Business Energy Investigation Guide

My business energy supplier is blocking my switch. What should I do?

If your business energy transfer keeps failing, the first job is to find out exactly why.

Do not assume every failed transfer is a supplier objection.

Ask your current supplier what happened and ask the new supplier what happened when it tried to register the supply.

Then compare the answers.

The problem could involve an outstanding balance, a disputed bill, the existing contract, a Change of Tenancy, the wrong supply point, associated electricity supplies or another account or registration issue.

The solution depends on the reason.

Before submitting the switch again, establish what is actually preventing it from completing.

What should I check first?

  1. 1Ask the new supplier whether the transfer was actually objected to or failed for another reason.
  2. 2Ask your current supplier for the exact reason in writing.
  3. 3Check the MPAN or MPRN involved.
  4. 4Check your current contract end date and termination position.
  5. 5If debt is mentioned, establish the exact balance and whether it is correct.
  6. 6If you have already paid, confirm the payment has been allocated and the objection reason has been cleared.
  7. 7Check whether a Change of Tenancy or incorrect occupier record is involved.
  8. 8If there are several electricity supplies, confirm which MPAN is actually being transferred.
  9. 9Record every attempted transfer date and every reason given for the failure.
  10. 10Keep a record of the rates you are paying while the problem continues.
  11. 11Raise a formal complaint if the reason is wrong, unexplained or is not being corrected.
  12. 12Before another transfer is submitted, ask whether the underlying issue has actually been resolved.

Why has the switch been blocked?

Start here.

Ask the current supplier:

"Please confirm the exact reason my business energy transfer has been objected to or prevented from completing."

Ask for the answer in writing.

Do not settle for: "There's a problem with the account."

You need to know what the problem actually is.

It might involve:

  • An outstanding balance
  • A disputed balance
  • The terms of the existing contract
  • A Change of Tenancy
  • The wrong business being recorded against the supply
  • An electricity MPAN problem
  • Related or associated meter points
  • Another account or registration issue

The solution depends on the reason.

Was the switch actually objected to?

Customers often describe any failed energy transfer as an objection.

But first establish what actually happened.

Ask the new supplier:

  • Did my existing supplier formally object?
  • Did the registration fail for another reason?
  • Which MPAN or MPRN was submitted?
  • Was the application rejected, withdrawn or unsuccessful for another reason?
  • What exact reason was returned?
  • Do you need anything from me?
  • Will another registration need to be submitted once the problem is fixed?

You do not need to understand every industry code or data flow.

You do need a clear answer explaining what stopped the transfer.

If neither supplier has confirmed the technical reason, do not guess. Ask them to identify it.

Ask both suppliers what happened

Do not rely entirely on one side.

Ask your current supplier why the transfer did not proceed.

Ask your new supplier what happened when it attempted to register the supply.

Write down:

  • Attempted transfer date
  • MPAN or MPRN
  • Current supplier
  • Proposed new supplier
  • Reason given by current supplier
  • Reason given by new supplier
  • What action each organisation says is required
  • Who is responsible for completing that action
  • Whether another transfer needs to be submitted afterwards

If the explanations do not match, that becomes part of the investigation.

Which of these sounds like your situation?

My supplier says I owe money

Go to the debt investigation.

I don't owe them anything

Ask the supplier to identify exactly what balance or contractual reason it is relying on.

The balance is wrong

Treat the billing dispute and switching problem as connected but separate investigations.

I've already paid

Gather proof of payment and ask when the supplier account was updated.

They say I'm still in contract

Check the actual contract, end date and termination terms.

I've moved in or out

Investigate the Change of Tenancy and responsibility dates.

There's a problem with my MPAN

Check the physical supply and industry meter records.

I have associated MPANs

Establish which supplies are live, which are not and what relationship is recorded between them.

Nobody will tell me why

Ask for the exact reason in writing and raise a formal complaint if necessary.

The problem was fixed but I'm still being blocked

Ask whether the underlying account or industry record has actually been updated and whether another transfer attempt is now required.

My supplier says I owe money

Do not start by arguing about the switch.

Start with the balance.

