Fears of a possible mansion tax under have caused growing unease in the property market, with estate agents reporting a surge of calls from concerned homeowners and buyers pulling out of deals.
Reports over the weekend suggested that Chancellor Rachel Reeves is considering a 1 per cent annual levy on the portion of a property’s value exceeding £2 million. That would mean the owner of a £3 million home could face a yearly bill of £10,000.
The speculation has already led to movement across London, with sellers trying to reduce asking prices ahead of the Budget on November 30. Buyers, meanwhile, are said to be delaying or cancelling agreed sales until there is more clarity.
According to industry figures, the number of agreed home sales fell by three per cent in September, marking the first annual decline since Covid. High-value areas have been particularly affected.
Estate Agents Report Nervous Clients
Becky Fatemi, executive partner at Sotheby’s International Realty, said her clients had reacted to the mansion tax rumours with “disgust… perceiving no incentive at all to be here.”
“Today, I’ve had a few phone calls from people saying, ‘Look, whatever price I need to sell at, just reduce it to that so I can get it away’,” she said. “But then I’ve got other clients who have told me, ‘Actually, I’m not going to sell. I’m going to wait for this Government to leave because there’s no way that they’re going to be able to sustain this kind of stupidity, and I’m just going to take my property off the market.’”
She added that the government was “shrinking the economy quite dramatically and breeding a stagnant swamp.”
Will Watson, head of London at property consultancy The Buying Solution, said uncertainty was now stalling transactions.
“Clients who were willing to exchange a contract before the Budget are now saying they’re not,” he said. “Until we know really what [the Government] is going to do, a lot of people will just sit tight.”
Property Shares Decline
Concerns over potential new taxes also hit the stock market. Shares in leading housebuilders fell on Monday, with Vistry dropping by as much as 1.9 per cent and Barratt Redrow by 1.4 per cent.
Government Yet to Deny Mansion Tax Plans
Housing Secretary Steve Reed declined several times to rule out the introduction of a mansion tax during media interviews this week. Asked directly whether the Treasury was considering the move, he said: “It’s best for me not to answer that question.”
Rachel Reeves, currently attending an investment summit in Saudi Arabia, said in an interview with Fortune Magazine that the Government was “looking, of course, at tax and spending to ensure that we both have resilience against future shocks… and that those fiscal rules are adhered to.”
Treasury officials are said to be facing a shortfall of around £30 billion in public finances. Reports also suggest the Chancellor may reconsider Labour’s manifesto pledge not to raise income tax, which could generate about £8 billion if reversed.
Industry Experts Warn of Impact
Property experts have warned that a mansion tax could fail to achieve its aims. Lucian Cook, head of residential research at Savills, said:
“There’s a big difference between someone in a £2 million house without a mortgage and someone with a sizeable mortgage. So it doesn’t necessarily capture net wealth at all.”
Neal Hudson, founder of housing data firm Residential Analysts, said the policy could have “some fairly negative impacts.”
“The top end of the market has been stagnating for the last decade already as it’s been hit by higher rates of stamp duty,” he added.
Wider Tax Reforms Under Review
Labour ministers have also indicated they are open to reviewing council tax and other elements of local government finance. When asked by the Conservatives whether the Government had made any assessment of the potential impact of a “house price tax,” Local Government Minister Alison McGovern said:
“The Government remains committed to keeping all taxes and elements of the local government finance system under review… and will consider options for reform where there is clear evidence that change would deliver better outcomes for residents and councils alike.”
Her comments mark a shift from her predecessor, Jim McMahon, who said in July that ministers had “no plans” to reform council tax.
Ongoing Uncertainty
With less than a month to go before the Budget, many in the property industry say uncertainty is the main factor holding back confidence. Sellers are reducing prices, buyers are delaying purchases, and investors are becoming cautious.
As one homeowner told agents this week:
“There’s no point trying to sell right now — everyone’s just waiting to see what happens.”
Let Us Know What You Think: The rumoured mansion tax may feel like a London issue, but uncertainty at the top of the market often ripples across the country. When confidence falls among high-value buyers and sellers, it can slow movement in the wider housing chain — from first-time buyers to downsizers.
So what about you? Are you thinking of selling or buying in the current climate? Will you be waiting to see what happens in the Budget — or do you believe this won’t affect your plans at all?
