A supplier cannot disconnect a business for non-payment without following a defined process: prior notice, an offer of a payment plan for microbusinesses, and in most cases a warrant obtained through the magistrates' court for forced entry. A formal billing dispute or an agreed payment plan stops disconnection proceedings. Acting quickly at the first notice stage is far more effective than waiting until enforcement begins.

The Legal Framework for Commercial Energy Disconnection
The right to disconnect a non-domestic electricity or gas supply for non-payment is governed by the Gas Act 1986 and the Electricity Act 1989, as modified by subsequent secondary legislation, and by the supplier's Standard Licence Conditions (SLCs) issued by Ofgem. These create a layered set of procedural requirements that suppliers must satisfy before disconnection can lawfully occur.
The starting point is that disconnection is a last resort, not a first response to non-payment. Ofgem's licence conditions require suppliers to take a series of steps before proceeding to disconnection: notifying the customer of the debt, engaging with the customer to explore repayment options, offering a payment plan to microbusiness customers, and issuing formal notice before any disconnection action is taken.
Where the supplier and customer have a live and genuine billing dispute, the supplier is not entitled to disconnect for the disputed amount while the dispute is in progress. The business should not be placed in a worse position because it is exercising its right to dispute an incorrect charge. Disconnecting a customer for non-payment of an amount that is subject to a formal dispute is a breach of the supplier's licence conditions and is reviewable by Ofgem and the Energy Ombudsman.
Specific Protections for Microbusiness Customers
Microbusiness customers, as defined by Ofgem's SLC 7A (consumption below 100,000 kWh electricity or 293,000 kWh gas per year, or fewer than 10 employees with turnover or balance sheet below EUR 2 million), benefit from enhanced protections against disconnection.
Under Ofgem's licence conditions, suppliers must offer a microbusiness customer a payment plan before commencing disconnection proceedings where the customer is in financial difficulty. The offer must be made in good faith and must represent genuinely affordable repayment terms. A token offer of a plan with monthly repayments that would be unworkable given the business's demonstrated financial position does not satisfy the obligation.
Suppliers must also ensure that microbusiness customers are aware of their right to escalate a complaint to the Energy Ombudsman and that any disconnection action is paused while a legitimate Ombudsman referral is pending. Proceeding to disconnection while a complaint is being investigated is a serious licence breach.
Prior Notice Requirements
Before a supplier can disconnect a commercial supply, it must issue formal written notice to the business at the supply address (and to any other registered contact address) specifying the amount owed, the period it covers, and the date on or after which disconnection may occur if the debt is not resolved. The notice period is not identical across all circumstances, but Ofgem's licence conditions and industry practice require a minimum period that gives the business a realistic opportunity to respond.
The notice must be clearly labelled as a formal disconnection notice, not obscured within routine billing correspondence. Where a business receives what appears to be a standard invoice but contains within it a notice that disconnection will follow, this is poor practice that suppliers have been required to address through Ofgem enforcement action.
Upon receipt of a disconnection notice, the business should:
- Identify whether the debt is genuine and undisputed, or whether it includes amounts that are subject to a legitimate billing dispute
- Contact the supplier immediately in writing, not by phone, to acknowledge receipt and set out the business's position
- Request a payment plan if the debt is genuine but the business cannot pay in full immediately
- Raise a formal complaint if any part of the debt is disputed
The Warrant Process: How Forced Entry Works
Where a supplier wishes to disconnect a supply at premises that are occupied and the occupant does not consent to the disconnection, the supplier must obtain a warrant from the magistrates' court authorising entry. The warrant process is governed by the Gas Act 1986 (Schedule 2B) and the Electricity Act 1989 (Schedule 6) for their respective supplies.
To obtain a warrant, the supplier must demonstrate to the magistrates' court that:
- There is a valid debt or other entitlement to disconnect
- The required prior notice has been given
- Entry has been refused or is expected to be refused
The business is entitled to be heard by the court before the warrant is granted and can present evidence that the debt is disputed, that a payment plan has been offered but not properly considered, or that disconnection would cause disproportionate harm. Where the court grants the warrant, it will specify the date range during which it may be exercised and any conditions.
