Why was my energy switch declined when I moved in?
Short answer
Most often because the supplier has not opened an account in your name yet, so your switch request lands on an account still carrying the previous occupier's balance. That balance is not your debt and you do not have to pay it. Open an account with the supplier already serving the address, give them your move-in date and an opening meter reading, then ask your new supplier to run the switch again.

A switch refused days after you move in feels like a problem with you. It almost never is. It is a paperwork gap between you and a supplier who does not yet know you exist, and the balance being objected to is usually not yours to pay.
What actually happened to your switch
A switch is not simply accepted or refused by a computer. The supplier already serving the property is given a window to object to losing you, and on a fresh move-in there is usually something on the account for them to object about.
- From the day you take responsibility for the property you are on a deemed contract with whoever already supplies it. Nobody signs you up and you did not choose it.
- When your new supplier requests the switch, the current supplier can ask for it to be prevented. The supplier that blocked it must then tell you the grounds and how to dispute or resolve them.
- On a new move-in the account is often still in the previous occupier's name, or has no opening reading, so it shows an unpaid balance that has nothing to do with you.
- Two different things can go wrong here and it is worth knowing which you have. A debt objection is a formal block under the supply licence. A missing account is a registration problem, which is faster to fix and more common on a recent move.
- Either way, it is a record-keeping gap, not a judgement about you, and the fix is to make the record right.

You do not pay for energy used before you moved in
Worth being blunt about, because suppliers chase the address rather than the person and the letters can be intimidating. The energy the last occupier used is not your bill.
- Citizens Advice states it plainly: you do not have to pay for energy that was used before you moved in.
- What you owe starts at your opening meter reading on the day you became responsible for the property, and not a unit before it.
- If you bought the property, that day is completion, which can be well before the day you actually moved your things in. Use the completion date.
- If the supplier asks you to prove it, a copy of your tenancy agreement or your completion statement is what they are asking for.
- Ask for the earlier balance to be separated from your account, so it stops travelling with the meter.
- This is a live problem across the industry, not a quirk of your supplier. Ofgem ran a call for input on energy debt in home moves that closed in January 2026 and is due to consult on new guidance for the process.

When a supplier is actually allowed to block a switch over debt
This is the part worth knowing, because it is the part that gets a wrongly blocked switch released. Debt is the only ground a domestic supplier can use, and it has two conditions. Both must be true.
- The supplier must have demanded the money from you in writing.
- That demand must have been at least 28 days ago, and the amount must still be unpaid.
- Both conditions are about you, the account holder. A supplier who has never billed you cannot have satisfied either of them.
- So if you have just moved in and have never had a bill from this supplier, a debt objection against you does not stand up. Say exactly that, in the words below.
- There is a second protection worth naming on the call. A supplier may not block a transfer where it knows, or has reason to believe, that the charges are entirely a disputed amount or its own error. Once it becomes aware of that, it has to help the transfer along.

What to say when you call them
Suppliers will only discuss an account with the person whose name is on it, so this is a call only you can make. Writing it is the part we can do. Read this out, or paste it into their web chat.
- First, find out who to call. Check any bill or letter already at the property, ask the landlord or letting agent, or use Find My Supplier or the Meter Number Helpline on 0870 608 1524 for gas. For electricity, your local network operator holds the record.
- "I moved into this property on [date]. The account is not in my name and I have never received a bill from you, so there are no outstanding charges owed by me and a debt objection against me is not valid."
- "My opening meter reading on that date was [reading]. Please open an account in my name from that date."
- "Any balance from before that date belongs to the previous occupier. Please separate it from my account."
- "I am formally disputing that balance. You cannot hold a transfer where the outstanding charges are entirely a disputed amount, so please withdraw the objection."
- "Please confirm in writing that the objection has been withdrawn."
- Have the tenancy agreement or completion statement ready to send while you are on the call. That is the proof they ask for, and sending it the same day saves a second call.

What to do if the supplier will not move
A call centre can simply repeat the objection. If that happens, you are not stuck, but you do need to move it out of the phone system and into the complaints process, because that is the only route with a deadline attached.
- Put the complaint in writing. The eight-week clock starts when the complaint is written down, not when you first phoned.
- Every supplier must have a complaints procedure and must tell you how to use it.
- Once eight weeks have passed, or the supplier sends a deadlock letter saying it will take the complaint no further, you can go to the Energy Ombudsman.
- The Energy Ombudsman is free to use, and its decision binds the supplier but not you, so you keep your options either way.
- You have twelve months from the deadlock letter, or from the end of the eight weeks, to bring the case.
- The Citizens Advice consumer helpline can talk it through with you before you get that far.

