Top 20 most influential BRITISH rock bands

Following on from the top American bands thread, it got me thinking about the influence of British bands on the rock genre, particularly in the early years. I'm specifically talking about classic/melodic/heavy rock bands. Here's my starting list, in no particular order:-
Black Sabbath
Bad Company/Paul Rodgers
Deep Purple
Free
Pink Floyd
Queen
Def Leppard
Cream
Fleetwood Mac (although it took two Americans to bring the band into the mainstream)
Whitesnake
The Who
Led Zeppelin
UFO
Rolling Stones
The Police
Rainbow
Thin Lizzy
Iron Maiden
Genesis
Judas Priest
Mott the Hoople/Ian Hunter
These are bands who not only achieved commercial success but heavily influenced their peers and often shaped the music that came after them.
I'm sure I've missed one or two, and I almost put AC/DC in there as they are almost British (The Young brothers were born in Scotland and they are now fronted by a Geordie)
Any more suggestions?
