Meet the team

John Horton


Owner and Director, John has lived, worked and raised his family in Hammersmith for over 20 years. His wealth of contacts and property experience across Hammersmith, Shepherds Bush, Chiswick and West Kensington is the stuff of legend. Years in corporate agency crystallised for John the importance of staff retention, dedication to continual training and industry qualification. Above all, it cemented a client-focused approach to business. Number one for sales agreed across Hammersmith, Shepherds Bush and Chiswick and number one for lettings in Hammersmith and Shepherds Bush, Horton and Garton is now one of the most successful independent businesses in West London. While working tirelessly for his clients, John’s devotion to the local community has never wavered. Horton and Garton supports a variety of charities, community groups and local events every year. His years of experience and wholehearted devotion to client satisfaction have earned John an impeccable reputation and many awards.

Paul Cooney

Director, Chiswick Sales

Horton and Garton’s Chiswick office opened in April 2017 and was born over a riverside pint. Realising they share the same principles of honesty, integrity and professionalism, Paul and John decided it was the perfect partnership.

Fast forward a few years to Autumn 2020 and Paul is celebrating completing his 500th property sale, an outstanding figure representing the impressive success he has enjoyed as a selling agent. Since it opened in 2017, the Chiswick office has maintained its position as one of the top three agencies for sales agreed in W4 according to Rightmove, unsurprising with such a talented individual at the helm.

Paul’s intelligent approach to each home he lists and decision to work with just a small selection of hand-picked properties proves advantageous to clients. His ‘precision pricing’ and ability to perfectly match homes to buyers often result in sales being agreed entirely off market, before they’re ever marketed openly.

While the Chiswick office has already won several national accolades for the stellar service provided to clients, Paul has been individually honoured by The Estate Agent of the Year Awards over the past few years and most recently the ESTAS 2020 People Award.