If the property has a prepayment meter, do this first
Prepayment turns the same problem into a sharper one, because the debt sits on the meter rather than on a statement, and topping up can quietly attach it to you.
- Do not use a key or card the previous occupier left behind, and try not to top up at all until you have spoken to the supplier.
- Ask the supplier for new keys or cards in your name, and ask them to take the earlier debt off the meter.
- If you had to top up before you got through to them, say so when you call. It is recoverable, but only if you raise it.
- You can still switch supplier with debt on a prepayment meter. Up to £500 can be assigned to your new supplier, and because gas and electricity are licensed separately that is £500 for each.
- The switch itself should complete within 5 working days once it is accepted, though the clock does not start until your 14-day cooling-off period ends unless you ask for it to start sooner.

We write the call, you make it
The supplier will only deal with the person named on the account, which is you, so we cannot make this call for you and would not want to be between you and your own supply. What Taupia can do is make sure you never make it blind.
- Add your address and move-in date before you move, and Taupia tells you which supplier already serves the property, so the first question on this page is answered before it becomes urgent.
- Compare tariffs against that starting point and get a switch ready to submit for the day you take responsibility.
- Store opening meter photos with the date attached, so the reading you need on the call is already on file.
- If a switch is objected to, Taupia gives you the wording above and the evidence to send with it. Nothing changes without your approval.
Five reasons a move-in switch gets refused, and what clears each one
| Why the switch was declined | What to do about it |
|---|---|
| The supplier has no account in your name yet | A registration gap rather than a debt block, and the fastest fix. Open an account from the day you took responsibility, with an opening reading, then ask for the switch to be run again. |
| A balance is showing from before you took over | Not yours. Send proof of your move-in or completion date and ask for the earlier balance to be separated from your account, not just noted. |
| You do owe this supplier money | Check both conditions. They must have demanded it from you in writing, and that demand must be at least 28 days old with the amount still unpaid. If either is untrue, say so. |
| Prepayment meter with debt on it | Ask for new keys or cards and for the debt to come off the meter. You can still switch, with up to £500 per fuel assigned to the new supplier. |
| Your rent includes bills | Check your tenancy first. If the landlord holds the supply contract, the switch is theirs to make rather than yours. If you are the named customer and they recharge you, it is still your switch. |
Common questions when a switch is refused
Why was my energy switch declined when I moved in?
Most often because the supplier has no account in your name yet, so the switch request lands on an account that still shows the previous occupier's balance and they object to it. Open an account with them from the day you took responsibility, give an opening meter reading, then ask your new supplier to request the switch again.
Am I responsible for the previous tenant's energy debt?
No. You do not have to pay for energy used before you moved in. Tell the supplier the date you took over, give them your opening reading, and send a copy of your tenancy agreement or completion statement if they ask for proof.
Can my supplier stop me switching if I owe them money?
Only in a narrow case. They must have demanded the money from you in writing, that demand must be at least 28 days old, and the amount must still be unpaid. A supplier who has never billed you cannot meet those conditions, so a debt objection on a brand-new move-in does not stand up.
How do I find out why my switch was objected to?
Ask the supplier that raised it. A supplier that blocks a transfer has to tell you the grounds and explain how you can dispute or resolve them, so you are entitled to a specific answer rather than a refusal.
What if the supplier still refuses?
Put the complaint in writing, because that is when the eight-week clock starts. After eight weeks, or as soon as you get a deadlock letter, you can take it to the Energy Ombudsman. It is free, and its decision binds the supplier but not you.
How do I find out who supplies energy to my new address?
Check any bill or letter already at the property, or ask the landlord or letting agent. Failing that, Find My Supplier and the Meter Number Helpline on 0870 608 1524 identify the gas supplier from your postcode, and your local electricity network operator holds the electricity record.
Can I switch energy supplier with a prepayment meter in debt?
Yes. Up to £500 of debt can be assigned to your new supplier, and because gas and electricity are licensed separately that is £500 for each. If you have just moved in, ask for new keys or cards first and ask for the previous occupier's debt to be taken off the meter.
Can I switch before I move in?
You cannot complete a switch before the day you become responsible for the property, because until then the supply is not yours to move. You can get one ready in advance and have it submitted for that day, which is what Taupia sets up for you to approve.
