That depends on the load you place on it in the house. If you are not
running heating in the house from the supply the chances are it may have
plenty of spare capacity.

it (in the long run) make sense to have a gas or an oil supply put in?

Yes.

I'm assuming that a gas supply would have to go underground and up
through the garden (like the mains electricity supply) and therefore
be expensive but if we had an oil tank fitted at the foot of the
garden oil could be piped up using a 12mm pipe run above ground.

The gas supply can often be provisioned by the contractors by them
digging a couple of holes, and then having the pipe run be "dug" by a
mole type device that burrows from one hole to the next. Far less
disruptive that digging up a trench.
