The higher upfront cost compared to gas boilers is a challenge for increasing rollout of heat pumps and effective financing options are required to enable this.

This report identifies how innovative business models, such as subscriptions including payment plans, financing and ‘heat as a service’ models, could support the rollout of heat pumps by helping with the upfront investment, which is often a challenge for consumers.

Through a literature review and analysis, and in-depth discussion with stakeholder groups, it explores how three business models could be implemented in Scotland via pilot schemes.

Summary of findings

  • A limited number of heat pump finance offerings are currently available to customers in Scotland. Other than an upfront purchase, most of these are finance only payment plans for the purchase of the heat pump only. Uptake for these plans is very low. Funding from the Scottish Government currently includes an up to £7,500 interest-free loan and a grant to the equivalent value. There are heat pump on subscription offerings across Europe, but these are also fairly limited, reflecting an immature market.
  • The following range of business models could be applied to heat pumps in Scotland: a) finance only, b) financing lease, c) subscription, d) heat as a service.
  • Adding the installation of energy efficiency measures, an energy tariff suitable for heat pumps and energy advice to these propositions could increase their appeal.
  • There are non-financial barriers such as complexity of installation, consumer difficulties in understanding fuel bill savings and a current lack of consumer demand.
  • Specific barriers to heat pump subscription models include lack of understanding and reassurance around consumer protection and contractual issues – for example, when moving properties.
  • Stakeholders have a mixed appetite for piloting new approaches, with the main challenge being provision of finance. Other challenges and risks include ensuring heat pump performance and supply chain capacity.
