What Is H3G on My Bank Statement?
H3G is Hutchison 3G UK Limited, the registered company behind the Three mobile network. If it is on your statement, it is a Three bill — a mobile contract, SIM-only plan, mobile broadband, an add-on or a device payment.
Why it never looks familiar: you signed up with a brand, and you are billed by a company. Nothing on a Three bill, shop front or advert says "H3G". The abbreviation only ever appears on the banking side.

Who they are
Hutchison 3G UK Limited, company number 03885486, is the legal entity that operates the Three network in the UK. The name comes from Hutchison Whampoa, the group that launched the network, and 3G, the technology it launched on in 2003.
The brand has always been Three. The company has always been Hutchison 3G UK Limited. Only the second one reaches your bank.
What the charge will be
- A monthly mobile contract — airtime, or airtime plus a device plan.
- A SIM-only plan, usually a smaller monthly amount.
- Mobile broadband — a dongle, a MiFi device or a 5G home broadband router. These are a common source of forgotten payments, because the device sits in a drawer while the contract runs on.
- A device loan. Where the handset is financed separately, you may see two payments each month rather than one.
- Add-ons or out-of-bundle charges — extra data, roaming, or calls outside your allowance, which make the amount vary from month to month.
Why the amount changes
Two payments in one month usually means airtime and a device plan billed separately. A larger-than-usual bill usually means out-of-bundle usage — roaming is the most common cause, followed by calls to non-geographic numbers.
An unexpected increase at the same point each year is likely a contract price rise, which mobile providers apply annually under the terms of the agreement.
The mobile broadband trap
Worth calling out because it accounts for a lot of "I don't recognise this" cases.
Mobile broadband contracts — dongles, tablets, in-car wifi, backup routers — get set up, used briefly and forgotten, while the direct debit continues for the full contract term and often beyond. Unlike a phone, there is nothing in your pocket reminding you it exists.
If you have an H3G payment you cannot place and you do not have a Three phone, a dormant mobile broadband contract is the first thing to check.
Is it a scam?
No. Hutchison 3G UK Limited is the correct legal name for Three, and the descriptor is legitimate.
The usual caveat applies: the name being real does not make the payment yours. Mobile contracts are a known target for identity fraud, precisely because a contract can be opened online and the handset resold. If nobody in your household is with Three, that is worth pursuing rather than dismissing.
If nobody in your household is a Three customer
A mobile contract taken out in your name is a credit agreement, and it will appear on your credit file.
Check your credit report. It shows what has been opened, when, and what else was opened around the same time — which tells you whether this is a single fraudulent contract or part of a wider identity problem. You are not usually liable for credit taken out in your name by someone else.

How to check or stop it
Sign in to your Three account at three.co.uk or in the Three app to see the plan, the bill breakdown and when the contract ends.
Check the contract end date before cancelling. Stopping the direct debit does not end the agreement — you will still owe the remaining term, and missed payments are reported to credit reference agencies.
If the contract has ended, you may be paying month to month for something you no longer need. Out-of-contract mobile broadband is the classic case.
If a payment was taken in error or after you cancelled, the Direct Debit Guarantee entitles you to an immediate full refund from your bank.
If you think you are being overcharged
Complain to Three first. If it is not resolved within eight weeks, or you reach deadlock, you can take it to the telecoms ombudsman — Three's own complaints code names which scheme covers it. That route is free.
🛡️ Build your recovery plan
Tick what applies to you. The order below is deliberate: most of these organisations will ask for your Action Fraud reference number, so doing it in this sequence saves you making the same call twice.
Nothing ticked yet: the steps below are the ones that apply to everyone. Tick a box above to add the rest.
- 1
Report it to Action Fraud and get your crime reference number
Action Fraud: the national reporting centre for fraud
- Onlinereportfraud.police.uk
- Phone0300 123 2040
Do this second, and do it before you contact anyone else. Almost every organisation in this list (lenders, credit reference agencies, debt collectors) will ask for the crime reference number Action Fraud gives you, and without it you end up making the same call twice. It also creates the official record you'll rely on if you have to dispute anything later. Expect an update within 28 working days, though that's about the investigation, not about clearing your name; that part is on you and starts now.

Get all three credit reports and read every line
Experian, Equifax and TransUnion
- Experian0800 013 8888
- Equifax0800 014 2955
- TransUnion0330 024 7574
All three, not one. Lenders report to different agencies, so a fraudulent account can sit on one file and be invisible on the others: checking a single report is the most common way people miss the second and third account. You're looking for accounts you didn't open, searches you didn't authorise, and addresses linked to your name that you've never lived at. That last one matters more than it sounds: a linked address you don't recognise is often how the fraud was set up in the first place.

Add a CIFAS protective registration
CIFAS: the UK fraud prevention service
- Onlinecifas.org.uk
- Phone0330 460 9601
This puts a warning flag against your name in the National Fraud Database, so member organisations run extra identity checks before granting credit in your name. It costs £30 and lasts two years. It does not affect your credit score, and it doesn't touch accounts you already hold, but it will make your own applications slower, which is the trade-off. If someone has your details, that's usually a trade worth making. Note that not every application is checked against the database, so treat it as a strong deterrent rather than a lock.

Check you're on the electoral register at the right address
Your local council
A quick one that's worth doing while you're here. The electoral roll is one of the main ways lenders confirm you live where you say you do, and being missing from it both weakens your own applications and makes it easier for someone to claim your identity elsewhere.

Escalate if you get nowhere
Financial Ombudsman Service, or the ICO
- Financial Ombudsman0800 023 4567
- ICOico.org.uk
If a bank refuses to refund you, or a lender won't remove an entry it has accepted is fraudulent, complain to the firm first and give it eight weeks. After that, or as soon as you get a final response, take it to the Financial Ombudsman. It's free and its decisions bind the firm. Where the argument is specifically about inaccurate data staying on your credit file, the Information Commissioner's Office can also look at it. Both routes cost you nothing.

Close the door behind you
You
Change passwords on your email account first, not your banking: email is the master key, because it's where password resets land. Turn on two-factor authentication wherever it's offered. If documents were lost or stolen, report the passport or driving licence to the issuing body so it can be flagged. And set a reminder to re-check your credit reports in three months: fraudulent applications sometimes surface long after the original breach.
Contact details and process reflect Action Fraud, CIFAS, the credit reference agencies and National Debtline guidance for England and Wales. Scotland reports fraud through Police Scotland on 101 rather than Action Fraud; the rest of the process is the same. General information, not legal advice: free, independent help is available from National Debtline, Citizens Advice and StepChange.
