I just found this from a quick google online so there is more information out there. The temporary increase is due to end on 31 March 2025, meaning that any transaction which completes thereafter will be subject to the increased rates of Stamp Duty. While this date might seem far away, buyers and sellers alike ought to be aware that an average residential property transaction takes between 12 and 16 weeks to complete, but can, in certain circumstances take much longer.

By completing before the Stamp Duty changes come into effect, a buyer can save a significant £2,500. This is the same for second homeowners (investors) and companies.
