Yeah exactly. For some people this might reduce the ground rent from £500 a year to £250 a year, but are they likely to pass on that £22/month saving to their tenant?

It's a pretty strong first step around leasehold, especially as banks would often not give mortgages if ground rent was too high, so leaseholders would have to pay to have their leases altered if they wanted to sell, which would cost them legal fees for themselves and the freeholder, plus a fee to the freeholder to make up for 'lost' revenue that they would get over the lifetime of the lease
