What smart meter refusal actually means
Your supplier has probably asked more than once. Maybe a letter, maybe a call, maybe someone on the phone sounding faintly disappointed that you’d rather keep your old meter. Smart meter refusal simply means saying no. That’s it.
You’re not being difficult, and you’re not breaking any contract. It’s your choice to make, and this guide covers exactly where that choice ends and where a supplier can override it.
Can my energy supplier force me to have a smart meter?
No, not in almost every case. Smart meters are optional for domestic customers, and a supplier can’t install one without your consent. If you’re the named account holder, the decision sits with you, not your landlord, and not a call centre script reading urgency into a routine upgrade.
That said, smart meter refusal isn’t unlimited. There are a handful of situations where your old meter gets swapped anyway, and it’s worth knowing them before a knock on the door catches you out.
When you can’t say no
If your existing meter is faulty, or it’s reached the end of its certified working life, your supplier can replace it. Their replacement stock is now almost entirely smart meters, so a broken traditional meter often becomes a smart one whether you’d planned for that or not.
The other exception is debt. If you’ve fallen behind on payments and a supplier gets a court warrant, they can force entry and fit a smart prepayment meter.
Who is protected from a forced prepayment meter
Ofgem’s rules put some households entirely out of bounds for an involuntary prepayment meter. It is worth being precise about these, because the thresholds are narrower than people assume and a near miss is not a protection.
Households that can never have one installed involuntarily
- Every occupant is aged 75 or over, and there is no other support in the household. A younger adult living there changes this.
- There is a child under 2 in the home. Older children do not trigger this protection on their own.
- Someone needs a continuous power supply for medical equipment, or has a severe health condition such as terminal illness, emphysema, chronic bronchitis or sickle cell disease, or depends on warmth for their health.
- Nobody in the household is physically or mentally able to top the meter up.
Beyond those categories, a supplier still cannot simply turn up. Before any involuntary installation they must make at least 10 attempts to contact you, carry out a site welfare visit, and record the visit on audio or body camera. You are also owed £30 credit per meter installed this way, and your debt has to be reassessed with a route back off prepayment once it is repaid.
If any of this applies to you, our guide to prepayment meter rights goes through the redress in more detail, and the Priority Services Register guide explains the extra protections that apply during any meter work.
Will refusing a smart meter cost me anything?
No, there’s no separate charge for saying no. You’ll stay on your existing meter and be billed the same way as before, using estimated or manually submitted readings.
What you might miss out on is convenience rather than cash: automatic readings, real time usage data, and eligibility for some time of use tariffs that need a smart meter to work. Treat smart meter refusal as a trade off, not a bill.
Ofgem’s 2026 rules if an installation does go ahead
From February 2026, Ofgem introduced new guaranteed standards covering smart meter installations, whether you asked for one or you’re in one of the exceptions above. You are paid £40 automatically, without having to claim, in any of these situations:
When £40 is owed
- You wait more than six weeks for an installation.
- The installation fails because of something the supplier got wrong.
- You report a problem and the supplier does not give you a resolution plan within five working days.
Roo would call that the world’s most politely worded fine. It exists because long waits and half finished installations were common enough that Ofgem decided suppliers needed a financial reason to get it right first time. A fourth standard, covering meters that are still not working in smart mode after 90 days, is due later in 2026.
Note that these are separate from the £30 credit owed on an involuntary prepayment meter installation. They are different rules for different situations, and it is possible to be owed under both. Our smart meter compensation guide walks through what you’re owed when a meter you already have goes wrong.
On the wider rollout: Ofgem’s binding installation targets framework ran from 1 January 2022 to 31 December 2025 and has now concluded, with government having published its decision on what replaces it. Over 70% of homes in Britain now have a smart or advanced meter, and more than 90% of those are working correctly. None of that obliges you personally to accept one.
How do I put my smart meter refusal in writing?
Tell your supplier in writing, or note it clearly on the phone and ask for confirmation by email. Keep that confirmation somewhere safe, since it’s your evidence if the same request lands again next year.
If installers still turn up uninvited, you can refuse them entry at the door, and that’s the end of it in almost every case. If letters keep coming after you’ve said no, a short follow up quoting your right to decline usually settles it. For everything else on your account, our smart meters for UK households guide covers what a working smart meter actually changes day to day.
Key takeaways
- Smart meter refusal is your right as the named account holder, and your landlord can’t override it.
- The main exceptions are a faulty or end of life meter, and a court warrant tied to unpaid debt.
- Some households can never have an involuntary prepayment meter, but the thresholds are specific: all occupants 75 or over with no other support, or a child under 2, or medical dependence on power, or nobody able to top up.
- If an installation goes ahead and goes wrong, £40 is paid automatically under Ofgem’s February 2026 standards.
- Put your refusal in writing and keep a record in case the same request comes round again.

Frequently asked questions about smart meter refusal
- Does smart meter refusal affect my ability to switch supplier?
- No. You can switch energy supplier with a traditional meter exactly as you would with a smart one, and refusal doesn’t limit which deals you’re offered on most tariffs.
- Can I change my mind after refusing a smart meter?
- Yes, you can ask for one to be installed at any point in the future, and your supplier has to arrange it under the same appointment rules, including the six week standard.
- How much compensation am I owed if an installation goes wrong?
- £40, paid automatically, if you wait more than six weeks, the installation fails through supplier error, or you report a problem and get no resolution plan within five working days. These standards took effect in February 2026.
- Am I protected from a forced prepayment meter if I have children?
- Only if a child in the household is under 2. That is the threshold Ofgem sets for the absolute protection, so older children do not trigger it on their own, although your circumstances may still be relevant to the welfare assessment the supplier has to carry out.
- Do I need a smart meter for a fixed energy tariff?
- No, most fixed tariffs work fine on a traditional meter. It’s mainly time of use and some smart export tariffs that require one.
- Will my bills be estimated forever if I refuse?
- Not if you submit your own readings regularly. A quick manual reading every month or two keeps your billing accurate without a smart meter.
Whatever you decide, the choice is genuinely yours. No follow up letter changes that. But if dodging the smart meter conversation got you thinking about your tariff too, that’s worth a second look while you’re at it.
