Strange Sunday usage

Hi all,

First post here, so please be kind :sweat_smile:

We recently had a Smart Meter installed, and as such with any novelty, we have been watching our usage to see where our money is most being spent (with the hope that maybe we can cut down if possible). Our usage is typically high on a day-to-day basis, around £3 per day. We live in a 1 bedroom house, fully electric and have our Heaters run only during the Economy-7 hours of 01:30 - 07:30. Our water is also only heated during Economy-7 hours, so I’m not massively surprised when I wake up to see around £2 usage. However, every Sunday we see excessive usage, always in excess of £5, and we’ll typically wake up to see it more than our normal daily-spend.

As a test, when we went on holiday, we turned everything off except the fridge and freezer and monitored our usage remotely. Whilst we saw an immediate drop in our typical daily usage to around £1.50, the “Sunday Phenomenon” continues to happen, despite us not being there and nothing running except the Fridge and Freezer, we continued to spend in excess of £5.

Is Bulb doing something on a Sunday that would be causing this? Is perhaps a correction being made somewhere that we’re not being notified about? We have no Smart Routines running at all, so nothing extra is being triggered on a Sunday. If not Bulb, can anyone offer any suggestions as to what I might do to find out exactly what is causing the Sunday Phenomenon?


Hi @rotaru.madalina

Thanks for your post and welcome to community :wave:

I’ve just reached out to our smart team to have a look into this for you. My current thought is that maybe the IHD is updating with standing charges/ usage on a Sunday.

In the meantime, do you know if you are looking at your daily or weekly usage on the IHD?

Here is a useful guide on how to work your IHD.

Additionally, it looks like there is a billing issue on your account. This seems to have been caused by an incorrect changeover reading from your smart installation. I’ve dropped you an email asking for some information from you so we can look to get it sorted.

Hi Maddie,

I just created a post myself because when I was looking at my IHD yesterday evening, I saw that my IHD charged me 0.25p at midnight. So I started the Sunday with a charge coming out of nowhere.

With every switch killed in my flat, I woke up being charged 0.60p when my daily usage is 0.90p so I think something is going on Sunday, waiting for a reply myself.

can anyone tell me why the gas usage displayed in the dashboard is alternating with 17p and £1.19
This is obviously incorrect.

Mine does the same thing but it’s either 26p or 72p. The idiot I corresponded with at Bulb hasn’t got a clue what’s happening and says “the graph is just a guide and the monthly meter reading is what’s used to calculate my bill.”
Good luck with your enquiries, mine went nowhere.

Good afternoon guys,

Sorry to have merged your post @phil2990 but I thought they were both quite relevant discussing the strange usage coming through on your IHD.

I can only assume this is the standing charge, but i’m unsure why it has changed day to day.

As soon as I have an update, i’ll let you guys know

No, definitely not standing charge, it has been doing this for some time and does not relate to gas usage, it makes having a smart meter irrelevant

Hi @phil2990

Have you noticed a time pattern at all when these amounts show ?

Ele :bulb:

I am sure you can see my dash board. It used to be alternate days of one amount then another, always the same figures. Now it appears to be two days one figure then two days another. To be honest, it doesn’t bother me to much as long as I am being billed correctly, but why have a dashboard if it is not reading correctly?

Hi @phil2990

I’ve just spoken to a colleague who had experienced something similar.

The usage graphs only report whole units, meaning that if one day you used under, that usage would be reported the following day when the unit amount used was over one.

This means that some days your usage would seem to spike but really it was just from the day prior.


If the figures weren’t identical I might go along wit it, I do not have identical usages, if you don’t have an answer to this phenomenon don’t be afraid to say so but please don’t make it up

Just found this thread and the same has been happening with my IHD.
Cant say if it’s happening all the time as I don’t always check the IHD at 12am when getting ready for bed but have noticed like as others have posted it can say 25p at 12am.
