No, it's a combi boiler. It's been doing this for a while, but like I said there was plenty of flow before as long I turned the bathroom tap on at the same time. It's become especially bad this week after I topped up the pressure in the boiler though.
Also the boiler's about a meter from the kitchen sink which you'd think would mean there'd be enough pressure!

Sounds as though you have an airlock.
Is your hot water from a cylinder rather than a combo boiler?
Have you had plumbing work done/pipes drained? How long has it been going on?
Sometimes you can clear the airlock by covering the end of the kitchen mixer tap and turning on the hot and cold - thus forces cold water at mains pressure back up the hot wTer pipes and eventually forces the air out into the cylinder.
If you have a combi and no cylinder I'm stumped.
