Net Zero Transition: Consumer-led Flexibility

Martin Vickers Excerpts

Tuesday 9th December 2025 Westminster Hall

[Claire Young]

I absolutely agree, and I am coming to those points.

The Government have set out a clean flexibility road map, and E.ON has found that 84% of people want more control over energy, so what is the catch? It might be said that this is all well and good for affluent consumers, who can afford the smart technology—the electric cars, battery storage and heat pumps, and the washing machines and dishwashers with timers so that they do not have to get up in the middle of the night to switch them on. It is all right for those who are digitally literate and for those who have heard of smart tariffs—let alone got their head around how they work. What about those who do not fit into those privileged categories? How does consumer-led flexibility fit with a just transition?

A report by the MCS Foundation in August found that 78% of people are unaware of schemes that reward households for reducing energy use at certain times and 41% are unlikely to switch to tariffs offering cheaper electricity outside peak times. If only a privileged few can access flexibility, will it deliver the potential benefits or simply place more of a burden on those already struggling to pay? It has the potential to lower all bills—as previously mentioned—by driving costs out of the system. That benefits even those who cannot participate. But we need to do more. To achieve the scale of change necessary, we need more action from the Government.

About three in 10 homes still do not even have smart meters, and the Government concede that, in those that do, one in 10 is faulty, while others put the figure even higher. That does not bode well for the roll-out of more advanced smart technology. What about the digitally excluded? The Government should oblige energy suppliers to engage with digitally excluded groups and those on low incomes on the benefits of flexibility. Does it not make comparing tariffs more complicated? Potentially it does, so why not support a “try it and see” approach by requiring energy suppliers to offer risk-free trial periods for time-of-use tariffs?

We have all seen, in other periods of rapid technological change, that some projects fail, so Ofgem needs to strengthen consumer protection, with clear redress powers if that happens. The Government’s own clean power action plan says that to reach clean power 2030, we need 12 GW of consumer-led flexibility—more than nuclear, hydrogen and carbon capture combined. But flexibility gets none of the coverage that those technologies do. It is all very well having a road map. What are Ministers actually doing to change the fact that nearly four in five people do not even know that they can be rewarded for changing when they use electricity?

The markets have been designed for the traditional fossil fuel generators, not for individuals and businesses that generate their own power or can offer storage. We need a presumption of openness in energy market design and rules to support them. If a rule from a market maker prevents a family with a battery, or a business with thermal storage, from participating in the market, it should be forced to justify why. The way that the network costs and final consumption levies work means that consumers cannot currently be paid to use excess renewable power when electricity prices go negative. That needs urgent reform. Imagine how much easier it would be to make the case for the clean energy transition if people could be paid for using clean, free power.

If flexibility is to be delivered, there needs to be clear accountability, without room for buck passing between the Department for Energy Security and Net Zero, Ofgem and the National Energy System Operator. The new flexibility commissioner needs to be given teeth, the ability to demand transparency and accountability from everybody involved, and the authority to call out failure. Have Ministers looked closely at the industry progress board that has been set up, and can the commissioner work with it?

It is time to give people the chance to take control and be active participants in our energy system, rather than being at its mercy. The road map, the commissioner and the technology are all in place, and we know that the public want more control over their energy and their bills. Will the Government take the extra steps needed to make this happen, or will they allow the dinosaurs of the old system to stand in the way? Let us move beyond the map to make this a reality and slash bills for everyone.

I remind Members that they should bob if they wish to be called during the debate.

--- Later in debate ---

[The Minister for Energy (Michael Shanks)]

It is a pleasure to serve under you today, Mr Vickers. I am frequently told that consumer-led flexibility does not get enough time, but I now have almost an hour to talk about the Government’s plans on it. I intend to use every moment I have.

[Martin Vickers (in the Chair)]

You don’t have to!

[Michael Shanks]

No, I don’t intend to—do not worry, colleagues.

This is an important debate, however, and I thank the hon. Member for Thornbury and Yate (Claire Young) for securing it. She made a point that those in the industry make regularly to me: that this is too often a footnote in the discussion about achieving our future energy security. It should not be. It should be much further up the agenda. It is not for want of trying; I often talk about it, but it is regularly the bit that gets cut out of interviews before they are broadcast. The Government are certainly talking about these issues.

The hon. Lady outlined perfectly the problem of how we get cheaper, more secure power to homes and businesses, and the three fixes: building more grid, strategically planning where energy is built in the first place, and utilising flexibility. The truth is that we need to do all three at a pace never before seen in this country. I will come back to those points, but I welcome her recognition of them.

