Gas boiler ban: how to make sure everyone can afford low-carbon heating

Jul 2, 2021

Most of us only think about central heating when it stops working or when the fuel bills arrive. So reports of an impending ban on gas boilers in the UK – and news that green alternatives such as heat pumps can cost over £10,000 – might have been a nasty shock for many.


Most UK households rely on gas boilers, which are more efficient than ever, but still burn fossil fuels. As a result, domestic heating accounts for over a third of greenhouse gas emissions and almost half of energy consumption nationwide.


Tackling climate change means changing how we heat our homes. But this is possible without turning warmth and comfort into unaffordable luxuries. Our research has looked at how business models can break this trade-off between people and the planet. One involves reimagining heating as a service.


When buying a boiler, a customer typically pays someone to buy and install it. They then sign a contract with an energy company to provide the fuel and find another service provider to fix the boiler when it breaks down. Wouldn’t it be simpler to sign one contract with one company that could guarantee a steady supply of heat?


A manufacturer would be responsible for installing the heating system and for ensuring it works. Since the manufacturer would be paid for delivering heat, you wouldn’t be billed for repairs or have to pay steep upfront installation costs – you’d simply have to keep up with flat monthly payments. By aligning the objectives of all parties, “heat as a service” allows the risks and rewards of investing in new technologies like heat pumps to be shared.


Fuelling poverty


Low-carbon technologies such as heat pumps can go a long way to achieving net zero targets. Unlike a boiler, heat pumps move heat from warm to cold spaces rather than generate it, operating in a similar way to air conditioning.


Heat pumps run on electricity and can reduce greenhouse gas emissions if their power comes from low-carbon sources. Waste heat from sewage plants and other facilities can even be redirected to supply home central heating systems with the right infrastructure, such as district heat networks. But most UK homes have gas on tap, and new heating technologies are expensive to install and manage. Much of the required infrastructure needs to be funded.

Over two million households in England suffer from fuel poverty. This means that paying fuel bills would leave them with nothing left over for food and other necessities. More efficient, low-carbon heating can bring those bills down, but when faced with the decision to heat or eat, is it fair to expect people to invest in expensive technology? If these technologies are unaffordable, can we hope for the needed revolution in domestic heating?


The slow adoption of rooftop solar panels and electric cars demonstrates what a hard sell these technologies can be for cash-strapped consumers. Technology is not enough. Instead, we need to change the business logic for bringing technology into our homes.


Heat as a service


Digital technology has made it easier for almost everything we use, from music to cars and clothing, to be delivered as a service. Record stores selling albums now compete with online streaming services which offer a vast library of music ready to be played with a monthly subscription. Taxi drivers and car dealers have had to adjust to ride-sharing services and even fast-fashion companies are now threatened by online rental services, which help old clothes find new purpose.


Businesses offer software as a service and even manufacturing as a service, which take away the need for upfront investment and unexpected bills and allow customers to access and pay for what they need with a single fee or subscription. Heat as a service does something similar by cutting out the complexity of installing, maintaining and fuelling a boiler or heat pump.


In the winter of 2017, over 100 UK homes were offered a heat plan, which guaranteed an indoor temperature for an arranged monthly fee. Customers often struggle to keep track of how much they spend on heating, so the plan offered some peace of mind. The trial involved collaboration between local authorities, an energy company and a boiler manufacturer, plus digital tool providers that helped monitor and control the temperature. Most participants found they were more comfortable and were more likely to consider low-carbon heating on its own, and particularly as part of an arrangement like heat as a service.


Paying for heating technologies that are kinder to the planet is likely to be too expensive for lots of people. Relying on households to make these preparations on their own would also be disastrous for decarbonisation. A recent report by the International Energy Agency forecasted that less than 5% of the total emissions reductions needed to reach net zero by 2050 can be expected to come from such behaviour changes among the general public. Rather than expecting households to buy heat pumps, states and energy utilities should offer them low-carbon heating as a service.

New research partnership to develop biodegradable gloves from food waste for healthcare sector

Knowledge Transfer Partnership between Aston University and PFE Medical to develop a biodegradable clinical glove from food waste The gloves will provide a low-cost, convenient and sustainable alternative to the 1.4bn disposable gloves used in the NHS each year The innovation will reduce clinical waste and costs and help the NHS reach its net zero goals. Aston University and Midlands-based company PFE Medical are teaming up to create biodegradable gloves made from food waste for use in the NHS. They will offer a low-cost, convenient alternative to disposable gloves without compromising patient safety. More than 1.4bn disposable gloves are used by the NHS each year. They create large volumes of clinical waste which has both an environmental and economic cost. The Knowledge Transfer Partnership (KTP) project will develop a more sustainable alternative made from polymers derived from food waste such as orange peel, able to degrade naturally. The gloves will initially be for use during low-risk tasks such as ultrasound scans, rather than in more critical situations such as operating theatres. The gloves would be designed to not only reduce clinical waste and costs in the NHS, but also carbon emissions, helping the NHS reach its goal to be the world’s first net-zero health service. With most personal protective equipment (PPE) currently sourced from Chinese manufacturers, the goal is to develop a biodegradable glove that can be manufactured using a UK supply chain. The challenging project draws on Aston University’s expertise in sustainable polymer chemistry, centred at Aston Institute for Membrane Excellence (AIME). Aston University has one of the largest research groups of polymer chemists in the UK. The project will be led at the University by Professor Paul Topham, director of AIME, and Dr James Wilson, AIME associate member. The research team have chosen to focus on polymers from food waste in order to ensure that the final product can be manufactured sustainably. Most polymers are currently made from petroleum. Polymers made from food waste, ranging from fruit waste to corn or dairy products, have the potential for antioxidant and antibacterial properties if designed appropriately. The team will manipulate the polymer molecules so that they include the right monomers (the smaller units which make up the molecules) in the right location to achieve the properties they require. Critical to the success of the project will be PFE Medical’s commercial and clinical experience of taking new innovations into medical use. It will be the third KTP between Aston University and PFE, following on from successful projects to develop an automated endoscope cleaner, now in use across University Hospitals Birmingham NHS Foundation Trust (UHB). Professor Topham said: “At Aston University, we have a long history of working with industry, of translating fundamental research into solutions for real world problems. This project with PFE Medical provides us with that route, to take our science and engineering and make a difference to peoples’ lives. That’s exactly where, as researchers, we want to be.” Rob Hartley, CEO of PFE Medical, said: “Our previous KTP with Aston University was a phenomenal success, thanks to the brilliant team we had on board. I’m just as excited by this project, which is looking to solve an equally long-standing problem. If we can achieve our goal, then the implications are huge, going far beyond the NHS to all the other situations where people are wearing disposable gloves.” KTPs, funded by Innovate UK, are collaborations between a business, a university and a highly qualified research associate. The UK-wide programme helps businesses to improve their competitiveness and productivity through the better use of knowledge, technology and skills. Aston University is a sector-leading KTP provider, ranked first for project quality, and joint first for the volume of active projects.

