My programmer keeps clicking on and off really really quickly, however, I still have hot water and central heating. Does that sound like a faulty programmer or something different

Faulty three port valve?
If it's *just* a programmer, it's definitely faulty - that should only switch on and off 2 or 3 times a day. If it's a programmable thermostat, it may be configured wrongly. You can normally specify the minimum on and off times. Which is it?
my programmer clicks on and off at the set times twice per day. But once on, it clicks away rapidly
A make and model of programmer might help.
But best guess is that the programmer has a loose conection or is shagged.
Had exactly that problem with a 20-year old Potterton EP3000. Replaced the main smoothing cap and it's as good as new (old cap was way low, guess too much ripple was making it continually reset).
Do you wake up and go to sleep at odd random times? Are you hot when you'd expect to be cold, and cold when you'd expect to be hot?

So the OP has nothing wrong with the CH and has the menopause?:-)
