This guide is specifically for tradespeople. It covers what you need to do before, during and after switching a customers heating from oil and gas to electric.

Please follow this guide to ensure we can assist you as quickly as possible.

Step 1 - Advising your customer

After establishing your customer's budget and requirements, you should advise them on the electric heating solutions available to them and choose a suitable tariff.

We have 0% or low-interest heating finance options we can offer your customers.

Step 2 - Property and heating review

Before providing a quote you should carry out a review of your customers property and their current heating system. We recommend carrying out the following:

  • Check and assess the condition of the existing heating system, radiators, controls and hot water cylinder etc.
  • Assess installation practicalities and suitability, i.e. boiler and cylinder location(s), wiring, controls etc.
  • Calculate and establish heating requirement, size boiler (kW loading) and radiators.
  • Advise the customer on the installation details, timescales, choice of tariff and any disruption issues etc.

Step 3 - 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 6 - Provide an installation quote

Once you've received confirmation that we've approved the new loading for connection, you can then provide your customer with a formal quotation.

Step 7 - Changing tariff or meter?

If the fuel switch installation involves a tariff and meter change, you'll need to complete a Connection Of Meter form and return it to us.
