12:03 Mr Osborne
Businesses also want a simpler tax system. I have asked Angela Knight and John Whiting at the Office of Tax Simplification to look at what more we can do to make the tax system work better for small firms and I am funding a dramatic improvement in the service that Her Majesty’s Revenue and Customs offers them. Many retailers have complained bitterly to me about the complexity of the carbon reduction commitment. It is not a commitment; it is a tax. I can tell the House that we are not going to reform it. Instead, I have decided to abolish it altogether. To make good the lost revenue, the climate change levy will rise from 2019. The most energy intensive industries, such as steel, remain completely protected, and I am extending the climate change agreements that help many others.
The Secretary of State for Energy and Climate Change and I are announcing £730 million in further auctions to back renewable technologies, and we are now inviting bids to help develop the next generation of small modular reactors. We are also going to help one of the most important and valued industries in our United Kingdom, which has been severely affected by global events. The oil and gas sector employs hundreds of thousands of people in Scotland and around our country. In my Budget a year ago, I made major reductions to its taxes but the oil price has continued to fall, so we need to act now for the long term. I am today cutting in half the supplementary charge on oil and gas from 20% to 10% and I am effectively abolishing petroleum revenue tax too, backing this key Scottish industry and supporting jobs right across Britain— [ Interruption. ]
