Can I switch business energy supplier if I owe money?
Usually not until the debt is settled or an arrangement is in place. Your current supplier can object to the transfer where money is owed, which stops the switch. The practical route is to agree a payment plan first, get confirmation that the objection will be lifted, and line up the new contract for the day it is.

What an objection is
When a new supplier tries to register your meter, your existing supplier gets a window in which to object. An unpaid balance is the most common valid reason. The switch simply stops; you stay where you are, usually on the rate you were trying to leave.
Getting it lifted
- Get the balance in writing and check it. Estimated readings and unbilled periods inflate a surprising number of "debts" — see my bill is estimated, how do I get it corrected?
- Ask for a payment arrangement. Suppliers will often accept a schedule rather than a lump sum, and many will lift the objection once the arrangement is live and being kept to.
- Get the lift confirmed in writing before the new supplier submits, so the registration is not rejected a second time.
While you are stuck
Do not simply sit on the default rate. If you are out of contract at 35–45p per kWh while you clear a balance, the debt grows faster than you can pay it down. Ask your existing supplier to move you onto a fixed rate with them in the meantime — that is usually available even where a switch is blocked, and it stops the bleeding.
If the debt is disputed
A genuinely disputed balance is different from an unpaid one. Put the dispute in writing, ask for the objection to be withheld while it is investigated, and escalate to the Energy Ombudsman if it reaches deadlock. Suppliers should not use an objection to hold a customer on a disputed figure.
