Big discrepancy between the usage graphs and the actual meter readings

No we have a combi boiler that has been on same setting since we moved in. Its very frustrating and obviously very concerning due to the massive cost increase 😑 

In that case, any suggestions I have descends to asking whether a slow cooker has been left on etc. 13 kWh limits the potential suspect appliances. … chargers for heavy duty tools, a powerful computer/games console on 24/7,  a large electric blanket, heated towel rail etc

If everything else can be ruled out and it is a 24 hours of the day problem, then I’d start to suspect a compressor, thermostat or seal issue with a fridge/freezer.

Do you have an in-home display? Can you see if the overnight load is also high? 

@Loubielou can you post the daily usage with 30min readings?

So we can see if the increase is at any particular time of day?

If you don't yet have 30min readings setup ask  OVO to do this. 

No slow cooker, all appliances have been the same since we moved in. Readings are actuals from smart meter and not estimates. No in home display as we didn't even know it was a smart meter until we saw that readings had been taken, previous occupier left no details etc. I've requested a monitor or an engineer to check because it is genuinely baffling. I spoke to ovo on chat on 31st and they've said they can swap to half hourly readings but this doesn't seem to have happened yet as on app it's only daily, and monthly usage I can see.

It can take up to five working days for changes to those settings to go through and data to start flowing, so we might need to come back to this thread later in the week.

My issue is the sudden jump in usage for no apparent reason. I need an display so I can turn everything off and see what happens to the usage. Half hourly readings will provide data but I want to suddenly get to the bottom of why overnight on a random December day did our usage almost triple????

While you wait for the half hour readings to be in place @Loubielou, it’s worth checking your plan .. I know you said you swapped mid Nov but look at the p per kWh charge as that could be another explanation for the sudden increase

That would be an explanation for an increase in cost, but we've had a very sudden increase in energy actually used, from around 7 to around 20. If usage had remained around 7 and cost had increased we would know it was cost per unit that had increased, but our usage units have increased for no apparent reason 

I’ve only seen your cost image data not kWh hence the suggestion 

I appreciate the suggestions, thank you, its just very frustrating as you can imagine!😫🙈
