The issue is a long-standing one for the Conservatives under leader Kemi Badenoch, who has pledged the party would take action on the tax if voted back into power.

In October 2025 Badenoch called stamp duty a “bad tax” that gummed up the housing market.

The latest petition also seems to be an information-gathering exercise for the Conservatives, as it also asks which party signatories voted for in the 2024 general election and how they will vote in the next one.

Homebuyers paid £899 million in stamp duty in January 2025, according to the latest HMRC statistics – up 6% from the £848 million paid in January last year.

Last year, homebuyers paid £15.4 billion in stamp duty – an 18% rise from the £13 billion paid in 2024.

The increase was largely due to the nil-rate thresholds falling from £250,000 back to £125,000 last April.
