the immersion switch is off usually. we have been turning it on for about an hour a day amid the warm weather because that's the only way we could get hot water when the heating was off.
Scalding hot water and heating / hot water confusion

That must be why it's scalding hot, unless thermostat on boiler failed.
As for other problem, either mid position valve is on the wrong way or its wired incorrectly.
I recommend you call someone in who knows how to wire up y plan system correctly. Ie not the guy who watched you fit it last time.

The cylinder thermostat is new. I will check if valve is on right way round. If its on incorrectly will that make the hot water come on separately?
I have photos now of the valve and control panel wiring. How do I post them in here?

It's hard to see much from photos of wiring, usually.
You'll need a multimeter (and to know how to use it safely) so you can verify it yourself.

When you look at that, and what you have, it'll be clear as mud at first.

But it's a good help when you are trying to help via a net forum
Believe me it may help one of us spot something amiss

Having realised the three way valve was round the wrong way, and turned it round the right way, the whole thing is fine now. Thanks for all your help chaps
So one or more of these attempts fixed the problem were it not for the valve being installed the wrong way?
If there are two ways to install this valve and you had no other information you had a 50-50 chance of doing it correctly.
BTW, IMHO, the more clues furnished, including schematics, the better the odds of someone being able to help you.
If you assume any single clue is irrelevant it implies that you already know the solution to the problem.