Ask for:

  • The current outstanding balance
  • The invoices making up that balance
  • Any unbilled consumption that may still need to be invoiced
  • Payments and credits already allocated
  • The exact reason the supplier says the balance allows it to prevent the transfer

Then establish:

  • Is the balance correct?
  • Is it disputed?
  • Has it already been paid?
  • Can it be paid now?
  • Does the customer need to discuss repayment options?

Debt can be relevant to a business energy transfer objection, but the position depends on the contract, account and circumstances.

Business energy switching should not be assessed using domestic switching rules.

Ask for a settlement figure in writing

If debt is being given as the reason for blocking your switch, ask the supplier for a clear current balance.

Do not assume the amount shown on an old bill is still the amount required today.

The account may have:

  • New consumption
  • Additional invoices
  • Payments
  • Credits
  • Rebills
  • Adjustments

"What is the current outstanding balance on this account as of today?"

"Please confirm exactly what needs to happen for the transfer objection to be removed."

Keep both answers.

Ask your supplier for the exact position

Subject: Business energy transfer objection
My business energy transfer has not completed and I understand that my current supplier may have objected to the transfer.

Please confirm in writing:

1. The exact reason the transfer has been blocked or objected to.
2. The current outstanding account balance.
3. The invoices making up that balance.
4. Any unbilled charges that may still need to be added.
5. Any payments or credits not yet allocated.
6. Whether the account is currently recorded as being in contract.
7. The contract end date you hold.
8. Exactly what needs to happen before the objection can be removed.
9. Whether anything else on the account would prevent a new transfer from completing.

Please also confirm when the account will be updated once the relevant issue has been resolved.

What if I owe the money but can't clear the whole balance now?

Then there are two separate questions.

How will the outstanding balance be repaid?

And: what is the supplier's position on the transfer?

Ask the supplier what repayment options are available.

If you propose a repayment arrangement, make it realistic.

But do not assume that agreeing a payment plan automatically means the supplier must allow the transfer.

Ask that question directly and get the answer in writing.

If a repayment arrangement is agreed, obtain written confirmation of:

  • The amount
  • Payment frequency
  • Start date
  • Duration
  • How ongoing energy charges will be handled
  • What effect, if any, the arrangement has on the transfer objection

What if I dispute the debt?

Do not let the switching problem replace the billing investigation.

Explain exactly why the balance is disputed.

For example:

  • Incorrect meter readings
  • Estimated consumption
  • Missing payments
  • Wrong responsibility dates
  • Change of Tenancy
  • Incorrect meter information
  • Historic billing
  • Another calculation error

Ask the supplier to confirm:

  • The amount it says is owed
  • The amount recorded as disputed
  • The reason for the objection
  • What happens to the transfer while the billing complaint is investigated

Do not assume that saying "I dispute the debt" automatically removes the objection.

What if I don't owe my supplier anything?

We've dealt with businesses where the customer believed the account was clear but repeated transfer attempts were still being blocked.

If that happens, ask the supplier to identify the exact reason for the objection.

Do not simply keep saying: "I don't owe you anything."

Ask: "What specific contractual, account or registration reason are you relying on to prevent this transfer?"

  • If the supplier says there is debt, ask for the amount and invoices.
  • If it says you are still contracted, ask for the contract end date and relevant contract position.
  • If it identifies a meter or registration problem, investigate that separately.
  • If it cannot provide a clear reason, record that as part of a formal complaint.

Payment does not necessarily mean every connected system updates instantly.

Keep proof of payment.

Ask the supplier:

  • When the payment was allocated
  • What balance is now showing
  • Whether the objection reason has been cleared
  • Whether the account is now able to transfer
  • Whether the new supplier needs to submit another registration

Do not repeatedly submit new transfers until you know whether the underlying issue has actually been corrected.

My supplier says I'm still in contract

Check the contract rather than relying only on what somebody says over the phone.

Find:

  • The contract start date
  • The contract end date
  • The termination provisions
  • Any notice requirements
  • What the contract says happens after expiry

Business energy contracts can work differently from domestic tariffs.

Do not assume that reaching what you believe is the end date automatically means every transfer submitted before or around that date must succeed.

Ask the supplier to identify the contractual provision it says allows the transfer to be prevented.

