The official deadline before your supplier can cut off your electricity
If you miss an electricity bill, your supplier cannot simply turn off your power the next day. Strict rules set by Ofgem, the energy regulator, dictate exactly how long you have before disconnection becomes a possibility. These rules are built to protect you from losing your electricity supply without fair warning and a chance to resolve the debt.
Your electric bill can be late for 28 days past the due date before disconnection is possible, but only if you owe £200 or more. Late fees usually start after 14 days, and credit damage begins after 30 days. Compare your supplier's policy to avoid surprises.
- Disconnection requires £200+ debt and 28+ days past due.
- Late-payment fees typically start after 14 days.
- Credit score damage begins after 30 days overdue.
- Suppliers must offer a payment plan before disconnection.
- Check your contract for waived late fees since the energy crisis.

The direct answer is that your supplier cannot disconnect you unless you owe at least £200 in total and have been in arrears for a minimum of 28 days past the bill’s due date. Before any disconnection proceedings begin, your supplier must first offer you a “payment plan” that you can afford. This means they must agree to a schedule of instalments based on your financial circumstances, not simply demand the full amount immediately (Ofgem, Standards of Conduct for Domestic Customers, 2026).
How many days you have from the bill date before late fees apply
Late-payment fees are another concern, but they do not kick in immediately. Most suppliers give you 14 days from the date the bill is issued to pay without incurring any extra charge. After that 14-day window, a late-payment fee of typically £10 to £15 can be added to your account. However, some suppliers have voluntarily waived these fees since the energy crisis, so it is worth checking your contract or contacting your supplier directly (Ofgem, Late Payment Charges and Debt Collection, 2026).
The maximum grace period before your credit score is affected
A missed electricity bill can also damage your credit score, but not immediately. Your account is not reported to credit reference agencies for a missed payment until you are at least 30 days overdue. Once reported, a missed payment can remain on your credit file for six years, which can affect mortgage and loan applications during that period. If you pay within the first 30 days, the missed payment should not appear on your credit report at all (Experian UK, How Utility Bills Affect Your Credit Score, 2026; Ofgem, Debt and Credit Reporting, 2026).
Quick numbers

|---|---|---|
| Day 0–14 | No action; payment due date passes. | None |
| Day 15–28 | Late-payment fee applied. | £10–£15 |
| Day 29–42 | Credit score warning recorded; supplier sends reminder letter. | Missed payment noted on credit file for six years |
| Day 43–56 | Supplier may apply for a warrant to enter your home and disconnect. | Court warrant application |
| Day 57+ | Disconnection possible (after court warrant and 7-day notice). | Power cut off |
When the supplier must offer you a prepayment meter instead of cutting you off
If you owe debt and cannot pay the full amount, your supplier must offer a prepayment meter as an alternative to disconnection. This means you pay for your electricity as you use it, and any debt is recovered through a fixed weekly amount added to the tariff. The prepayment meter must be installed within 28 days of your agreement. Importantly, you cannot be forced onto a prepayment meter if you have a medical condition or are over 75 years old (Ofgem, Prepayment Meter Installation Rules, 2026).
How to check if your supplier is following the correct process
The direct answer is that your electricity cannot be disconnected until you are at least 28 days past the bill’s due date, you owe more than £200, and the supplier has offered a payment plan and obtained a court warrant. If your supplier threatens disconnection before 28 days or without the £200 threshold, they are breaching Ofgem rules. You should immediately contact Citizens Advice or Ofgem’s consumer helpline to report the breach (Ofgem, Disconnection Rules for Domestic Customers, 2026). how to dispute an energy debt.
Eligibility for the Priority Services Register if you are at risk of disconnection
If you are at risk of disconnection, you may qualify for extra protections through the Priority Services Register (PSR). You qualify if you are of pensionable age, have a disability, are chronically ill, or have a child under five. Being on the PSR means your supplier cannot disconnect you without first contacting your local council or a designated carer. They must also give you extra time to pay and provide a free gas safety check if needed (Ofgem, Priority Services Register: Eligibility and Protections, 2026).
What to do if your electricity is cut off (and how to verify your installer)
If your electricity is cut off illegally (before 28 days, without a warrant, or without a payment plan offer), contact the Citizens Advice consumer service immediately. They can help you challenge the disconnection and get your power restored. Only a supplier with an MCS-certified (or equivalent) installer can reconnect you. Always ask for the installer’s MCS registration number and verify it on the MCS register website before allowing any work (MCS Register, Consumer Guidance on Reconnections, 2026; Citizens Advice, Energy Complaints, 2026). how to switch energy supplier after debt.
