Rachel Blake, a Labour MP and former Treasury minister, warns against reducing the mansion tax threshold from £2 million to £1.5 million, arguing it would unfairly target family homes. According to Hamptons analysis, lowering the threshold would double the number of affected homes to 272,000, with nearly 80% located in London and the South East. Blake expressed concern about unintended consequences, particularly for homeowners whose property values have increased significantly over time but who may not be able to afford additional taxes.

Story summary

A Labour MP, Rachel Blake, has warned against lowering the mansion tax threshold to £1.5 million from its current level of £2 million. This change would result in twice as many homes being affected, increasing the number from 136,000 to 272,000 properties. According to analysis by estate agents Hamptons, one in four detached homes in London would be impacted under the new threshold. The majority of these homes, nearly 80%, would be located in London and the South East region. Blake, who is a former Treasury minister and MP for Cities of London and Westminster, expressed concern that this change could unfairly target family homes. Rachel Reeves previously introduced a council tax surcharge on properties valued at £2 million or more, which will take effect from April 2028. John Healey, Reeves' successor as chancellor, is reportedly considering the reduction to address revenue needs for the Treasury.
