Around all high voltage lines the air is somewhat ionized and this
may result in sufficient free electrons to seriously mess up the
GPS signal, although I wouldn't expect much trouble from a 11kV
line.
The fact that the navigation message is 50Hz in the GPS signal and
the power-grid in the UK is "close to 50Hz" is not a good thing
in any case.

Never attribute to malice what can adequately be explained by incompetence.
