My front room is served by just a small double radiator. In my garage
I have a Single Radiator which is twice as long as my existing double
rad.
Would I benefit by putting the long single rad in its place?

Measure the rads and look up the outputs on one the radiator
maufacture sites.
Such as:

But I suspect the outputs will not be much different.

Presumably you are feeling the cold.

Before increasing heat output look at keeping the heat inside. How
draughty is the room? Are the walls/loft/floor insulated?

Yes we are cold! The trouble is that the front door opens straight
into the living room. I have made the door as draft free as possible
but I think the problem is that the rad is right by the door. Is this
the best place for it?

Depends on the circumstances. Often it is.

Put a thermal door curtain on a Portiere rod.

A lot depends on the construction of the radiators. Does either have fins,
because this makes a large difference to the heat output?

If they are of same construction as each other (both un-finned or single one
finned and double one double-finned) the single will probably have
*slightly* more output than the double, but not all that much.

As others have said, look first at improving the insulation. Then calculate
the heat losses to see what size of radiator you *need* rather than just
using something you happen to have. Then make sure that the pipework is of
sufficient capacity to support the new radiator, and that the boiler can
support the whole house heating load.

You may be better spreading the heating around the room, especially
having some near where you sit.

I like having plenty of surpus heating capacity in a sitting room,
heats up quickly when you come in or the frontdoor gets opened and its
surprising how you notice the cold when sitting still.
