My hon. Friend is extremely astute: he has noted the significant contribution these taxes will make to the Exchequer. As I have just said, although this generous allowance is to ensure that we still encourage investment at a time when energy security is critical and where the long-term solution is having secure energy in this country, he is right to highlight the revenue being raised. After all, it goes a long way to funding the support that our constituents are receiving. In fact, they are receiving it this very week: payments are going out to support people facing these very high energy bills. The energy support guarantee this winter will save a typical household £900. We are putting in place extensive support, and as my hon. Friend says, a significant amount of that revenue comes from this new tax.
Putin’s barbaric illegal invasion of Ukraine and the utilisation of energy as a weapon of war has made it clear that we must become more energy self-sufficient.
That is why this Bill also ensures that the levy retains its investment allowance at the current value, allowing companies to continue claiming around £91 for every £100 of investment. This investment will support the economy and jobs while helping to protect the UK’s future energy security, and in future the Government will separately legislate to increase the tax relief available for investments which reduce carbon emissions when producing oil and gas, supporting the industry’s transition to lower-carbon oil and gas production. Together these measures will raise close to £20 billion more from the levy over the next six years. As my hon. Friend said, that brings total levy revenues to more than £40 billion over the same period—of course he added on top of that the electricity generators levy, which we will be consulting on. The Government are also taking forward measures to tax the extraordinary returns of electricity generators, as I have just said, but we will do so in a future Finance Bill to ensure that we can engage with industry on these important plans.
The autumn Finance Bill also introduces legislation to alter the rates of the R&D tax reliefs. Making those changes will help to reduce error and fraud in the system, ensuring that the taxpayer gets better value for money while continuing to support valuable research and development needed for long-term growth. Over the last 50 years, innovation has been responsible for about half of the UK’s productivity increases. That is an extremely important statistic. We all know the value of R&D to all of our constituencies—I look in particular at my hon. Friend the Member for South Cambridgeshire (Anthony Browne), who will know of its importance in our university cities and all of our key clusters. R&D is a key way of raising productivity, which is why we have protected our entire research budget and will increase public funding for R&D to £20 billion by 2024-25 as part of our mission to make the United Kingdom a science superpower. These measures are significant, but ultimately businesses will need to invest more in R&D. The UK’s R&D tax reliefs have an important role to play in doing that.
