I too moved from 123-reg due to the price hikes.
I ended up on DreamHost…but have since found that Google only charge £10 a year for a .com domain and I’m using them to manage mine anyway, so should have just switched to them as domain registrar.
I’m on a very old Google Workspace package (for all mail) that they’ve never charged me for…and don’t seem to want to either, so I’m happy 😀
