As pioneers we set the standard

    In 1991 Johnny Bergius, the founder of Gretton Bergius, was among the first innovators to develop the service of acting solely for buyers of residential property. Now, as one of the most established, highly respected property search agents in London, Gretton Bergius are widely acknowledged to have unrivalled experience of acquiring property both in the UK and across the globe. Our history, gravitas and depth of knowledge are priceless assets in supporting our client’s property search. Based on principles we identified many years ago, we remain an organization who do not sell property, a highly important distinction. This dedicated focus on one side of the transaction neatly removes potential conflict of interest between buyer and seller.



    Reputation is our most prized & protected asset

    Gretton Bergius have a reputation for an exceptional depth of expertise having acquired some of the globes most extraordinary property and acted for some of the most notable people of our time. Our reputation for skill, knowledge, integrity and discretion are widely acknowledged by our peers, the service providers with whom we collaborate but most importantly by our loyal clients past and present.



    Knowledge is a rare commodity

    There are very few who can claim the breadth and depth of our knowledge of global property acquisition. Since 1991 we have provided the knowledge to support property acquisition predominantly in London and the UK but also from Ibiza to Cap Ferrat, the West Village to The Alps, Sardinia to Beverly Hills and Dallas to Deia.

    Whether it’s a flat for your children, a country home for your family, a pied a terre for convenience, a house on the beach, a palace for indulgence or building a portfolio for prosperity, we have the time, the patience, the experience and above all the knowledge to guide you through this complex process.



    Patience prevails

    Anyone can find you a property but few can or do manage the transaction with patience as your ally.  As a well-resourced, long established and well capitalised business, Gretton Bergius can afford to be patient. Attention to detail, thorough analysis, pre-empting problems however monumental and doing our best to provide wise solutions are the keys to our success.  We may be strident in our approach but you are at the forefront of everything we do.  We are here to protect you and protection requires patience.



    Collaboration determines success

    Collaboration is one of our most important aspirations. Mutual respect and a collaborative approach are vital to the successful outcome of every transaction. We are part of your team. We have collaborated over many years with some of the globes most respected family offices, legal and financial teams, trust companies, surveyors and other advisors. To them we are a vital property information resource. Reassured by our experience and profound understanding of London, UK and global property markets and having handled a multitude of unforeseeable issues which have arisen in many jurisdictions, we are welcomed as critical team members. We focus on collaboration ensuring we arrive at the optimum outcome for the purchaser, you, our mutual client.



    Relationships are built over time

    We thrive on relationships, many of our clients have favored us with their instructions for multiple acquisitions in varied locations over many years. We are equally proud of the professional relationships we have patiently built on mutual trust and success over the years. We foster and nurture relationships to ensure our clients receive the best chance of success in negotiations. Our close relationship with agents and their understanding of the skill, preparation and advice we present to our clients prior to offering and throughout the process, give confidence to vendors. This meticulous relationship based strategy has repeatedly and undoubtedly ensured our clients are considered before others in competitive situations.



    Discretion is our core value

    Having acted for a broad profile of clients including some of the globe’s most notable people we, quite simply, eschew promotion or attention in the press or media of any sort. We are admired for our longevity, experience, consummate skill and reputation, not through our client base, industry awards or connections.

    Maintaining discretion and avoiding any form of external attention gained from our achievements on our client’s behalf are the fundamental foundations of everything we are and aspire to be.
