My apologies for the long post but am at my wits end!
I am also a landlord and the property I rent out has prepayment meters with just British Gas.
I had the meter installed on the 8th May 2007 and as of the 22nd February 2008 it has consumed 1128 units. Would you or somebody be able to tell me roughly how much this should have cost in total please. My tenant, a single mother of 4 children on income support, has been paying between £24 to £39 a week and regularly runs out of gas. This seems very excessive to me so I contacted BG who informed me that all is correct with the meter and my tenant was using on average about £22.50 of gas a week which is the national average. She did not agree with this and I have seen for myself how much she has had to top up in a week and it's always over £24.
I wasn't happy with this so have been researching all I can on how to convert the digital reading and work out how much the meter has consumed in kwh and then work out the cost since the installation date and came across an excellent post on this website explaining how to do this. If my calculations are correct I work out my tenant should have been paying only £12 a week for the gas used but before taking it further with BG wondered if someone can confirm my calculations to be correct or at least close.
Using prices given to me by British Gas this is how I worked out consumption and cost for the last 10 months.
Based on meter reading of 1128
1128 units x 11.15kwh = 12577 kwh
2680 kwh p/a for prepay @ 7.5p = 201.00
Remaing 9897 kwh @ 2.86p = 283.05
Total = 484.05
Divided by 10 = monthly cost = 48.40
Divided by 4 = weekly cost = 12.10
I know these calculations are not 100% accurate but need to know if I'm fairly close. I'm wondering if BG instead of converting my tenants gas at 11.15 x the cubic metre (modern measurement) are actually converting it at 31 x the cubic foot (old measurement).
Any advice would be appreciated
