What are my current prices?
Your current prices will be stated on your contract or if you have received one, your latest invoice.
What is included in a price?
Your price will be a mixture of energy costs,
transportation costs and the other costs we incur
supplying you with energy. The costs involved
differ depending on the type of meter(s) you
have, transportation costs, geography, and
usage profile, among other factors.
What drives prices?
The energy markets in both gas and electricity
are complex and volatile. They are affected by
the factors that influence supply and demand,
for example, changes in related commodities
markets, weather, national events, disasters and
politics. The volatility is caused by the change in
the relationships between these factors on a
daily basis. Gas prices have been heavily
influenced by the factors involved in importing
Gas as the UK becomes a net importer.
Electricity prices tend to follow the gas market as
prices are heavily influenced by the cost of
generating power and the commodities used as
a basis for doing so.
Can my meter be read remotely?
Yes, Total Gas & Power can offer a remote meter
reading solution. This will involve the installation
of additional Automated Meter Reading (AMR)
equipment at site.
For further information on how your organisation
can benefit from remote meter reading. Please
contact Customer Services on 01737 275587
(gas) or 01737 275772 (electricity).
What should my VAT rate be?
5% VAT – You will be charged 5% VAT if your site
is a non-profit making organisation (charity,
hospital, etc).
5% VAT – You can also be charged 5% VAT if
your site (at account level) consumes below 1000
kWh (electricity) or 4397 kWh (gas) in any given
month. This is calculated automatically on your bill.
5% VAT – A valid exemption certificate must be
received by Total Gas & Power. To find out if you
qualify, please contact HM Customs & Excise.
17.5% VAT – This is the standard VAT rate that
will be applied to the account if you are not
exempt or at the lower rate.
How do I submit customer reads?
Please see our Customer Meter Reads section in Customer Services.
Please note, in order for us to use electricity meter readings we require the reads from all of the registers showing on the meter. Please telephone from the 24th of each month to the 9th of the following month to ensure your reads are used, as your next bill will be sent out on the 10th of every month. Estimated gas readings should be submitted between the 25th of each month to the 4th of the following month.
Who reads my meter on the day of transfer?
- Gas: If our meter reading agent is unable to obtain a meter reading, then the gas transporter will supply an estimated reading based on previous consumption at the site(s).
- Electricity: You can supply us with your own (customer meter) read or let us calculate your reading based on our own estimated reading.
What do I do if I don't agree with the estimate I have been billed to?
If you receive an estimated invoice with which you are unhappy, please call our Customer Services team on 01737 275587 (gas) or 01737 275772 (electricity). Send the reads in online, or by fax or email (as before.)
We will then cancel the relevant invoice and send you a revised invoice based on the reads you have supplied.
If your revised invoice has produced a credit then this will be used to offset your future gas or electricity invoices.
How do I read my Electricity Meter?
To read a single rate digital meter, simply write down the numbers shown from left to right. Make sure to write down any zeros, including any at the start of the reading. Ignore any red figures. To find out how many units you have used since your last reading, subtract the previous reading from the new one.

An example of a meter with two rates.
You may have 2 readings if you pay different tariffs, for example day and night (the cheaper rate for electricity being night). For some businesses there can be even more readings.
Any meter that has over 6 readings or a 'STOD' meter (seasonal time of day) should call customer services or email the reading rather than submitting it online.
The readings on all these meters are typically viewed by pressing a button moving through the reads cycle. Be sure to submit all the readings when you read this meter.
To find out the number of electricity units you have used, take away the previous top line reading (shown in your last bill) from the new top line reading. Then do the same for all the other lines.
Dial Meters can vary in appearance. Using the tips in this section, however, reading your meter becomes very easy. Note the dials next to each other go round in opposite directions. Ignore any that are red.

Always write down the number which the pointer has just passed – this is not necessarily the nearest number to the pointer. If the pointer is anywhere between, say, 4 and 5, write down 4. If the pointer is directly over the number, like on dial 2 above, write that number down and underline it: 5.
The meter reading example above will initially read 4 5 9 2 8. But this reading now needs adjusting to remove small variations in the pointer positions. Look at the numbers you have underlined. If one of these numbers in the sequence is followed by a 9, reduce the underlined figure by 1 (as the dial has not passed the number yet.)
So the amended and correct meter reading of the dials shown above is 4 4 9 2 8 units.
If you're still having difficulty reading your meter or are unsure about anything, please call our Customer Services team on 08456 013754. They will be delighted to help.

How do I read my Gas invoice?

To calculate the gas used, subtract the previous reading from the present reading for each meter.
- Multiply the figure by the Correction Factor (CF).
- To calculate the number of M3 used, multiply
this figure by the Conversion Factor (shown in
the table on the reverse of your invoice).
- Multiply this figure by the Calorific Value (CV).
- Divide this figure by 3.6 to convert to kWh’s.
- Multiply the number of kWh’s by the unit price
to calculate the cost per meter.
|
- Add together the cost of each meter to
calculate the total cost, excluding VAT.
- Apply Climate Change Levy (CCL) unless any reductions apply.
- VAT is added at 17.5% unless any exemptions
apply.
- The sum of these calculations amounts to the
Total Gas Sales.

Meter Serial Number |
| Meter Point Reference (MPR) |
A unique number that identifies a specific gas supply. |
| Correction Factor (CF) |
A fixed meter specific factor applied to take into account the effect of temperature and pressure on actual gas flow. |
| Calorific Value (CV) |
This represents the amount of heat or energy in a given volume of gas. An average calorific value is calculated monthly by the transporter and allows for any periodic or regional variations in the quality of natural gas. |
How do I read my Electricity invoice?

How to calculate your non-half-hourly invoice
- To calculate the number of Billed Units
(electricity consumed), deduct the previous
meter reading from the present one.
- Multiply the Billed Units by their respective
price.
- Non-half-hourly meters may have a number of
different readings. The time periods and prices
these refer to are stated in your contract.
These meter readings may be actual, customer
or estimated as indicated on your invoice.
- The total (consumption) is the consumption for
all readings for the period of use. The total cost
associated with the Total Consumption is also
stated.
- Multiply the Billed Units of Standing Charge by
the price (if applicable).
- Multiply the Billed Units of Capacity Charge by
price (if applicable).
- Add together Capacity Charge and Standing
charge to obtain the total of other charges.
- Apply Climate Change Levy (CCL) unless any reductions apply.
- VAT is applied at 17.5% unless exemptions
apply.
- The sum of these calculations amounts to the
Total Electricity Sales.
|
How to calculate your half-hourly invoice
- Billed units are calculated for the period of use
and are measured in kWh’s.
- These units are then multiplied by their
respective prices.
- Half-hourly meters may have up to six
consumption periods. The time periods and their
applicable prices are stated in your contract.
- The total (consumption) is the consumption for
all consumption periods for the period of use.
The total cost associated with the total
consumption is also stated.
- Multiply the Billed Units of Standing Charge by
Price (if applicable).
- Multiply the Billed Units of Capacity Charge by
Price (if applicable).
- Add together Capacity Charge and Standing
Charge to obtain the total of other charges (if
applicable). Please note that there may be
charges specific to your individual contract.
- Apply Climate Change Levy (CCL) unless any reductions apply.
- VAT is added at 17.5% unless any exemptions
apply.
- The sum of these calculations amounts to the
Total Electricity Sales.
