The United States was invaded by Britain, in the War of 1812 and they burnt Washington D.C. and the White House (The U.S. had actually invaded Canada first and lost)
To be fair "invading" is a relative concept. If a country declares war on you, you do tend to visit their neighborhood and fuck their shit up.
Other times (like my country), Great Britain was invited to step in, to kick out the invaders. Also, pretty sure Great Britain also invaded countries which no longer exist... ;)
