Energy company scam calls spike whenever UK consumer-energy policy makes the news — new price cap, government rebate, smart-meter rollout, tariff switch deadline. The script always converts the news headline into a fake refund or fake mandatory action. Whether you searched for energy company scam call, energy scam call uk, british gas scam call or smart meter scam call, this is the right page.

Script 1 — the energy-refund scam

Always tracks the news. After every Ofgem price-cap announcement or government cost-of-living payment, the calls multiply:

Good morning, this is [British Gas / Octopus / EDF / Bulb / Shell Energy] customer services. Following the latest Ofgem ruling, you are owed a refund of £247.50 on your account. To process the credit, please confirm your sort code and account number.
Common UK energy refund scam script (paraphrased)

Why it's a scam: real energy refunds are credited automatically to the bank account on file (typically the one your direct debit comes from). Real suppliers never collect sort code / account by phone — they already have it.

Script 2 — the smart-meter 'mandatory upgrade' scam

Targets older customers and people uncertain about the smart-meter rollout:

Your supplier is required to install a smart meter at your property by [date]. Please confirm your details and arrange an installation slot to avoid a £500 non-compliance fee.
Common UK smart-meter scam script (paraphrased)

Why it's a scam: there is no fine for not having a smart meter. The smart-meter rollout is supplier-led and voluntary on a per-property basis. No supplier installs via cold call — they invite you via your online account or app.

Script 3 — the tariff-renewal / better-deal scam

Sometimes a real outbound call from a switching affiliate (annoying but legal); often a setup for an account takeover. Asks you to confirm your address, your existing tariff, and 'transfer your account' to a new fixed deal.

Real switching always happens through your own choice on a comparison site or the new supplier's own portal — never as a cold-call commitment over the phone.

Script 4 — the warm-home-discount / government-rebate scam

Pretexts whichever government scheme is current ('Warm Home Discount', 'Energy Bills Support Scheme', 'Cost of Living Payment'). Asks for bank details to 'release the rebate'. Real schemes apply automatically; they don't phone you for bank details.

Suspected meter faultTheir engineer rings on the day to confirm access, never asks for payment

How to verify an energy-company caller

  1. Don't engage on the caller's terms

    If anything feels off, don't ask the caller to 'prove' their identity — they're scripted to do exactly that. Just hang up.

  2. Find the supplier's real number

    On a recent bill (paper or PDF) or on their official website typed into the browser yourself. Don't use the number that called you and don't use a number the caller gives you.

  3. Log into your online account first

    If there is genuinely an action needed, it will be flagged in the account. If nothing is flagged, the call was a scam.

  4. If you gave bank details, dial 159

    159 connects you straight to your bank's fraud team. Speed matters — most APP fraud is recoverable within the first hour.

Bottom line

Real UK energy suppliers don't cold-call about refunds, smart-meter mandates, or government rebates. The bills and the credits arrive on their own. If an energy-supplier call asks for bank details, payment or installation booking — hang up and verify via your online account or the supplier's published number. If you gave details, dial 159 and report to Action Fraud.

Frequently asked questions

Do UK energy suppliers cold-call about refunds?

No. Energy refunds (overpayment credits, government rebates, Warm Home Discount, Energy Bills Support Scheme) are credited automatically to the account on file. Suppliers never phone to ask for sort code or account number — they already have your bank details from your direct debit.

Is there a fine for not having a smart meter?

No. The UK smart-meter rollout is voluntary on a per-property basis. Suppliers offer installation via email and in-app; they don't cold-call about it and there's no penalty for declining. Any call threatening a fine for non-installation is a scam.

British Gas / Octopus / EDF called me — how do I know it's real?

Hang up and ring them back on the number printed on a recent bill (or on their official website typed into the address bar yourself). Real outbound calls are rare; the supplier will be able to pick up the conversation from your account record if the call was genuine.

What's the real Octopus Energy phone number?

Octopus Energy UK customer service is 0808 164 1088 (freephone), but Octopus is chat-first — most queries go via their website or app. Outbound calls from Octopus are very rare; cold calls claiming to be Octopus should be treated as suspicious.
