Have I been paying my landlords power bills?

Hi there,

I think I may have been paying my Landords Utilities for Two Tears

I rent a property where the owner of the property lives in a granny flat at the rear.  When I moved in he told me he has separate meters for utilities eg: gas, electric and Water.

My power was cut of the other day as my direct debit failed, but I noticed so was my landlords power.  I payed the bill and the power was re-connected.  I checked to see if there were any other meters around his granny and i found one Electric meter box.    However when I switched all the power switches to my property off, the power also went off in his granny flat.  So Im pretty sure his power is going through MY meter box.  I then checked to see if he had a separate gas or water meter, I found none.  Ive been living here for two years and in retrospect I can honestly say I have never seen a power bill arrive in his name.  I think ive been paying the whole lot…. gas electric and water.

What should I do?
