Hi Loch,
UK lad here also so hope i can help you in some way.
Started TRT around a year ago (younger than you for medical reasons) but even then this wasnāt worked out easily and it took so many barriers to finally start getting back to my normal self.
The NHS will never help! i have been down this avenue and if Nebido is what you want than please have, They are also fuckers with the blood tests. but there are so many more effective compounds out there man that will change your life. I would recommend private, biggest investment in your life and will change the way you view the world and your goals once optimised. When i mean private i aināt talking Harley St unless your into that.
It is also hard during this Pandemic to visit clinics face to face, a Teleclinic may be in your favour. (Balance My Hormones UK.)
The main thing you need to do is have your bloods checked, to me this i where it gets messy. Because there are ābloodsā and there are ābloodsā.
NHS will give you the most basic set of bloods, but without a through set the right decisions cannot be made.
There could be many reasons for feeling unwell, even if the person has high or Low T levels, so the surrounding BioMarkers need to evaluated just as much. Vitamin Levels, Bone, Liver, Kidney function can play a large factor.

From a wellness perceptive i think Test E or any other ester at 1mg/Lb if IM should not have any issues. is a decent rule of thumb although everyone is different so you will need to adjust protocol once started.
They even do Transdermal Gels which you apply daily. not as effective but you can always move on to IM if you feel they are not beneficial once you start.
