The private market in London: what it is, who it's for, and how to access it

The market you don't see on Rightmove

If you've been searching for property in prime central London using the major portals, you've been looking at a partial picture.

A meaningful percentage of high-value London property — the exact figure is difficult to establish precisely, but from our own transaction data it's consistently above 30% — never reaches a public listing. It moves privately, through conversations between brokers and buyers who have made the right relationships at the right time.

This isn't a secret, exactly. It's more that it isn't discussed openly, because the people who benefit from it have limited incentive to advertise it and the people who don't know about it don't know to ask.

Here's how it actually works.

Why sellers choose the private market

The reasons vary, but they fall into three broad categories.

Privacy. For high-profile sellers — executives, public figures, people with assets that attract attention — the idea of their home appearing on a public portal, with interior photographs and precise location details available to anyone with a browser, is genuinely uncomfortable. The private market allows a transaction to happen without that exposure.

Control. A private sale can be structured to reach a specific buyer profile without the noise of a public launch. No price reduction history visible to the market. No days-on-market counter ticking upward. No public record of interest levels or lack thereof. For sellers who understand how market perception affects value, that control is worth paying for — or rather, worth accepting a slightly reduced buyer pool to achieve.

Relationships. Some sellers simply prefer to transact with buyers they know something about — buyers who have been vetted, who are financially qualified, who come with a recommendation. The private market, at its best, is a network of qualified principals operating with a level of trust that the public market can't replicate.

Who accesses it and how

The honest answer is that the private market is accessed through relationships — specifically, through relationships with brokers who maintain active buyer registers and have enough credibility with sellers to be trusted with off-market instructions.

At Aurum, we maintain a brief register of active buyers — people who have had a detailed conversation with us about what they're looking for, who are financially qualified to complete, and who we know well enough to approach with a specific property without wasting either party's time. When a seller approaches us with a property they want to move privately, we work through that register first.

The process is straightforward. The buyer receives a confidential introduction — address withheld initially, full details shared under NDA if there's interest. If the fit is right, a viewing is arranged privately. If an offer follows, it proceeds through normal legal channels. The difference from a public sale is everything that happens before the offer — the introduction, the qualification, the discretion.

What it takes to be on the right side of this

For buyers, access to the private market requires demonstrating three things.

Seriousness. Brokers who operate at this level are protective of their seller relationships. They won't introduce a buyer to an off-market property unless they're confident that buyer will behave professionally — respond promptly, view seriously, make decisions rather than hedge. One introduction that goes nowhere without explanation tends to close doors.

Financial clarity. In the private market, financial qualification isn't a formality — it's a prerequisite. Sellers who are transacting privately are often doing so precisely to avoid the uncertainty of a public process. Proof of funds, clarity on financing, readiness to exchange within a defined timeframe — these are expected upfront, not after the offer.

A genuine brief. The buyers who get introduced to the best off-market opportunities are the ones who have articulated clearly what they want and why. Not just bedrooms and postcodes — the specific characteristics of a property that would make it the right one. Brokers match briefs to properties. The more precise the brief, the more useful the match.

The practical reality

The private market isn't a shortcut to better properties at lower prices. Off-market properties are priced at market value — sometimes above it, because sellers who don't need to publicly list tend to have less pressure to negotiate. The advantage for buyers isn't price — it's access, and the elimination of the competitive dynamics that a public listing creates.

For the right buyer, in the right area, with the right brief — the private market is worth understanding and worth accessing. The way to access it is the same as it has always been: find the right broker, have the right conversation, and demonstrate that you're worth introducing to.
