Smart Meter Scams
Fraudsters posing as meter engineers to gain entry, steal data, or charge fees for free government schemes.
Last reviewed: 1 June 2026
What this scam is
Smart meter scams involve fraudsters impersonating authorised engineers or energy company representatives to gain access to your home, charge fees for a government-sponsored scheme that is free, or steal personal and financial information under the guise of a meter upgrade appointment.
Smart meter rollouts are a genuine, ongoing government-backed programme in many countries. In the UK, for example, energy suppliers are required to offer smart meters to all domestic customers. The existence of a large-scale, publicly known installation programme — combined with the fact that most customers expect a genuine smart meter visit at some point — creates a ready-made cover story for fraudsters.
The risks are varied. A fee-charging scammer exploits the lack of public awareness that smart meter installation is free of charge. A doorstep data harvester uses the appointment context to request personal details, account numbers, or to photograph documentation left accessible in your home. An opportunistic burglar uses the 'engineer' persona to gain entry and assess or steal valuables. Some operate in pairs, with one engaging you in conversation at the door while the other accesses another part of the property.
The scam also exists in digital form: phishing emails and texts claiming you have a scheduled smart meter appointment or that your meter requires a remote software update, directing you to confirm account details or click a link.
How it works
In the in-person variant, someone arrives at your door with a high-visibility vest, a clipboard, and possibly a vehicle with unofficial but convincing branding. They state they have an appointment — or that all homes in the area are being upgraded — and need access to your meter and potentially to the interior of your property.
Once inside, a fee-demanding scammer will tell you there is a charge for the installation, for a 'registration fee', or for an 'advanced model' that is not covered by the standard rollout. They may insist this is a one-off charge and that you should pay now before the slot is lost.
In the data-gathering variant, the 'engineer' may ask you to confirm your account details, show your energy bill, sign a form, or provide a bank account number for 'billing purposes'. None of these are things a genuine smart meter engineer needs to do — installation engineers are authorised by your supplier, the work is already attached to your account, and no payment is required.
In the premises-survey variant, the 'engineer' uses the appointment to walk through areas of your home, assessing or stealing items of value while maintaining a professional demeanour.
The phishing variant arrives as an email or SMS claiming a smart meter appointment has been made for your address and asking you to confirm or rearrange via a link. The link leads to a fake supplier login page that harvests your credentials.
Why this scam works
Smart meter installation is a legitimate, widely publicised programme, so an unexpected visit or contact claiming to relate to it is more credible than a cold-contact scam with no familiar context. People who have been anticipating their smart meter upgrade are particularly likely to accept an arriving 'engineer' as genuine.
High-visibility clothing, a clipboard, and official-looking documentation create strong visual authority. The uniform signals professional legitimacy in a way that ordinary clothing does not, and most people are not accustomed to challenging someone who presents in this way at their door.
The free-scheme context also makes the request to enter your home feel reasonable. You are not being asked to buy something — you are being offered something. This lowers the guard that a straightforward sales approach might raise.
A typical pattern
A householder is approached by someone in a high-visibility jacket who says they are from an approved metering company and have come to install a smart meter. The householder is not certain whether they booked this but knows smart meters are being rolled out. The visitor asks to be let in and, once inside, explains that the standard installation is free but that a newer model with better connectivity is available for a small additional charge. They ask for payment before proceeding. The householder pays. The 'engineer' completes a superficial inspection and leaves. Later, the householder discovers from their actual supplier that no appointment was ever booked and that smart meters are always installed free of charge.
Common red flags
- Unexpected visit from someone claiming to install a smart meter with no prior booking confirmation
- Request for payment for installation — the national rollout is free of charge
- Visitor who wants to move through your home beyond where the meter is located
- Caller or visitor who asks for your account number, bank details, or bill information
- Identity document that cannot be verified by calling your supplier
- Visitor who becomes impatient or pushy when asked to wait while you call the supplier
- Email or text with a link to confirm or rearrange an appointment you did not make
- Two visitors where one is keen to move into another area of the home

- Data-gathering variant — engineer uses the visit to collect account or personal details
- Premises-survey burglary — entry is used to assess or steal valuables
- Phishing email — fake appointment confirmation with a malicious link
- SMS smishing — text claiming mandatory upgrade with a link to a fake login page
- Paired visit — two people where one distracts while the other accesses the property
How to verify before you act
Call your energy supplier on the number printed on your bill to verify whether an engineer appointment is scheduled for your address. A genuine installation will be booked through your supplier and will be on record. If no appointment was scheduled, the caller is not authorised.
Ask any caller at your door to show you their official ID card — a legitimate engineer will carry one issued by the energy company or the metering firm contracted by your supplier. Note the company name and call your supplier to confirm they use that contractor.
Do not let anyone into your home while you are verifying their identity. A genuine engineer will wait; a scammer may become impatient or aggressive. You are entitled to check before granting entry.
Remember that smart meter installation is free under the national rollout. No authorised engineer will ask you for payment of any kind at the door or during the visit.
For digital contacts about smart meter appointments, do not use any link in the message — log into your energy account directly to check whether any appointment is scheduled.

Frequently asked questions
Is smart meter installation always free?
Under national rollout programmes, smart meter installation is free of charge to domestic customers. No authorised installer will charge you for the installation itself. Any fee request is a red flag.
How do I know if a meter engineer is genuine?
Call your energy supplier on the number from your bill and ask whether an engineer appointment is booked for your address. Also ask them to confirm which contractor they use for installations. Check the visitor's ID against this information before letting them in.
Can I refuse a smart meter?
Yes. Suppliers are required to offer smart meters, but acceptance is not compulsory in most jurisdictions. You can decline or defer an upgrade. This also means an unsolicited 'mandatory upgrade' visit that you did not book is suspicious.
What information does a genuine meter installer need from me?
An authorised installer needs access to your meter and any associated switchgear. They do not need your bank details, account numbers, or energy bills — this information is already on record with your supplier.
What if I feel unsafe with someone claiming to be an engineer?
You are always entitled to refuse entry and close the door. If someone is aggressive or does not leave when asked, call the police. No legitimate engineer will pressure you into letting them in.
I received a text about a smart meter appointment — is it real?
Check by logging into your energy account directly or calling your supplier. Do not use any link in the text. Your supplier should have your appointment on record if it is genuine.
Could a scam visit result in a burglary as well as financial fraud?
In some cases, yes. Fraudsters who gain entry under a false professional pretence may assess valuables, return later, or have an accomplice act while you are occupied with the visitor. Verifying identity before entry is important for both fraud prevention and physical security.