Aston University’s Professor Gina Rippon wins British Psychological Society book award for The Lost Girls of Autism

Gina Rippon, professor emeritus of cognitive neuroimaging at Aston University, has won an award for her book, The Lost Girls of Autism The book won the 2025 British Psychological Society Popular Science Award It explores the emerging science of female autism, and examines why it has been systematically ignored and misunderstood for so long. The Lost Girls of Autism, the latest book from Gina Rippon, professor emeritus of cognitive neuroimaging at Aston University Institute of Health and Neurodevelopment (IHN), has won the 2025 British Psychological Society (BPS) Popular Science Award. The annual BPS Book Awards recognise exceptional published works in the field of psychology. There are four categories – popular science, textbook, academic monograph and practitioner text. With the subtitle ‘How Science Failed Autistic Women and the New Research that’s Changing the Story’, The Lost Girls of Autism explores the emerging science of female autism, and examines why it has been systematically ignored and misunderstood for so long. Historically, clinicians believed that autism was a male condition, and simply did not look for it in girls and women. This has meant that autistic girls visiting a doctor have been misdiagnosed with anxiety, depression or personality disorders, or are missed altogether. Many women only discover they have the condition when they are much older. Professor Rippon said: “It's such a pleasure and an honour to receive this award from the BPS. It’s obviously flattering to join the great company of previous winners, but I’m also extremely grateful for the attention drawn to the issues raised in the book. “Over many decades, due to autism’s ‘male spotlight’ problem, autistic girls and women have been overlooked, deprived of the help they needed, and even denied access to the very research studies that could widen our understanding of autism. This book tells the stories of these girls and women, and I’m thrilled to accept this prize on their behalf.”

New book from Aston University academic shows that Christmas tasks mostly fall on women

New book by Dr Emily Christopher shows differences in how household tasks are divided by men and women Book highlights that women tend to buy the Christmas presents and send cards Men often see women as being more thoughtful or having better knowledge of what people would like. A new book from Aston University’s Dr Emily Christopher reveals that when it comes to sending Christmas cards and buying Christmas presents, women are still mostly doing the work as they are perceived to have better knowledge of what people would like. Dr Emily Christopher, a lecturer in sociology and policy at Aston School of Law and Social Sciences, has recently published her book Couples at Work: Negotiating Paid Employment, Housework and Childcare, which look at how household tasks are divided by men and women and the reasons behind these divisions. The data for the book has been collated over an eight-year period with couples being interviewed twice to provide a robust set of results. It looks at how different sex parent couples combined paid work, housework and childcare. The research revealed how gender norms continue to shape how certain daily household jobs are divided. Women were more likely than men to clean the house, especially bathrooms, wash clothes and put clothes away. Men still tend to do tasks like mowing the lawn and DIY but now are also more likely to do the cooking and the grocery shopping. The research shows that the key to understanding how household tasks are divided lies in the meaning they hold for partners. With the festive season upon us, the book reveals that woman are largely responsible for the Christmas present buying and sending cards with 100% of those taking part in the research saying that women mostly carried out these tasks. This also included buying for the male partner's relatives. In instances where men had a 'helping' role in these tasks, this included being involved in the discussion or consulting on choice of presents, especially for children, with only a small minority buying presents for their own family. The data revealed that where women didn't choose and buy presents for their partners family, they were still involved in reminding their partners that this needed to be done or advising on choice of gifts, showing that women were still taking on the mental load of planning for the festive season. The book reveals that when men were questioned about why they didn't get involved in present buying, they drew on gender norms. Women were often described, by the men, as being more thoughtful or having better knowledge of what people would like. Men often described how family members wouldn’t receive presents at all if it relied on them. Although much of the gift giving and organising represented love and affection for the women, which many found enjoyable, many still saw it as work and expressed that they would like their partners' to be more involved. Dr Christopher said: “This book takes an in-depth look at the way in which everyday roles around the household are divided between men and women. “The research shows that over a period of eight years fathers increased their role in childcare tasks but this did not always extend to housework. “The pandemic was an opportunity to change how couples share housework but women were still more likely to carry out tasks like cleaning, washing clothes and putting clothes away and overwhelmingly remained responsible for the mental orchestration of family work.”
