Banging Rattling noise Boiler or pipes nearby?

[MancAnt]

Hi all as per the topic...... whenever I turn on just the hot water tap in the kitchen...let it call for heat and heat up the water then turn it off, as u turn off tap I get the noise form where the boiler is located (upstairs airing cupboard).
Happens half way through the video...any ideas??
