About
Christian Cox
In the heart of Ascot lives Christian Cox, a man defined by lists, discipline, and a 6:30 a.m. start. Far from your average estate agent, Cox is an author, property developer, and relentless force of energy. His debut novel Agency is a vibrant, fictionalised account of the estate agency world in early-2000s London—a time Cox calls “the Halcyon days” of property, ambition, and opportunity.
Cox’s disciplined lifestyle sets the tone for everything he does. From preparing five bespoke hot drinks for his family each morning to building and selling over 130 apartments across London, his philosophy is simple: do it properly, or don’t do it at all.
That mindset defined his years as an ambitious young estate agent in the capital. Arriving in London in 1999 with barely enough for a month’s rent—and not even the deposit—Cox began his journey with little more than grit. A sympathetic landlord gave him a chance, and soon Cox was climbing the ranks of one of London’s most competitive estate agencies.
By his early thirties, he had crossed over into property development, leaving his mark on some of London’s most desirable postcodes. But one story had always been waiting to be told: the inside tale of life in estate agency at the height of London’s property boom.
“So many people said, ‘Someone has to write a book about estate agency in the noughties,’” Cox recalls. “The characters, the ambition, the absurdity—it was crying out to be told.”
That idea became Agency, his debut novel. The book follows “Agent C,” a sharp-suited, determined twenty-something navigating the chaos and comedy of property sales in London’s high-octane early 2000s. Though fictional, the novel captures the real spirit of the industry during a golden age of money, ambition, and hustle.
While Agency is not a memoir, Cox describes it as “emotionally autobiographical.” Many of the characters, stories, and lessons are drawn directly from his experiences on the frontlines of property sales.
The book is more than entertainment—it doubles as a masterclass in sales. One chapter outlines Cox’s tried-and-tested sales process, refined over decades. Readers have found it surprisingly transferable. “I’ve had friends say, ‘I used your sales levels at the car dealership,’” Cox laughs.
Each chapter is also paired with its own soundtrack, celebrating 80s, 90s, and early 2000s soft rock. “If you don’t like that music, don’t buy this book,” he jokes. “But if you do, you’re in for a ride.”
The decision to finally write the book came after the loss of a close friend, who had asked Cox a simple but life-changing question: “What are you going to do differently?”
That challenge inspired him to commit to three goals: write the book, learn a language, and work less. Agency became a tribute to his friend, a celebration of ambition, and a reminder of the lessons he learned in one of Britain’s most fast-paced industries.
In true Cox fashion, he wrote the entire manuscript in just 100 days, supported by the PublishU coaching program. “There’s something in the structure Matt’s built—it’s alchemy,” he says. “It helped me do something I never thought possible.”
For Cox, Agency is not about self-promotion. All profits go to the MND Association and CLIC Sargent, causes close to his heart. “This isn’t about me,” he explains. “It’s about doing something good. But I am proud. Hugely. Every day, my wife still says, ‘I can’t believe you wrote a book—and people are buying it.’”
Beneath the glamour of London property is a man who values honesty, consistency, and humanity. “People don’t buy the house first. They buy the agent. And you can’t fake that,” Cox says.
It’s a lesson that runs through both the novel and his own career: success comes from authenticity, not pretense. From the days of wearing a grey three-piece suit that drew teasing from colleagues, to becoming a confident disruptor in the property market, Cox has always stayed true to himself.
Cox hopes Agency will both entertain and challenge perceptions of estate agents. “People love to hate estate agents, but they don’t see the passion, the pressure, the camaraderie,” he says. “If people read this and laugh, or see that side for the first time, that’s a win.”
For anyone thinking about writing, Cox’s advice is simple: “Write it. Don’t overthink it. If I can do it, anyone can.”
His journey proves that with discipline, structure, and determination, even the busiest professionals can find time to tell their stories.
With Agency, Christian Cox delivers more than just a story about property. He offers readers an insider’s glimpse into the ambition and absurdity of estate agency during London’s property boom. It’s a novel full of energy, music, and humour—but also valuable life lessons on sales, authenticity, and resilience.
Cox’s journey from estate agent to author is proof that stories worth telling come from everyday experiences, lived with passion and honesty. Agency is a tribute to a remarkable era in British business, and a reminder that success, whether in sales or storytelling, is about staying true to who you are.