Out of contract and deemed rates are not always the same thing

These terms are often used as though they mean the same thing.

They do not always mean the same thing.

Ofgem explains that a deemed contract can arise when a business uses energy without having agreed a contract with the supplier, including certain situations after moving premises.

Ofgem also distinguishes an out of contract rate, where the previous business contract itself says what happens after it ends.

If you are paying high rates while a switch problem is being resolved, establish what type of rates the supplier says you are actually on.

Ask for:

  • The tariff or rate name
  • The unit rates
  • The standing charge
  • The date those rates started
  • Why they apply

Not every rate charged after a fixed contract ends is necessarily a deemed rate. Ask the supplier what tariff or rate type applies, when it started and why.

Keep a record of what the delay is costing you

If your business remains on expensive rates because a transfer cannot complete, preserve the evidence.

Keep:

  • The date your previous contract ended
  • The rates that applied afterwards
  • The date you agreed the new contract
  • The proposed new rates
  • Every attempted transfer date
  • Every objection or failure date
  • The reason given
  • The date you first asked for the problem to be corrected
  • The date it was eventually resolved

Evidence of extra cost can be relevant to a later complaint or remedy if an error is established. It does not mean reimbursement or compensation is automatic.

Is there a Change of Tenancy problem?

If somebody has moved into or out of the premises, establish who is actually recorded as responsible for the supply.

Check:

  • The Change of Tenancy date
  • The previous occupier
  • The new occupier
  • The evidence supplied
  • The opening or closing meter reading
  • The legal entity on the account
  • Whether the supplier has completed the Change of Tenancy

Do not assume a transfer problem will fix itself while the underlying account still shows the wrong responsible party.

Is the correct electricity MPAN being transferred?

An MPAN identifies an electricity supply point.

If a site has several electricity supplies, do not assume the first MPAN you find belongs to the meter you are trying to move.

Match:

  • Physical location
  • Meter serial number
  • MPAN
  • Supplier account
  • Current status

This is especially important on:

  • Farms
  • Industrial estates
  • Business parks
  • Sites with separate workshops or units
  • Premises that have changed electrical configuration over time

What if I've been told my MPANs are associated?

We've dealt with cases where a live electricity supply could not transfer because industry records still showed a relationship with another MPAN.

If somebody tells you that your MPANs are associated, ask them to explain:

  • Which MPANs are involved
  • Which are currently live
  • Which are de-energised or otherwise no longer in normal use
  • What relationship is recorded
  • Why that relationship is preventing the transfer
  • Which industry party is responsible for correcting it
  • What action is actually required

Associated MPANs do not always prevent a transfer. The important question is what relationship is currently recorded and whether that relationship is actually causing the failed transfer.

A de-energised MPAN does not automatically disappear from industry records. Ask the supplier or relevant industry party to confirm the current status and whether any associated record needs correcting.

The responsible industry party needs to identify and correct the underlying record.

My old MPAN is de-energised. Why is it still affecting my live supply?

A physical or operational change at the premises does not necessarily mean every industry record connected with the old arrangement has already been updated.

If a de-energised supply appears to be affecting the transfer of a live supply, establish:

  • The status of each MPAN
  • The physical meter arrangement
  • Whether the old meter still exists
  • Whether the MPANs remain related in industry records
  • What record needs correcting

Do not use "disconnected", "removed" and "de-energised" as interchangeable terms. If the exact status is unclear, say so and ask the supplier or relevant industry party to confirm it.

My supplier and the DNO keep sending me back to each other

This is frustrating, but do not spend weeks acting as a messenger without first defining the problem.

Ask each organisation:

  • "What exactly do you believe is wrong?"
  • "What action needs to be completed?"
  • "Which organisation is responsible for completing that action?"
  • "What information have you already sent to the other party?"
  • "What happens next?"

Keep their answers in writing.

If one party says the other must act, ask them to identify the specific action required.

You do not need to become an expert in industry data flows just to get your business electricity supply transferred.

Don't get lost in industry terminology

During a complicated electricity transfer problem you may hear references to MPANs, registration, industry data, metering agents, DNOs, energisation status, associated supplies or industry flows.

Some of these may matter.

