How to use Velocity points to fly to UK with minimal cash outlay?

I have 200,000 velocity points and would like to go to UK in May/June this year. Can you suggest best way to spend my points in order to fly business class, without having to pay too much cash?
Thank you so much.

Fly Singapore Air with Velocity points or transfer to Krisflyer to redeem directly. Avoid Etihad if you want to minimise cash component.
