Lesson 8. Electricity. gas and water

Some people say ‘you don’t get ’owt for nowt in this life’. Most things have to be paid for and that includes the electricity, gas and water you use in your home.

The amount of electricity, gas (and water in some homes) used is recorded on a meter. The meter is read every 3 months and a bill is sent. An electricity bill could look like the one below:
Payment

Some people simply pay their bill when it arrives. Other people arrange to pay part of their bill each month. They are often given a small discount if they arrange to pay the bill each month.

 EXAMPLE:

Ally has received his electricity bill:
present reading = 61982 previous reading – 60732
cost of one unit of electricity = 7.6 p.

VAT is 5%.

How much does Ally have to pay?
units used = present – previous =

61982 – 60732 = 1250

cost of unit =

1250 × 7.6 p = 9500 p = £95.00
VAT is 5% of £95.00 =
5/100 × 95.00 = £4.75
Total bill = £99.75
