Dairy Farm Electricity Billing Investigation: Approximately £144,000 in Credits
A catch-up electricity bill of £183,717.22 led to an investigation of meter register errors and historic billing. Challenging both issues resulted in approximately £144,000 of credits.

The catch-up bill
A dairy farm received a catch-up electricity bill of £183,717.22.
A bill of that size is alarming. The natural response is to ask how it is going to be paid. Our first question was different: is it right?
Dairy farms are significant electricity users. High consumption is not unusual. But the size of a bill is not, by itself, evidence that the bill is correct. We started with the evidence.
The meter register problem
Photographs of the actual meter readings were provided repeatedly during the investigation.
Those photographs were important because they provided evidence of what the physical meter was displaying, rather than relying solely on readings recorded against the account.
The investigation ultimately established that the Day, Night and Total readings had been mixed up.
Once the meter register issue was addressed, the customer's account was recalculated. The result was a credit of approximately £94,000.
On a multi-rate electricity meter, each register has a specific purpose. If readings are recorded against the wrong register, the supplier's billing system can be working from incorrect information even though numbers have technically been entered onto the account.
Why meter photographs matter
This is why we regularly ask customers with unusual electricity bills to photograph their meter.
A photograph can show much more than a number written in an email. Depending on the meter, it can help establish which register is being displayed and provide evidence that can later be compared with the readings and consumption being used for billing. Where a meter cycles through multiple screens, photograph each relevant screen and capture the register identifier where it is displayed.
The backbilling challenge
The meter register problem was not the only issue we challenged.
Part of the historic billing raised a separate question about backbilling. Backbilling is when a supplier seeks payment for energy that was used previously but was not accurately charged at the time.
For qualifying microbusinesses, Ofgem's rules can restrict suppliers from recovering charges for energy consumed more than 12 months before the charge recovery action, subject to important exceptions.
The protection does not mean every old business energy charge is automatically written off. The rules can include exceptions where obstructive or manifestly unreasonable customer behaviour prevented accurate billing.
We challenged the applicable historic charges in this case. That resulted in a further credit of approximately £50,000.
The result
| Issue challenged | Approximate credit |
|---|---|
| Incorrect treatment of meter registers | £94,000 |
| Backbilling challenge | £50,000 |
| Total credits | £144,000 |
The original catch-up bill was £183,717.22.
The important point is not simply the size of the credit. It is that the original bill was challenged rather than accepted at face value.
What this case shows
A large bill is not proof the bill is correct
The size of a catch-up bill reflects what the supplier has calculated, not necessarily what is owed. The calculation itself needs to be examined.
Photograph every meter register
Where a meter cycles through multiple screens, photograph each relevant screen and capture the register identifier where it is displayed. Keep the photographs.
Do not assume register information on the bill is correct
The readings recorded against each register in the billing system may not match what the physical meter was displaying. Photographs provide a check.
Treat backbilling as a separate question
Even where a billing error is corrected, the period being rebilled may raise separate questions about backbilling rules for qualifying microbusinesses.
The Best Energy Rates Desk
If a business receives a huge catch-up bill, our first question is not simply:
How are they going to pay it?
It is:
Is it right?
Start with the evidence. Look at the meter. Photograph the registers. Compare the readings with previous bills. Check which registers the supplier has used. Look at the period being rebilled and establish whether the business qualifies for backbilling protection.
A supplier producing a bill does not remove your right to question how that bill was calculated.
In this case, continuing to question the account resulted in approximately £144,000 of credits.
Received a large catch-up electricity bill?
Before agreeing a payment plan or accepting that the balance is correct, we can help investigate what has happened.
We can look at meter readings and photographs, estimated and actual readings, Day and Night registers, historic consumption, unusual changes in usage, catch-up charges, backbilling periods and the supplier's explanation of the balance.
Send us the bill and photographs of the meter and we will start with the numbers. No promise that every disputed bill is wrong. No promise that every business qualifies for backbilling protection. We investigate the evidence first.

Frequently asked questions
Can an electricity supplier use the wrong meter register?
Yes. On a multi-rate electricity meter, each register records consumption for a specific period or rate. If readings are entered against the wrong register in the supplier's billing system, the account can be billed on incorrect figures even though numbers have technically been recorded.
What are Day, Night and Total meter readings?
On a two-rate electricity meter, the Day register records consumption during peak hours and the Night register records consumption during off-peak hours. Some meters also display a Total figure. Each register has a separate identifier and must be read and recorded correctly.
Why can mixing up Day and Night readings cause problems?
Day and Night rates are priced differently. If the supplier records readings against the wrong register, the billing system calculates charges using the wrong rate for the wrong consumption figure. Over time, this can produce significant billing errors in either direction.
Should I photograph my electricity meter?
Yes. A photograph of the meter display provides evidence of what the physical meter was showing at a specific point in time. On meters that cycle through multiple screens, photograph each relevant screen and capture the register identifier where it is displayed. This can be important if a billing dispute arises later.
What is an electricity catch-up bill?
A catch-up bill is issued when a supplier recalculates an account and seeks payment for energy that was used previously but was not accurately charged at the time. This can happen after a meter exchange, a correction to estimated readings, or the identification of a billing error.
Can a business energy supplier backbill for more than 12 months?
For qualifying microbusinesses, Ofgem's rules can restrict suppliers from recovering charges for energy consumed more than 12 months before the charge recovery action. However, the protection is not absolute. Exceptions can apply where obstructive or manifestly unreasonable customer behaviour prevented accurate billing. Whether a business qualifies and whether exceptions apply depends on the specific circumstances.
What counts as a microbusiness?
Ofgem defines a microbusiness as a business that uses fewer than 100,000 kWh of electricity per year, fewer than 293,000 kWh of gas per year, or has fewer than 10 employees and an annual turnover or balance sheet total not exceeding €2 million. Qualifying microbusinesses benefit from additional protections under the supply licence conditions.
Does not sending meter readings mean I lose backbilling protection?
Not automatically. The backbilling rules focus on whether the supplier took reasonable steps to obtain accurate readings and bill correctly. Simply not providing readings does not necessarily constitute the kind of obstructive or manifestly unreasonable behaviour that removes protection, but each case depends on its own facts.
Should I pay a large catch-up bill before challenging it?
You should not simply accept a large catch-up bill without first understanding how it was calculated. Before agreeing a payment plan or making payment, it is worth reviewing the meter readings used, the period being rebilled, the rate applied to each register and whether any backbilling rules apply. Paying a bill does not necessarily prevent a later challenge, but it is better to raise questions before payment where possible.
Can The Best Energy Rates investigate an existing supplier bill even if I don't want to switch supplier?
Yes. Investigating a billing dispute or catch-up bill does not require switching supplier. We can review the account, examine the readings and billing history, and help challenge charges that appear incorrect, regardless of whether you want to move to a different supplier.
