They were both 230v, I've complained to the company and they want me to send it back at my expense to be inspected, I've asked them if they can send another for tomorrow and I'll send the other back, they said, " no"!! . So I've bought another one from someone else and am going to ask for a refund, I hope they don't give me any nonsense or I'll go down the route of "my house could have burnt down "

Did you fully change the pump or just the head. You didn’t leave the old rotor in and just change the windings part ?
FWIW, I never been able to claim a warranty on a pump replacement in a system and I've been in the game 25 years.
The only pumps I've ever managed warranty on are new boilers on new systems.
Pump warranties on existing systems - no chance

OK, this is a new development, it's still short cycling, however the period of time between it switching off and on again ids shorter so water is actually hotter because by the time it starts getting cold it starts warming up again. However ive just replaced a sink in the bathroom and when I turned off the water and drained taps the last of the water in the cold tap was warm, I read this may be something to do with thermostat in boiler being constantly in on position, could this have been the problem all along?

This sounds like a faulty venturi causing the pressure to the pressure switch to fluctuate. On some models this is a hard high temperature plastic and goes very brittle with age. Worth a check as they're quite cheap.
