Cutting Gas Bill but now damp smell

Try turning up the radiator a bit. The trouble is that cold air doesn't hold as much moisture as warm air. If the room is too cold, it is likely to be damp. Are the windows double glazed? if not try doing so with cling film. It will help to stop heat loss to the outside. I'm assuming you don't want to close the curtains 24/7. Opening a window will simply allow any heat in the room to find its way outside and probbly make the problem worse.

The best way is to tackle the damp at source. Ie cooker hood, extract fan in shower/bathroom.

since the main source is the people in the house that is obviously the way to go

Shoot your wife.

It will save on all your bills.

How big is "horrendous"? Energy here costs around £5,000/year split roughly 50:50 oil:electric (no mains gas)...

How far have you turned the radiator down? If you go much below 15 C room temp damp will start to be a problem. Shutting the door won't help either a bit of ventilation is required. Start with keeping the door a jar for a week and see if it helps. Wouldn't open the window.

Actually, if the room was well insulated there should not be too much extra cost in heating it.

Certainly will, AFAIK you don't pay ant rent to HMG when detained at Her Pleasure. B-)

I recently bought a dehumidifier to dry out some plaster. Aside from doing that job well, it did leave the room feeling noticeably more comfortable. A dry cold maybe ;-)

Even now the plaster's dry it seems able to collect a few litres a day.

I would put that down as pretty bad but I expect that's a mansion.

that is bad. think I am about £1000 leccy/£2000 oil and a couple of hundred wood.

Low radiator setting, door ajar, keep windows *closed*, leave curtains closed?

Get a dehumidifier!

Treats the symptom not the cause. Not to mention consumes electricity, say 2 units/day, 30p/day, £100/year. Cheaper to keep the door open...
