I really don't think these things are as simple as people make them out to be. For example, there are various ways to get your results. Residents in England can access their NHS app and get information from there, GP's can access results, you can receive them face to face, and yes, you can receive this news over the phone. They do prefer the face to face method, but my wife has received news over the phone as have many others on here. I'm not sure about the email thing, though. But if requested, it doesn't seem like they can refuse such a request.

Red flags that i picked up on. Getting a colonoscopy requires preparation. It's not something you can just turn up and get randomly. Your large bowel needs to be free from waste, hence, why people getting one need to do the prep the day before. But there are different types of camera procedures up the backside. Some look at the entire bowel, some just look at the first part of the bowel. A&E being what it is, scans etc outside of your normal xrays require a good reason. He'd have to have been having a decent prolonged bleed for that to have even been a thing. So that sounds a bit off

You're in a decent position as to find out whether it's the truth or not. He has given you a timeline of 2 weeks. So in 2 weeks, ask him to show you a hospital letter, the email or whatever. Everything from the hospital will have a header on it. Usually will also contain a PDF file containing a copy of the letter. He's not obligated to show you any of this, but actions will speak louder than words in the case. If he's coy once he says he has the results, then it doesn't take a genius to add 2+2 together. You can also ask to go to the hospital with him. but that on it's own means nothing. I hate people going to hospital with me, and rarely have anyone tag along. I get really irritated with others in a hospital setting due to nerves. I prefer to quietly stew in the corner.

Yes they are. I’ve known medics face disciplinary action for communicating with patients via email - it is several years since most hospitals met the 4 hour waiting time target and that’s only the waiting time to be seen by anyone, let alone prepped and shoehorned into a busy endoscopy department’s schedule. My own wait for that was six months.  
Even NHS to NHS emails are only permitted using secure emails - with end to end encryption. 
The NHS app is secure but he stated “by email” which should never happen. 

That may used to be the case, but the NHS does use encrypted emails. At least in Scotland they do. I work on the GP (practitioner services here in Scotland) side of the NHS, and we have received data from hospitals via email, and we have sent sensitive emails to customers who have requested things via email.

Even the NHS website should state this is the case. You as the patient have a huge say in how you receive any information.

In fact, straight from the NHS site: "Health and care providers use encrypted emails which means that no one can see or tamper with the data while it is being transferred across the network or internet. Your own emails to them may not be encrypted"

Emails can be made secure.

Edit: I used the term "customers" for some reason. That should have read "patients".
