Notes
Can my energy supplier cut me off for debt in the UK?
Your supplier can disconnect you for unpaid bills, but only after following strict legal steps and only if you are not in a protected group. Suppliers cannot disconnect vulnerable customers (over 60, disabled, families with young children, or chronically ill) at any time. Nobody can be disconnected between 1 October and 31 March.
Before acting, suppliers must offer a repayment plan, prepayment meter, or debt-relief scheme, and must give at least 28 days' formal notice. If you have a prepayment meter, supply can be restricted remotely without a warrant. You can also challenge an inaccurate bill via Ofgem before any debt action proceeds.
The short version:
- Disconnection is legal, but suppliers must follow strict procedural rules and cannot disconnect vulnerable households at all
- Winter protection (1 October to 31 March) applies to everyone; no one can be disconnected during this period
- Suppliers must offer a repayment plan, prepayment meter, or debt-relief options before any disconnection notice
- Prepayment-meter users can be remotely restricted (not fully disconnected) with less warning and no warrant needed
- If your bill is inaccurate, you can challenge it via Ofgem before any debt action takes place
Who is protected from disconnection?
Certain households cannot be disconnected for debt under any circumstances. This covers anyone aged 60 or over, anyone with a disability or long-term illness, families with a child under 5, and pregnant women. The protection applies regardless of how much you owe.
You must tell your supplier you are vulnerable. Contact the vulnerability or social tariff team directly, not the general debt line.
What must suppliers do before disconnecting?
Suppliers must issue a formal warning notice giving you at least 28 days to pay or propose a payment arrangement. The notice must state the debt, the amount owed, and your right to challenge the bill.
During those 28 days, they must try to contact you to discuss a repayment plan, debt-relief scheme, or prepayment meter. If you do not respond and you are not protected, they can apply to a court for a warrant. Without a warrant, they cannot enter your property.
| Step | Timeline | What you can do |
|---|---|---|
| 1. Formal warning notice | At least 28 days before action | Pay in full, agree a plan, or challenge an inaccurate bill |
| 2. Attempts to contact you | During the 28-day period | Respond with a proposal; offer a repayment arrangement |
| 3. Court warrant application | After 28 days if no payment | Request a hearing; explain vulnerability or hardship |
| 4. Physical disconnection or meter installation | Only after warrant granted | Comply, or seek emergency financial advice |
What about prepayment meters?
If you have a prepayment meter, your supplier can restrict supply remotely without a court warrant. Once your balance hits zero, you lose heating, hot water, and electricity.
You can owe up to £500 before your supplier can act to prevent top-ups. Above that threshold, they may apply for a debt-restriction meter or pursue court action. Vulnerable customers cannot have their prepayment meter restricted, even if they owe money.
What if your bill is wrong?
Dispute an inaccurate bill before any debt action proceeds. Contact your supplier and ask them to investigate. If they reject your challenge, escalate to Ofgem free of charge. Ofgem can force a correction and refund overcharges, and a valid dispute can delay or cancel disconnection. Raise the issue promptly; do not wait.
What suppliers are legally forbidden from doing
The strongest protection is knowing what suppliers cannot do. They cannot disconnect without a court warrant (except via prepayment-meter restriction). They cannot disconnect without first offering a repayment plan. They cannot disconnect vulnerable households or anyone in winter, regardless of debt size. They cannot refuse to investigate a bill dispute. They cannot charge you for a prepayment-meter warrant if you are vulnerable.
They cannot cut off water supplies (water companies operate under different rules). They cannot act if you are in a Breathing Space moratorium, a 60-day legal pause on debt action. These are enforceable legal duties under the Utilities Act 2000 and Consumer Rights Act 2015. If your supplier breaches any of them, you can complain to Ofgem and claim compensation.
When to get professional help
If your supplier has issued a disconnection notice or applied for a court warrant, contact Citizens Advice or National Debtline (0808 808 4000) immediately. They can confirm whether the procedure was lawful and help negotiate. If you are vulnerable or in winter, a debt adviser can help you claim that protection formally. If you face court proceedings, you may qualify for legal aid via a local law centre.
If Ofgem's informal dispute process stalls, escalate to the formal complaint procedure. It is free and no lawyer is needed.
Common questions
Can my supplier cut me off without warning?
No. Suppliers must issue a formal written notice giving you at least 28 days to pay or agree a plan, and must try to contact you. Only after these steps can they apply for a court warrant.
What if I am on a fixed-rate tariff?
Fixed-rate protection covers the unit rate and standing charge only, not debt. Disconnection rules are the same regardless of whether your tariff is fixed or variable.
Can my water company cut me off for debt?
No. UK water companies are forbidden by law from disconnecting domestic customers for non-payment. They can pursue court action or install a meter, but cannot shut off supply.
What is a Breathing Space moratorium and does it stop disconnection?
A Breathing Space is a 60-day legal pause on all debt action, including disconnection. To qualify, you must have multiple debts and be in a mental health crisis or seeking debt advice. Suppliers cannot disconnect or issue warnings during this period.
Can I switch supplier if I owe my current supplier money?
Yes, but you may not be able to access all tariffs. On a prepayment meter you can switch if your debt is under £500. On a standard meter you can switch, but your old supplier will pursue the debt separately.
