The announcement is the latest in a series of Conservative policy proposals aimed at affluent middle-class voters who abandoned the party at the last election. Other measures include support with childcare for those earning over £100,000 and repealing the mansion tax.
Badenoch framed the inheritance tax plan as a reward for hard work and saving. "My ambition is to abolish inheritance tax altogether, as soon as we can afford it," she said. "I believe the people who work hard and save should be rewarded for that effort." She added: "So this is my guarantee: no stamp duty when you buy your home, no mansion tax when you live in your home, and no inheritance tax on your home when you pass it to your children or grandchildren."
But critics were swift to condemn the proposal. Tax Justice UK said in a statement: "Kemi Badenoch has just announced a massive inheritance tax giveaway to some of the wealthiest people in Britain. This is a reckless policy that will deprive public services of cash when they most need them."
Reform UK's finance spokesperson, Robert Jenrick, claimed the plan would affect only 2% of houses, the majority in London, adding: "The Tory party is looking after its own in Kensington, Reform is looking after the country."
Labour chair and cabinet minister Bridget Phillipson said: "The Tories haven't changed. Kemi Badenoch has shown that the Tories' choice is to do nothing to help ordinary families struggling with the cost of social care, prioritising the wealthiest instead."
TUC general secretary Paul Nowak called the policy "the same old Tory playbook: cutting taxes for their rich mates and leaving working people to pick up the bill." He noted that 95% of estates pay no inheritance tax, adding: "They are a party for inherited wealth, not workers."
The policy also raises concerns about overheating the housing market, as elderly homeowners may be incentivised to remain in large family homes rather than downsize.
