Most likely cause & what to check
Check your programmer or timer — make sure hot water is scheduled to be on right now, not just heating.
If you have a hot water cylinder in an airing cupboard: look for the dial on the side (cylinder thermostat). It should be set to 60°C. If it's turned right down, that's your problem.
These checks are as far as a non-tradesperson should go. Call a Gas Safe engineer and tell them: "My heating works fine but I have no hot water — could be a diverter valve or zone valve fault."
