Energyhelpline.com has launched its collective switching deals, which it says can save consumers £50 a year compared to the next best.
It says the average family switching from a standard tariff can save £335 a year on fuel bills.
The price comparison site's tariffs are available via its 'Huge Switch' initiative. Unlike other similar schemes, anyone can sign up, even if they've not previously registered an interest.
However, the top deals could go at any time if demand is too high. As things stand, they will definitely be pulled next Monday at 4pm, though Energyhelpline hopes this deadline can be extended.
What are the deals?
There are a variety of tariffs available under the scheme.
All are available on the open market. However, if you buy via the 'Huge Switch' you will also get cashback, which is where the big saving comes (see our Cheap Gas & Electricity guide for how to sign up).
The top five Huge Switch deals, with annual costs based on typical household usage for dual fuel customers, are:
'Huge Switch' deals
|Provider||Tariff name||Typical cost/yr||Cashback||Discounted cost/yr|
|First Utility||iSave v10 (variable)||£1,027||£40||£987|
|First Utility||iSave fixed v2 Sept 2013||£1,047||£50||£997|
|EDF||Blue+ Price Promise Sept 2013 (fixed)||£1,054||£50||£1,004|
|Scottish Power||Online Energy Saver 19 (variable)||£1,055||£30||£1,025|
|Sainsbury's||Online Price Freeze June 2013 (fixed)||£1,058||£15||£1,043|
Energyhelpline.com says First Utility's iSave v10 is the cheapest deal available from any supplier since September 2011.
Remember, headline energy prices are based on a typical user so actual costs can vary wildly depending on where you live and how much energy you use.
Mark Todd, director at Energyhelpline.com, says: "At a time of rising fuel bills, we are winding the clock back to 2011 prices, before average energy bills smashed through the £1,000 a year mark.
"We have taken a massive hit on our commission to get the energy suppliers on board and we are proud that so many have agreed to take part."
How does this compare to Which?'s 'Big Switch'?
Consumer lobby group Which? unveiled a similar initiative two weeks ago, with the cheapest deal being Co-operative Energy's dual fuel, fixed rate tariff costing £1,048 a year for a typical household paying by direct debit.
With cashback factored in, the top fix via the 'Huge Switch' costs £51 a year less.
None of the collective switching deals are available for pre-pay customers.
