I live in a 3 bed semi and have for the last 15 years. Recently switched to ovo and then had the smart meters installed .
My usage has crept up over the years like everyone's. 


Now on OVO with smart meters and nothing has changed in my home  my monthly usage/direct debit has gone to £246 a month that's a second mortgage any ideas why my bills have double since i switched to ovo?

Having a smart meter installed won't directly increase your costs. There are no hidden effects on usage, and your tariff won't change. There are two things that will change after getting a smart meter though:

 

Your bills will no longer be estimated

 

If you hadn't provided regular reading previously then your bills may have been under-estimated. As we’ll receive a final reading from the old meter when this is removed this could generate a larger than expected bill around the time your smart meters are installed. The good news is that now we’ll be receiving regular readings sent automatically from your meter when we need it you can be sure your bill is spot on. This avoids any nasty bill surprises in future. 

 

On the other hand, if the final reading from the old meter taken by our engineer is under what we’ve been estimating, then we’ll credit the difference to your account.

 

Your meter will be accurate

 

The meter will clock accurately. Old meters can slow down, or even speed up meaning they're not measuring your energy usage correctly. We'd only expect to see this with very old meters. A brand new meter, smart or otherwise, will clock what you're using accurately. 

 

If you’ve got solar panels installed, a smart meter will ensure that any excess energy generated by the panels doesn’t make your meter clock backwards. This was a commonly seen problem with older traditional electricity meters.

 

It might be worth considering what else could have caused the increase to your monthly direct debit:

 

Plan prices may have changed over time


Another thing to consider is, if you've renewed onto a new plan recently, the unit rates and standing charges will have changed. You can check your unit rates and daily standing charges in the ‘Plan’ tab of your online account or OVO app (download for Android or iOS).

 

 

Your Direct Debit calculations are not only based on your current usage

 

If you notice an increase to your suggested Direct Debit amount after having a smart meter installed, it’s worth bearing in mind other things we check when calculating your recommended Direct Debit. We consider your average monthly usage and also the current balance, plus the length left on your contract. The Direct Debit will need to be increased if you have an outstanding balance or are coming to the end of your contract.

 

Is there any support available if I’m struggling to pay for my energy?

 

There’s help available if you’re struggling to pay your energy bills from us here at OVO, from government schemes and charities as well.  There are many ways we can help – such as setting up a payment plan for you, which spreads the cost of your energy to make it more manageable. If you want to find out about payment plans, you can request one online here. We’ll take you through what you need to do, and ask you for some details.

 

Our dedicated team is also specially trained to support you. They can make sure you’re receiving any financial assistance from the government that you’re eligible for, and take you through payment support schemes that are available. 

 

You can find out more about these schemes and where to seek free, independent advice right here.

I thin that summarises OVO - https://utilityweek.co.uk/ovo-tops-ukrn-list-for-complaints/

Ovo Energy received more complaints per 100,000 customers than any other supplier in the energy sector’s latest scorecard by the UK Regulators Networks (UKRN).

Beginning last year, UKRN publishes annual scorecards for four sectors: Energy, water, telecoms and finance.

The scorecards examine key consumer metrics covering service quality, price differentials and satisfaction levels.

Information in the scorecard for energy was collected by Ofgem in Q3 and Q4 2020 and compared to the same time in 2019, the total volume of complaints received by suppliers decreased.

Topping the list with 2,293 complaints per 100,000 in Q3 is Ovo Energy, which also includes the customers of SSE which it acquired in January last year, as well as those of Boost and Spark Energy.

Having posted on this forum for a few months this is what i have observed rather than anything scientific. So it may not be completely accurate. 

OVO appear to have had more issues than they would have liked migrating customers from SSE to OVO. Most migrations have been fine, but too many have had issues, some have been slow to resolve it appears.

Also I wonder if OVO is careful enough on following up on issues generally raised by customers, particularly whether they are quick enough and whether they keep customers informed. It may be more issues result in complains as customers get rightly frustrated. 

Review sites aren't a perfect proxy but OVO doesn't do bad in customer feedback although obviously there are some unhappy customers. This is a comparison of OVO vs Scottish Power for example.

Overall i have been very happy with OVO, albeit they are not perfect. But obviously some customers have had bigger issues.

This is not about customer satisfaction but about billing and something is definitely going on with their meters - like many others in this forum my problem started as soon as smart metre was installed. We can’t all be wrong and OVO right.

Please check out the thread below. I just found that my old meter was not deleted from records after the smart meter was installed, so my suplier thought I had two meters and was overcharging me. To be fair this was more the fault of the previous supplier who arranged for the smart meter to be installed, but regardless it was not easy to gather all the information and needed support from “experts” to identify the cause and convince the current supplier to probe deeper and confirm it was actually a problem and wipe a large amount from my bills.

 

I am now hoping to spread the word about this to pay forward the help I received from forum members!

The new meter was installed on Dec 13th, 2024 and suddenly the bills have drastically increased. While previously, I was paying like £60-70 per month on average, I am being charged like £5-6 pounds per day now, without any significant change in my energy usage. I have paid the bills two days ago and the balance was zero. Now, after just two days, it increased to £11.7! I really do not understand what is going on and opened a complaint. I was wondering whether anyone else has the same issue.

Hi ​@sfmoosavian ,

Just curious but was the previous meter a Smart Meter, and if not did you submit regular meter readings?

If you could also tell us things like your usage patterns, your tariff and what sort of heating/hot water you’ve got, we may be able to help figure this out. Forum Volunteers such as myself can’t access your account, so we can only see what you’re able to tell us.

Hi ​@Blastoise186 Thank you for the comment.

As far as I know, the previous one was not a smart one. I have rented this place and moved in four months ago but I was told by OVO that the meter needs to be replaced.

My issue is that nothing has changed on my end regarding the energy usage hence this sudden increase in bills does not make sense to me.

 

There is a heater in the unit, electric shower, and also water heater.

Here is the energy plan.


Unfortunately, I cannot see what it was. Also, the usage graph is not available

I am not sure if these are all you are looking for.

I assume that you are reading that £11.7! either from your In Home Display or from your online ‘live’ billing?

EDIT - we cross posted, you can’t see the online billing so it must be the IHD.

The figures shown on the IHD are just an indication, and may not be accurate.
In particular the money amounts will depend on what tariff the meter and IHD are showing, which may not be your actual tariff as it currently stands.

The online ‘Live’ billing is also just a daily indication and can be inaccurate for a few reasons.
eg. If the smart meter isn’t connecting, or only sending readings weekly or monthly then OVO haven’t got the data from it yet so the daily ‘usage’ will simply be estimated.

In the end both the IHD and the ‘Live’ billing can be useful, but also sometimes can be out and so confusing.

They don’t really matter though for what you pay - that is based on the meter readings at the start and end of your monthly billing periods.

As an example I had a new gas meter fitted in mid November, it’s only sending monthly readings (must contact customer support and get that changed).
I also havent had any gas usage charges applied to my bills since the change, not even estimates, so I know that my ‘live’ billing is currently too low a figure and will need to be caught up later. (I’m not too bothered because I know my DD amount is covering it and building up credit).

PS. My IHD also shows the wrong tariff and always has done, again support can correct that pretty easily if I ask. I havent bothered up to now because I read the kWh and not the £s.

I said, Hey - Watts going on.
