Prime central London property market: a buyer’s guide
Prime central London has spent more than a decade going sideways. Prices in the districts around Hyde Park peaked in 2014 and, allowing for inflation, have been drifting lower ever since. For anyone paying in dollars, dirhams or Swiss francs, that makes the best housing stock in Europe cheaper than it has been for a generation. It does not make it easy to buy well.
What counts as prime central London?
There is no official boundary. Most people in the business mean the postcodes that ring Hyde Park and Green Park: Mayfair, Belgravia, Knightsbridge, Kensington, Chelsea, Marylebone, St John’s Wood and Notting Hill, with Regent’s Park and parts of Holland Park added by those with a generous pen. Around that core sits a second ring of prime outer London, from Hampstead and Highgate in the north to Fulham, Wimbledon, Richmond and Dulwich further out. The two behave differently, and a buyer should know which market they are in.
The central ring is where international money lands. It is also where the most expensive mistakes are made, because the difference between a good building and an ordinary one on the same street can be 30% of the price.
Why have prices in prime central London stalled?
It was not one thing. Stamp duty rose in steps from 2014, with extra charges added for second homes and then for non-residents. Brexit removed a certain confidence. The pandemic emptied the centre for two years. Interest rates went from almost nothing to the highest in fifteen years. The long-standing non-dom regime was closed in 2025 and replaced with a residence-based system that brings worldwide assets into inheritance tax after a period of UK residence. Each of these took a few percentage points off demand, and together they held the market flat while the rest of the country moved.
Property taxation remains a live political subject, and it is fair to assume the rules will keep changing. I tell clients to underwrite a purchase on the tax position as it stands today and to hold the asset long enough that the next change is one of several they will see, not the only one.
Is prime central London good value now?
In relative terms, yes. Against New York, Hong Kong or Geneva, a well-located London flat now costs less per square foot than it did ten years ago, and sterling has helped dollar-based buyers further. The government’s own house price index shows Westminster and Kensington and Chelsea averaging well below what most overseas buyers assume a central London home costs. The averages hide a great deal, but the direction is clear.
Value and momentum are different things. Transaction volumes in the middle of the market have been recovering, while the top end above £5m has been quieter, with wealthy buyers waiting to see the outcome of tax and political questions. In our experience that pause is precisely the moment a patient buyer should be looking, because sellers who need to sell will deal.
How much can buyers negotiate?
Prime central London is a buyer’s market and has been for some time. More than half of the homes that come to the open market see their asking price cut before they sell, and the reductions are steepest in the centre. Bayswater, Maida Vale and South Kensington have seen double-digit discounts on the original guide. In prime outer London, where family houses are scarce, the gap between asking and achieved is far narrower.
An asking price is a negotiating position, not a valuation. Across our own acquisitions since 2006 we have paid, on average, 12% below asking. That figure comes from doing the work: knowing what the last five comparable sales achieved, why this seller is selling, how long the property has been sitting and what the agent has been told to accept. Bid without that evidence and one of two things happens. You overpay, or you offend the seller and lose the property to somebody who did their homework.
What are buyers looking for in prime London?
Family houses in the best neighbourhoods, close to good schools and with somewhere for the children to run, remain the most contested assets. Flats are easier to buy. A finished, lateral apartment in a well-run building with a lift will always find a buyer; an unmodernised one on a short lease, or in a block with a service charge dispute, will not.
Since the pandemic the appetite for a project has fallen away. Building costs have risen sharply, planning is slow and most buyers want to move in, not manage a contractor. The result is that turnkey homes carry a premium and unmodernised ones are cheap. I have made a business out of buying the second kind, so I say this with some feeling: for a buyer who has the patience and the right team, the discount on a property that needs work is the best value in the market. For a buyer who does not, it is a trap.
Transport has returned to the wish list now that most people are back in the office for part of the week. Proximity to the Elizabeth line, in particular, has added measurable value to Bayswater, Paddington and Marylebone.
Who is buying in prime central London?
The mix changes with the currency and the news. American buyers have been unusually active in the last two years, looking for a stable jurisdiction and a familiar legal system. Buyers from the Gulf continue to favour Mayfair, Knightsbridge and Belgravia. Our own client base has always been weighted towards Italy and continental Europe, family offices and private investors who want a London base for the family and treat it as one holding within a wider balance sheet.
St John’s Wood deserves a mention. It sits on the edge of the central ring, has the houses, gardens and international schools that families want, and has held its value better than almost any prime postcode through the difficult decade.
Why is buying in prime central London so hard?
Because the market is fragmented and the best of it is invisible. Something like seventy agencies sell property in the central postcodes, from global firms to one-room specialists on a single square. No portal shows the whole picture. A meaningful share of the finest homes, perhaps a third, change hands without ever being advertised, sold quietly through agents’ contacts to buyers who are known to be able to complete. In our own acquisition work, 78% of purchases have been secured off-market.
Add to that the specifics. Two mansion blocks on the same road can be run to entirely different standards. A ground-floor flat may sit above a Tube line and vibrate every three minutes. A lease with 70 years left is a different asset from one with 120. And the selling agent, however courteous, works for the seller.

Frequently asked questions
Is now a good time to buy in prime central London?
For a buyer holding for five years or more, the combination of prices below their 2014 peak, a weak pound and motivated sellers is as favourable as it has been in a decade. Nobody can call the bottom. The sensible approach is to buy the right property at the right price and let time do the rest.
How much below asking price should I offer?
It depends entirely on the property and the seller. Some homes are priced to sell and will go at or above guide; others have sat for a year and will take 15% less. The evidence, not a rule of thumb, should set the offer.
Which areas of prime London have held their value best?
Family-house districts with good schools and green space, such as St John’s Wood, Hampstead, Holland Park and the Chelsea squares, have proved most resilient. Areas dominated by investor-owned flats have been softer.
Do I need a buying agent for prime central London?
If you are buying from overseas, buying above £2m or want access to unadvertised stock, a buying agent will usually save more than the fee. Our success fee is agreed in writing before we start, with no retainer, and is only payable on exchange.
