How to request an independent electricity meter test
A shared-home evidence and billing workflow for requesting a statutory independent meter test and applying its written determination.
If an electricity meter still appears inaccurate after the supplier checks the account, the bill payer can request an independent meter test in England, Scotland, or Wales. Build the evidence first, ask about any supplier administration charge, record the removal reading and serial number, and wait for the examiner's written determination before recalculating the roommates' shares.
Rule out a billing or household change first
A high bill alone does not prove a faulty meter. Compare the billed meter serial number with the physical meter, then mark every reading as actual, estimated, or customer supplied. Check the billing period, unit rate, standing charge, tariff change, and whether an earlier estimate was corrected. A catch-up after low estimates can look like a sudden surge even when the meter is accurate.
Ask housemates about changes that are easy to miss: a portable heater, long-stay guest, dehumidifier, EV charging, immersion heater setting, or someone working from home. Compare like periods where possible, but do not present weather or occupancy guesses as meter evidence.
Take clear photographs of the meter reading and serial number on several dated occasions. Keep the original files. If an estimated bill conflicts with a household reading, follow the actual-reading reconciliation steps before escalating to a physical accuracy dispute.
Request the statutory independent test
First report the concern to the energy supplier that sends the bills. Ask it to explain the reading history and any checks already performed. If you remain unhappy, explicitly request an independent test rather than a routine engineer visit or meter replacement.
The Office for Product Safety and Standards explains the official electricity meter accuracy dispute process. Its guidance says the independent examiner checks the meter on site, the supplier's operative removes it and installs a replacement, and the original meter goes to an approved laboratory. The examiner then sends a written report called a determination.
The independent test itself is free, but the guidance warns that the supplier may charge for organising it if the meter is found to work correctly. Ask the supplier in writing whether it will impose a charge, how much it could be, and where that term appears before confirming the appointment.
Protect the evidence at the appointment
Have one resident attend who understands the complaint. On the day, photograph the old meter's serial number and final reading before removal. Also photograph the replacement meter's serial number and opening reading after installation. Record the appointment time and the names or identifiers of the examiner and supplier operative where provided.
Do not ask to keep or alter the removed meter. The official process depends on controlled removal and laboratory testing. Give the examiner a concise timeline of the disputed readings and explain whether the concern is fast registration, intermittent behaviour, or another observed problem.
When the determination arrives, save the complete document. If it says the meter is accurate within legal limits, return to tariff, reading, wiring, and household-use explanations. If it says the meter is inaccurate, the supplier should contact you to resolve the account. The determination may state how far the meter was outside the limits and, if possible, estimate how long that occurred.
Reconcile the corrected shared bill
Do not apply a guessed percentage to past roommate payments. Ask for a revised bill showing the correction period, readings, rates, standing charges, payments, and resulting balance. Match that bill to occupancy dates and the household's original allocation rule.
If overbilling produced a refund, return it to the people who funded the affected bills. If correction produces underbilling, ask the supplier about available payment arrangements before setting roommate deadlines. Keep any test-related administration charge separate from energy consumption so the household can decide who bears it under its dispute rules.
How HomeCo helps
Use HomeCo tasks for the supplier complaint, test appointment, determination, and corrected-bill review. Assign the appointment to the attendee and schedule a follow-up for the date the supplier promises a response. Post a household announcement with the old meter's final reading and the replacement's opening reading clearly labelled, leaving sensitive account details in the household's chosen secure storage.
Frequently asked questions
Is a supplier meter check the same as an independent test?
Not necessarily. Ask who will test the meter, where it will be tested, and whether you will receive the independent examiner's determination described by OPSS.
Can the supplier charge if the meter passes?
The test is free, but OPSS says you may have to pay the supplier for organising it when the meter is found to be working correctly. Get the possible charge in writing first.
Should roommates stop paying during the test?
Do not assume the dispute pauses payment obligations. Ask the supplier how to handle the contested balance, keep reserving each person's contribution, and document any agreed payment plan.
