The comprehensive document has been put together by the Heat Pump Association (HPA) together with electrical certification bodies NAPIT and NICEIC.
In 2024, nearly 100,000 heat pumps were sold in the UK, up 63% from 2023, highlighting the rapid growth of heat pump integration in electrical installations.
The new guidance covers the RCD selection process, explains the different types of RCD on the market, and outlines the specific requirements and considerations to safely and robustly protect heat pump installations.
The user-friendly format covers a four-step process, followed by frequently asked questions to help installers understand the various considerations.
It is intended to be informative for those with an interest in the subject and instructive for those with electrical competence.
Guide aims to boost customer satisfaction
Charlotte Lee, Chief Executive at the Heat Pump Association, said: “The Heat Pump Association is dedicated to supporting installers and promoting high quality heat pump installations to improve the consumer experience.
“This new guidance adds to the HPA’s ongoing efforts to support the sector as it scales up to meet increasing demand. It aims to simplify the RCD selection process and provide clear answers to common questions.”
A representative from NAPIT said: “Providing technical guidance to Competent Persons on the installation of renewable technologies, to ensure they perform to their optimum levels and leave consumers satisfied, is an unceasing objective for NAPIT.
“Being involved in this guidance bolsters this commitment when it comes to heat pumps. As a nation, we are well aware of the targets set out in front of us, and although these may feel steep, we believe these to be achievable with the correct tradespeople doing efficient installs of these technologies.”
A representative from NICEIC said: “This guide will streamline the understanding and implementation of RCD protection requirements, empowering installers to deliver safe and reliable heat pump systems.”
