Finding Grid References for Maps

To find the OS National Grid Ref use wheresthepath, and either  use control key with mouse wheel to find your point of interest or click the Binoculars Icon to Enter a Place name, then click the finger pointing hand to give the NGR.

Another way is to use freemaptools but this system is not to accurate as uses the WGS84 co-ordinate system, whereas we should be using  OSGB36 co-ordinate system.

MagicMap is another good mapping tool with many different mapping options and overlays.
