When installing a heat pump you are required to get permission from the District Network Operator - DNO - before making the connection. This is because the DNO, who are responsible for managing the network, need to check whether the local network can handle the additional load from a new heat pump installation. If you install a heat pump without permission, you could be forced to remove it.
DNO applications for existing electricity supplies are handled by us, in-house, as part of our service. When considering which heat pump partner to choose, this is an important factor to consider. Navigating the DNO process can be a challenge, and it is a requirement of the MCS scheme to have the DNO permission in place for a heat pump installation.
