Yes, the second engineer thinks it is a leak based on the fact that he couldn’t find anything wrong with the boiler. I specifically asked him to do an air pressure test when I booked him but when I pushed him today he said he didn’t have an air pressure gauge. I think all I found out for sure today, is that there isn’t anything escaping through that overflow pipe.
Cool. Sounds like you're not doing anything based off the original installers recommendations. Putting in sealant is normal after a desludging. You'll be dislodging some debris which has found a home in the joints. Internal leak sealer helps cover minor leaks.

Thank you for your help.
So I should have allowed him to put the leak sealant in. I was really sold on Mikeys idea of the air pressure test. I booked the guy to do that job and then he turns up without the equipment. I didn’t have any confidence in him at all. I really want to find out where this leak is as there may be water damage that needs attention. I was concerned that leak sealant might just be a temporary fix. I also booked him to do the power flush today but when he arrived he said he wouldn’t have time today and would have to do it another time. I won’t have him back so it looks like it will be guy number 3 doing it.

huh, he doesn't want to be invited back.
just to clarify powerflushing only cleans and has nothing to do with finding or fixing a leak - except for them leaving in £8 worth of internal leak sealer at the end. i don't expect a heating engineer to carry it in the van and it's pointless if you're about to powerflush the system anyway.

Can we have some pictorial evidence of the aforementioned bacon sarnies on the what's cooking thread please Lisa?

Do not put leak sealer in as you will only mask the problem,
Your obviously not having much joy.
Is the pressure still dropping or is it stable
Did you get the plumber from the boiler manufacturers list of installers if not why not
Who balanced the radiators for you - you really dont need a plumber to do the pressure testing you must know a friendly builder they will be able to carry it out without to much hassle

We're not poles apart here. If someone is beginning this from scratch they can phone up their boiler manufacturer and ask for the number of an official service agent. That individual would see the job through all the way to the end rather than what is happening here. I'm with you on the friendly builder. The powerflushing thing is not an immediate requirement.

I balanced the radiators myself. It was time consuming but not difficult. If you are suggesting a builder can perform this pressure test, then I guess I can also do that myself. I’ll find some YouTube videos now.
Guy number one, who installed the boiler, was Ideal approved. I wrongly thought any heating engineer would be able to fix this problem.

two things
nobody tests with compressed air listen to people on screwfix at your own peril i doubt if any of them are qualified
as a test just fill your boiler to 2bar then turn off the flow and return levers at the boiler leave all day if you can and see if the pressure gauge drops - dont forget to turn your heating controls to off then put a container under the discharge pipe outside go and turn the flow and return valves back on and fire up the heating
if the pressure drops check the container if its empty we can now rule out any boiler issues

Thanks again for your help. So, switch the heating off. Fill to 2 bar. Are the flow and return levers, the ones I used to fill to 2 bar ? Put a container under discharge pipe. Leave for as long as I can bear the heating off.

Thank you Tom.
Kids are away for the weekend, so I can switch the heating off.
Pumped it up to 2 bar and put is a container outside under the overflow pipe.
All this was done at 10am this morning.
I’ll report back at 10am tomorrow morning.
