The rules surrounding leaseholds had already changed in June 2022, when ground rent was abolished for all new leases. This means that when you extend a lease, you will longer need to pay ground rent.  As well as this, there are set to be new leasehold reforms that can change how lease extensions work. The main one is that the extension term is being proposed to be increased from 90 years to 990 years. As well as this, the marriage value contributions are being discussed.  It will take a few years for these changes to come into effect, and these proposals will likely be diluted and reduced, so don't wait for these changes before extending your lease.
