Is this not the done thing anymore? The last couple of times heating has come up in conversation people have been surprised that our heating goes off at 10pm, then back on at 6am - it's off in the day too. I sometimes work from home, so stick it on in the day if cold.
They told me it was expensive and inefficient, but I thought that most people didn't have it on 24hrs/day - maybe I'm wrong, what do you do?
