Cheapest tariffs by payment method: Typical domestic dual fuel customer (GB)

Chart

Source: Energylinx (Until May 2017) & Energyhelpline (June 2017 onwards).

Information correct as of: September 2019

This chart compares the cheapest available tariffs offered by the six large suppliers with the cheapest tariff available in the market by payment method (direct debit, standard credit and prepayment). Figures are based on a typical domestic dual fuel customer.

From February 2017 the prices shown in the chart are calculated using the latest Typical Domestic Consumption Values (TDCV) that entered into effect from 1st of October 2017 (see the methodology section for more details).

In practical terms, this means that the tariffs offered after February 2017 are likely to appear slightly lower than those before February 2017.

More information

At-a-glance summary

Direct debit customers have traditionally been offered the cheapest tariffs, followed by standard credit customers and those using prepayment meters.  

After the introduction of the prepayment safeguard tariff in April 2017, the overall cheapest tariffs have continued to be those for direct debit customers. However, the ranking between standard credit and prepayment cheapest tariffs has fluctuated over time. Looking at the whole market, since February 2018 the cheapest prepayment tariff has been less expensive than the cheapest standard credit tariff. Among the six largest suppliers, the cheapest standard credit tariff decreased by £26 to £1,053 from £1,079 and remains less expensive than the cheapest prepayment tariff at £1,216.

At the end of August 2019, the cheapest direct debit tariff in the market was £207 less expensive than the cheapest standard credit tariff and £206 less than the cheapest prepayment tariff. The cheapest direct debit tariff has historically been at least £100 less expensive than the cheapest standard credit tariff.

A prepayment price cap was introduced on 1 April 2017, limiting the amount that suppliers can charge their prepayment customers. The default tariff price cap also came into effect on 1 January 2019, limiting the amount that suppliers can charge customers on default tariffs.

Relevance and further information

This indicator helps us understand pricing by payment methods, as well as how much other suppliers are able to compete with the six large suppliers for each method.

Methodology

We calculate the bill values associated with the different tariff types using a ‘typical medium domestic consumer’. As of October 2017, typical domestic consumption values (TDCV) for a medium consumer are 12,000kWh/year for gas and 3,100kWh/year for electricity (profile class 1). The chart includes collective switching tariffs from Q1 2016.

All tariffs shown in the chart are for a dual fuel customer. Dual fuel refers to a situation where a customer takes gas and electricity from the same supplier.

Tariffs with limited availability depending on customer features (for example, tariffs which are only available to new customers, also known as ‘acquisition’ tariffs, or tariffs restricted to certain regions) are excluded from the calculation to make sure that all tariffs considered are generally available to all customers across GB.

Tariffs available with white label suppliers are included in the calculation of the cheapest tariff. White label suppliers are organisations without supply licences that partner with an active licensed supplier to offer gas and electricity using their own brand.
