So smart metere are meant to be easier and send readings for you for accurate bills.

So looking through my parents bills, they have it quarterly.  So looking through the readings are estimated, why? It says "This bill - estimated" and [E] next to the reading numbers.

Ok - time to work out why the smart meter might not be sending readings then.

it’s probably worth trying to work out how long they’ve been getting estimates for too, as that might give a clue to whether it is something like an earlier SM which went dumb on supplier change or something else.

also, make sure they are supplying monthly readings from now so their bills are correct.

Electric

Looking at the IHD, the reading is the same as the meter itself.

Will give the app a go too.

The smart meter might be transmitting the readings monthly but not exactly when the bill is generated. This means that the reading they use when the bill is generated is still an estimate but only between the days the reading went in and the date of the bill.

Do the readings still roughly match what's on the bill?

That isn’t quite true. Smart meters transmit nothing. The comms hub acts like a mobile phone. It is connected to the DCC Network waiting for a call. Depending on the agreed reading profile, the supplier’s system will send out an instruction to the comms hub to ‘pull’ data from the meters. As I understand it, the response will contain up to 4 index readings per meter and XML files containing usage data.

If an estimate has been used, this may be down to a temporary connectivity issue. That is, the supplier sent an instruction to retrieve data and got no response. Clearly, for those consumers on a 30 minute profile where data is pulled once every 24 hours, this isn’t an issue. The supplier estimates against the previous day’s smart reading or it waits until one is received the following day.