But your first question should remain simple:

"What is currently preventing this MPAN from transferring, and what exact action will remove that problem?"

Do not allow technical terminology to replace an actual diagnosis.

What if the problem has supposedly been fixed but the switch still fails?

Ask for confirmation that the underlying account or industry record has actually been updated.

Then ask whether:

  • The existing objection has been removed
  • The supply is now eligible to transfer
  • The gaining supplier needs to submit another registration
  • There are any other known reasons the transfer could still fail

Record the date you were told the issue was corrected.

If another attempt fails, ask for the new failure reason.

Do not assume it must be the same problem as before.

Get the important answers in writing

A two-minute explanation on the telephone is not much use if the next person gives you a completely different answer.

Keep:

  • Emails
  • Complaint references
  • Payment evidence
  • Contract documents
  • Transfer dates
  • Meter information
  • Screenshots where useful
  • Notes of telephone conversations

After an important call, record:

  • The date
  • Time
  • Department
  • What you were told
  • What should happen next

For a transfer that fails repeatedly, evidence matters.

When should I raise a formal complaint?

If the transfer keeps failing and:

  • The supplier cannot explain why the transfer keeps failing
  • The reason appears to be wrong
  • You have already resolved the stated problem
  • Incorrect account information is not being corrected
  • You are being repeatedly passed between organisations
  • The delay is continuing without a clear resolution

Ask the supplier to record a formal complaint.

Get the complaint reference.

State clearly what outcome you need.

Do not simply write: "Please sort this out."

Ask for:

  • The exact transfer problem
  • The action required
  • Who owns that action
  • A timescale
  • Confirmation when it is corrected
  • An explanation of what happens next

Can I take a blocked business energy switch complaint to the Energy Ombudsman?

Eligible microbusiness and Small Business customers may be able to take an unresolved supplier dispute to the Energy Ombudsman.

This can normally happen after:

  • The supplier issues a deadlock letter
  • The supplier has had more than eight weeks to consider the complaint

Small Business eligibility criteria:

  • Fewer than 50 employees or their full-time equivalent AND annual turnover of no more than £6.5 million or a balance sheet total of no more than £5 million
  • OR annual electricity consumption of no more than 200,000 kWh
  • OR annual gas consumption of no more than 500,000 kWh

Eligibility remains subject to the Energy Ombudsman's scheme rules.

Not every business qualifies.

Ofgem does not handle individual customer complaints.

What could the Energy Ombudsman do?

Where an eligible complaint is accepted and the Energy Ombudsman finds there has been a problem, possible remedies can include practical action, an apology and financial awards.

The Energy Ombudsman currently states that financial awards can be up to £20,000.

The outcome depends on the individual complaint. Compensation is not automatic.

Additional variable rate costs are not automatically refunded.

If you cannot answer one of these, that is probably your next question.

Common mistakes when a business energy switch is blocked

  • Repeatedly submitting another transfer without identifying the problem.
  • Assuming every failed transfer is a supplier objection.
  • Assuming debt is the reason without checking.
  • Paying an unexplained balance simply to try to force the switch through.
  • Assuming a payment immediately updates every relevant record.
  • Using the wrong MPAN.
  • Ignoring associated electricity supplies.
  • Assuming a de-energised MPAN has automatically disappeared from every industry record.
  • Treating a Change of Tenancy problem as a normal supplier switch.
  • Relying entirely on telephone conversations.
  • Not recording how long the problem has continued.
  • Not recording the rates being charged during the delay.
  • Allowing the supplier and DNO to send you backwards and forwards without establishing what action is actually required.

How we investigate a blocked switch

When a customer tells us their supplier keeps blocking a switch, we do not start by simply submitting the same transfer again.

We first establish what happened.

Was there an objection?

Was debt involved?

Is the business still in contract?

Is the supplier account showing the correct occupier?

Is the correct MPAN being transferred?

Are other electricity supplies involved?

Once the actual reason is known, we can work out what needs to be corrected before another transfer is attempted.

Why we've written this guide

We've helped businesses where energy transfers have been rejected repeatedly even though the customer believed there was no debt.

We've helped businesses with an outstanding balance who wanted to understand what needed to happen before they could leave.

