TSH lab ranges are rather useless but used by doctors to define disease states. You need to be concerned with optimal.
Your thyroid status from the labs is inconclusive. TSH should be near 1.0
T3, T4, fT3, fT4 better near mid-range or a bit higher.
Please eval overall thyroid status via oral body temperatures - see below.
fT3 is the only active hormone and should be tested. There is no receptor for T4 and I suspect that few doctors are aware of that.
Many in UK are iodine deficient and the fact that only a few shops carry iodized salt is a big factor. In UK, if you do not consume dairy products you are not getting iodine that.
TT is not bad, FT is low. Low FT limits FT–>E2.
When you get T levels up, E2 will increase, but often higher than optimal E2=~80pmol/L and then guys should use anastrozole as needed get there. But a very few need higher levels to feel right.
SHBG is quite high, leading to more non-bioavailable SHBG+T that while lowering FT inflates TT that then overstates your T status.
You should test liver markers AST/ALT
SHBG is made in the liver to scavenge sex hormones and liver problems can increase SHBG some times.
FT changes a lot when measured directly, calculated FT has more confidence.
Cholesterol is good for now, TRT may reduce total cholesterol.
LH/FSH and low FT suggest that your testes are not working properly and that is untreatable unless a surgically correctable vascular abnormality is found.
FSH is very high and LH not so. In this situation you should be screened for testicular caners that typically secrete FSH. Alternatively, start TRT and LH/FSH should -->zero and then a lab later on that does not show FSH–>zero is a problem. The situation is vague because FSH levels are quite steady and LH is pulsatile with a short half-life. So the labs suggest that you need to know more but perhaps there is nothing wrong. Testicular cancer is a young man’s disease and not rare.

Evaluate your overall thyroid function by checking oral body temperatures as per the thyroid basics sticky. Thyroid hormone fT3 is what gets the job done and it regulates mitochondrial activity, the source of ATP which is the universal currency of cellular energy. This is part of the body’s temperature control loop. This can get messed up if you are iodine deficient. In many countries, you need to be using iodized salt. Other countries add iodine to dairy or bread.

I can be a bit abrupt in my replies and recommendations. I have a lot of ground to cover as this forum has become much more active in the last two years. I can’t follow threads that go deep over time. You need to respond to all of my points and requests as soon as possible before you fall off of my radar. The worse problems are guys who ignore issues re Thyroid, body temperatures, history of iodized salt. Please do not piss people off saying that lab results are normal, we need lab numbers and ranges.
The value that you get out of this process and forum depends on your effort and performance. The bulk of your learning is reading/studying the suggested stickies.
