For future maintenance, you could add drain cocks at each ground floor

to drain radiators individually in a mess free way for decorating.
I used Pegler Terrier valves for this and can recommend them.
Andy,
I presume you mean this sort of thing?

Is the price of £10.18 + VAT *each* or for a box of 10?
That's each, but a list price of course. I think I paid about £6 or
so at Travis Perkins with a bit of arm twisting (although it was part
of an order for about £300 or so.
This looks good, but appears to move the connected pipe further away from
the rad - so some pipework changes would be needed in the case of a
retro-fit.
It does slightly. I have microbore pipework which runs from outlet
plates (like electrical ones) on the wall. It wasn't a problem to
bend the pipe slightly. With 15mm, it might take a bit of replumbing
depending on the pipe layout.
Screwfix do one with the drain at the end, which appears to maintain the
pipe position

Do you know whether this does the same job? [It's not clear from the picture
whether the drain connects to the tail, or only to the external pipe].
It does one of the jobs, which is to provide a drain for the system as
a whole, or the ground floor radiators to be more precise.
However, the drain may be on the pipe side of the valve and if so
won't allow individual radiator drain down which the Pegler one will.
Of course that function can be done by undoing the unions but can be
messy and harder to control.
It's hard to say though. Even though the drain cock is opposite the
tail, it could still be radiator side if the valve seat is in the
bottom near the compression fitting.
