SNIPEF, the Scottish and Northern Ireland Plumbing Employers' Federation, has voiced concerns regarding the timing of Scotland's heat pump rollout following a warning from the Climate Change Committee.

The trade association is urging the Scottish Government to avoid relying on a late-stage surge in installations, arguing that a steady increase throughout the current decade is essential for success.

Fiona Hodgson, Chief Executive of SNIPEF, noted that delaying the transition until the mid-to-late 2030s would place an unsustainable burden on the industry. She highlighted that the sector requires consistent growth to establish accredited competence, secure supply chains, and provide businesses with the necessary confidence to invest in new technologies.

The federation pointed out that high-quality heat pump installation depends on deep technical training and practical experience. SNIPEF warns that attempting to accelerate volumes too quickly without ongoing investment in apprenticeships and hands-on training could negatively impact installation standards and public trust.

Furthermore, the organisation called for support schemes to better reflect the urgency of real-world scenarios, such as emergency boiler replacements. Hodgson suggested that slow or unpredictable approval processes often force households back toward fossil fuel alternatives.

Fiona Hodgson, SNIPEF Chief Executive, said: "It is right that the Climate Change Committee has highlighted the risks of backloading delivery into the late 2030s. Delaying scale up until the mid-2030s would place significant strain on skills readiness, supply chains and installation quality.

"Scotland cannot rely on a last minute acceleration. Heat decarbonisation requires steady growth across this decade to build accredited competence, strengthen supply chains and give businesses the confidence to invest.

"Our evidence from installers shows that the constraint lies in the depth of training and practical experience required for high quality heat pump installation. Expanding volumes without sustained investment in apprenticeships and hands on training would risk undermining quality and consumer confidence.

"Support schemes must operate at the speed of real world purchasing decisions. In boiler breakdown scenarios, households need rapid approvals and payment certainty. If systems are slow or unpredictable, consumers will revert to fossil fuel replacements.

"Heat in Buildings legislation must be aligned with a credible long term workforce strategy, proportionate standards and procurement models that enable capable local SMEs to participate directly in delivery."
