UK HVAC & Heat Pump Skills Shortage: Future Solutions Ahead

Greetings, Net Zero News Community,

As we continue to stride towards our ambitious Net Zero objectives, one pressing issue looms large: a significant skills shortage in the heating, ventilation, and air conditioning (HVAC) sector, particularly in heat pump installation. This deficiency poses a serious threat not only to our immediate goals but also to the wider energy landscape in the UK. Tony Gittings from Rinnai sheds light on this critical situation and the cascading effects it may have on major infrastructure projects and the overarching aim of achieving carbon neutrality.

The HVAC industry, especially in the realm of heat pump installation, is grappling with a formidable skills gap. While the media and government discussions often focus on the more visible challenges associated with achieving carbon neutrality, the equally vital issue of training the next generation of installers and contractors has been largely overlooked. This is particularly concerning given that the lack of training and experienced heat pump installers could hinder progress in two pivotal areas: domestic and commercial heat pump installations and large infrastructure projects necessary for our transition to a green economy.

To put things into perspective, the number of qualified heat pump engineers in the UK has seen a notable increase, rising from a mere 3,000 in 2022 to 7,800 in 2023. Furthermore, during the first nine months of 2024, an additional 7,000 individuals obtained recognised qualifications. However, despite this encouraging upward trend, the UK Heat Pump Association estimates that to meet our Net Zero objectives, we will require a total of 33,700 fully trained heat pump engineers, with at least 27,000 needed by 2028. This stark reality underscores the urgency of addressing the skills shortage.

Charlotte Lee, the Chief Executive of the Heat Pump Association, has highlighted a critical paradox: while more individuals are training to become heat pump installers, the actual demand from consumers remains insufficient to encourage these newly trained professionals to actively enter the workforce. In her own words, “Interest in the training is growing. However, there is a gap between the number of trained individuals and active heat pump installers working in the market, with around 39 per cent of those who complete a training course currently not going on to install heat pumps.” This sentiment reflects a broader issue within the industry, where many trained professionals are not being utilised effectively.

Several factors have contributed to the challenges surrounding the heat pump workforce. These include inadequate government support, the retirement of experienced engineers, and a general reluctance among senior heating engineers to undergo retraining. These obstacles create a barrier to attracting qualified talent to the heat pump market, ultimately complicating installation efforts and exacerbating the skills shortage.

Moreover, the implications of this skills shortage extend beyond heat pump installation. The potential suspension or cancellation of large infrastructure projects due to a lack of skilled labour is an even larger concern. Major electrical grid upgrade initiatives are facing delays as the pool of qualified workers shrinks. The UK is currently undertaking numerous projects aimed at modernising its electrical transmission grid to accommodate the transition away from fossil fuels.

The National Grid has announced its plans for the “Great Grid Upgrade,” an ambitious initiative designed to adapt the grid to a new reality in which renewable energy sources play a fundamental role. The current infrastructure was originally designed to transport energy generated from coal-fired plants, and as we shift towards electrification, significant upgrades are required. The estimated cost of this extensive upgrade is around £16 billion. It will facilitate grid connections to offshore wind farms and rural solar installations, ensuring that renewable power can be efficiently distributed across the UK.

In addition to the Great Grid Upgrade, several other electrical grid connection and upgrade projects are underway to enhance access to renewable energy sources, which will ultimately help lower costs for consumers. For instance, the Viking Link project, a collaboration between the UK and Denmark, involves constructing a 475-mile interconnection that will link Lincolnshire with southern Jutland. This remarkable undertaking required an investment of £1.7 billion and has the capacity to power 2.5 million households in the UK. The National Grid estimates that this connection will save UK customers £500 million in its first decade by streamlining energy trade and optimising seasonal demand and pricing between the two nations.

Furthermore, the UK and Netherlands governments have unveiled plans for the Lion Link, a submarine interconnection that will allow for the transfer and trade of clean offshore wind-generated electricity between the two countries. This project is expected to produce 1.8 GW of energy, sufficient to power an additional 2.5 million homes, with operations anticipated to commence around 2030.

Scottish Power is also set to invest £5.4 billion over the next decade to upgrade its transmission network, contributing 80-85 GW of clean renewable electricity to the British grid. This ambitious commitment reflects the UK Government’s dedication to decarbonising the electrical grid by 2030. However, for these monumental projects to come to fruition, a motivated and skilled workforce is essential.

A recent survey conducted by the Prospect trade union has revealed concerning insights into the current state of the UK electrical sector. The survey found that 82% of workers believe staffing levels are inadequate, while a staggering 69% report experiencing a palpable skills shortage. Sue Ferns, Senior Deputy General Secretary of Prospect, emphasised the urgency of addressing this issue: “Upgrading the UK’s electricity networks must be a national priority. However, the much-needed infrastructure rollout described in this report will not happen without a skilled workforce to plan, build, operate, and maintain it.”

To foster an environment conducive to the installation of domestic and commercial heat pumps, as well as to successfully complete significant infrastructure projects, it is imperative that we cultivate a well-trained and motivated workforce. Without a diverse selection of skilled workers, the UK will inevitably face immense challenges in meeting its Net Zero targets and transitioning away from fossil fuels. Training a new generation of electrical and heating engineers is not just beneficial; it is essential for driving growth in a carbon-reduced society.

At Rinnai, we are committed to staying abreast of developments in the UK and international energy sectors. We will continue to provide updates on any news that may impact energy solutions and appliances, ensuring that our customers are equipped with the knowledge necessary for informed decision-making.