In practice, most commercial disconnections for non-payment do not reach the warrant stage. The combination of prior notice, payment plan discussions, and the cost and time involved in obtaining a warrant creates strong incentives for both parties to reach an agreement before enforcement proceedings begin.
Practical Steps to Prevent Disconnection
The most effective actions at each stage of the disconnection process are:
On receipt of a debt notice: Respond in writing within five working days. Confirm whether the debt is accepted or disputed. If accepted and unaffordable, request a payment plan immediately. Do not ignore the notice.
Where the debt includes a disputed element: Pay the undisputed portion promptly to demonstrate good faith and raise a formal written complaint about the disputed element. The supplier cannot disconnect for the disputed amount while the complaint is in progress.
Where a formal complaint is at deadlock: Refer to the Energy Ombudsman (for microbusiness customers). Inform the supplier in writing that the referral has been made. The supplier must pause disconnection action while the Ombudsman investigation is pending.
Where the debt is genuine and a payment plan is needed: Provide evidence of the business's financial position to support the affordability assessment and propose specific monthly repayment terms. A written proposal from the business is more likely to result in an agreed plan than waiting for the supplier to set terms unilaterally.
Vulnerability and Safeguarding Considerations
Where business premises also serve a residential function, such as a live-work unit, a pub with residential accommodation, or a care facility, the supplier must take into account the impact of disconnection on any residents or vulnerable persons before proceeding. The Gas Act 1986 and Electricity Act 1989 both contain provisions limiting disconnection where it would endanger health or safety.
Suppliers are required under their licence conditions to maintain processes for identifying vulnerability in their customer base. Where a business has previously notified the supplier of special circumstances, such as the presence of medical equipment dependent on the electricity supply, this must be taken into account in the disconnection assessment.
Frequently Asked Questions
Editorial disclaimer: The answers below are provided for general guidance only. The specific rights available in a disconnection situation depend on the terms of the supply contract, the business's classification as a microbusiness or otherwise, and the nature of the debt. Contact Citizens Advice or an independent energy adviser before the situation escalates to enforcement.
Can a supplier disconnect my business without any warning?
No. Under Ofgem's Standard Licence Conditions and the Gas and Electricity Acts, a supplier must issue formal prior notice before disconnection can occur. The notice must specify the debt amount and give the business a realistic opportunity to respond. Disconnection without prior notice is a breach of the supplier's licence and can be reported to Ofgem and raised as an urgent complaint with the Energy Ombudsman.
Does a billing dispute automatically stop disconnection?
A formal, written billing dispute raised with the supplier stops disconnection proceedings for the disputed amount. The supplier cannot enforce disconnection for a charge that is the subject of a live complaint. The undisputed portion of any debt remains payable and the supplier can pursue recovery action for that element while the disputed portion is being investigated. Keeping the two elements clearly separated in writing is essential.
How quickly can a supplier reconnect after debt is cleared?
Once the debt is cleared or a payment plan is agreed, reconnection should be arranged promptly. The timeframe depends on whether the disconnection involved a physical meter intervention or a remote disconnection on a smart or HH meter. Remote reconnection can be completed within hours. Physical reconnection requiring a meter operator visit typically takes 1 to 5 working days. Suppliers are required to prioritise reconnection once the grounds for disconnection are resolved.
Can a landlord be disconnected for a tenant's energy debt?
The registered account holder is liable for the debt. Where the premises are supplied on a landlord account and the energy is sub-metered to tenants, the landlord is the account holder and faces disconnection risk for unpaid charges regardless of the sub-meter arrangements with tenants. Where supply is in the tenant's name, the landlord's connection is not directly at risk from the tenant's account, though vacant period liability can create complications.
What is the Debt Assignment Protocol and how does it relate to disconnection?
The Debt Assignment Protocol (DAP) is an industry mechanism that allows a business in arrears to switch supplier by transferring the debt to the gaining supplier, who agrees to manage repayment as part of the new supply arrangement. DAP can prevent disconnection by enabling a fresh start with a new supplier willing to offer a payment plan. Both the losing and gaining supplier must agree to the assignment, and the business must consent to the debt transfer terms. DAP is most relevant where the existing supplier is unwilling to offer acceptable payment plan terms but another supplier is prepared to take on the account and the associated debt.
