New research carried out by Jackson-Stops has revealed that stamp duty relief for downsizers would almost certainly deliver an immediate boost to housing supply and wider economic activity.
The estate agency looked at the impact of the prohibitive property tax on older homeowners and found that over a fifth (22%) of over-55’s never plan to downsize. However, among those who do intend to move, 15% said they would do so within the next year if stamp duty were reduced or removed on their onward purchase – the equivalent of 505,000 homes potentially released onto the market within 12 months.
Looking slightly further ahead, 41% said they would downsize within two years under the same conditions, representing 1.4 million older home movers across England waiting in the wings (see Table 1, P.3)[3].
The findings combine data from the English Housing Survey with responses from 2,000 homeowners aged 55 and over across England. The headline figures are modelled only on those who expressed an intention to downsize from their main residence. These respondents were then asked how stamp duty relief would affect the timing of their decision.
Nick Leeming, chairman of Jackson-Stops, commented: “Stamp duty is acting as a brake on the housing market, keeping older homeowners in properties that no longer suit their needs and blocking supply for younger families. Our research shows that stamp duty concerns rank alongside the stress and cost of moving as key obstacles preventing older homeowners from downsizing, with over a quarter citing it as making downsizing financially unattractive.
“With the right incentive, such as targeted relief on stamp duty for downsizers, over half a million people are willing to move in the next 12 months. In total, 2.8 million over-55s across England say they would downsize if stamp duty were reduced or removed, revealing the true scale of pent-up demand being held back by current tax policy. At a time when the Chancellor faces pressure to boost tax revenues, carefully designed stamp duty relief for downsizers could offer a valuable short-term solution – stimulating market activity, releasing homes, and generating additional tax receipts that might otherwise be delayed or lost.”
Jackson-Stops has projected the number of homes that would come onto the market over a five-year period if stamp duty relief was provided to downsizers.
The data indicates that 1.8 million homes would be released within three years, rising to 2.5 million properties by year five (See Table 1). The research found that London, the East of England, and the South West would see the greatest stock released.

Timeline | No. homes released to market (cumulative each year) |
Within 1 year | 505,000 |
Within 2 years | 1.4m |
Within 3 years | 1.8m |
Within 4 years | 2m |
Within 5 years | 2.5m |
With 5+ years | 2.8m |

One in five homeowners over 55 would downsize if there were more homes specifically designed for older people available, rising to 28% and 27% in the East Midlands and Yorkshire & the Humber, an indication of the lack of age-appropriate stock in these regions. The findings come as the government’s Older People’s Housing Taskforce works to expand suitable housing supply across the nation.

A fifth (21%) cited wanting to relocate as a key downsizing driver, peaking at 27% among younger downsizers (55-64 year olds). South East residents showed the strongest desire to move location when downsizing (25%).
Leeming continued: “Potential downsizers are out there and looking, but many still lack a driving reason to move from window shoppers to serious movers. This is often a generation of people who have lived in large family homes for many decades, finding themselves years later as accidental millionaires in which the value of their estate has largely been built on silent house price inflation and capital preservation.
“In reality, the combined costs of tax, removals, administration and legal fees create a significant mental and financial barrier compared to what they likely faced in their last move. As the government’s Older People’s Housing Taskforce works to expand suitable supply, government also needs to address these barriers to truly unlock market movement – the UK is significantly behind other nations in planning for older people’s housing.
“If we want to encourage greater fluidity in the market and free up larger homes for growing families, reducing the cost of moving would be a good step. More sales stock would improve affordability for younger buyers looking to upsize, supporting intergenerational fairness and boost market activity to support economic growth.”
Since 1st April 2025, the cost of stamp duty increased for homebuyers when the temporary changes to the tax thresholds that were put in place in September 2022 came to an end. The ‘nil rate’ band for home movers moved from £250,000 back to £125,000, estimated to impact hundreds of thousands of purchases. The UK continues to have the highest property taxes of any advanced economy around the world, with the stamp duty bill paid by the purchaser on completion of their transaction.
For downsizers, currently stamp duty rates are progressive, ranging from 0% to 12% depending on property value. As an example, a property priced at £500,000 would incur stamp duty of £15,000, calculated on the progressive bands up to 5%. Nationwide data reveals UK house prices have increased by 237% since 2000; an unprecedented rate of incline that has far outpaced the wider economy and dragged the cost of tax up with it. For many, this makes the real cost of moving to a smaller home feel much larger, acting as a reason to stay put.
