Heat pumps can increase the demand on your electricity supply. Before installation, your installer should assess whether your existing supply is suitable and advise if any upgrades are required.

When looking to install a heat pump we recommend following these steps:

Step 1: Contact an installer

Step 2: Check your electricity supply

Your installer should complete an Adequacy of Supply Assessment to confirm whether your existing electricity supply can support the proposed heat pump installation.

Step 3: Notify us or apply for an upgrade works

If your electricity supply is suitable, your installer can install the heat pump and notify SSEN of the installation within 28 days.

If the assessment identifies potential issues or that upgrades to your electricity supply may be required, an application should be submitted to SSEN for a Load Check to be completed before the installation can proceed.

Step 4: Install your heat pump

Once any required approval and upgrade works have been completed, your installer can proceed with the installation.

Information for installers
What we need to know about your heat pump installation:

•  The make and model number of the heat pump you're looking to install.
•  Details of any existing heat pumps at your address.
•  The maximum demand of the premises.
•  Whether the electricity supply is looped.
•  The electricity supply cut-out rating. If the cut-out rating or looped status is unknown or uncertain, it can be determined by applying for a Load Check here.
•  To help determine the rating and looped status, please send us a photograph of the cut-out and incoming supply with your application. Please do not open the cut-out unless authorised to do so. Further guidance on cut-out ratings is available on the ENA website.

Timelines:

Notifications

Where its determined that the existing electricity supply is suitable, the heat pump can be installed and SSEN need to be notified within 28 days of installation.

Load Checks

Where an assessment of the existing electricity supply is required, SSEN will typically respond within 10 working days of receiving a completed application.

Upgrades

If upgrades to the electricity supply are required, timescales will be provided as part of the assessment process.

Our Heat Strategy

The UK and Scottish Governments have set ambitious targets to rapidly increase heat pump and zero-emission heating system installations in the coming decade. SSEN is committed to ensuring this transition is managed in a fair manner for the households, businesses and communities it serves. As a Distribution Network Operator (DNO), SSEN’s responsibility is to ensure a safe, secure and reliable supply of electricity. In the transition to net zero this means investing in our network and investigating smart solutions to accommodate the extensive electrification required to meet the UK’s decarbonisation targets.
