Ordnance Survey (OS) make a number of datasets available free of charge under the terms of the current Open Government Licence (OGL). You are able to use the OS OpenData™ datasets in any way and for any purpose. OS simply ask that you acknowledge the copyright and the source of the data by including an attribution statement:

Where you use Code-Point Open® data you must add the following attribution statements:

If space allows it would be best practice to also include:

In each example please substitute the current year in place of ‘yyyy’

If you are displaying both OS OpenData™ AND OS Licensed Data then you should just use the appropriate OS Licensed Data attribution statement, there is no need to display the OS OpenData™ attribution statement as well.
