Its business revolves around the integration of clean heat solutions, including heat pumps, solar photovoltaic (PV) systems, electrical batteries, and thermal storage with time of use tariffs. By treating these components as an integrated energy system, Boxergy helps its customers achieve significant energy savings and benefit the environment.

Dunster Biomass Heating

Dunster Biomass Heating designs, supplies, installs, and maintains large domestic and small commercial biomass heating systems, as well as small-scale district heat networks. It can also install air source heat pumps.

Evolve Plumbing

Evolve Plumbing is a dynamic company that specialises in traditional heating systems, primarily using gas. It also plans to expand into the clean heat and renewable energy market.

During this transition, the company aims to align its products and services with the Scottish Government's Heat in Buildings Strategy, which focuses on reducing carbon emissions by adopting cleaner heating solutions.

Exergy3

Exergy3 is a spin-out from the University of Edinburgh. It specialises in the decarbonisation of heat for industrial and domestic use.

Its flagship product is an ultra-high temperature thermal energy storage system. It was designed to store green electricity as thermal energy at temperatures of up to 1300°C. The stored energy is then discharged as hot gas to power thermal processes ranging from 50 to 1000°C.

The technology is modular, scalable, and adaptable, making it an ideal solution for industrial processes and large-scale heating systems.

Hydro-Genie

Hydro-Genie is a green technology company that delivers energy and emissions reduction solutions. Its revolutionary, patented technology dramatically increases the efficiency of hot water heating systems, cutting energy use and CO2 emissions by up to 50%.

Hydro-Genie works with boilers fuelled by gas, oil, liquefied petroleum gas (LPG), biomass, and electricity, as well as heat pumps. These can be installed or retrofitted in domestic, commercial, and public buildings.

Power Circle Projects

Power Circle Projects is a social enterprise with energy consultancy and energy services company (ESCo) offerings. The ESCo services focus on operating energy assets, including clean heat and heat storage technologies. This can involve multiple technologies and new clean heat technologies.

The company’s mission is to help local energy users access low carbon energy at scale in a way that's affordable, fair, and breaks down social barriers.

Prioto

Prioto helps businesses reduce their carbon footprint in a sustainable way by continually optimising their energy consumption and environmental conditions.

Through machine learning and automated control, the company helps older commercial properties reduce their energy use. It also analyses data to identify clean heat options that will provide ongoing efficiency or savings.

Q-zeta

Q-zeta Ltd is a spin-out of Quoceant Ltd, a successful renewable energy engineering consultancy. The company is dedicated to developing and commercialising a novel domestic heating solution.

The Q-zeta system is a unique combination of a low-cost, high-capacity thermal store and a small, efficient heat pump. The system offers both the heating efficiency of a heat pump and the value of off-grid energy storage.

Because the thermal store can be charged by running the heat pump during off-peak heating hours, you can use a much smaller heat pump to heat a given property size. This helps reduce cost and offers the game-changing potential to heat all homes within the current capacity of the distribution grid.

RI Cruden

Based in the Scottish Highlands, RI Cruden is a leading provider of renewable energy systems. It specialises in the installation and maintenance of clean heat technologies, such as ground and air source heat pumps, mechanical ventilation with heat recovery (MVHR) systems, solar photovoltaic (PV) panels, and battery storage solutions.

Founded in 2005, the company has grown significantly, transitioning from a focus on oil boiler installations to becoming a key player in the renewable energy sector. Its commitment to quality and sustainability has made it the contractor of choice for both residential and commercial projects across Scotland.

Sunamp

Sunamp is a world-leading manufacturer of phase change material (PCM) thermal storage technologies. Its mission is to excel in heat decarbonisation and make an impact in tackling climate change and safeguarding the planet for future generations.

The company designs and manufactures space-saving thermal energy storage solutions that make homes and buildings more energy-efficient and sustainable – all while reducing carbon emissions and optimising renewables.

The Energy Training Academy

The Energy Training Academy specialises in providing education and training focused on clean energy solutions, with a strong emphasis on clean heat technologies.

Its mission is to empower individuals and organisations with the knowledge and skills necessary to transition to a sustainable and low-carbon future.

The Renewable Technology Collective

The Renewable Technology Collective is an MCS-certified air source heat pump installer. It focuses on designing systems that deliver at least 400% efficiency. The company has serviced, maintained, or installed more than 500 heat pump systems across Scotland

The company works on existing air and ground source heat pump systems, as well as those using photovoltaics, battery storage, solar thermal, and mechanical ventilation and heat recovery. For homeowners who already have clean heat systems, it ensures their installations start or continue to operate efficiently.

It also uses the latest advancements in technology to optimise these systems, reduce running costs, and improve system efficiency. These interventions help improve systems of all ages by addressing issues in both hydronics and controls.

ThermaFY

ThermaFY transforms the way homes and businesses approach heating efficiency through advanced thermal imaging technology. It provides actionable insights that help reduce energy consumption, lower heating costs, and support the transition to net zero carbon emissions. 

By partnering with major corporations such as British Gas and Barclays and engaging with grassroots community groups, ThermaFY is uniquely positioned to drive substantial improvements in heating efficiency across the UK.

XKYEnergy

XKYEnergy is a leading renewable energy provider that specialises in the installation, maintenance, and servicing of heat pumps and solar panels. Committed to sustainable practices, it prioritises renewable energy solutions that reduce carbon emissions and promote environmentally friendly alternatives.

Eighty percent of the company's operations is dedicated to heat pumps and solar panels. The remaining 20% involves gas-related services, specifically the installation of gas boilers that are compatible with heat pumps.
