I would remove radiators and flush out.
Flush pipework a couple of times, refit radiators and refill - run heating and flush when hot.
Then refill adding system cleanser or sludge remover and run for a week or so.
Then you can drain and flush a few times, fit the new radiators (if you want) and add inhibitors.
Without the price of the radiators it will cost around about £30 for the chemicals and whatever in labour. Not a bad little DIY job, if you're still not sure -get a plumber but they'd probably rather power flush it.
No-one in the family with a bit DIY knowledge that'll help.
