My energy

It’s important to keep on top of your energy so we’ve made our statements as easy to understand as possible.
But if you do need anything explained please give us a call or read the Citizen’s Advice guide.
If you pay by Direct Debit, we’ll produce a statement at the end of each month detailing your energy charges. You don’t need to do anything it’s just for information.

Your energy charges are made up of two components:

1. Unit Rate (a charge based on number of kWh of gas/electricity you’ve used), and
2. Standing charge (based on number of days we’ve supplied energy to your property)

We calculate your energy charges by multiplying the amount of units you’ve used (or estimated to have used) by the tariff unit rate you are on (£/kWh). We then add the daily standing charge multiplied by the length of the charging period and apply VAT (charged at 5%).

For example, if you’ve used 750 kWh of gas and 180 kWh of electricity over a month (30 days):
Gas unit rate 3.00p/kWh 3.00p x 750 = £22.50
Standing charge 21.00p/day 21.00p x 30 = £6.30
Electricity unit rate 15.00p/kWh 15.00p x 180 =£27.00
Standing charge 21.00p/day 21.00p x 30 = £6.30
Total (Ex. VAT) £62.10
Add VAT (charged at 5%) £62.10 x 5% = £3.11
Total (Inc. VAT) £65.21

You should always check whether the unit rate and standing charge are including or excluding VAT.

We ask for monthly meter readings so we can bill you on your actual usage. However, if we don’t receive a meter reading by the end of your billing period, we need to produce an estimated value to generate a statement.

Electricity
We estimate usage by using your Estimated Annual Consumption (EAC). This is a number held and managed within a centralised industry database which estimates what the yearly usage that a particular meter will be. You’ll find this figure on any energy bill or statement.
Each electricity meter point in the UK has a corresponding EAC associated to it. A typical EAC for an ‘average’ home is 3,100 kWh each year. We adjust your EAC for seasonality as you would usually use more electricity during the winter months than the summer.

Gas
We estimate gas usage in a similar way to electricity, however the figure we use is called your Annual Quantity (AQ). Each gas meter point in the UK has a corresponding AQ associated to it. A typical AQ for an ‘average’ home is 12,500 kWh each year.

EAC and AQ numbers are reviewed and can be updated from time to time so you may see a different figure on your energy statements.
If you don’t feel these estimated values reflect your usage, please submit meter readings so we can use your actual usage.
If you submit a meter reading after you statement period, it will be included in your next energy statement.

A standing charge is a fixed daily cost that is used to cover the fixed costs of providing your home with both gas and electricity.
These costs include keeping your home connected to the energy network, carrying out meter readings and maintenance related charges.
Your standing charge also goes towards the cost of government initiatives and reducing carbon emissions for the cost to deliver electricity and gas to your home.
Please note, you may have a separate standing charge for each meter.

A fixed energy tariff guarantees your unit-price and standing-charge prices will stay the same for a defined period. You still pay for amount of energy you use so your monthly bill will change to reflect your this.
When you sign up to a fixed rate, you get peace of mind that the basic prices won’t go up.

A variable energy tariff means that the price per unit of energy is not fixed and could move either up or down. So, you could benefit from a drop in prices but should also plan for any potential rises as a result of fluctuating wholesale energy or other industry costs.
It’s worth noting that if you’re on a variable tariff and your energy supplier makes any change that could be to your detriment, they need to give you at least 30 days advance notice of this change.

A Tariff Comparison Rate (TCR) is a number (introduced by Ofgem – the energy market regulator) that we’re required to show to help people to compare tariffs from different suppliers (comparing apples to apples).
It is not a ‘tariff rate’ and not something you can switch to.
TCR is calculated by using the same unit and tariff rates on the tariff on offer but the usage estimate is based on what Ofgem has defined as medium usage (12,500 kWh for gas and 3,100kWh for electricity) not your individual situation.

The calculation is total annual cost for a ‘medium user’ divided by number of units’ energy used, for example:

Gas TCR
365 (Days in a year) x 21.00p (standing charge p/day) = £76.65
12,500 x 2.70 (unit rate p/kWh) = £337.50
Total annual gas cost = £414.15

TCR = £414.15 (total annual cost) / 12,500 (annual consumption) = 3.31p/kWh.

Electricity TCR
365 (Days in a year) x 21.00p (standing charge p/day) = £76.65
3,100 x 10.50 (unit rate p/kWh) = £325.50
Total annual electricity cost = £402.15

TCR = £402.15 (total annual cost) / 3,100 (annual consumption) = 12.97p/kWh.

Your Personal Projection is your forecast energy cost for the next 12 months. It assumes you don’t change or renew your energy tariff over this period, you use the same amount of energy as you did last year taking into account any meter readings you have given us and includes any discounts or charges that may apply (like VAT).

If you are on a tariff that is due to end in the next 12 months, we’re required to assume that you will move onto our UP Variable tariff (our Variable tariff) when your current tariff expires. For example, if your current tariff expires in 3 months, your calculation will be based on 3 months on your existing tariff + 9 months (the remaining time) on our UP Variable tariff.

Your Personal Projection is only an estimate and doesn’t include any credit or debit balance you may have on your account.
