Over charged KWh by British Gas

Okey1001

Hi 

I’m in a dispute with BG, over the last 10 months I’ve used 440m3 gas, so on my latest bill they are saying 440m3 equals 13,852kwh I can’t see how they are getting to this calculation. 

Is my maths correct ?

440m3 x 39.1 x 1.02264 / 3.6 = 4,887.0829 kWh 

Please help prove I’m not going mad

It looks like BG have assumed you've got an Imperial meter, measuring in (hundreds of) cubic feet.

100 cubic feet = 2.83 cubic metres.

What does your meter measure in? I'd it's a modern electronic or smart meter, it's almost certainly cubic metres but older mechanical meters could be either.

Look at your meter  - look for the letters m3 or ft3.

Note the serial number.

Take a photo

Look at your bill

Is the serial number the same -  does it say m3 or ft3

It’s 10 months old it’s a smart Meter measuring in m3

This is what BG are telling me

Whoever did that calc need a new calculator

No it's definitely not.

You've got the c11 and the 2.83 in the total.

Use any gas calc website e.g.

https://utilitiessavings.co.uk/gas-kwh-conversion-tool/

That results for 1 = 100 ft ^3

A classic candidate for records not being updated

Ring BG and give them the serial number

Not that one.

They think that their image shows an Imperial meter that records in THOUSANDS of cubic feet.

I’ve found the answer yippee just got to get it across to BG now. 

They still have my old meter serial number on my bill which measured in imperial this was removed 10 months ago when they fitted the smart meter which now measures in metric. They are still calculating my units used as imperial and not metric.

Im guessing its for a higher volume - like a business meter - of which their are examples of on other sites - for businesses - but yes a bad choice - if I'd scrolled that far down.

It was iirc the second calc site on a quick google on my phone - and it worked - the first one didnt iirc allow you to change calorific value from 40 to the ops 39.1 or the compensation factor.

But either more than accurate enough to spot the 2.83
