The Energy Saving Trust has released a report detailing some of the programmes they deliver on behalf of the Scottish Government.

The report is updated annually to reflect relevant programme developments over the course of each year and to provide up to date information on their impact. Data in this version of the report relates to the 2021/22 financial year.

Some key figures on heat pumps in Scotland:

• Home Energy Scotland 2021/22 evaluation

  • Since receiving advice from a HES adviser, 47% of customers had installed at least one energy efficiency, low carbon heat or renewable energy improvement and 38% of customers were planning to install at least one improvement in the next 12 months.

  • Of the measures installed, the top five that were attributed to HES advice in 2021/2 were air source heat pumps (86%), new boilers (65%), electric storage heater upgrades (58%), solar PV (56%) and loft insulation (51%).

  • Evaluation evidence shows that, where HES provides specialist in-home advice on more complex measures such as low and zero emission heating and other domestic renewables, energy storage systems and solid wall insulation, around 90% of customers who received this support and acted attributed that action, at least in part, to the support they received.

• Home Energy Scotland Grants and Loans

  • In 2021/22 HES Loans supported households to install 2,131 renewable measures. The number of heat pumps for which funding was committed through the HES Loan scheme increased by two thirds, from 762 systems in 2020/21 to 1,284 systems in 2021/22.

  • Funding for energy efficiency is up to 75% of the combined cost of improvements up to the maximum grant amount of £7,500 (£9,000 with rural uplift). Grant funding for heat pumps is up to £7,500 (£9,000 with rural uplift).

  • Evaluation of the renewables loans show that they are highly influential and cost-effective in encouraging the installation of renewables systems; 93% of funded actions were at least partly attributed to the loan and 54% would not have happened at all without the loan.
