There are two supermarkets mapped here, one at osm.org/node/11065351887 that has no details, and one at osm.org/node/11119031589 called "Website Designers London" that looks like a mistake and has various spammy tags. This area could do with careful resurveying.

https://london.eater.com/2019/8/29/20838366/taylor-street-baristas-london-cafes-black-sheep-coffee-administration suggests this is no longer a "Taylor Street Baristas" and so would benefit from resurveying

I'm fairly sure the petrol station mapped here as "Shell" is now branded "BP"

I believe Traid Links mapped here at osm.org/way/160510453 has closed, but I haven't checked this

I suspect the "Greenfield Shepherd Huts" mapped here at osm.org/way/1055089321 no longer exists

There's a cycle path mapped here as osm.org/way/669688779 that goes straight through a more recently added embankment by Mauls at osm.org/way/1098380785 - it seems unlikely that this is correct.
