Very good Just about good enough
Future .....
• An address frame suitable for Census 2021
but also ... social surveys, business surveys, Admin Data Programme - & Government Statistical Service
• Maximise the use of existing datasets
(National Address Gazetteer, Open data ???)
• NOT ONLY A MAILING LIST • A probabilistic frame for linking other sources

And some other stuff ...
• Proper use of GI / aerial photography etc(QA / automatic change detection etc)
• OS portal / API – for field / public QA
• Self linking to address-list ???
• Wiki / crowd sourcing for CEs etc
• Opendata – CEs & attributes (linked to national frame)

What I care aboutOpendata
‘NAG’OS
A single, maintained, funded national list should be part of the national digital infrastructure
Very supportive of open data for communals and attribution of addresses – but there should only be one national address list – a competing open data list has potential to lead to 2 classes of citizens and add inefficiency and confusion – could take us backwards when we were getting so close
