do I need to factor in anything if I want to go for a slightly bigger double pane rad?
I don't know the answer to this (do you need to consider whether your boiler is powerful enough?) but when I installed ^ those radiators ^ I didn't know that heat source pumps need bigger rads.
So when we do downstairs I am wondering the same thing - aesthetically we'd prefer smaller ones but if gas central heating is ultimately going to be done away with I don't want to have to rip up all our nice original restored floorboards to put in bigger rads...

FWIW the floor might have to come up anyway to fit larger diameter piping if you were to install a heat pump (which you probably won't, or at least, not on its own - on the assumption that your gaff is too inefficient at retaining heat to make one viable).
And then at that point you might be 'fuck it, it's time for underfloor heating and no radiators at all'.

You're under estimating how big radiators will be required for heat pumps, manufacturers of boilers are putting too much money into hydrogen that'll be for sure next rather than heat pumps in old houses. The cost is going to be too prohibitive for most consumers for heat pumps and everything that goes along with it.

Sorry to hijack the topic of new rads, but what with the price of gas I'm thinking of increasing the rad size in the most commonly used room (lounge) to use the fuel more efficiently. Currently an old (imperial sized) single pane thing which feels like it doesn't do much to the room temp- do I need to factor in anything if I want to go for a slightly bigger double pane rad?
