Do you mean that when the hot water is on the heating is on as well or that you can't turn the hot water on unless you turn the heating on?

have a look at the programmer. its common on older systems not to have independent hot water and heating.
basically if the boiler is on the hw is on and a two port valve gives ch as an option alongside the always on hw.
this can be remedied by the addition of a new programmer/pipe configuration and upgrade to a fully pumped system.

could have a summer valve . follow the pipe from the pump one should go to the cylinder then tee for the htg there may be a manual gate valve on the radiator circuit old systems were like this

What is a summer valve?

 

[Millsy 82]

Is the system a Y or S plan? How long has this problem been going on? Could be a loose wire on programmer.

 

[Dannyparty92]

Open up the wiring centre and check the wire from the cylinder stat back to the wiring centre and as long as the water is cold in the hot water tank and your programmer is set for hot water to be on you should get 230 ish volts reading on a multimeter but please only do this if you are competent. Also your "cousin" seems to be having a lot of trouble with plumbing?

summer valve is just a gate valve on the htg to turn htg off as the system as no zone valves basic plumbing set up

without knowing the system design its hard to give any advise, more details are required.
