Leaving the remote farm: “Clarkson’s Farm” star Harriet Cowan surprises with her appearance at a £4 million mansion.

Harriet Cowan’s rise from temporary farmhand on Clarkson’s Farm to one of the show’s most talked-about new faces has taken another step, as she helps promote a major Cotswolds house draw worth £4 million.

The Derbyshire farmer joined the latest season of the Prime Video series after stepping in for Kaleb Cooper while he was away on tour. Although her time on screen was relatively short, Cowan quickly became popular with viewers for her practical approach, confidence around livestock, and willingness to challenge Jeremy Clarkson when farm life demanded it.

Now, the 24-year-old is back in the Cotswolds spotlight through Omaze’s latest Million Pound House Draw, which is raising funds for The Royal Marsden Cancer Charity. The prize is a refurbished country house near Cirencester, complete with a four-bedroom main home, a separate two-bedroom cottage, landscaped gardens, countryside views and a significant cash prize for the eventual winner.

The property, valued at £4 million, is being offered mortgage-free, with stamp duty and legal fees covered. The winner will also receive £250,000 in cash, as well as £175,000 worth of furnishings. That means the prize is not only about owning a luxury rural home, but also about having the financial support to settle into it, maintain it, or use it as an income-generating asset.

For Cowan, the draw represents a return to the part of Britain where she became familiar to Clarkson’s Farm viewers. Her appearance in the Cotswolds campaign links neatly with her public image as a young farmer who understands the appeal of rural life, but also knows that countryside living involves more than picture-perfect views.

The house itself is described as a quintessential Cotswolds property. Originally built in the early 1900s, it has been carefully refurbished and extended in recent years. The result is a blend of period character and modern comfort, with original features preserved alongside brighter, more practical living spaces. Set within around an acre of landscaped gardens, the home is positioned to appeal to those who dream of a slower, more scenic country lifestyle.

The separate guest cottage adds another layer of flexibility. It could be used for family and friends, longer stays, or potentially as part of a rental arrangement. Local estate agents estimate that, if rented out long-term, the full property could achieve between £12,500 and £15,000 per month. That makes the prize valuable not only as a home, but as a possible source of substantial income.

Omaze has built its UK profile by offering high-value properties while raising money for charitable causes. The company says its community has raised more than £100 million for UK charities. This latest draw is supporting The Royal Marsden Cancer Charity, which funds work linked to cancer treatment, research, diagnosis and care.

Cowan’s involvement gives the campaign a familiar face for viewers who followed the latest season of Clarkson’s Farm. She appeared during a period of change on Diddly Squat Farm, temporarily filling a gap left by Kaleb Cooper. Her role was never presented as a permanent replacement, but her presence added a fresh dynamic to the series. She brought youth, practical skill and a calm sense of competence to a farm already known for chaos, humour and difficult decisions.

Her departure midway through the season came once her help was no longer required, but the impression she made lasted beyond her screen time. Fans responded to her straightforward personality and her ability to hold her own alongside Clarkson. In a series where newcomers can easily be overshadowed by established figures, Cowan managed to stand out without forcing the moment.

That popularity helps explain why she is a natural fit for a campaign built around the Cotswolds lifestyle. Clarkson’s Farm has made the region feel familiar to a global audience, presenting it as beautiful, demanding and often unpredictable. A £4 million country house in the same wider landscape taps directly into that fascination.

However, the draw is also about aspiration. For many viewers, owning a Cotswolds period home is far beyond reach. The Omaze model turns that fantasy into a chance-based opportunity, while connecting the entry process to a charitable cause. The inclusion of cash, furnishings and covered fees is especially important, because luxury homes can bring significant running costs. Without those extras, a prize of this scale could become difficult for an ordinary winner to manage.

The winner will have several choices. They can live in the house, rent it out, or sell it and become a cash multi-millionaire. That flexibility makes the prize more practical than it may first appear. It is not simply a dream home; it is a financial turning point.

For Cowan, the campaign also shows how quickly Clarkson’s Farm can change a person’s public profile. A brief role on the show has opened doors beyond the farm gate, connecting her to national promotions and a broader audience. Yet her appeal still rests on the same qualities that made viewers notice her: authenticity, rural credibility and an easy connection to countryside life.

The draw closes at midnight on Sunday, March 29. One entrant is guaranteed to win the property, making the campaign one of Omaze’s most eye-catching Cotswolds offerings to date.

For Clarkson’s Farm fans, Cowan’s involvement adds another point of interest. She may have left Diddly Squat after her temporary role ended, but her link with the Cotswolds has clearly continued. And with a £4 million house, a major charity partnership and a growing public profile, Harriet Cowan’s post-Clarkson’s Farm journey appears to be only just beginning.
