Yes. But what it really means is that you are from a bit SE or Orkney ...
which is England.

I should add: when FTDNA started their PF, the only academic
samples from the British Isles were Orkney (from the HGDP)and Ireland
(from a medical study, but available from Illumina).
However, very recently a good set of real English became available.
The result of using English instead of Orkney is that quite
a bit more people test as 100% English instead of say 90% English
and 10% something more eastern or southern.
