Today I received his response:
Dear Mr Balch
Thanks for the email.
I have written to the Secretary of State for Business, Innovation and Skills taking up your concerns.
I will also liaise with other MPs concerned about this,
Rt Hon Andrew Smith MP
Now it may be that the Rt Hon Andrew Smith MP actually has tried to learn about the issues I raised, and has formed an opinion about them. You certainly can't tell from that letter though.
Hopefully I'm just being cynical and he actually is pursuing the issue...
