The standard grace period before disconnection is 28 days
If you miss an electricity bill payment, you are not disconnected immediately. Ofgem rules give your supplier 28 working days after the payment due date to send a reminder and start the formal disconnection process. The 28-day clock starts on the bill’s due date, not the date the bill was issued or posted. Your supplier must also send a reminder notice at least 7 days before any disconnection can take place (Ofgem, Standard Licence Condition 27 – Disconnection of Domestic Premises, 2026).
You have 28 working days after the due date before disconnection can start. Ofgem rules require your supplier to send a reminder and final notice during this period, and they must offer a payment plan before cutting power.

Suppliers must follow a strict legal process before cutting power
Before your supplier can disconnect your electricity, they must follow a three-step process with minimum time gaps between each step. First, they issue a reminder notice. Second, they send a final notice. Third, they deliver a disconnection warning. Each notice must give you a reasonable time to pay or respond. Ofgem rules also prohibit disconnection on a Friday, weekend, bank holiday, or the day before a bank holiday. Throughout this process, your supplier must offer you a payment plan before they proceed with disconnection (Ofgem, The Gas and Electricity (Disconnection) Regulations 2026).
What happens after 28 days of non-payment
Once 30 days have passed since your payment was due, your supplier can register the debt with a credit reference agency. This will affect your credit score and ability to get loans or mortgages. After 28 days, the supplier may apply to a county court for a warrant of entry to install a prepayment meter. Under 2026 rules, prepayment meter installation is mandatory for most debts over £200. This means the supplier can fit a meter that requires you to pay upfront for electricity, even if you do not agree (Ofgem, Prepayment Meter Code of Practice 2026).

How to avoid disconnection if your bill is past due
Contact your supplier as soon as you realise you cannot pay. Under Ofgem rules, your supplier must offer you a payment plan that you can afford. You do not need to pass a credit check to request a “time to pay” arrangement. If you are over 60, disabled, have young children, or have a medical condition, you can register for the Priority Services Register. This gives you extra protections, including a 14-day delay before disconnection and free access to the supplier’s complaint process (Ofgem, Priority Services Register Guidance 2026).

What to do if your supplier disconnects you unfairly
If your supplier disconnects you without following the 28-day notice period, or on a prohibited day, you can complain to the Energy Ombudsman. Ofgem can fine suppliers up to 10% of their annual turnover for disconnecting customers without following procedure. If the disconnection was unlawful, your supplier must reconnect you within 24 hours. Keep copies of all bills, reminder notices, and correspondence. The Ombudsman’s decision is binding on the supplier but not on you (Energy Ombudsman, Complaint Handling Procedures 2026).
How to verify your supplier’s disconnection rights
All domestic energy suppliers must be licensed by Ofgem. You can check whether your supplier holds a valid licence on the Ofgem Supplier Register online. If your supplier has obtained a warrant to enter your home to install a prepayment meter, that warrant must come from a county court. You can verify the warrant by contacting the court directly. Only TrustMark-registered contractors are allowed to install prepayment meters under warrant (Ofgem, Supplier Licensing Guidance; TrustMark, Energy Metering Standards 2026).
