Selling a home is one of the largest financial decisions most people make. The fact that so many people put it off for so long is not irrational. The barriers are real, the costs are significant, and the process is genuinely difficult.
Research from the HomeOwners Alliance published in 2025 found that one in five UK homeowners considered moving in the past two years but did not go ahead. The barriers they cited were high house prices, the stress of moving, moving costs, a lack of suitable homes to move to, and stamp duty. The Alliance estimates that around 800,000 homeowners shelved moving plans in the period covered by the research.
That figure represents a large population of people who have thought seriously about selling, reached a point where they began to act on it, and then pulled back. They are not indifferent to selling. They wanted to sell. Something stopped them.
Understanding what stops people matters because many of them will eventually sell. The intention does not disappear. It gets deferred. And when the deferral ends, when the thing that was stopping them changes, they move fast.
The financial barriers
The upfront cost of moving is substantial and often underestimated. Agent fees average around 1.42% of the sale price including VAT according to HomeOwners Alliance data. Conveyancing, surveys, removals, and any works required before listing add considerably to that. For homeowners moving into a higher price bracket, stamp duty is a significant additional cost. On a £400,000 purchase the stamp duty bill alone can reach £10,000.
Stamp duty was cited by 24% of those who shelved moving plans. The HomeOwners Alliance describes it as acting as a handbrake on the housing market, particularly for older homeowners who would otherwise downsize and free up larger family homes. When the cost of moving is measured against the benefit of moving, many people conclude the numbers do not work. So they stay.
Interest rates have added a further layer to this calculation. A homeowner who secured a 2% fixed rate mortgage in 2020 and has been considering a move faces the prospect of re-entering the market at significantly higher rates. For some, the monthly payment difference between staying and moving is large enough to make the decision straightforward. They stay.
The intention does not disappear.
It gets deferred.
The stress barrier
The stress of moving was cited as a barrier by 35% of those who shelved their plans. That figure matches high house prices exactly, which makes it the joint most commonly cited reason for not moving. It is rarely the primary reason given in public surveys because people feel it reflects poorly on them to cite stress rather than financial constraint. But it is real.
The UK property transaction process is long, uncertain and prone to collapse. Barclays research found that three in ten people who have been through a chain say they will delay moving for as long as possible as a result of the stress they experienced. That is a significant group of people who have decided, based on direct experience, to avoid repeating it.
The average time from sale agreed to exchange reached 123 days in 2025. For sellers who have been through this once, the prospect of spending four months in an uncertain chain again is a genuine deterrent. They know what it feels like. They know it can collapse at any stage. The rational response to that knowledge, for many people, is to stay put until something forces the issue.
The emotional barrier
Financial and practical barriers are easier to name than emotional ones, but research consistently shows that emotional attachment plays a meaningful role in the decision to delay selling.
For homeowners who have lived in a property for many years, the home carries a weight that is separate from its market value. Children grew up there. Significant events happened there. Leaving is not simply a property transaction. It is the end of a chapter, and many people take a long time to reach the point where they are ready for that.
This is particularly visible among older homeowners considering downsizing. The property may be too large, too expensive to maintain, and increasingly impractical. The rational case for selling is often clear. But the emotional readiness to leave can take years to arrive. In some cases it never does, and the person remains in the property until circumstance forces a decision their own will never reached.
Long-term empty homes increased by over 50% since 2016, reaching more than 300,000 properties by October 2025. A proportion of those represent cases where the owner is not ready to sell, or where the decision belongs to multiple people who cannot agree, or where the emotional weight of the property has made acting on it impossible.
Finding somewhere to go
Twenty-seven percent of those who shelved moving plans cited a lack of suitable housing as the reason. This is a barrier that receives less attention than cost and stress but is structurally significant.
Many sellers are also buyers. They cannot sell until they have somewhere to move to. If the properties available in their target market do not meet their requirements, or if the competition for those properties is too intense, the entire chain of decisions stalls at the purchase end. The seller may be entirely ready to sell. The buying market does not cooperate.
For downsizers, this takes a specific form. The supply of appropriate smaller properties, step-free homes, and retirement housing is limited relative to demand. Eighty percent of estate agents surveyed by HomeOwners Alliance agreed that not enough people are downsizing to free up family homes. The shortage of suitable destinations is both a cause and a consequence of that stasis.
What breaks the delay
Delay rarely ends because the barriers disappear. Stamp duty does not go away. The process does not become less stressful. The emotional attachment does not resolve itself. What changes is that something else arrives that makes staying harder than leaving.
A family outgrows the home. A job moves to a different city. A relationship ends. A parent dies and leaves a property that needs to be sold. A child reaches school age and the catchment question can no longer be deferred. Health changes and the current home becomes impractical. A financial situation shifts and the equity in the property becomes the most useful thing the person owns.
These are the events that end the delay. Not a change in stamp duty rates or an improvement in the conveyancing process. A life event that makes the status quo untenable.
When that happens, the seller who contacts an agent is not starting a slow exploration. They are acting on something that has been building for months or years. The decision was not made when the enquiry was sent. It was made long before. The enquiry is the evidence that it has finally been made.
That is why the context behind an enquiry matters as much as the enquiry itself. The seller who mentions a new job, a family change, an inheritance, a school deadline, or a health situation is not providing incidental detail. They are describing the event that ended the delay. That is the signal. That is what the enquiry is actually saying.
