how to change google back to UK google from German google?

[pbandj]

had a German visitor, google box on toolbar brings up german results now instead of UK ones
help
thank you

Is there a Spanner icon on the toolbar (I use Chrome and it is on the far Right hand side) - click the spanner for the settings menu.

From the General tab, select a country domain (.co.UK) from the Use Google Site dropdown list.

In some versions of Toolbar, select General, then select language.
