Current system is gravity fed. We have 2 aqualisa quartz showers with controllers in the airing cupboard next to the hot water tank.
We have poor hot water pressure in the sink in the kitchen. Is there a simple way to boost the pressure to just this tap?
Most advice online seems to suggest installing a shower/whole home pump. My concern is this might be an issue for the aqualisa showers and may involve changing those controllers to high pressure ones which is circa £300 each.
Is there a way to fit a small pump under the kitchen sink that simply pushed more hot water into the tap? One kitchen guy I spoke to was talking about an inline pump or something?
Is it something as simple as your hot tap being designed for high pressure systems? I bought a new tap/sink combo and the hot water just trickled out. Changed the tap for a low pressure one and problem solved!
The simplest way I've seen seems to be fitting one of these inline. I've no experience of them personally but I'm considering one for when I re-jig the bathroom.
Simplest as has been mentioned is making sure the tap is suitable for low pressure.
Also worth checking the flow straitened in the spout too.
Failing that one of these will probably work

The first thing I would do is check there isn't a blockage in the tap. See if you can undo the pipe connector without flooding the place and see if you get a gush or a dribble. How far below the header tank is the kitchen tap? That should be the determining factor for the pressure. And then, as Connect2 says, check you have a low pressure compatible tap.
other thing to check is whether the tails have debris in them. unscrew then and take a quick look. mine had a filter on the tail to protect the tap and this has clogged up with little bits of grit. flushed it out, good pressure now.
are other hot taps ok?
Was going to suggest the same as bigjohn. Turn off the isolator, undo the Flexi to the tap, open the isolator carefully with the Flexi into a bucket. Should show if the problem is the tap or the system.
Tap is a low pressure one so that shouldn't be the issue. We also have a water softner so doubt the pipes are furred up. I'll check the tails for debris.
