Any sort of electrical heating (short of a heatpump*) is going to have similar costs.
If it's at all possible to install an extra radiator it's going to be the only sensible option if you care about long term costs.
(* There are a few models of portable air conditioner that can work as a heatpump for heating. No idea how rubbish they are.)

£1 does seem reasonable at first (so I started looking at tube heaters for my garage) but then realised it would add 50% to our electricity bill!
