Energy regulators Ofgem this morning have announced a new price cap of £3,549 to come into effect from October.
This means UK household energy bills will rise again by 80% - up from the current price cap level of £1,971.
Analysts at Cornwall Insight have suggested meanwhile that this could rise again in the new year to £3,616.
The last time the price cap rose in April, experts including Martin Lewis suggested taking meter readings the day before the new figure came into place.
This is so customers can tell their energy providers exactly much gas and electricity they are using before the price soars once again, reducing the risk of you being overcharged.

If you apply this logic again before October, then you should look to submit an energy meter reading on Friday, September 30, the day before everything goes up.
"That way you draw a line in the sand that says to your energy firm, I've only used this amount at the cheaper rate," Mr Lewis told viewers on his ITV show earlier this year.
"Don't start charging me more on the higher rate and estimating I use some of it afterwards."
Energy company E-On hit out at Mr Lewis in March after hundreds of thousands tried to submit their meter readings at the last minute for the April rise, causing its site to crash.
Companies such as British Gas and Scottish Power had similar problems during the end-of-March panic.
Ofgem has just announced that it will now review its price cap four times a year, instead of twice a year.
It will now review the price cap every January, April, July and October.
How to take meter readings
To send a meter reading, you need to record the first five numbers shown from left to right on your meter to your energy supplier.
You can do this over the phone, online or through an app if your supplier has one.
Digital meters will show five numbers in black and white, followed by one or more red numbers. The red numbers can be ignored.
Support for rising energy bills
The Government has pledged help for households this Winter. A discount of £400 will be applied to the gas and electricity bills of households across the country from October.
This will be automatic and people do not need to apply for it.
Around 29 million homes across England, Wales and Scotland will receive the new support.
Experts such as Mr Lewis however have warned that this will not go far enough, and the figure has not been revised since May, with prices changing dramatically since then.
