Neighbours electric meter alarm constantly going

As above, neighbours prepayment meter is outside and the alarm is always sounding. She can't even hear it in her house. It's constant on weekends. Her house is other side of the fence and behind mine (technically in another estate) but it's driving me insane. Can't go sit in the garden, can't have the windows open because the sodding meter is all I can hear. It's been going on for the last few months, and whilst I don't want to cause a confrontation or embarrass her. I know times are tough for most, but the noise is driving me mad. Is there a way to gently approach the fact or can I request NIE arrange to move the meter indoors?
