Energy Minister Charles Hendry has asked the Office of Fair Trading to bring forward a study in to the domestic heating oil and off-grid energy market.

In a written statement to Parliament, prompted partly by recent concerns raised over the rising costs of heating oil and difficulties attaining supplies, Hendry said that he recognised the "difficulties people have experienced".

Hendry said: "The recent severe weather has caused significant concern about the domestic oil market and the liquefied petroleum gas market. I fully recognise the difficulties people have experienced with rising prices and supply problems.

"Underlying many of the complaints are concerns about the challenges of supplying oil and gas to rural communities and whether the current market structure provides the reassurance that consumers can get fuels for heating when needed at a price they can afford.

"The OFT is currently consulting on its annual plan to help determine its work programme for 2011/12. This includes proposals to prioritise markets impacted by high, rising and volatile commodity prices. The off-gas grid energy market is clearly one such affected market.

"In response to the OFT consultation and mindful of the various issues highlighted by the recent severe weather, I have written to the OFT asking it to bring forward its competition and consumer study into off-grid energy.

"In addition, I have asked the OFT if the study could explore the longer-term consumer issues such as lifetime payback, consumer standards and labelling for alternative energy sources or supplies. Such a study would provide an independent assessment of the off-grid market and establish what further action may be necessary to ensure it works properly.

"I welcome the OFT’s support for this area, and look forward to seeing its conclusions in advance of next winter so the lessons from this winter can be learned and any necessary changes made."