My hon. Friend the Member for Washington and Gateshead South (Mrs Hodgson) made a fantastic speech, as always. She is a fantastic champion for the north-east and a long-standing campaigner on the issue of how we can reduce fuel poverty. She made the point that we risk losing the opportunity of getting cheaper power to people’s homes and bringing down their bills, and she mentioned the fantastic innovations out there already. I have had the pleasure of seeing a number of them. When I visited the Mining Remediation Authority recently, I had the genuine pleasure of hearing about the mine water heating scheme. That is a fantastic example of how we can utilise something that we used decades ago to power the country. There is also a social justice argument, as those communities who still have deep scars from that period can benefit from cheaper bills in the long run.

I also want to recognise the point the hon. Member for Thornbury and Yate made about the equality aspect and how we will bring everyone with us on this transition. I will return to that point, but first I want to return to first principles and say why the Government are committed to delivering clean power by 2030. At the heart of that mission is an energy system that delivers flexibility for consumers: not forcing consumers to make choices, but giving them the opportunity to make choices that bring their bills down, and to use technology for the betterment of their lives in a way they choose.

The clean power action plan outlined 10 GW to 12 GW of consumer-led flexibility. I think that in the months ahead we will be talking much more about that part of the action plan. The Government have had to move very quickly in the first 16 months to deliver on the auctions in offshore and onshore wind, to lift the ban on onshore wind and to deliver much more solar than we have ever seen, but flexibility has been hugely important in the background, and we will say much more in public about it in the coming months.

Let me respond briefly to the core argument that the shadow Minister, the hon. Member for Mid Buckinghamshire (Greg Smith), made about the clean power mission:

“The UK is a world leader in renewable energy…and we must go further. Energy security means national security. We must replace imported fossil fuels with cheaper, cleaner, domestic sources of energy. That is how we will ensure that the UK never again suffers the rising prices caused by Putin’s weaponisation of energy following his invasion of Ukraine.”—[Official Report, 22 November 2023; Vol. 741, c. 21WS.]

Those are not my words, but the words of the shadow Secretary of State, the right hon. Member for East Surrey (Claire Coutinho), in November 2023. I am not quite sure what has happened to the Conservative party in two years, but the Conservatives seem to have completely changed not just their position, but their understanding of the facts and science behind what they were saying then. The right hon. Member, who was Secretary of State at the time, made my argument just as well as I could ever seek to. I will leave it at that.

A just transition has the power to unlock enormous benefits for people right across the country. It is why we have pledged to deliver clean power, because we know it is cheaper and it removes the volatility of which all our constituents are still facing the cost. It will shield consumers from the volatility in global gas prices, over which we have absolutely no control, but it will also create new jobs in industries right across the country. It is the economic opportunity of the 21st century.

The role of storage will be important. The hon. Member for Newton Abbot (Martin Wrigley) talked about a school trip to Dinorwig; in Scotland, I think every single school child went to Cruachan, the hollow mountain, which is another pumped hydro power station. Although pumped hydro may be a technology from the last century, it is critical in this century as well. Indeed, the Government have launched the first new long-duration energy storage in 40 years. It is a critical way of dispatching clean power and storing it for when we absolutely need it, so it still plays an important role.

Consumer-led flexibility will play an important role in getting renewable energy to people’s homes. It will help us to balance the grid and ensure that we have supply when we need it. It enables us to take advantage of low-carbon energy and reduce periods of peak demand and the associated infrastructure needs. It also involves financial rewards for those who choose to shift their electricity use to times when supply is more abundant, cheaper and cleaner. Smart meters are a key part of that. As we all know from our constituencies, we would all have liked to see a more efficient roll-out of the smart meter programme over the years, but 70% of meters across Great Britain are now smart or advanced meters, with more than 40 million homes and businesses having them installed.

We will continue to monitor the roll-out in Government very closely. Indeed, I chair a working group that is looking at how we can deliver market-wide half-hourly settlements much faster. That is really important so that consumers and businesses benefit directly from having a smart meter and new technology.

[Michael Shanks]

I will come to the hon. Gentleman’s point. I always appreciate the kindness of his contributions, although he needs to lower his expectations of mine. He rightly mentioned the statistic that 68% of households in Northern Ireland have oil heating, which he raised with me in a previous debate. That figure surprised me, and it is a reminder of the complexity of the different circumstances across the United Kingdom of Great Britain and Northern Ireland. I work closely on this issue with Northern Ireland Executive colleagues in the Department for the Economy, and we share much of our good practice to make sure that everybody comes with us on this journey. I will shortly say more on the hon. Gentleman’s point about gas.

We are already seeing consumers benefiting from flexibility. Last year, the demand flexibility service saw over 2 million households and businesses save money by flexing their demand. We are committed to ensuring that all consumers have the option to participate, not just those who can afford certain technologies. The Government have committed £1.5 billion through the warm homes plan, which will help to upgrade low-income households. The Government will also work to ensure that flexibility is simplified and accessible for all consumers who want to take part, not just the tech savvy and those who are already able to. We have to remember that flexibility brings down the price for everyone, even those who are not participating, because of the benefits it brings to the overall system.

