Hi, normally after sending a meter reading you get an email within about 4 days and a new bill appears on your online account. If you see nothing after a week send the readings again. 

@gertom I don't know if this info is of any use to you: I have standard meters, not smart meters so I enter my readings manually, monthly. About 18 months ago I went to put the figures online as I have done for years and the screen said one of the previous entries (gas) was HIGHER than the reading I was about to enter. The system would not let enter the new reading because, of course, it was LOWER than the one it already had. I contacted SP (in those days they actually answered the phone) thinking my account had been compromised and they manually corrected the figures for me. It hasn't happened again.

Upshot is:- the online figures on customer online accounts CAN be manually changed by SP and they CAN be corrupted in some way. I am certain I had not entered an incorrect reading myself, so how had that incorrect reading gotten on to my account?

very frustrated withSP.  Have entered smart metre readings but unsure if they have been accepted!

.Have also tried unsuccessfully  over the last 4 months  to renew my current duel fuel tarrif.   Current tarriff runs out this month.  Have change it online 4 times,  had a quote, submitted and recieved achknolagement each time  from SP: however it has not changed in my account.  Am still on original tarrif. Aghhhh.

SP not contactable by phone Aghhhh.  Their chat line out of action, Aghhhh.  No way to contact them by email. aghhhh

NOT GOOD.

Hi sonwat, your new tariff will start when the old one expires. This gives you lower costs because all the new tariffs are more expensive and you need to use the full amount of the old tariff.
