Home Decarbonisation Skills Training Competition

The Home Decarbonisation Skills Training Competition (HDSTC) is a scheme to provide grant awards to a range of training organisations in England. Appointed training providers will provide appropriate training and support to installers operating across the different Department for Energy Security and Net Zero retrofit schemes.

Supporting the supply chain in this way will help build capacity and resilience for home energy retrofit delivery more widely, as well as scaling up delivery further as Government works towards meeting its 2030 and 2050 decarbonisation targets.


Phase 2 (2023-2024)

£8.85m of grant funding has been made available through the competition to registered training providers based in England. The aim of the competition, which is being facilitated by the Midlands Net Zero Hub, is to award funding to a range of providers to deliver accredited training at scale to support the retrofit sector. It is expected that around 8,000 courses will be delivered through the second phase of the competition.

Through the second iteration of Home Decarbonisation Skills Training Competition, Further Education colleges, training academies, and manufacturer training centres can bid for up to £1m to deliver one or more of the following aims:

– Installation training to the specific technology standard – for example, National Occupational Standards, PAS 2030:2019 standards, PAS 2035 standards or higher.

– Training in the installation of one or more individual energy efficiency measures, including training for individuals with existing construction skills and training for those new to the sector

– Support for training in retrofit assessor and retrofit coordinator skills to PAS 2035 standard, leading to the relevant qualification
