The British Gas SARs/Recordings will only prove what you already know. That you had the conversation with them and that they did not take over the second supply, so in essence yes the recordings will help. What (if anything) brtish gas do about the situation depends on your conversation with them, and posisbly consumer focus.

Poiwergen supplied the property prior to you moving in and would have done up until British Gas took supply (this will be 4 to 6 weeks after signing up with them). Hopefully there'll be a record of this with E.on, although my gut feeling tells me that IF it exsists it'll be damn near impossible to trace. This feeling is bourne from E.on only recognising your tenancy in 2009, so if a record exists its lying somewhere in your landlord's account which they're unlikely to check. ( I would ask them about this however).

In light of the tenancy arrangments its looking all the more likely that British Gas failed to completely act on your instruction and your Landlady took her time updating Powergen/E.on.

Finger's Crossed something else turns up.

Have been contacted by E.On today, they have asked me to prove the contact i had with BG. I have therefore today written to head of complaints at BG and await their reply

Dear British Gas,

I have recently received a bill from E.ON (formerly Powergen) for £1207 for gas
supplied to the above address from May 2005 to April 2007. To the best of my
knowledge I was being supplied by British Gas on Dual Fuel account, having spoken to
one of your representatives within a week of moving in to the property (11th May2005)
on I believe the morning of Saturday 14th May I implicitly instructed the lady to take
over both electricity and gas supply at the property.
What I have only recently found out is that British Gas only took over the electricity
supply and not the gas, which while I appreciate you offer both utilities I cannot imagine
why I would want to choose not to have gas supplied by a company with Gas in their
name. I can still remember the conversation very well because I was pleased with being
able to speak with a UK call centre and the extra discount offered for taking a dual fuel
account.
I have recently contacted yourselves and you indeed have no record of my gas account
for this period; however you do have a dual fuel account for the property I subsequently
ported my dual fuel account to.
I have contacted Consumer Direct who have opened a case (ref: ******) and passed
me your contact details. What I would therefore like to kindly request is that you assist
me in proving this conversation happened back in 2004 so that E.ON will drop their
claim for £1207 under the Back Billing Code.
I would like to add that at no point up to August 2009 was I made aware by either
British Gas or E.ON that my instructions had not been followed by either phone, letter
or other. As you can imagine this is causing me a lot of worry at the moment and would
like to get this resolved as quickly as I can.
Thank you very much in advance for your assistance in dealing with this matter,
Yours faithfully

- once they reply i will update the thread, many thanks all!

Please See E.ON's response (Thanks for all youi support)

My one bit of advice from all this would be to contact CONSUMER DIRECT on 0845 404 0506 as soon as posible and don't give up!

Great outcome, but I think the E.ON letter meant to say "in light of the fact that the gas account was not set up correctly at the time, this means that the Billing Code applies to your account."
