Regulatory policies to generate sufficient demand for clean heating and energy efficiency
Meeting Scotland’s climate change targets will require a significant increase in the uptake of low carbon heating and energy efficiency across the country’s homes. The Climate Change Committee (CCC) has made it clear that transforming how we heat our homes is essential to meeting Scotland’s climate change targets.
Their advice, which will inform the development of Scotland’s Climate Change Plan, highlights that emissions reductions from buildings will be the second largest contributor to meeting the first two carbon budgets (2026-2030 and 2031-2035), accounting for 19% of total emissions reductions.
To achieve this, the CCC recommends that by 2035:
- 40% of existing homes should be using low-carbon electric heating – primarily heat pumps -rising to 92% by 2045.
- Annual heat pump installations should reach nearly 35,000 by 2030 – in comparison, 7,660 MCS-certified heat pumps were installed in Scotland in 2023/24.
- Alongside this, improving energy efficiency is expected to contribute 14% of the emissions needed by 2035.
- This scale of transformation will not happen without strong policy intervention. Clear regulatory signals are needed to drive demand and give certainty to households, businesses and the supply chain.
While the Scottish Government has proposals for what will go into the Heat in Buildings Bill, several key regulatory proposals from the original consultation have been dropped or weakened. These include:
- The removal of point-of-sale trigger that would have required property buyers to replace polluting heating system within a set period.
- Replacing a requirement for homeowners to replace fossil fuel heating systems by 2045 with a broader government target.
- Replacing the proposal to introduce minimum energy efficiency standards for owner occupied homes with a provision allowing Ministers to bring in such standards later through secondary legislation, following further consultation.
- Removing proposed powers for local authorities (and Scottish Ministers) to require buildings in Heat Network Zones to end their use of polluting heating systems within a set timeframe once a heat network becomes available.
We supported all of these proposals and continues to do so. In addition, we recommended additional triggers be included to ensure clean heating systems are installed at other natural trigger points, including:
- When a polluting heating system comes to the end of its life.
- At point of major renovation to the property.
- At point of change of tenancy in relation to business premises.
- At point of any application for change of use of business premises.
If stronger regulatory policies on heating and energy efficiency are not included in the final Heat in Buildings Bill, it will be essential that the Climate Change Plan commits to publishing a clear regulatory roadmap – outlining how and when future decisions will be made – to provide certainty and support the transition to clean heat and improved building performance.
Support for the supply chain
Meeting Scotland’s climate change targets will require tens of thousands of low carbon heating and energy efficiency measures to be installed each year. That means that there will need to be sufficient numbers of trained professionals to carry out these installations. This will require a significant increase in workforce capacity, particularly in remote and rural areas where access to skilled installers can be more limited. To support this, policies are required that support supply chain growth, including:
- Provide policy certainty. The Scottish Government should set out clear, long-term plans and funding commitments for retrofit programmes. This should include clarity on what measures will be needed, how much work is expected, when it will happen, and where – so that businesses can plan ahead and invest in workforce growth. Regulation will also be important to provide certainty for businesses. At present, uncertainty about future demand is holding back supply chain investment.
- Support streamlined upskilling and retraining. Modern apprenticeships can take up to four years to complete, creating a time lag in delivering skilled workers. The Scottish Government should support faster training routes – such as conversion courses for people entering from other sectors – to help meet immediate demand.
- Provide financial support for people reskilling. Introduce financial assistance for individuals undertaking training or changing careers into the retrofit sector. This would help remove income barriers during the training period and encourage more people to enter the sector.
- Make it easier for young people to start careers in retrofit. The Scottish Government should work with partners such as the Scottish College Network and SNIPEF to expand modern apprenticeship pathways in renewables. This will help young people gain the skills they need to access secure, long-term jobs in the retrofit sector.
- Raise awareness and improve the sector’s appeal. The Scottish Government should launch targeted campaigns to raise awareness of retrofit careers, particularly among underrepresented groups such as women and ethnic minorities. A lack of visibility is currently limiting workforce growth.
- Promote retrofit careers in schools. Collaborate with careers services to raise awareness of retrofit as a career option among school pupils. Early engagement will help young people make informed choices and enter the sector through supported pathways.
- Support SME installers to grow with local markets. The Scottish Government should continue to provide tailored support to help local SME installers expand in response to growing demand – especially in rural areas. Programmes like the Scottish Government’s Green Heat Installer Programme (GHIEP), which is delivered by us, already play an important role in this space and should be built upon.
- Support small businesses to take on apprentices. The Scottish Government should provide targeted financial assistance to help small and micro businesses cover the costs of employing apprentices. Many small firms – particularly in rural areas – are currently unable to afford the costs of taking on new apprentices. Supporting these businesses to take on apprentices would help grow the skilled workforce in the medium term and ensure that retrofit jobs are distributed across Scotland’s communities.
Awareness raising
The Scottish Government already delivers a wide-ranging public engagement programme though initiatives such as Scotland’s Climate Week and the Let’s Do Net Zero Campaign, as well as other engagement and awareness activity.
However, while most people are concerned about climate change, many do not understand what they can do to reduce their own impact. In addition, the UK public do not feel part of the transition, with a recent survey of UK homeowners finding that 48% of respondents felt that the net zero transition was happening to them and over a third felt they could not engage with it at all.
Across Great Britain, public knowledge of energy efficiency and low carbon technologies also remains low. Recent research found inaccurate beliefs and poor knowledge to be widespread amongs those surveyed. For example, 73% of British consumers surveyed stated they don’t understand what a heat pump is and 57% believed home insultation doesn’t work well in older homes.
Misinformation and negative stories also contribute to scepticism and a lack of trust around low carbon technologies, acting as a barrier to action. Recent Consumer Scotland research highlights the value of clear, trusted information and better signposting to impartial sources like Home Energy Scotland to help consumers make confident decisions.
To secure public buy-in and ensure the success of decarbonisation policies, it will be important to maintain and build on existing engagement activity. Public engagement helps create the conditions for policy delivery by building public understanding and support – both of which are essential for introducing the policies needed to drive action on the ground.
Continue to provide access to impartial, tailored advice
To make informed decisions about improving the energy performance of their homes people need access to trusted advice. The Scottish Government’s Home Energy Scotland advice service plays a central role in meeting this need, offering free impartial advice to consumers on fuel poverty, energy and carbon-saving advice which is tailored to their individual circumstances.
Its advice aims to facilitate informed choices by removing technical jargon, making home improvements simple to understand, changing the buying and usage behaviours of householders and referring them to financial support schemes that best meet their needs. As demand for energy efficiency and clean heating grows, it will be important to continue building on Home Energy Scotland’s capacity to give households the confidence to make changes to their homes.
Continue to ensure that there is a financial offering for all
To meet Scotland’s carbon budgets and ensure a fair transition to clean heating, it is essential that financial support for clean heating and energy efficiency measures – including grants and subsidised finance – remains in place.
For heat pumps, financial support will need to remain in place until cost parity is achieved between owning and running a fossil fuel boiler and a heat pump. At current prices, the upfront costs of heat pumps are higher than fossil fuel boilers and without adequate financial support many households will struggle to afford the switch.
While banks and other lenders may increasingly offer loans or other green finance products to support this transition, not all households will be eligible for such finance. The Scottish Government will therefore need to continue providing subsidised finance and grants to ensure that everyone – including those excluded from mainstream credit markets – can access the support they need. For fuel poor households, fully funded measures will be essential.
Maintaining a financial offering is critical not only to support uptake and meet installation targets, but also to ensure fairness and avoid penalising those unable to access private finance.
We therefore think that the following policies are necessary if climate budgets are to be met:
- Maintain public financial support for clean heating until cost parity is achieved between installing and running fossil fuel boilers and heat pumps.
- Provide fully funded measures for fuel-poor households to ensure equitable access to clean heating and energy efficiency.
- Facilitate the development of private finance options to complement public support and expand consumer choice.
- Provide a clear roadmap for the evolution of financial support over time, offering certainty to households and the supply chain.
Recognising overheating as part of the heat transition
As Scotland’s climate continues to change and rising temperatures increase the risk of overheating in homes, it will be important to ensure that cooling is considered as part of the clean heat transition – both to protect health and wellbeing and to avoid unnecessary increases in energy use, emissions and household costs.
Policy should prioritise passive cooling measures such as effective shading and natural ventilation. These approaches can often reduce or eliminate the need for mechanical cooling, helping households stay comfortable without driving up energy demand or costs. However, without clear guidance, there is a risk that households will default to energy-intensive solutions like standalone air conditioning units – when simpler, lower cost options would suffice.
There is also a risk that households will adopt fragmented and inefficient solutions – for example, installing a heat pump for heating and later adding a standalone air conditioning unit which would increase both energy demand and household costs more than would have been the case if cooling needs had been considered from the outset.
For some households, the ability to cool as well as heat may actually be a driver for adopting heat pump technology – particularly air to air or bidirectional systems. Recognising this potential could help broaden the appeal of clean heating solutions and support uptake, especially in homes where overheating risk is already a concern.
To date, public funding and incentives have so far focused primarily on heating. However, as overheating risks increase, there may be a case for revisiting subsidy design to ensure that it supports systems that offer both heating and cooling in certain circumstances.
While cooling may not yet be a widespread need in Scotland, it would be sensible to begin considering how and when cooling should be factored into future policy and funding frameworks – ensuring that Scotland is prepared for emerging climate realities rather than responding reactively.
To help households make informed and energy efficient choices, future programmes, regulations and advice services should anticipate the potential need for cooling. This must include support for passive cooling measures, to ensure that any shift toward cooling does not result in unnecessary energy use, emissions, or costs.
Policies to support decarbonisation in flats
Flats face specific challenges to retrofit, including co-ordinating groups of owners, the technical complexity of the retrofit required and varying incomes and ability to pay within groups of owners.
Given more than 36% of people in Scotland live in flats decarbonising these homes has an important role to play in meeting climate change targets. Last year, we published a report considering how to accelerate retrofit of flats in across the UK, learning lessons from countries across Europe.
The report set out a range of recommendations tailored to each UK nation. For Scotland one recommendation was to address the gap in financial support for groups of owners in flats, noting that current schemes do not include provisions for collective applications. We highlighted to need to enable groups of owners to access financial support and ensure that funding mechanisms are designed to support shared retrofit projects.
Further recommendations can be found in the report and we would be happy to provide further information or discuss this work in more detail with you if that would be helpful.
