Are there any disadvantages to getting a smart meter?
Updated on 18/07/24 by Shads_OVO
Risks, dangers and downsides to smart meters?
You might have noticed we’re big smart meter fans here on the OVO online community. We really believe in the potential of this new in-home tech to make managing your energy account easier and to revolutionise the way our energy grid works. Don’t just take it from us - our community members have also shared their love for smart meters on a great SMETS 2 installation guideand alowdownon the inner workings of how smart meter firmware works.
As with all new technology, there’s been a few teething issues and user anxieties over how things work. In the interest of transparency we’ve collated some common smart meter concerns and attempted to address them - giving more OVO members the confidence to go smart!
Can you refuse to have a smart meter installed?
All energy suppliers have been tasked by thegovernmentto make sure their customers are offered a smart meter, however at the moment it’s up to you whether you decide to get one installed. We need to get permission from whoever pays the energy bills before booking an appointment and can’t enter your home to carry out the installation without your consent.
Ofgemhas made it clear that we must treat members fairly and any communications we send out about smart meters must be complete, accurate and not misleading. Whilst we can encourage you to go smart by offering you cheaper rates if you’ve got smart meters, we can’t force this change on you if you’re not ready yet.
Having said that, the law surrounding smart meters may change in future, to ensure that the smart meter rollout can achieve the coverage it needs to properly transform our energy grid. So we’d really recommend getting ahead of the game!
Are smart meters safe, don’t they give off radiation?
This is a big one - and we empathise with the safety concerns about having something new in your home. You might have heard that smart meters are radioactive - which is understandably worrying! That’s why we’re keen to reassure you of the stringent testing that smart meters have gone through.
Public Health England, an executive agency of the UK Department of Health, has collated various studies, reviews and assessments to measure the effect of smart meter radio waves. They’ve concluded that the radio waves produced by smart meters don’t pose any risk to your health.
In fact smart meters emit levels of radiation that are a million times less than the levels allowed by international guidelines. This is down to the fact that a smart meter is not in constant communication so only emits radiation when it is scheduled to send us a reading (which can be as little as once a month). This and the fact that the meters are generally much further from the body than other radio-emitting devices like mobile phones.
Do smart meters affect WIFI?
As smart meters use radio or mobile phone signals to communicate rather than your home’s WiFi, they won’t affect your internet connection or surfing speeds.
Can smart meters be hacked?
Another important worry to address. Given the smart meter tracks what you're using, there have been concerns raised that this information could be misused if it’s not stored and sent securely. That’s why smart meters are equipped with a security system developed by leading experts in industry and government including GCHQ’s National Cyber Security Centre, making the data encryption comparable to internet banking.
It’s worth mentioning that it’s only your usage information that’s stored or sent by the meters. No personal details, such as your name, address and bank account details are held here. We only store this type of information on internal systems which are strictly regulated in terms of Data protection legislation.
Can smart meters give wrong readings, can your bills be higher with a smart meter?
Smart meters are far more accurate and reliable than traditional meters and very rarely send wrong reading or clock too fast. If you’ve noticed a change to your usage since getting a smart meter installed it’s worth bearing in mind that if you hadn't provided regular readings previously then your bills may have been under-estimated and therefore appear to increase after a smart meter is installed. As a smart meter sends us a reading when we need it you can be sure your bill is spot on and avoid any nasty bill surprises in future.
Can smart meters really lower your bills?
Whilst getting a smart meter alone won’t necessarily lead to lower bills, the increased visibility of your usage can make you aware of ways you can reduce what you use and your energy charges as a result.
More than 80% of people with smart meters have taken steps to reduce their energy use and as a result, cut their bills. It is estimated smart meters took £300 million off consumer’s bills in 2020, rising to more than £1.2 billion per year by 2030 – an average annual saving of £47 per household.
Not only will you be able to keep an eye on what you’re using with a free In-Home Display we’ll also publish your smart meter usage data on the ‘usage’ pages of your online account or OVO app (download for Android or iOS). Having a smart meter also means you’ll get even more energy-saving tips with OVO Greenlight.
Can you switch with a smart meter?
Of course! Getting a smart meter installed doesn’t tie you to that particular supplier. In fact with the new SMETS2 meters being installed and the national upgrade of SMETS1 meters - the aim is that all smart meters will soon be cross compatible with all suppliers. Even if your smart meter isn’t currently compatible you’re still free to switch - you might just have to start taking your readings manually again until the meter is updated.
Will getting a smart meter mean you’ll be charged more for using energy at peak times?
