What is the Tariff Comparison Rate (TCR)?
You can use your TCR (Tariff Comparison Rate) as a guide to help you compare your tariff with others, from us or other suppliers. It’s based on how you pay, your standing charge and unit rate. It includes your discounts and VAT at 5%. It’s a guide only as it is based on Ofgem average use figures: electricity 3,100 kWh/year and gas 12,500 kWh/year. Your actual charges will depend on the energy you use. To find out about your tariff and how we work out TCRs, go to our help and support pages.
