About us
At Infinite Heating & Energy, we help homeowners, businesses, developers and community organisations transition to smarter, more sustainable energy solutions.
Making renewable energy straightforward
Renewable technologies can seem complicated, particularly when several systems need to work together. Our role is to make the process easier to understand.
From the initial consultation and system design through to installation and aftercare, we provide clear advice and practical recommendations tailored to each property.
Whether you are considering a heat pump for your home, solar PV for a commercial building or a joined-up energy solution for a community facility, we will explain the options and guide you through each stage.
Our story
Infinite Heating & Energy was founded by Josh McNally following more than 15 years of experience as a plumber and heating engineer across Cambridge and the surrounding areas.
Working on residential and commercial projects gave Josh extensive experience in heating and mechanical services. He qualified in gas and oil systems while developing a detailed understanding of how thoughtful system design can improve comfort, efficiency and reliability.
As renewable technologies became more advanced and accessible, Josh recognised the benefits they could provide for homes, businesses and public buildings. He saw an opportunity to combine traditional heating expertise with modern renewable technology, supported by clear communication and dependable customer care.
Infinite Heating & Energy was established to help customers adopt these technologies with confidence. Today, we continue to design and deliver carefully considered systems that reduce energy use, improve comfort and support long-term sustainability goals.
Experience across different properties
Our work covers residential, commercial and community-sector projects.
We may be installing a heat pump in a family home, designing commercial solar PV, supporting a developer with low-carbon heating or helping a church, school or village hall work towards decarbonisation.
Every project receives the same careful consideration. We take time to understand the building, how it is used and what the customer wants to achieve before recommending an appropriate solution.
Commercial and community projects often require additional coordination, compliance and project management. We work closely with building owners, developers, facilities managers, consultants and other stakeholders to plan the work carefully and keep disruption to a minimum.
Josh McNally
Founder and Director
Josh leads Infinite Heating & Energy, overseeing business strategy, project delivery, technical standards and customer experience.
His background in traditional heating systems and renewable technologies continues to shape the company’s approach: understand the building, design the right system and support the customer throughout the process.
Josh is supported by a team working across system design, project coordination, engineering and installation.
A note from Josh:
“Having worked in the heating industry for more than 15 years, I’ve seen renewable technologies develop into practical solutions that can make a genuine difference to homes, businesses and communities.
“When I founded Infinite, I wanted to build a company that combined technical expertise with clear advice and dependable support. Our aim is not simply to install a system, but to help every customer feel confident in the decisions they make—from the first conversation through to long-term aftercare.”
