The Final Countdown: How Your Opening Read
& Final Bill Are Calculated

We’re not in the habit of gambling here at Igloo. But if we had to put money on two questions we’ll be asked at some point today they’d be these:

“What happens with my opening meter reading?”


“When will I receive my final bill from my old energy supplier?”

What happens in those days before you bid your old energy supplier farewell and begin your billing with a brand new one is a big source of confusion among consumers. And it’s one of the main reasons people are still reluctant to switch.

But, believe us, the process isn’t only easy; it’s also beneficial. After all, no one wants to pay more for their gas and electricity than they actually have to.

Why We Ask For An Opening Meter Reading

When you meet someone for the very first time what do you know about them?

Nothing right?

Well, the same goes for us when we first meet you. We need to get an idea of what your meter readings currently stand at. So, we have to ask.

Only by opening your account with up-to-date readings can we accurately bill you. Which is why we ask you to supply this reading between 5 days before and 5 days after your supply start date, but don’t worry we will remind you by email.

What Happens To My Opening Meter Readings?

We’re glad you asked.

Once we have your opening readings we submit them to an industry middleman called the Data Collector. Who then passes them on to your old supplier, this is the official way of doing things. Think of this as a digital handshake.

The data collector then give us a confirmation, the nod that that everything is good to go. And once this is received the old supplier can start producing your final bill. Magic.

Your Final Energy Bill Explained

The final step in leaving your old supplier is settling up your account. They’ll use the agreed readings to generate your final bill. Which could take up to 6 weeks to arrive. So don’t panic if it doesn’t show up right away. However in our experience it doesn’t take quite this long.

Any credit you’re owed should be refunded within 14 days of receipt of your final bill, via their preferred payment method. So if you have overpaid you’ll be reimbursed in full, we start billing you from the opening read date, the same date your old supplier stops billing you. You’ll never pay for the same energy twice.

And if you want to credit to your Igloo account with any extra cash we’ll reward you with 3% interest (up to £1000). So instead of your money just sitting there, it’s actually increasing in value too.

Neat huh?

What If I Disagree With Final Bill Readings?

This is rare, but if you do think your final bill or opening meter readings have been recorded incorrectly simply pick up the phone and tell us so.

We have a tried and tested process of disputing opening reads, so you’re in safe hands.

We’ll look into it with all the urgency it deserves until everything is smoothed out and hunky-dory again.

So, To Summarise…..
