This fake financial spam is not from British Gas / Centrica but is instead a simple forgery with a malicious attachment.

In the only sample I have seen before, there is an attached file named archive-0910001923884.docm which has a VirusTotal detection rate of 3/52. Analysis of this document is pending, but it is likely to drop either the Dridex banking trojan or Locky ransomware.

UPDATE 1

The Hybrid Analysis of the document plus the VirusTotal scan of the dropped EXE look like Dridex. The download location for that document was:

skropotov.ru/system/logs/87h754.exe

C2 to block:

UPDATE 2 

The comments on this VT report indicate other download locations:
