No. But you might have to replace the short pipe going into the rad,
depending on the design of the TRV - but it comes with the TRV, so is
simple to see if it's different.
You need the correct tool for this - an allen key that fits inside the
pipe. Not expensive.

I found a 1/2" cold chisel with a hexagonal shaft to get the spanner
on was just perfect.

I tend to use one from my socket set.

The correct tool gives you the thingy for fitting the bleed screws too,
though. And they're a bit more difficult to find a bodge for. ;-)
