The research project
This was an announcement of research, published on 1 Oct 2018. It does not say a blockchain was in use as the land register.
HM Land Registry was exploring how blockchain technology could be used. It was partnering with the software company Methods, which would use R3's platform, Corda, for the second phase of a research and development project called Digital Street. Methods would be supported by R3, Blockchain Digital, and their wider partner network. A tender for that support had attracted 22 bids.
Digital Street, then in its second year, was exploring blockchain technology and smart contracts. The project had already created a digital register for a small selection of properties, as a first step towards a register that a computer can read in full and update at once. That digital register is not described as a blockchain.
The Local Land Charge Register brings data from 326 local authorities into a central database. That is a different record from the research.

Technical detail
The announcement calls Corda a blockchain platform. “Fully machine-readable and able to be updated instantly” is its phrase for the register it was aiming at. Quotations from the firms, and an account of a digital mortgage service, were not used. The page also gives 2018 figures for the value of property on the register. A later strategy has its own figures, so those were not used.
