Our rates

The price you pay for your energy is fixed at the start of your contract, and this will not change throughout the duration of your contract. So no matter what happens to your energy’s wholesale prices during the term of your contract, your business will be protected from the market’s volatility.

There are some elements of your invoice that are charged at a rate either regulated or set by the government and are subject to change. These include some distribution and transmission charges as well as taxes such as the Climate Change Levy and VAT.

Your prices are highlighted on your monthly invoices, and will also be shown on your contract or renewal letter. Alternatively you can log onto your account online, or contact our Customer Service team who will be happy to help.

After your fixed term contract ends

You’ll be charged for your energy at the standard variable rates from the date your current fixed term period ends until the date you switch to another supplier or agree a new contract with us.

You can contact Customer Service on 0843 227 2377 at any time to find information on the current variable rate.

Deemed rates

The UK legislation covering the supply of electricity or gas stipulates that when an individual takes over the responsibility of a property, they’re deemed to have entered into an agreement with the registered supplier of that property. This means that the electricity or gas supplier is required to provide electricity to the customer and that the customer is required to pay for that electricity or gas at the supplier’s published rates until a new contract has been negotiated.

Our current electricity deemed rates are:

  Standing charge (p/day) Unit rate (p/kWh) Availability (p/kVA/day)
01-04 Profile 70 24.00 N/A
05-08 Profile 250 22.50 N/A
Half-Hourly 600 22.50 5.25


You can find out your electricity meter profile class by looking at the Meter Point Administration Number (or Supply Number) on your electricity invoice. The first (two digit) number on the top line is your profile class.

A Profile Class (ranging from 1 to 8) is used where the meter is not capable of recording Half-Hourly Meter Readings. Profile Classes provide the electricity supplier with an expectation as to how much electricity will be used throughout the day.

Your Profile Class will give your electricity supplier an idea of your daily electricity usage pattern. This in turn is reflected in the Standing Charge and Unit Rate(s) that you will be charged. As a general rule, higher usage needs a higher profile.

Our current gas deemed rates are:

  Standing charge (p/day) Unit rate (p/kWh)
Band 1 95 6.2
Band 2 150 6.2
Band 3 200 6.2
Band 4+ 250 6.2


Gas bands help determine the appropriate level of pricing for each customer. Bands are determined by the Annual Quantity (AQ) – an estimated figure, derived from meter readings, of the gas usage of a site over a 12 months period.
