Just seen advert on TV saying British Gas are upgrading all their customers to smart meters to monitor usage on Power, Lighting, Heating etc,
Can anyone tell me how they work?
e.g. are they linked to consumer unit somehow? without ammeter's on each circuit how can they differentiate between power & lighting usage??
