OpenStreetMap
Ordnance Survey is great, but it’s not fast. Ordnance Survey’s Mastermap isn’t updated regularly enough to have captured the extension to my house, constructed two years ago. Hopefully, one day, the local planning authorities will find a way to connect their new construction sign-offs to those updates - a kind of bricks-and-mortar blockchain. For now though, if Mastermap isn’t going to put the right polygon in place, then I’ll have to learn how to do it with OSM. Perhaps the really neat and tidy areas of the UK OSM correlate to the hometowns of GI-related employees?

Welcome to the club, MerrynW! Thanks for your edits. I hope you like it here, and continue to contribute.
One resources I think new users can benefit from is Learn OSM. It is a great place to learn the basics of editing, and their more advanced articles go much further than the basics
Another good resource, for new editors and long time contributers, is the OSM wiki. It’s usually the first place I’ll look for info. If the wiki doesn’t answer your questions try posting it to the OSM help site.
I hope those look useful to you, and happy mapping.

Yep, welcome. I find places well mapped if there are one or more mappers who take particular interest in that area. They may be ‘locals’ or have some connection there. Map things of interest to you - places you like will probably be attractive to others. Plans .. while they might have been approved some times don’t get built, or not build quite to plan so while it might be good most of the time to process planned stuff to a map there should be room for correcting that map to ‘ground truth’. There are ‘talk groups’ that might get you in contact with other local mappers too. osm.wiki/Mailing_lists#Country-Specific_Lists
Good luck.