We've dealt with customers stuck on expensive rates while a transfer problem remained unresolved.

And we've dealt with electricity supplies where related MPAN records prevented a live supply from moving to the new supplier.

The important lesson from all of them is the same.

Don't keep guessing.

Find the reason the transfer failed.

Then investigate that reason.

Frequently asked questions

Why is my business energy supplier blocking my switch?

There can be different reasons, including an outstanding balance, contractual restrictions, Change of Tenancy problems or electricity meter point and registration issues. Ask your current supplier for the exact reason in writing and ask the new supplier what happened when it attempted the transfer.

Can my business energy supplier stop me switching because I owe money?

Debt can be relevant to a business energy transfer objection, but the position depends on the contract, account and circumstances. Ask the supplier to confirm the balance, the invoices making it up and the contractual or account reason it says allows the transfer to be blocked. Business energy switching should not be assessed using domestic switching rules.

Can I switch business energy supplier if I have agreed a payment plan?

Do not assume that agreeing a repayment arrangement automatically means a supplier must allow the transfer. Ask the supplier whether the arrangement changes its objection position and get the answer in writing.

What if I don't owe my energy supplier any money?

Ask the supplier to identify the exact reason for the objection. If it says there is debt, ask for the amount and invoices. If it says you are still contracted, ask for the contract end date and relevant terms. If it identifies an MPAN or registration issue, investigate that separately.

I've paid my energy debt. Why is my switch still being blocked?

Ask when the payment was allocated, what balance is now showing, whether the original objection reason has been cleared and whether your new supplier needs to submit another transfer. Keep proof of payment.

My supplier says I'm still in contract. What should I check?

Check the actual contract start date, end date, termination provisions and any notice requirements. Ask the supplier to identify the contractual reason it says allows the transfer to be prevented.

What's the difference between out of contract and deemed business energy rates?

They are not always the same. Ofgem distinguishes deemed contracts, which can arise when energy is used without an agreed contract in certain circumstances, from out of contract rates that apply because an existing business contract says what happens after it expires.

What are associated MPANs?

Some electricity supply points can have related records. If those records are incorrect or no longer reflect the physical arrangement at the premises, they can sometimes complicate a transfer. Ask which MPANs are involved, what relationship is recorded and what needs to be corrected.

Why is a de-energised MPAN affecting my live electricity supply?

A change to the physical or operational supply does not necessarily mean every related industry record has already been updated. Ask for the current status of each MPAN, the relationship between them and what record is preventing the live supply from transferring.

Should I keep trying to switch if every transfer is rejected?

Not blindly. First identify why the transfer is failing. Repeated applications may not solve an unresolved debt, contract, Change of Tenancy or meter point problem.

My supplier and DNO keep sending me back to each other. What should I do?

Ask each organisation to state in writing what it believes is wrong, what exact action is required and which organisation is responsible for completing it. You should not have to guess which technical industry process is needed.

Can I claim back the extra money I've paid while my switch was blocked?

Do not assume compensation or a refund is automatic. Keep evidence of the attempted transfers, the reason for the delay, the rates you paid and the rates you expected to move onto. If an error is later established, that evidence may be relevant to your complaint and any remedy considered.

When should I complain about a blocked business energy switch?

Consider a formal complaint if the supplier cannot explain the failure, gives a reason you believe is wrong, does not correct an acknowledged problem or leaves the transfer unresolved without a clear plan. Get a complaint reference and state exactly what outcome you need.

Can the Energy Ombudsman help with a blocked business energy switch?

Eligible microbusiness and Small Business customers may be able to use the Energy Ombudsman after receiving a deadlock letter or after the supplier has had more than eight weeks to consider the complaint. Not every business qualifies.

Can The Best Energy Rates help if my business energy switch keeps being blocked?

Yes. We can help work through the contract, account balance, Change of Tenancy, MPAN or other information behind the failed transfer and help identify what needs to be corrected before another switch is attempted.

Is your business energy switch stuck?

If your transfer keeps failing and you cannot get a clear explanation, send us your latest business energy bill and the information you have about the rejected transfer.

We can help work through the contract, account, meter point and transfer history to identify what appears to be stopping the move.
