I personally don't agree with this, the couple are giong to use the flat just as much, if not more, than the tenant on their own, so why should the single person have to pay more?
The fact that the couple are only using 1 bedroom is besides the point really, they are still going to use the rest of the flat.
bedroom space is trivial compared to living room, kitchen and bathroom - thats where the thrid person has an impact, and is why they should share it all equally.
The single dude is getting to live and have his own bedroom in a swish 2 bedroom flat that otherwise he would not be able to afford.
I you are working 9-5 all the time, where is the vast majority of your time spent? That's right, in the bedroom.
If you then moved your gf in after 3 months would he expect his rent to go down?

Your mates cost of living should be the same whether there is 1 person in the other room or 2 or even a whole family. Why should anyone subsidise your standard of living just because they want to have someone living with them? What if the GF actually has another house but just stays there 6 days a week? Should your rent drop?
Penalising the couple for no reason other than wanting to live together?
