Zoopla's new data reveals that nearly half of British homeowners conduct covert property research without informing their partners, with London leading the trend.
The Art of the Covert Search
The methods used to keep these searches from partners are surprisingly detailed and specific. The research shows that 38 per cent of those conducting secret property searches have done so while watching television with the very people they are keeping it from. This suggests a level of casual confidence that the other person is too absorbed in the programme to notice the phone in their hand.
Other tactics are more overt in their concealment. Eleven per cent turn their phones away from view when the door opens. Ten per cent wait until their partners are asleep to browse listings in the quiet of the night. Nine per cent admit to deleting their browsing history, a digital cleanup that highlights the fear of discovery. A further eight per cent quickly close property websites or apps when someone enters the room. These are not casual habits. They are active measures of concealment.
London Leads the Secrecy
Geography plays a significant role in this behaviour. London recorded the highest rate of secret property research, with 62 per cent of residents having taken property-related actions without informing other household adults. The West Midlands followed closely at 54 per cent, with the North West at 53 per cent. These figures suggest that in high-cost areas, the pressure to find a better deal or a better location is so intense that it fuels private investigation.
The concentration of secrecy in London is likely linked to the complexity of the market there. With higher prices and more varied stock, the temptation to explore options in private is stronger. It is a market where every pound and every postcode matters, and where the gap between current status and desired status can feel insurmountable without careful, private planning.

The Property Crush Phenomenon
Among those considering a purchase within the next one to three years, the proportion of secret activity rises significantly. The research indicates that 72 per cent of this group have taken at least one property-related action without informing their household members. This is a massive shift from the general 44 per cent figure, showing that the closer one gets to a potential move, the more likely they are to keep it to themselves.
One of the most striking findings is the concept of a 'property crush'. The research shows that 23 per cent of those planning a purchase have developed a romantic attachment to a specific home. Nineteen per cent have saved or shortlisted properties in secret. This is not just rational calculation. It is an emotional investment in a potential future, often kept hidden until the moment is right to share it.

Why the Secrecy Matters
Richard Donnell, Executive Director of Zoopla, notes that anyone thinking about buying a home today has more to weigh up. Higher mortgage rates are limiting buying power, but there are more homes for sale, giving buyers greater choice and more room to negotiate. This complex landscape makes the private research phase even more critical. It is a time for careful assessment of affordability and value before the conversation begins.
Donnell adds that house prices and market conditions vary widely across the country, and even between neighbouring areas. Buyers should not rely on the national picture when working out their next move. This advice underscores the need for detailed, localised research, which is often best done in private to avoid premature discussion or pressure from well-meaning partners.

The Implications for Couples
The rise in secret property research suggests a shift in how couples approach one of their biggest financial decisions. It is no longer a joint, open-ended exploration. It is a solo mission, often driven by one partner's desire for change. This can lead to surprises, both positive and negative, when the secret is finally revealed.
For the industry, this means that the initial stages of the buying process are often more individual than previously thought. Estate agents and mortgage brokers may be dealing with clients who have already done significant private research. Understanding this dynamic is key to providing the right support and advice at the right time.
