Shower problems

My shower is a mixer tap with shower attachment that runs from my combi boiler (worcester bosch). Last couple of days I noticed the hot tap to turn it on was stiffer and not turning as much, but then my son said when he had a shower the last couple of days it was down to a trickle and going hot and cold. I checked the boiler yesterday and pressure was very low so assumed that was it, but just tried the shower today and its still not right, hot tap stiffer than ever have to turn several times to even get a trickle and shower running cold. When I checked the boiler it wasn't doing anything. When we tried cold tap pressure seemed fine.
I am not sure what the issue is and not sure if I need a plumber or whether it is connected with my boiler.
Any suggestions appreciated so I don't get the wrong person to come and fix.
Thanks

My mixer tap looks like this, except have replaced the shower fiitting over the years, it was in the house when I moved in 19 years ago. https://www.toolstation.com/deva-tudor-taps/p56897

It's probably just the tap. Run a hot tap somewhere else; if that's fine then just assume it's the tap.1

As above, other taps OK?
Depending on what is inside the housing, you can replace the old for a newer ceramic cartridge or whatever it contains. My old tap fittings were washer but they take a standard ceramic cartridge and replaced them all for 1/4 turn.
But the unit will need to be taken apart to see what needs replacing. Just did my shower diverter valve and really needed to part out for comparison as the unit is no longer made, but the valves are.
Spanners and care is all I needed.1 -
If tap is stiff then it’s the tap.Take shower head off and descale and try again is another option
if the shower temp ok to start then goes cold then warm again. You need to run another tap say the kitchen if the same happens then boiler issue likely a heat exchanger1 -
As above if the bath shower mixer tap was previously working Ok and provided a safe and enjoyable shower experience. Then new tap inserts cartridges could be considered.
Thats the cheapest option

Plenty of repair operatives and items available off the shelf to if necessary repair that bsm, personally i would only fit a thermostatic mixer item.
But everyone knows why, Ta for the comment

The cold tap works fine, but that is probably because it is rarely used.Might seem easy for someone who knows what they are doing and has the correct tools I do have some spanners and other tools, but not sure if they would be the right ones. I have done a few minor plumbing jobs in the past. I have changed a ceramic cartridge in the sink taps that match the mixer, but it was years ago and I had spare taps under the bath that I could pinch the cartridges out of, they are now gone. I think these would be bigger than the other taps, but without removing wouldn't know.GDB2222 said:akh43 said:My mixer tap looks like this, except have replaced the shower fiitting over the years, it was in the house when I moved in 19 years ago. https://www.toolstation.com/deva-tudor-taps/p56897Just checked out a video on replacing the cartridge and now remember what I did, so think I could manage that, but not sure about anything else or changing the whole tap if that is actually needed as there is limited space around the bath area as right next to the sink. Not sure whether I should try myself or just bring a plumber in to do it.

bsm= bath shower mixer.
if yours is as the link that you showed earlier then (after shutting water supplies off) the body of the tap can be removed from the pillars without having to go under the bath.1
