Nearly one in five people moving home have paused their plans ahead of Chancellor Rachel Reeves’ Autumn Budget, according to Rightmove.
The research was based on a study of over 10,000 people either in the process of moving or considering it.
17% said uncertainty around property tax changes had led them to put their plans on hold.
61% of respondents said they were aware of rumoured property tax changes, and 72% of that group said they were concerned.
Concern was highest among people aged 55 and over, with 81% worried about the impact of possible reforms, especially those targeting higher-value homes.
The South East and South West showed the same level of concern.
Colleen Babcock, property expert at Rightmove, said: “Our latest House Price Index showed how market activity is being affected by the various property tax rumours being discussed ahead of the Budget.
“Now, we’ve heard directly from home-movers about how it’s denting their confidence, with some preferring to wait until after the Budget to see how any policy announcements affect their plans.
“While most movers are carrying on as normal, it demonstrates how unhelpful the uncertainty over potentially costly changes can be.”
Babcock added: “I think most are now fed up with the rumours and would like to see the final contents of the Budget and assess how they’re impacted.”
Mary-Lou Press, president of NAEA Propertymark, said: “When rumours about potential tax changes in the upcoming Budget lead almost one in five movers to pause their plans, it’s a clear sign that confidence is fragile.
“For many households, moving home is one of the biggest financial decisions they will ever make, and unexpected costs, real or anticipated, naturally weigh heavily.
“What we’re seeing is people taking a ‘wait and see’ approach, particularly in regard to older homeowners and those in higher-value regions, where the impact of any change could be greater.”
Press added: “While most movers are continuing as normal, a slowdown in activity from even a small proportion of buyers and sellers can reduce choice in the market and lengthen transaction times.
“This can create a ripple effect, especially for chains relying on downsizers or those selling homes at the upper end.
“In the current climate, consumers benefit from taking advice early, understanding all their potential costs, and keeping in close contact with their agent.”
She said: “Market conditions remain varied across the country, and well-priced, well-presented homes are still attracting interest.
“For those ready to move, there continue to be good opportunities, but this report highlights why clear information and timely guidance are more important than ever.”
