I've been told that when replacing a boiler it is is a good idea to power flush the system to remove rust and sludge...problem is it seems to be quite an expensive procedure with installers quoting £300-500 on the price of installation, with some saying it is a specialist procedure and don't do it. Would it be effective enough if I removed the rads and ran them through with my Power Wash as a cheaper option?...the system does need it as some of the rads are cold at the bottom end.

Yes, a lot pf people prefer to take them off and squirt them through with a hose. More labour intensive though, and mind you don't drip on the carpets.
You can the use a chemical cleaner when you re-assemble. There will be less stuff for it to work on.
You might consider a Magnaclean device, it traps any circulating black sludge that remains, and you can empty it out periodically. Costs in the region of £100.
Whatever you do, be sure to refill with corrosion inhibitor after cleaning to avoid it happening again.

You would not do any harm doing what you suggest although mains water might be better.
It would not clear everything from the rads or anything at all from the pipes.
Most firms fitting a new boiler include power flushing at about £150-£200 when fitting a new boiler as its part of the procedure ( for a professional firm ). Cowboys dont do it of course!
Make sure you tell the installer if any rads are cold at the bottom as that indicates quite a serious problem.

taking the rads off is the best way to get rid of the sludge. It is essential to flush a system. I do this on many boiler swaps. If the system is not too bad i just put x400 sludge remover in the system and come back a few weeks later and drain the system 2 or 3 times to flush it.
