First Utility Bill at a New Address Is Huge? Here's Why and What to Do

Why first bills after moving are almost always wrong

When you move into a new property, the utility account is transferred to your name with an opening meter read. That opening read is the baseline — everything you are billed from this point is calculated from it. If the opening read was estimated too low, or if it recorded the previous tenant's outstanding usage, you will be paying for consumption that was never yours. This is one of the most common and most correctable billing errors.

Step 1: Check whether the opening meter reading is correct

The day you moved in, what was the meter reading? If you took a photo (which you should always do), compare that number against the opening reading on your first bill. Even a small difference — say, 50 kWh — can translate to a meaningful overcharge.

• Check your move-in photos or email records for the reading you noted on the day
• Find the opening meter reading on your first bill
• If your opening read is lower than your photo shows, you are being billed for the previous tenant's usage
• If you have no record, contact the previous tenant or the estate agent — they may have move-out photos

Step 2: Check for a catch-up bill from estimated reads

If the property sat empty, or if the previous tenant never submitted readings, the supplier may have been estimating usage for months before your arrival. Your first bill may include a reconciliation of all those estimates. This is legal — but you should not be paying for any of it. The catch-up should only cover the period before your tenancy began.

• Look at the billing period on your first bill — does it start before your move-in date?
• If the bill period starts earlier than your move-in date, contact the supplier and ask for the bill to be split at your move-in date
• Request that any estimated read catch-up before your tenancy be removed from your account

Step 3: Contact the supplier with your evidence

Write to your supplier — email is best for creating a paper trail. Provide your move-in date, your verified opening meter reading, and any photos or documents you have. Ask them to recalculate your bill from the correct opening read. Most suppliers will process this without dispute once you provide the evidence.

• Use the subject line 'Opening meter read dispute — [account number]'
• Attach your move-in meter photo
• State exactly what you believe the opening read should be and why
• If they cannot verify the read, ask them to obtain it from the distribution network operator (DNO), who holds the official record

Always photograph the meter on move-in day

The single most effective protection against first-bill disputes is a timestamped photo of every meter on the day you move in. Gas, electricity, and water. Do it before you unpack a single box. This one habit eliminates the most common source of billing disputes for movers and is free insurance against any supplier or landlord claiming you started with a different reading.
