A former Grantham man now living in the north-east admitted using electricity without authority and possession of cannabis.
Both of the charges relate to when Matthew Templeton, now of Rutland Street, Seaham, was living in Alexandra Road, Grantham.
However, despite the guilty pleas, Templeton faces a Newton Hearing as the prosecution and defence disagree about the amount of electricity used. The prosecution says £1,245 worth of electricity was used but Templeton denies it was that much.
The court heard Templeton could be made to pay for the damage to an electricity meter which he bypassed to make a gain. The hearing will be held on April 26. Templeton told the court he expects to return to live in the Grantham area soon.
