A pilot scheme designed to boost the number of qualified heat pump installers has released its first findings.
The programme offers newly trained heating engineers a free air source heat pump to install in their own homes, providing practical experience in a controlled environment.
Early results suggest this hands-on approach may improve installers’ confidence and technical skills, potentially smoothing the path to wider heat pump adoption across the UK.
Pilot project tests hands-on training approach
The ‘Start at Home’ pilot began in November 2023, involving 40 heating professionals new to heat pump installation.
Half of the participants were given the opportunity to install an air source heat pump in their own homes, gaining practical experience in a controlled, low-risk setting. The other half formed a comparison group, continuing with standard training and industry entry.
The aim was to determine if this “learning by doing” approach could accelerate installers’ confidence, technical skills, and credibility when entering the heat pump market – a sector considered critical to meeting the UK’s net-zero ambitions.

Nesta’s newly released report indicates participants who swapped a gas boiler for an air source heat pump reported improved confidence and deeper technical understanding in system design, heat loss calculation and commissioning.

Living with the heat pump allowed them to gain ongoing insights into performance and user experience, knowledge they could share with future customers.
Around half of those who installed a pump at home are now exploring routes to full Microgeneration Certification Scheme (MCS) accreditation, proving the experience may also help meet professional standards required in the retrofit market.
Scaling up and next steps
Following positive initial results, Nesta is working to expand the ‘Start at Home’ approach nationally.
The organisation is engaging with manufacturers, trade bodies, certification schemes, and local authorities to support the launch of independently run ‘Start at Home’ programmes.
Nesta plans to continue evaluating the impact of these programs to refine best practices.
