Harwood Advisory

Sami Robertson’s  Harwood Advisory  is a boutique full-service prime property  firm of three tried and tested property professionals with over 50 years of prime property knowledge and an enviable track record of delivering success for their clients. 

In a world where exceptional client service is often promised but rarely delivered, Harwood has redefined the property transactional experience of its clients by constant application of its core client-centric ethos. 

Core attributes of Harwood’s client service model are total confidentiality, mastery of the client’s brief, unimpeachable market access including to the secretive but deep pools of ‘off market’ prime properties which opens doors closed to most other agents and market participants, and the Team’s unrivalled market acumen which enables a laser focus on price and pricing.  

Since its inception in 2020 Harwood has led over £175 million of successful property transactions to the delight of its clients. The successful transactions covered: 

  • Retained Search for London’s prime properties 
  • Sales of London’s prime properties 
  • Country house search and sales 

There is nothing passive about Harwood’s execution of its mandates: they are all performed with unerring focus and sustained intensity. Success is not an accident but the inevitable result of the combination of its core ethos.  

Harwood is retained by HNW clients who wish to blend transaction privacy with transactional success. They know that Sami’s word is his bond, Harwood transactions do not leak but still get done. The customer journey is seamless with a no hassle approach. AML is delivered slickly and quickly through its retained AML specialists, London CDD. Sami’s clients receive regular, concise, informed reports eliminating ‘surprises’. Hard work and dedication bring their own results.

Testimonials abound: 

Prime Property Retained Search  

‘As soon as the market opened for business during COVID-19, Sami managed to agree terms on one of the best off-market houses in the most sought-after UK location. But he went so much further - in also helping to find a tenant for my London apartment in the process. Truly brilliant service.’ M.R. 

‘Sami was a godsend. Without him, we would not have crossed the line and closed the deal. Professional, courteous, unflappable and patient probably best describe Sami’s performance on the job. He negotiated to use the seller’s agent’s words a “Herculean” price and brought us to competition within 6 weeks.’ K.R. (Singapore)  

Prime Property Sales 

‘Harwood Advisory are a boutique real estate agency which draws from its extensive knowledge of the super prime sector. We are so glad that we moved away from the large international agencies that represented us before.’  R.M. (Sale of Penthouse, Hollandgreen) 

‘My husband and I met Sami four years ago and when we decided to sell our Kensington home after 39 years, we appointed Sami without hesitation. Sami had set up Harwood Advisory with a highly experienced colleague, Susannah Fox, and they make a perfect team – always going the extra mile.  Sami and Susannah sold our house in an off-market process that utilised their longstanding, international network of property professionals. It was a huge success.’ M.C. (Sale in Camden Hill Square)
