City Plumbing joins HPIN heat pump network
15th December 2025
UK: Plumbing, heating and electrical products supplier City Plumbing has signed up to the Heat Pump Installer Network (HPIN) to make installing heat pumps easier and more accessible for engineers.
The partnership gives City Plumbing customers access to the HPIN network and HPIN’s new free-to-use MCS umbrella scheme HPIN Direct, which removes the need for installers to obtain and pay for their own MCS accreditation.
HPIN and HPIN Direct, owned by energy supplier EDF, will provide City Plumbing customers with free access to MCS-certified heat pump installations from start to finish – from training and support to compliance and pricing. City Plumbing operates from a dedicated network of 300+ branches nationwide.
“This partnership gives City Plumbing customers better access to one of the most well established and professionally operated MCS heat pump umbrella services – a great option for our customers to make their business stronger,” said City Plumbing’s ASHP head of business development Jez Climas.
Clayton Browne, HPIN and EDF Heat Pumps MD said that the partnership would give thousands of boiler installers access to the market with no need to join MCS or pay an umbrella scheme.
