Energy regulator Ofgem has announced rules to limit tariffs to four simpler options, but what customers really care about is the cost.
As temperatures plummet there is concern over energy supplies. The amount of gas in storage has been run down as homes turn up the heating.
Despite environmental concerns the Government have given the green light for fracking to resume across the UK.
Scottish Energy Minister Fergus Ewing said he welcomed the UK Government view that there is a long-term future for the industry.
He said that the UK strategy highlighted oil and gas as an "enormous economic resource for decades to come.".
Scotland's Oil and Gas Strategy, developed in conjunction with industry, lays out a plan to help the industry go from strength to strength, and rising capital investment - predicting that investment should rise from £11.4 billion in 2012 to over £13 billion in 2013 - clearly demonstrates the confidence investors and the industry have in Scotland

The Scottish Government has already launched its industry led Oil and Gas strategy and is implementing a range of measures to support the industry in this time of major investment. We welcome the UK Government's commitment to work with the Scottish Government in implementing its strategy.
At an announcement on the UK's oil and gas strategy in Aberdeen today, Business Secretary Vince Cable is expected to say:
"I want us to consider what barriers are stopping British companies bidding for and winning work in the North Sea.
"This is an expanding industry.
"We can either help create more jobs and opportunities across the UK if we get this right, or see work going overseas if not."
The Government will today announce an oil and gas strategy that aims to secure thousands of jobs and billions of pounds of investment.
Plans for "tax certainty", skills development and supply chain support will be discused by three secretaries of state in Aberdeen, the oil capital of Europe.
Business Secretary Vince Cable, Scottish Secretary Michael Moore and Energy Secretary Ed Davey will speak to business leaders about the strategy this morning.
Britain faces the prospect of gas rationing for the first time, experts have warned.
Energy expert Ann Robinson told the Independent: “If this dreadful weather continues for the next two or three weeks we should be very worried, because if we get into a position where we do run out of gas there is not a lot that can be done in the short term."
The Government has denied the UK is on the brink of running out of gas following weeks of unusually cold weather.
It had been reported that there were only two days' worth of gas left in reserve as a result of the cold snap, with gas stocks 10% full, compared to 49% this time last year.
But a Department of Energy and Climate Change (DECC) spokeswoman said: "Protracted cold weather increases demand but the UK gas market is responsive and our gas needs are continuing to be met.
"Gas storage would never be the sole source of gas meeting our needs, so it is misleading to talk purely about how many days' supply is in storage."
She said that while half of the nation's gas needs were supplied from the North Sea, there were also pipelines from Norway and elsewhere in Europe, shipments of liquefied natural gas and storage.
The Times (£) is reporting that the recent cold snap has left Britain drained of nearly its gas supplies, sparking fears of a spike in energy prices.
Households have been forced to turn up their heating as the freezing weather continues, pushing the demand for gas to 20% higher than normal in March, the paper claims.
Last night gas stocks were just 10% full, compared to 49% this time last year, it said.
Energy prices will soar if Britain is forced to make up the shortfall by importing more liquefied natural gas from elsewhere, an energy expert warned.He said that Britain would struggle to cope if a technical problem caused a North Sea gas field to shut down.
Andrew Horstead of the energy consultancy Utilyx told The Times: "There is immense pressure on the existing infrastructure."We are almost maxed out from imports through pipelines. The big concern is that there is very little flexibility left in the system."
It comes as the head of the energy giant SSE warned of the "very real risk" of the lights going out in Britain.
The head of the energy giant SSE warned of the "very real risk" of the lights going out in Britain.
Ian Marchant said the Government was underestimating the problem, as he announced plans to cut back on power generation at five sites because the stations are either uneconomic or coming to the end of their lives.
It appears the Government is significantly underestimating the scale of the capacity crunch facing the UK in the next three years and there is a very real risk of the lights going out as a result.
He said the energy watchdog Ofgem had recently expressed real concern about the tightening of the UK's generation capacity margin that would follow expected plant closures in the next few years, predicting a 1:12 chance of the lights going out.
It is unlikely that the majority of the reductions in generation capacity and the delays to new investment we have announced today will have been included in this analysis, which highlights that the situation is likely to be even more critical than even they have predicted.
- Fit an audible carbon monoxide alarm: They need to be put in a central location in the house and can be fixed to the wall or can be placed on a table, bookshelf or shelf.
- Have fuel-burning appliances serviced annually by an appropriately qualified and registered engineer.
- Don't block ventilation and have chimneys swept at least once a year.
- Know the main symptoms: headaches, dizziness, nausea, breathlessness, collapsing and loss of consciousness.
- Keys signs are if symptoms clear up when you are away from home and come back when you return, or if other people in your household experience similar symptoms.
- Watch out for soot or yellow/brown staining on or around your appliance.

Jennie McAlpine, who plays Fiz in Coronation Street, has told The People that the current carbon monoxide storyline is "already saving lives."

Hopefully it will get people to check their boilers and get carbon monoxide monitors.
There are 4,000 people a year who are affected and 50 die every year from something that could be very easily eliminated.
I've been told by the people at the Gas Safety Register the publicity surrounding the plotline has saved lives already.
