A VERY rough workout is to double what you are paying now, assuming you are on the variable, price capped rate? If you are averaging £89pm now then you are likely to be averaging £180pm over the next year (assuming you don't reduce usage or that something miraculous happens and prices go down). However, the government will pay £400 of that, split over Oct, Nov, Dec, Jan, Feb, Mar.
Oct - Mar: £180. Government pays £67. You pay £113
Mar onwards: You pay £180.
If you wanted to understand it in more detail...
Firstly, work out your yearly usage for gas and elec. Sometimes energy companies do this for and it's available online - have a look.
If not, do your bills or online account allow you to see what your metre readings were this time last year? If you do it this way you may need to translate gas from a cubic metre reading to a kwh - yell if you think you do and we can help.
Then check your latest bill to see what you are paying for each gas and electricity for:
Then total it all up for a yearly cost at current prices:
- Electricity standing charge per day x 365
- Electricity cost per kwh x the total kwh you use in a year
- Gas standing charge per day x 365
- Gas cost per kwh x the total kwh you use in a year
That will give you the total cost you face at current prices. Divide by 12 to understand how that translates to a monthly direct debit.
You get a gold star if your previous bills/online account allows you to see how much energy you used in each month and you do the sums above for each month of the year, allowing you to see the cost of the energy you use per month.
Then you can work out the projected cost per month over the next year, based on the predicted rises:
Oct - Dec: 82% increase over current prices
Jan - Mar: another 19% increase over Oct/Nov/Dec's prices
Apr - Jun: another 4% over Jan/Feb/Mar's prices
Jul - Sep: a 14% drop over Apr/May/Jun's prices
(the further out predictions may yet change dramatically, up or down, so be wary of those)
