In several ways.
1) many forms of electricity theft rely on the removal and later replacement of the service fuse, after some illegal alteration has been made. A smart meter will detect and report this.
2) a smart meter records the PATTERN of electricity use rather than just the total consumption. No comsumption registering whatsoever for say 2 weeks at a time would be cause for investigation.
No consumption for an extended period does not not of course PROVE dishonesty, the customer might have gone on holiday and turned the power off, but it would probably warrent some investigation.
3) a smart meter can be accessed remotely, perhaps by an inspector sitting outside the metered property in a van with a laptop. If the lights are on but no, or improbably low consumption is shown, that would be grounds for investigation.
Lighting without mains electricity consumption does not PROVE dishonesty, the customer might be useing a generator, a battery bank, or oil lamps, but it would be grounds for investigation.
4) Examination of the "load profile", and knowledge of any recent heavy loading appliance purchases might also prove interesting. If someone has purchased an electric shower, but the load profile shows no corresponding consumption, that might warrant investigation as to whether the shower has been connected ahead of the meter. Again the data from the smart meter does not PROVE dishonesty, the shower might have been purchased for somone else, or might be stored rather than installed, but it would hilight "high risk customers"
