Who is this for?

This guide is specifically for tradespeople. It covers what you need to do before and during installation. Please follow this guide to ensure we can assist you as quickly as possible.

Step 1 - House size

Complete a whole house size calculation.

Step 2 - Complete an Electricity Supply Enquiry (ESE) form

Complete the ESE form to ensure the home's electricity service and local network can accept the additional load. This important step protects you and your customer!

The ESE form is an editable PDF. You can complete it using a computer, or print it and fill it out by hand.

Step 4 - We confirm receipt of your application

Once we've received your completed ESE form, we will send you written confirmation and begin processing your application.

Step 5 - Plan your installation

Plan your installation. If you comply with our Approved Heating Guidelines, your customer can benefit from our Economy 20 Plus discounted heating tariff.

Step 6 - Changing tariff?

If your customer is changing tariff, you will also need to submit a Connection of Meter form quoting your ESE number from your confirmation letter. You'll need to run a new supply from the meter to the boiler to take advantage of our Economy20+ tariff, with isolation at the meter and the boiler.

Please send your completed form to our Metering Team by the following methods:
