With 50 yearsâ experience and an established independent network, we can open doors that others don’t even know about, while our personal approach simplifies the entire process.
Harwood Advisory redefines the UK prime property market by reacting quickly to consistently deliver what you need at the right price, in the best time â with every unique need met intuitively along the way.
What our Clients Say
â S.LÂ I would say Harwood Advisory is so much more than an agency, they are a top-class outfit.I view Ollie and Sami as advisors, and I trust their insights implicitly. Selling our house was not an easy process, due to election, budget reviews and many other factors but Harwood Advisory worked tirelessly through it all, are dynamic in their approaches and I could not recommend them more highly!
My mind was not really convinced to sell at that point but after Ollie had viewed my property and we had a further conversation I knew that Ollie was head and shoulders above the rest. Ollie has a vast knowledge in his field, is incredibly committed to what he does and gets the entire process over the line in record time. He is not only your agent, but becomes a good friend and not only cares but is honest and realistic.
Ollie speeds up the conveyancing process which can be very frustrating when selling or buying and guides you through every step of the way. My only wish is that there were more agents in the world like Ollie.
â M.H
We instructed Sami to sell our London apartment which had been on the market without success. Sami revitalized the process with fresh vigor, fresh approach and great energy. He achieved a sale in a short period and at a great price. Many thanks Sami – we would recommend you to anyone wanting a result.
â M. R
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.
â R. M
Sami was a god send. Without him, we would not have crossed the line and closed the deal. Professional, courteous, unflappable and patient probably best describe Samiâs performance on the job. He negotiated, to use the sellerâs agentâs words, a âHerculeanâ price and brought us to completion within 6 weeks.
â K.R
My husband and I met Sami four years ago and when we decided to sell our Kensington home after 39years, we appointed Sami without hesitation. Sami had setup Harwood Advisory with a highly experienced colleague, Susannah Fox, and they make a perfect teamâalways 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 and we will remain in touch for their wise advice and for future property transactions.
â M.C
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.
â M.R
Dealing with a purchaser and four different people selling, needed great patience, diplomacy and tact. It canât have been easy putting together the sale of the entire house, but Sami made it look pretty seamless and relatively stress free.
â A.O’R
As we reside in Russia, selling our London apartment demanded a lot of personal attention. Sami truly went the extra mile-undertaking lots of viewings during the selling period, many in his own time. The quality of his work was quite outstanding.
â Y.L
I trust Sami completely. Having known him for five years, I already respected his behaviour. When I needed an expert, he was my number one choice. We placed complete trust in him for his loyalty, discretion, attention to detail and listening ability. He is a very clear communicator and successfully opened doors we never knew existed.
â J.T
Susannah acted as our country buying agent. She went above and beyond to follow our ever changing brief. Susannah was unwavering in her determination, patience and attention to detail. She provided an entirely professional service. We would never have discovered our property without Susannah on board. Post completion Susannah remained on the scenes. There are no loose ends as far as Susannah is concerned and we could not have wished for a smoother process. Thank you to Susannah and to Harwood Advisory. Highly recommend.
â Mr and Mrs T
â R.OWell done Sami. Iâm satisfied with the outcome and the team was excellent. It could have been a difficult few months and that has been avoided. Thanks for all your persistence and guidance. Youâre still the King of AG!

Introducing Harwood Legends
There are certain people who donât just operate in the market, they help shape it.
For Harwood Advisory, Brigadier Browne is one of those people.
Not a traditional property operator. No textbook playbook. No conventional route in. But what he brings is something far more valuable in the world of super-prime property.
Relationships.
Decades of trust, credibility and connections built properly, maintained properly and called upon at exactly the right moment.
In a market where many of the best opportunities never reach the open market, access matters more than ever.

The homes you donât see are often the ones worth knowing about.
Across the South West, many of the finest properties never reach the open market. Theyâre shared quietly, through trusted networks, and secured before theyâre ever publicly listed.
Through Claire and Susannahâs established relationships and on-the-ground presence, our clients gain access to these opportunities early, often before theyâre even considered âavailable.â
Itâs a more discreet, more considered way to buy.
If youâre looking beyond London, weâll keep you one step ahead.
Contact Claire or @susannahfoxproperty at Harwood Advisory.

A different kind of search.
Somerset and Dorset each offer something completely unique. From rolling countryside and historic market towns to coastal escapes and private rural estates, finding the right property here requires more than just portal alerts.
Thatâs where Claire and Susannah come in.
With extensive experience across the South West and a highly personal, relationship-led approach, they provide genuine local insight, trusted connections, and access to opportunities that are often never publicly marketed.
Itâs not just about finding a home, itâs about securing the right lifestyle and making the process feel effortless from start to finish.
Get in touch with Claire or @susannahfoxproperty to start your search.

From coastal retreats in Dorset to countryside homes in Somerset, weâre helping buyers secure exceptional properties quietly, discreetly, and often before they ever reach the open market.
If youâre considering a move, or even just exploring the idea, itâs worth having the conversation.
