Heat pumps

Introduction

As heat pumps and other low carbon technologies will cause a rise in the demand for electricity on our network, we are committed to investing the right amount in the right places to continue to provide you a secure electricity supply. We are also committed to provide you with expertise and guidance to empower individual customers, businesses, local communities and the public sector to embrace a low carbon future.

If you're considering installing a heat pump, make sure you use a Microgeneration Certification Scheme (MCS) installer and get a properly accredited professional to complete the work. MCS certifies products and installation companies to help ensure they are installed to a high standard.

You will also need to provide an MCS certificate number to apply for the Renewable Heat Incentive, to confirm that your heating system has been installed in line with the MCS installation standards. You can find a list of certified installers and products on the MCS website.

Need to install a heat pump? Here’s what you should do: 

Contact an accredited heat pump installer to confirm whether your electricity supply is adequate to support the heat pump.

• Contact an accredited heat pump installer to confirm whether your electricity supply is adequate to support the heat pump.
• Provided there is no problem with your electricity supply, your installer should refer to this process flow chart to determine whether you need to 'apply to connect' by completing this form and emailing to domesticlct@enwl.co.uk., or 'connect and notify' by completing this form and emailing it to domesticlct@enwl.co.uk.

For 'apply to connect'

• We will carry out an assessment and confirm if there are any network restrictions.
• We will either send an approval to connect or a quote to upgrade the network. For most domestic customers, there will be no charge for your connection, but for larger heat pumps we may need to upgrade your supply which could incur a cost.
• Once you have installed your heat pump, your installer should notify Electricity North West.

For ‘connect and notify’

• Provided there are no issues identified; we will record your installation on our records.

For 'Upgrade to three phase'

If you currently have a single phase supply rated between 60 & 100A and now require more than 100A after your maximum demand/diversity calculations, you will need to send your ENA form to connectionapplications@enwl.co.uk. This is a chargeable service and the average cost of upgrading to three phase power, rated at 80A per phase is £5370.00.

 

Still not sure which email address to send your completed form to? 

Use the below questions to help identify whether you need to Connect and Notify or Apply to Connect:

• Is the heat pump under a single controller? 
• Will the total electrical energy utilised within the property, including the heat pump, exceed 13.8kW / 60 amps per phase? Applicable only to properties with Whole Current (WC) metering.
• Is the total heat pump Alternating Current (AC) input greater than 32 amps / 7.36kW?
• Is the heat pump listed on the Energy Networks Association online register?
• Is the heat pump classed as ‘Connect and Notify’?
