Useful site yes but the OS grid references aren't fully accurate. I would say the 10 point grid references are out by 100m at a 280 degree heading so be careful if you are using for an accurate point. This has certainly wasted some of my time today!

Why did the British invent yet another grid reference system? Lat Lon is the standard, use it.

brilliant site, of great help, one suggestion would be to include satellite / hybrid views as often when zooming in to certain areas there are no visible landmarks to identify