Your current plan isn’t affected when your smart meter is first installed. You’ll be paying the same unit rates for your energy as you did before. Unless you’re already on one of our dual-rate plans, you’ll be charged the same amount whenever you’re using energy.
One of the benefits of smart meters is that we’re able to take meter readings automatically, and more regularly, as often as every half an hour. This means there’s the potential in future to offer a tariff which would offer your different rates at different times of the day, encouraging members to use more at times when the demand is lower. This is a great way of incentivising a more stable national energy demand and will help us to balance and de-carbonise the grid.
However these types of tariffs are very much in the ideas phase at the moment. We don’t have any immediate plans to introduce these at OVO and like all our fixed plans, they would be offered as an option rather than compulsory plan.
Heard any other smart meter stories you’d like us to take a look at?
Comment below with any concerns you might have - We’re keen to put any niggling doubts to rest!
OVO member but not got a smart meter yet? - Book today!
Smart meter lost communication with OVO? Fill in this Online Form.
What radio band does your smart meter use as 2g and 3g bands will be closed down in a few years.
GSM and GPRS. The GSM link will remain active regardless and there’s absolutely tons of time left anyway. Most meters will be dead before the 2G network is turned off.
-After 12 months energy companies can make you pay for faulty meters.
Nope. That’s IHDs, not the meters themselves. Faulty meters will always be replaced for free regardless of age.
Plans are to use the devices to charge households more to use power at peak times.
That’s opt-in only stuff. There’ll always be flat rate tariffs on offer which charge the same rate 24/7/365.
Those who fall into energy debt also risk their smart meters switched to prepayment mode.
And those without a Smart Meter will find that a supplier can just get a warrant to force entry and replace the meter anyway. Same hyper-strict rules apply for both i.e. absolute last resort ONLY. It’s not a default option.
If Ovo can’t take my readings correctly when I input them on the website, what reassurance does a smart meter give? Is the Internet going wrong? I have absolute faith Ovo will ensure they get their money in advance as the £2500 hike in my April bill shows.
While they still go through all the same checks, balances and validations, readings submitted directly by a Smart Meter are usually a little more trusted than those from a human, they’re less likely to get the numbers wrong!
Hey @nuru26,
OVO wouldn’t charge a customer to replace a faulty smart meter.
I believe what you are referring to is a ‘time of use’ tariff, customers would be incentivized to use energy at times where the grid is greenest by being charged less for this. As opposed to being charged more for using energy at peak times. You can find out more in the following topic:
The majority of suppliers have changed customers to pay as you go from pay monthly, this pre-dates smart meters. A customer who has a traditional meter and refuses to pay for their energy use may be served with a warrant and their meter changed to pay as you go. There are very strict guidelines in place, Tim has given a really helpful response on this:
As for the question regarding 2G and 3G, please check out this similar topic:
Hope this helps.
I am electro sensitive, no microwaves or wifi in our home for this reason. My current meter is only reading on the day dial and needs replacing. My current supplier is forcing a fully commissioned Smart Meter as the only option.. I am wondering if OVO would be able to take me on as a customer and install a dumb smart meter so I am not fried by the pulsing wifi comms of Smart Meters? Being around EMF affects my health so I have to make decisions that limit EMF smog and WIFI pollution
Hi,
This comment was left by a forum volunteer. We don’t work for OVO.
Sorry, but the answer is no. In actual fact, if you need Economy 7 then you’ll have to have the Smart Meter fully commissioned, otherwise E7 won’t work at all. The option to have Comms disabled likewise no longer exists.
I should also advise that there will still be tons of EMF near you regardless of whether or not you have a Smart Meter. Just about anything that uses electricity emits it. With all due respect, there is nowhere on the planet that’ll let you completely escape all EMF.
Please do not attempt to tamper with it by doing things like putting tin foil around the meter. You risk a nasty electrical shock or setting the entire house on fire and it goes without saying. Electricity and metal do not mix well. Oh, and those tactics don’t work anyway. The signal is strong enough to just penetrate through them and in some cases, the “blocker” only serves to amplify the signal and make it even stronger.
Also, the stocks of Traditional (i.e. non-Smart) Meters have basically dried up at this point and with the RTS Service shutting down sooner or later, your only upgrade path is Smart Meters.
We do not need E7 rather the broken meter is E7 . Thanks for the info re EMF, you will not be surprised that I am well aware of it !!! but to have this high pulsing EMF so close and without option of switching it off is a problem. .. I realise smart meter .. what a laugh with that ridiculous name… is the limited option, but simply want it set up as DUMB We have NO storage heaters or major energy items needing E7 and do not currently have an E7 tariff from our supplier .. I was told I could have it set up as a DUMB meter and now the supplier has back peddled on this
Hey @TLC2023,
@Blastoise186 has already given some helpful advice here, just wanted to add that most suppliers wouldn’t install a dumb meter. It’s smart meters that are now manufactured. If your meter needed to be exchanged with OVO, it would be for a smart meter.
