Dynamic Price Tariffs for electricity
From June 2026 a new Dynamic Price Tariff for electricity will be available to customers that allows prices to vary every half-hour based on wholesale market rates.
Electricity prices change every half-hour reflecting wholesale market prices, with standing charges still applied. Prices are lower during low demand or high renewable generation and higher during peak demand times.
How the standard dynamic price tariff works
This tariff includes a fixed standing charge and electricity prices that change every half hour. Prices go up and down during the day but are capped, so customers are protected from very high prices.
Suppliers publish the next day’s 48 half‑hour prices in advance through apps or online accounts, allowing customers to plan when to use electricity at cheaper times. Prices are usually lowest overnight and highest in the early evening, though this can change daily depending on demand and weather.

Customers can reduce their electricity bills by using electricity at cheaper times of the day.
Customers can save by charging their electric vehicle, running a heat pump or immersion, and using appliances like dishwashers and washing machines during lower‑priced half‑hour periods that fit their daily routine.
Customers can make this easier by using timers, smart plugs or a home energy management system, so appliances run automatically when electricity prices are lowest, helping them save money with little effort. Where possible, customers should avoid using energy-intensive appliances during peak‑price periods, as these are usually the most expensive.
Business customers can also reduce costs by using electricity at cheaper times, with options depending on how each business operates.
Customers are advised to contact their supplier to check if they offer a dynamic price tariff and for more information and guidance.
The tariff is best suited to customers with smart meters who have flexible usage. Before switching, customers should review their usage, speak with their supplier and compare options.
