes from official company records, selected public profiles and documented appearances with her husband.
Her biography is therefore best understood through verified professional, business and family details rather than unsupported descriptions of her personality or private lifestyle.
Early Life and Education
Jayne Sinfield was born in January 1980 and is British. Public company records list England as her country of residence.
Regional reporting has connected her early life with Leeds, the West Yorkshire city that later became closely linked with her family and professional life.
Her publicly listed educational background includes Leeds Metropolitan University, which became Leeds Beckett University in 2014.
Her exact qualification, course of study and graduation year have not been reliably documented, so they are not included here.
Her later professional path placed her within the hair and personal-care sector, where practical skill, communication and client service are important parts of daily work.
Professional Career in Hair Styling
A public profile under Jayne’s name identifies her as a hair stylist associated with Oasis Hair Leeds.
This professional connection gives her a working identity outside the sporting achievements and public reputation of her husband.
Hair styling involves technical training, attention to detail and the ability to understand the different needs of individual clients.
Jayne has not used her professional work to build a celebrity brand or a regular public-media presence.
Claims that she owns the salon, manages a large team or operates additional beauty businesses are not included because reliable evidence does not clearly confirm them.
Company Secretary Role
Official Companies House records list her complete registered name as Jayne Elizabeth Sinfield.
She has served as the active secretary of SINF13LD LIMITED since 24 May 2016.
The company is active and is also connected with Kevin Sinfield, who is listed in its public corporate records.
Jayne is recorded as a person with significant control, with ownership of more than 25% but no more than 50% of the shares and voting rights.
These public records confirm a formal business position, although they do not describe the exact duties she performs from day to day.
Why Jayne Sinfield Is Famous
Jayne Sinfield is mainly famous because she is married to Sir Kevin Sinfield, the former Leeds Rhinos captain and England rugby figure.
Kevin spent his full senior rugby league playing career with Leeds and became known for leadership, kicking ability and major team success.
After ending his playing career, he moved into sporting leadership and rugby union coaching while remaining closely connected with the rugby community.
His endurance challenges for motor neurone disease charities brought his work to an audience far beyond professional sport.
Jayne has appeared with him at selected official events, but she has generally remained outside the main media attention surrounding his career.
Marriage to Sir Kevin Sinfield
Jayne is married to Sir Kevin Sinfield, who represented Leeds Rhinos, England and Great Britain during his rugby league career.
The couple’s relationship has been mentioned in reliable sporting and regional coverage, although they do not regularly discuss their private marriage publicly.
Kevin was appointed MBE for his rugby career, later received an OBE and was awarded a CBE for his work connected with rugby and the MND community.
In June 2026, he was selected for a knighthood for services to rugby league, rugby union and the motor neurone disease community.
Jayne attended his OBE investiture at Windsor Castle, where the Rugby Football League officially identified her as his wife.
Jayne and Kevin Sinfield’s Children
Jayne and Kevin Sinfield have two sons named Jack Sinfield and Sam Sinfield.
Jack followed his father into professional rugby league after developing through the Leeds Rhinos youth and academy system.
He made his senior Leeds debut in 2022 and later joined Wakefield Trinity ahead of the 2026 Super League season.
Jack plays as a half-back and received squad number 20 after completing his move to Wakefield.
Sam has remained outside regular professional sports coverage, so this biography does not include unsupported claims about his education, profession or future plans.
Public Appearances
Jayne does not make regular public appearances, but she has joined Kevin at selected formal and sporting occasions.
Her appearance at Kevin’s OBE investiture in January 2022 is one of the clearest officially documented examples.
The ceremony took place at Windsor Castle, where Kevin received the honour for services to rugby league and charity fundraising.
Jayne was photographed beside him with the medal following the official presentation.
Her documented appearances are usually connected with important family or career moments rather than independent celebrity events.

Jayne Sinfield’s Connection With the Rugby World
The Sinfield family has a deep connection with rugby league, the sport in which Kevin and Jack developed their professional careers. Modern players such as Tom Amone continue to represent the physical demands of the game.
Kevin played during an important period for the Super League and helped Leeds Rhinos win several major honours. The modern competition also features creative attacking players such as Bevan French.
His later work in rugby union connected the family with another major part of British sporting life. International forwards such as Malcolm Marx show the strength and technical quality found at the highest level.
Kevin’s MND fundraising has also linked rugby with health awareness and charitable action. Former England captain Lewis Moody is another well-known rugby figure whose public story includes both sport and the MND community.
Kevin has worked within the England rugby union environment alongside leading international players. Fly-half George Ford is one of the established names connected with the modern England team.
Business Interests and Public Records
Jayne’s strongest independently verified professional information comes from official UK company records.
Her position as company secretary has remained active since 2016, showing a long-term formal connection with SINF13LD LIMITED.
She was registered as a person with significant control from January 2018.
The record confirms that she holds both share ownership and voting rights within the published ownership range.
No reliable public evidence confirms additional companies, investment portfolios, product lines or separate large business ventures under her name.
Public Image
Jayne is not a television personality, professional speaker, influencer or regular interview subject.
Her public recognition mainly comes from her family connection, company role and selected appearances with Kevin.
She is often described online through personal opinions about her influence or character, but such descriptions cannot be verified as factual biography.
A reliable profile should therefore focus on her documented career, business appointment and family information.
This approach creates a clearer and more accurate account than repeating assumptions about her private beliefs, routines or role within the household.
Current Status in 2026
As of June 2026, Jayne remains recorded as the active secretary of SINF13LD LIMITED.
She also remains listed as an active person with significant control in the company’s public records.
Her professional background continues to be associated publicly with hair styling in Leeds.
Her husband received one of the most important recognitions of his public life when his knighthood was announced in June 2026.
Their son Jack is playing professional rugby league for Wakefield Trinity during the 2026 Super League season.