Hi @TLC2023
You could have a chat with Citizen’s Advice. This is from their website.
Even if the extra functionality is switched off you would need to check what this actually means.
They may have some independent ideas about who to contact.
Do you have a doctors letter about your condition saying you can't have a smart meter?
Thanks so much for this.. They say get a Doctors letter but it is unclear what sorts of doctors they will recognise.. I am waiting to get this clarified.. So grateful for all of your help

I would have thought your NHS GP.
Can you provide that?
I would have thought a doctor would have to be on the GMC register as a minimum
Who has told you a smart meter will impact your health? Was it a GMC registered doctor?
As far as I’m aware, that CAB advice is possibly outdated. I can vouch for the claim that not many non-Smart/Traditional Meters are still manufactured. That’s true because there’s basically no demand for them and therefore, not worth making more. Likewise, the transition to Smart Meters means the vast majority of suppliers have depleted their remaining stocks of Traditional Meters down to zero. The only known exception is for very specific exotic meter types that currently have no Smart migration options. Those meters are however, reserved purely for people who need to have such a meter replaced due to a fault on a like for like basis.
For those on Traditional Prepayment Meters, your setup will remain supported as-is for the remaining life of the existing meter(s), but the next one after that will be Smart. OVO is still maintaining the engineer equipment used to access and maintain such meters and there remains a healthy supply of replacement top-up keys and cards in OVO’s inventory and that of other suppliers.
The situation is similar for those on Traditional Credit Meters. Your setup remains supported (unless you’re on RTS Meters) for the remaining life of the existing meter, but the next swap will make it Smart. There is no special equipment required to maintain these meters, nor a need for keys/cards.
It wouldn’t be the first time I’ve found CAB to be falling behind the times either...
It used to be possible to kill Comms/Smart features back in the SMETS1 days, but it caused nightmares because once disabled, it was impossible to re-enable them. And that meant if someone else moved in who wanted to have Smart/Comms features re-enabled, the only option was to replace the entire meter.
For that reason and a few others, the ability to shut down Smart/Comms features was eliminated from the SMETS2 spec at an early stage of development, in other words it was decided not to include it at all. Those features were never released into production and there are no S2 Comms Hubs, IHDs or Meters that can have Comms disabled.
From what I’ve heard, that functionality is also no longer available for SMETS1 sites that migrate to DCC via the Enrolment & Adoption.
Even if left non-commissioned, there’d still be activity on the ZigBee HAN/WAN anyway as the Comms Hub attempts to establish a connection to DCC pretty much as soon as it’s powered up and this cannot be disabled.
While I appreciate your concerns, I’m afraid I do not know of any alternatives anymore.
Thanks so much for this.. I just wish the suppliers had a consistent set of notes that they worked from .. every conversation seems to give different information. It is a sad time when our choices are eroded.. We are happy to pay for manual meter readers and truth is the system has worked beautifully for years without the need to have constant data flow because most IT systems are so deficient that they cannot even use the data that they do get !!
When it comes to OVO, passing on that feedback is a piece of cake. Leave that one with us as we can discuss it backstage with the forum moderators if needed.
Unfortunately however, we’re unable to reach out to other suppliers. I’d recommend the complaints process for that.

Who is your current supplier @TLC2023
My face and hands start burning around EMF.. I cannot use a iPad and have many other things that affect me with eyes burning too.. Doctors are not trained and do not recognise this as a condition and it is only very specialised private practitioners who would be knowledgeable enough to do so .. NHS doctors are pressured and incentivised not to be helpful if it conflicts with a government agenda for change ..

Hi @TLC2023
Can you post a website link to your specialised private practitioner who has diagnosed your condition?
I have not used mainstream medics as they are totally untrained in this field and have relied on non mainstream..

Hi @TLC2023
I am being careful just using your words to avoid any confusion. I hope that is helping?
Can you post the website link for the non mainstream specialised private practitioner who has diagnosed your condition for you?
You used these words in your last two posts? "Non mainstream" in one post and "specialised private practitioner" in the other.