As we shift away from gas, consumer-led flexibility will become even more vital for managing an electrified system. Crucially, it will bring down bills for all consumers, not just those who actively participate. The Liberal Democrat spokesperson, the hon. Member for Newton Abbot, gave a figure on the direct benefit from consumer-led flex, and a more flexible system is estimated to save up to £10 billion a year overall because of that efficiency. It is hugely important.

The hon. Member for Strangford (Jim Shannon) asked about the transition. Obviously, connecting to the gas network is difficult in Northern Ireland, and this is a huge opportunity for many households to jump a step—from oil heating to heat pumps and other technologies. There is a real opportunity for those households to benefit, perhaps even more than some other households, if we get the transition to consumer-led flex correct. I look forward to more conversations with the hon. Gentleman on that issue.

The other point I want to make is about the role of technology. Consumer-led flexibility is becoming increasingly automated, which means that consumers can benefit from these opportunities with little or no intrusion in their daily lives. Indeed, I have seen examples where consumers have set up technology and let it run for months at a time. For example, an EV owner can plug their car into a smart charger, which will optimise charging so that it happens at the most cost-effective times of the day, while still meeting the battery charge they need the next morning, saving a significant amount of money.

I recently had a great opportunity to visit Flexitricity in Edinburgh, which is a fantastic business—not least because it has a fantastic view of Edinburgh castle, although that was not my reason for visiting. My visit brought home two things: first, the cutting-edge technology and innovation that we already have in this space; and secondly, how this is an opportunity to create high-paid, skilled jobs across the country. I met a number of apprentices and people who had changed career to be part of that innovation—the business is a fantastic example. I thank the Association for Decentralised Energy, some of whom I see in the Public Gallery today, for joining me on that visit and for the work they do.

We recently published the flexibility road map, which sets out specific, measurable actions for DESNZ, Ofgem and NESO to deliver the flexibility we need. The road map sets out a strategy and clear actions to make sure we can deliver on this. It acknowledges that the Government, in partnership with Ofgem and NESO, will need to take a leading role in making sure this is a priority for those organisations. The publication puts consumers at the heart of what we want to achieve.

The road map is a first step. To deliver it, we know we have to sustain that momentum. As many hon. Members have said, agreeing that this is the right thing to do is not enough; we have to get on with delivery. This debate is perfectly timed, because this afternoon I will attend the first clean flexibility road map quarterly forum to make sure we are driving progress on this. That was already in the diary, but this debate is perfect timing.

I thank the ADE for all its engagement and expertise on this matter, and I thank all the organisations working in this space for raising innovative and creative ideas for how we can make this happen faster. This is an area where the Government do not always know best, and the innovation from the private sector and communities across the country will help us to deliver this transition. It is crucial that the Government continue to hear that, and that we continue to be challenged to move further and faster.

We have seen good progress on leadership, which goes hand in hand with our work on the road map and on the appointment of a flexibility commissioner. We will be able to announce who we are appointing very soon, and they can then get on with driving this work forward as part of the clean power mission. Leadership is important more generally in this space. As politics moves away from a fact-based, rational discussion of the challenges this country faces, it is ever more important that we have these debates on the detail of how we deliver such important policies.

We must also recognise that we are making progress. There is sometimes a tendency to think that nothing is happening, but a huge amount is happening: the migration of consumers to half-hourly settlement has begun and is making great progress; NESO is about to consult on the next iteration of the demand flexibility service; Ofgem is assessing how to recover costs through bills in a way that is fair and efficient; and we have consulted on our smart secure electricity systems programme, including how we can make it easier for electricity consumers to participate. All that work going on in the background will start to have a real impact on people’s lives in the coming months.

I thank everyone for their contributions to this debate. The Government are committed to delivering a clean power system, because that is the only way to bring down people’s bills in the long run, to remove the volatility of fossil fuels, for which we are paying the fossil fuel penalty, and to deliver energy security in an increasingly uncertain world. Flexibility is at the heart of this, and for us to have a genuinely just transition—one that brings people with us—we have to do what is challenging. This is a new way of working. It is different, and it will require people to think differently about their energy use and about how we deliver the change as a country, but opportunity is right at the heart of this—we should never forget that opportunity is the prize if we achieve this.

We will continue to work across Government and across the energy sector so that people can take advantage of the benefits of consumer-led flexibility and so that, ultimately, we end up with a 21st-century energy system that recognises that all our lives have changed in the last few years in how we consume electricity. Every single projection suggests consumption will increase over the coming years, so it is hugely important that we take these steps now so that the people of this country benefit from the energy transition that is under way.

I thank everyone again, and I thank the hon. Member for Thornbury and Yate for securing this important debate.

[Martin Vickers (in the Chair)]

I thank the Minister for not taking the full 50 minutes available, which leaves more than the usual two minutes for Claire Young to wind up.
