Thanks for the reply.
Yes £65.99 on each house. About 20 years ago the householder of the property hosting the amplifier arranged for the rest of us to be recharged, at that time the charge was about a couple of quid each , with no admin fee, so I thought it only fair.
I don't have a problem with paying for the energy, it is the admin charge that has been introduced in the last two years that I am unwilling to pay. Particularly, as you point out, that there is no metering.
Yes I think an aerial is the solution if I can't get them to credit the admin fee.
Reason for the post was for advice on how to approach the problem with Npower.
Many thanks
