Do I need to change my water cylinder?

[king of pipes]

A thermal store needs to be heated to 65° to 70°c 365 days of the year in summer to provide Hot water and for Heating and Hot water in the winter months this is not fuel efficient, gas and electric prices have now more than doubled and the system you have is wasting lots of energy , with summers getting hotter why would you want to have that heat emitting from the cylinder into your home it must be so uncomfortable ?
A modern unvented cylinder is the way you should be going , choose one to match the system you are having installed it may be better to talk this through with your installer. Kop

This is in the airing cupboard on the landing. It's always very hot in there.

It will be, the hot pipes should have been insulated by the installers.

Yes, I was planning on having a plumber do it, but if a new tank is needed, then I’ll be killing two birds.

Your tank looks relatively new so whether it needs to be replaced depends on how the losses and running costs of the existing system compare with the losses and running costs of whatever hypothetical replacement system you have in mind. This needs to be calculated not guessed. The fact that the losses are occurring inside the thermal envelope of your house is also relevant to the calculation.

Whatever you do, ensure you check the mains flow rate/pressure before going unvented.

Thanks. It’s pretty powerful. At least 3 bar, I would say. It feels as powerful as in my last house which was measured at around 4 bar when we had an unvented system put in.
Put it this way, the shower heads will fly off the holders if we turn them up full blast.
