then don't tell em :P
i've had a flatmate here now for the last year an half, and i neglected to inform the council, as i would lose my 25% single tenants discount off the tax.. lol the deal is, he buys the food, pays half the tax and i pay the rest of the bills.
altho this last 6 months he's been staying 4 days here, 3 days at his g/f's lol so that avoids that issue ;)
altho i'm moving house in a couple/few months time, so things will change by then.
i hate the TV license more tho..
