Scottish Enterprise Awards 2026 / 8 Most Trusted Commercial HVAC & Mechanical Contractor 2026 & Business Growth Excellence Award 2026 Fast-growing mechanical contractor Heat Wise Innovations has emerged as a leading player across the UK’s commercial, industrial, healthcare, hospitality, education, and residential markets. The company has taken the industry by storm in just two years, earning a reputation for combining experienced site teams with strong project management, fabrication, commissioning, and controls capacity. We heard more from Co-Founder and Managing Director Robert Walker below, as Heat Wise Innovations earns applause in the Scottish Enterprise Awards 2026. Situated in Stirling, Heat Wise Innovations is a mechanical, HVAC, and renewables contractor catering to clients across Scotland, England, Wales, and Northern Ireland. The company provides a comprehensive mechanical service, including commercial heating and plumbing, complex plantroom installations and upgrades, air source heat pump systems, district heating, gas installations, ventilation, underfloor heating, BMS and controls, pipework fabrication and welding, testing, and commissioning. Heat Wise Innovations was established in 2023 by brothers Robert and Jack Walker. The pair had completed apprenticeships in heating and ventilation engineering and, after learning the trade, steadily worked their way through the industry until they decided to branch out and form their own company. Hailing from a background where nothing was simply handed out to them, the brothers built Heat Wise Innovations with only the skills and relationships they earned along the way. Robert and Jack established Heat Wise Innovations with decarbonisation in mind. They built up a team of professional engineers, selecting seasoned experts they had previously worked alongside in past roles to equip the business with a depth of experience from the start. “There is a lot of skilled trade experience in the area,” Robert told us, “and we have built our team through friendships formed over many years on site.” Heat Wise Innovations has grown rapidly since its inception, driven by a strong team capable of delivering full mechanical packages across care, healthcare, education, hospitality, commercial, and decarbonisation projects, successfully delivering within both new-build and challenging live environments. The company has also launched a renewables division for both domestic and commercial work, ensuring that its operations grow alongside the changing market. Through the years, Jack and Robert have continued to update the team’s knowledge of heat pumps, renewable energy, and modern control, while staying grounded in the practical side of installation. The pair have remained incredibly hands-on throughout this growth, staying closely involved in projects alongside their management team to ensure that decisions are made quickly, problems are dealt with practically, and clients have direct access to the people responsible for delivering the job. During this growth period, Heat Wise Innovations has invested significantly into its own workshop and in-house fabrication capabilities. Such investment has been instrumental in enabling Heat Wise Innovations to prefabricate pipework, headers, frames, and plantroom assemblies, providing the company with greater control over the quality of its products while supporting increasingly complex plantroom and low-carbon installations. Today, Heat Wise Innovations combines the flexibility and drive of a young, growing business with the technical capability to deliver complex mechanical projects normally associated with much larger contractors. Throughout its ambitious growth, the brothers have never lost sight of their goals. “We want to grow Heat Wise Innovations into a leading Scottish mechanical engineer,” Robert told us, “but we want that growth to be built on our workforce, quality of workmanship, strong client relationships, and a willingness to take ownership when challenges arise.” In just two years, Heat Wise Innovations has grown from a turnover of approximately £150,000 to more than £2 million, while also building a workforce of 25 engineers. For such a relatively young company, the increasing scale and complexity of the projects Heat Wise Innovations is now trusted to deliver is a testament to the exceptional quality of its workforce and the stellar reputation it has established across the industry. What makes such an achievement particularly meaningful is that the growth has been sustainable and built around people. Heat Wise Innovations has created skilled employment, invested in its teams and facilities, and developed the capability to deliver major mechanical, plantroom, and decarbonisation projects across Scotland. At the same time, Heat Wise Innovations has worked hard to retain the values that first began its journey. Heat Wise Innovations continues to operate with a family-business mentality, instilling a strong sense of pride and responsibility within its team. Rather than simply trying to build a successful company, Robert and Jack have created something that holds a lasting legacy that their families, employees, and supporters can be proud of. The pair have established Heat Wise Innovations as a company that clients can trust from their first site visit through to handover. This family ethos extends to the wider Heat Wise Innovations team. Whilst the company has grown, Robert and Jack have worked tirelessly to retain the close-knit, hands-on culture that defines Heat Wise Innovations’ DNA. The pair have watched their workforce grow, AIM-Sep26169
