What is a Distribution Network Operator?

There are 14 different Distribution Network Operators (DNO) across Great Britain. These are the licensed companies that own and operate the network of towers, transformers, cables, and meters that carry electricity from the national transmission system and distribute it across Britain.

The DNO acts as a gatekeeper to the national transmission grid, distributing energy from the grid to homes and businesses. 

It is required to satisfy itself that the local grid can cope with demand. So, for heat pump purposes it must ensure that it can manage the demand of the new pump being installed before granting permission for connection. 

This is because heat pumps are viewed as equipment that have the potential to disturb the quality of voltage provided to the DNO.

This document aims to provide Public Sector Decarbonisation Scheme (PSDS) Applicants with best practice information. Our guidance is designed to help you get your heat pump connected to your local electricity network.

Heat pumps are a key solution for decarbonising buildings and will be critical for meeting the UK’s commitment to achieve net zero by 2050.
