Can I refuse a smart meter?
A practical UK guide to your rights, what suppliers can (and can’t) insist on, and how refusing may affect tariffs, meter readings and support like prepayment and Priority Services.

We’re whole-of-market: the best option depends on your home, meter type, payment method and what’s available where you live.
Fast answer
Yes — you can refuse a smart meter in most UK homes, because installation is usually voluntary. However, your supplier may still need access for safety checks and may have the right to replace or upgrade a meter that is faulty, unsafe or at end-of-life. Refusing can also limit some tariffs and make meter readings your responsibility.
Key takeaways
- Voluntary in most cases: you normally can say no to a smart meter appointment.
- Not the same as refusing access: suppliers can still request access for inspections, repairs and safety.
- Tariff choice may be narrower: some deals may require a certain meter type (varies by supplier and region).
- Readings matter: if you keep a traditional meter, you may need to submit readings to avoid estimated bills.
If you’re unsure, do this first
- Ask what type of meter is being offered and why.
- Ask what happens if you decline (billing, readings, tariffs, appointments).
- Ask about Priority Services needs (health, accessibility, language).
- Get the plan in writing by email or letter where possible.
Your rights: when you can refuse (and when a supplier may insist)
For most households, accepting a smart meter is a choice. That said, suppliers and network operators still have duties around safety and accurate billing, and there are situations where some form of meter work may be necessary.
You can usually refuse when…
- It’s an optional upgrade and your current meter is working and safe.
- You’re not comfortable yet and want more information first.
- You want to keep a traditional meter and are prepared to provide readings.
A supplier may need to change a meter when…
- The meter is faulty, unsafe, damaged or suspected of being inaccurate.
- The meter has reached end-of-life and needs replacement for safety/accuracy.
- There’s evidence of tampering or a safety issue that requires investigation.
In these cases, you may still be able to discuss options (timing, accessibility needs, where equipment is placed), but refusing all access can escalate the issue.
Refusing a smart meter vs refusing access
- Refusing a smart meter
- You decline an installation appointment or ask to keep your current meter type (where safe/possible). You can still cooperate with readings and safety visits.
- Refusing access
- You prevent reasonable access for checks or essential work. This can lead to complaints, higher estimated bills, and in extreme cases court-warrant processes (used rarely and usually as a last resort).
If you’re renting
If you pay the bills, you’re usually the energy customer, so the decision often sits with you. But your tenancy agreement may have rules about allowing access for installations, and landlords may need to approve physical changes (for example, if equipment location changes).
If you’re not sure, ask the supplier what will be installed and whether any drilling or cabinet work is expected, then check with your landlord/agent.
Your options if you don’t want a smart meter
If you’re uncomfortable with a smart meter right now, you can normally keep your existing meter — but it helps to be clear and practical so billing stays accurate.
Option A: Decline the appointment (and keep giving readings)
- Tell your supplier you’re declining the smart meter installation for now.
- Submit meter readings regularly (for both gas and electricity if you have both).
- Keep an eye on bills for estimates and query any that look wrong.
Option B: Ask what the alternatives are
If the supplier says a meter needs replacing, ask what non-smart options exist and why. Sometimes a replacement is necessary, but the exact specification can depend on safety, availability and technical constraints.
Option C: Consider switching — but check meter requirements
Some deals may be available only with certain meter types (for example, some time-based products). Availability changes frequently and can vary by region and property setup. Comparing whole-of-market options is often the quickest way to see what’s realistically available for your postcode.
Two realistic scenarios (with numbers)
Scenario 1: Refuse smart meter, give regular readings
A household submits readings monthly. Over 12 months, their bills are based on actual use rather than estimates.
- Time cost: around 3–5 minutes per month to take and submit readings (estimated).
- Billing risk: low, as long as readings are consistent and clear (e.g., correct meter register).
- Tariff choice: could be slightly narrower if some products require a smart meter (varies).
Assumptions: traditional meter remains safe and supported; supplier accepts customer readings via app/online/phone.
Scenario 2: Refuse smart meter, don’t give readings
A household doesn’t submit readings for 9 months. Bills are estimated, then corrected when an actual reading is taken.
- Admin impact: can lead to a larger adjustment later (a “catch-up” bill or credit).
- Budgeting risk: higher — you may pay too little (then owe more) or too much (then wait for a refund).
- Support impact: if you’re on prepayment or need extra help, missing readings can make issues harder to spot early.
Assumptions: at least one actual read happens later (engineer visit, change of tenancy, or inspection).
Compare energy options (no pressure)
See what’s available for your postcode and payment preference. We’ll show options across the market, and you can decide whether smart-meter-only deals matter to you.
What to say when you refuse (copy/paste)
“I’m not consenting to a smart meter installation at the moment. Please confirm in writing what will happen next, how I should submit meter readings, and whether any essential safety work is required.”
