Good time to replace radiators?

A powerflush done well is the way to go.

Keep the rads and fit a magnetic filter on return pipe. Then add a branded inhibitor

my thoughts on this from your answers is someone is trying to sell you something you do not need

Thanks mate.

Like I said above I plan to drain the CH in the summer. Unless the water looks terrible, I won't bother with a power flush.

Thanks to everyone who has replied as well, you've probably saved me a decent bit of cash

Done well, that's the way to go for sure. Unless the system is really bad.