I have not used any practitioners as I do not need a doctor to tell me that I have a reaction to being around EMF nor that it only started when a DECT handset malfunctioned and my whole body was microwaved .. At the time my GP would not support the idea that I had been burned even though I had was in pain with deep burning sensation through out my body . the only way I might be able to get the independent certificate would be via a private GP or a functional doctor.. I have not sought out support from anyone yet

Hi @TLC2023

You said in your previous post that you "have relied on non mainstream"
Can you provide a link to this in case it helps find a "private GP or a functional doctor"
Hey @TLC2023, I have a couple of questions and scientific evidence regarding some of your queries and concerns.
Smart Meters use non-ionising EMF signals to send meter readings from the meter to energy companies, which use Mobile Phone signals known as radiowaves. Under the umbrella of radiowaves you have AM Masts, TV, Radar, that’s even before you get into Infared waves caused by your regular in house TV Remote, I’m assuming you use a TV right?
This great image above shows the basic knowledge of harmless radiowaves to infared then ionising waves such as UV & x-ray as two example. Visible light (still harmless) would have more of effect than smart meters & microwaves. It’s entirely impossible to live within the UK and escape from EMFs, they’re all around us.
Now in accordance with electro sensitivity, there is no scientific evidence to support the medical condition of electro sensivity or EHS (Electromagnetic hypersensitivity), the WHO has a very detailed link d1] regarding this, unforetunately EHS is a self-reported condition that hasn't been proven by science, there is no scientific evidence to support the existence of EHS. The fact sheet from the WHO also states that the symptoms of EHS are not a consequence of EMF exposure.
More info on EHS: Electromagnetic hypersensitivity (EHS) is a condition where someone feels that they are extra-sensitive to electromagnetic fields (EMFs) and experiences symptoms like headaches and pain triggered by exposure to electronic devices. EHS is a self-reported condition that hasn't been proven by science. Recent research has found no evidence that EHS exists e2].
The Healthline link provides further empirical peer-reviewed studies as evidence of even a nocebo effect for EHS. o3]
I hope this further sheds light on any concerns you have regarding smart meters and low non-ionising EMF Radiation, which are very safe ,4} and cannot damage humans on a molecular level much like x-rays can.
Thank you for this science. Tge sane hone if science said smoking was good for pregnant women and thalidomide was safe. It said MMR vaccine was safe until it created so much harm in its early variety and was withdrawn and replaced. That scientists using their limited knowledge say it is safe and with the pressure to prove a commercial view does not prove anything Thank you for your thoughts and you express why this smart meter situation is such a huge risk. They are not seeking evidence of harm rather why they are right. Snd this creates a massive problem ffor me and thousands of others
MMR vaccines are highly safe - “A systematic review and meta-analysis of the benefits and risks of MCV1 in infants younger than 9 months found no differences in the risk of adverse events after MCV1 administration between infants younger than 9 months and those aged 9 months or older” - https://pubmed.ncbi.nlm.nih.gov/31548079/ - meta analysis studies are top of the evidence food chain.
Smart meters are highly safe and plenty of robust evidence to support this conclusion. Including evidence from my last post.
I am sorry but there is no supporting evidence to conclude EHS/electro sensitivity exists. There’s plenty of RCT controlled studies where participants have been in cohorts where 1 cohort had EMF emitting devices and the other had a placebo, there was little difference in knowing what was the EMF emitting device and what was placebo. These types are studies are publicly available to anyone.
In no means is my intention to be malicious or demeaning but making your condition is associated to something else?
Thank you.
This forum probably isn’t the best avenue to be trying to confirm or dispel medical theories. We’re not really set up for that here and none of the forum volunteers are qualified medical professionals so we can’t provide medical advice.
I definitely think the original question has value to the forum though and that is something we’re looking into. I will be the first to admit that researching or finding a solution to this edge case isn’t going to be easy, but we’ll see what we can do. It’s made more complicated because this is the first time anyone on this forum has asked this question.
There has been quite a bit of discussion backstage about this thread between the forum volunteers today, but most of that has been trying to figure out what the best options are to answer the original question. We’re still working on that in the background with a lot of head scratching as we really do want to try and figure this out. Please bear with us as this may take a few days and we may need to call on advice from some experts for their thoughts.
We thank you for your understanding.
I fully understand that and appreciate the words.
However, there’s a scientific consensus that concludes theres no scientific evidence for the conditions existence and could be the cause of another ailment or condition. Unless the consensus is updated with relevant studies going forward I believe the evidence is quite clear and we can use Occams Razor to get to the most simple conclusion being the right one.
As for myself I have a scientific background and hence my replies. Which I hope have been polite & sincere.
It it quite the good debate and glad these questions are being asked, as this is how we all develop knowledge and understanding.
Thank you.