Smart meter vs traditional meter: what changes for you
This comparison focuses on household experience — readings, billing, and practical trade-offs. Supplier policies differ, so use it as a decision aid rather than a promise of what any specific supplier will offer.
| What to compare | If you keep a traditional meter | If you accept a smart meter |
|---|---|---|
| Meter readings | You usually need to submit readings to avoid estimates. | Readings are typically sent automatically, but connectivity can vary by home/location. |
| Billing accuracy | Accurate if you provide readings; otherwise bills may be estimated. | Often more accurate day-to-day, but still check bills and read dates. |
| Tariff availability | Some tariffs may not be available; depends on supplier and meter type. | May widen access to certain tariffs, particularly those that rely on usage data. |
| Prepayment experience | May use a key/card or a traditional prepay setup (varies). | Some smart prepay setups can be managed remotely or topped up digitally (varies). |
| Home changes | Less equipment; you keep what you have unless it needs replacing. | Engineer visit and in-home display may be provided; installation depends on your setup. |
Decision checklist: refusing often suits you if…
- You’re happy to submit readings (and keep records).
- You want to avoid any new equipment installation for now.
- You’d rather wait until you’ve clarified data preferences or household concerns.
- Your current meter is working well and you’ve had no billing issues.
Accepting may suit you if…
- You often forget readings and want fewer estimated bills.
- You’re interested in tariffs that may require a certain meter setup (availability varies).
- You want easier tracking of usage to help manage your budget.
- Your supplier says the current meter needs replacing for safety/accuracy reasons.
Costs, exclusions and common pitfalls
Refusing a smart meter is usually more about trade-offs than direct fees. Here are the issues we see most often when households try to opt out.
1) Estimated bills and “catch-up” adjustments
If you don’t provide readings, suppliers will estimate. When an actual reading arrives later, your account may be corrected up or down. That can make monthly budgeting harder.
2) Misunderstanding “smart” vs “needs replacement”
Suppliers may contact you because your meter is due a safety/accuracy replacement. Even if you refuse a smart meter, you may still need to allow access for essential work.
3) Limited access to certain tariffs
Some tariffs rely on more frequent meter data or specific metering setups. That doesn’t mean you can’t switch, but you may have fewer options to choose from.
Potential costs (what to expect)
- Smart meter installation: commonly offered without an upfront charge, but policies vary and your home may need additional work.
- Engineer visits: missed appointments can sometimes lead to charges (check your supplier’s terms).
- Meter replacement work: if a meter is unsafe/faulty, replacement is usually treated as essential maintenance.
Common pitfalls to avoid
- Refusing a smart meter but not agreeing a readings routine.
- Not asking whether the visit is an upgrade or an essential replacement.
- Assuming a smart meter always works perfectly everywhere — connectivity can be affected by location and building type.
- Ignoring letters about access; if there’s a safety issue, keep communication open.
FAQs
Can my energy supplier force me to have a smart meter?
In most cases, no — smart meter installations are usually voluntary. But if your existing meter is faulty, unsafe or needs replacing for essential reasons, your supplier may require access to change the meter (which could be a smart meter depending on what’s appropriate and available).
Will refusing a smart meter stop me switching supplier?
Usually not. You can typically switch with a traditional meter, but some tariffs may require certain metering arrangements. The simplest way to check is to compare deals for your postcode and filter based on what you’re willing to accept.
If I refuse a smart meter, do I have to submit meter readings?
You don’t legally have to, but it’s strongly recommended. Without regular readings your supplier will estimate your usage, which can lead to inaccurate bills and a bigger correction later when an actual reading is taken.
Can I ask for a smart meter to be removed later?
You can ask, but removal isn’t guaranteed and depends on safety, practicality and supplier policy. If your concern is data or communications, ask first about settings and what options exist for how readings are used and shared.
Does refusing a smart meter affect prepayment meters?
It can. Some households find smart prepayment more convenient, while others prefer a traditional setup. If you’re on (or moving to) prepayment, ask your supplier how top-ups, emergency credit and support work with your current meter type.
What if my supplier keeps contacting me about a smart meter?
Ask them to clarify whether it’s a marketing-led upgrade or an essential meter replacement. If you’re refusing, request confirmation of how to provide readings and how they’ll bill you. If you feel pressured or treated unfairly, Citizens Advice explains how to raise a complaint and escalate it if needed.
Are smart meters safe?
Smart meters must meet UK safety and technical standards, and installation should be carried out by a trained engineer following safety checks. If you have a specific concern (for example, medical equipment or accessibility needs), tell your supplier and ask for an explanation of the safety process and any available adjustments.
Do smart meters work everywhere in Great Britain?
Not always perfectly. Some homes can have weaker signal or technical constraints, so smart functions may be limited in certain areas or building types. If you’re concerned, ask what happens if the meter can’t communicate reliably and how your bills will be handled.

How we assess “can I refuse a smart meter?”
We built this guide by separating three things people often mix together:
- Consent for an upgrade (usually optional).
- Supplier rights to access for safety/maintenance and accurate metering.
- Practical outcomes for households: readings, billing, tariffs, and support.
Limitations: Supplier policies and technical feasibility vary by property, meter type, and region. This page doesn’t replace your supplier’s terms or individual advice for complex installations.
