Underfloor Heating Setting

We have one room in our house (a dining room extension to the kitchen) that is in regular use, it's the only room in the house with underfloor heating, with winter approaching we will soon be staring to use it again, what's an economical setting for it being mindful of the upcoming energy costs.

What type of UFH? If electric the most economical setting is to remove the fuse and lock it away.2

Is it temperature controlled from the boiler or seperately0

Well most people are turning down the temp on their boilers for winter. So would.advise the same and find out where your comfort levels are.1

Off and have TV dinners would be cheapest option. Turn it down as low as you are comfortable with is cheaper option.Barnsley, South Yorkshire

The main difference between underfloor and radiators is response time. Radiators will quickly warm the air whereas underfloor can take a while.
Often when we feel cold we over heat the room to try and warm it up (radiators are good for doing this) but it's more efficient to keep that cycle of hot/cold relatively flat from the perspective of how it feels. The simple rule of thumb is to have the underfloor on all the time with a 1-2 degree reduction when the room isn't going to be used for an extended period (eg night). Have it step up the temp 1 hour before you normally start using the room and switch off 1 hour before.
You can make it more efficient if you increase the temp reduction so it's colder in the room when you're not in it, the trick is to start heating it again at a the point where it will be up to temperature when you come to use it.... but that requires a bit of experimenting and isn't very flexible if you use the room early.
As for reducing boiler temp (one of the other responses). You need enough temperature differential for a condensing boiler to operate efficiently and the outgoing water needs to be about 65degrees and about 50 on the return, this is more efficient that running a boiler at 55 on the flow because it will never condense.
