If you're looking into TRT in the UK, one of the first big decisions you'll face is whether to go through the NHS or a private UK TRT clinic. Both routes have genuine pros and cons. This article breaks them down honestly — including the situations where we'd happily tell a patient that the NHS is the right starting point.
Can You Get TRT on the NHS?
Yes — TRT is available on the NHS, but the threshold is strict. Typically you need to demonstrate:
- Total testosterone repeatedly below the reference range (usually < 8 nmol/L)
- Clear symptoms consistent with hypogonadism
- Two morning blood tests on separate days
- Often, a referral to endocrinology before prescribing
If you sit in the "borderline" zone — say 8–12 nmol/L with obvious symptoms — the NHS usually won't prescribe, even though your symptoms are real and treatable. This is where most UK men end up exploring private TRT.
NHS TRT: What You Actually Get
- Cost: free or £9.90 per prescription
- Bloods: usually total testosterone, sometimes LH/FSH and SHBG
- Medication: most commonly Sustanon 250 every 10–14 weeks
- Monitoring: variable, often 6–12 monthly
- Access: GP + endocrinology referral, often months of wait
For men who fit the criteria neatly, NHS TRT works. The downsides tend to come from the infrequent injection schedule (which can cause peak-and-trough symptoms) and limited monitoring.
Private TRT in the UK: What You Actually Get
- Cost: £100–£200/month once stable (see our UK cost guide)
- Bloods: comprehensive panel including free T, E2, SHBG, PSA, FBC, lipids, thyroid
- Medication: choice of short-ester injections, gels, creams; hCG if fertility matters
- Monitoring: every 3–6 months, included in most packages
- Access: appointments within days, online or in person
Private UK TRT clinics also tend to spend far more time with you — 30–60 minutes per consult versus the 10-minute GP slot — and will tailor your protocol rather than fitting you to a template.
Side-by-Side: NHS vs Private TRT UK
| Factor | NHS | Private UK TRT |
|---|---|---|
| Cost | £0–£9.90/script | £100–£200/month all-in |
| Waiting time | 3–12+ months | Days to weeks |
| Eligibility | Strict — under ~8 nmol/L | Symptoms-led + full bloods |
| Blood panel | Basic | Comprehensive |
| Delivery options | Usually Sustanon 10–14wk | Injections, gels, creams, hCG |
| Consult time | ~10 min GP slots | 30–60 min with a TRT specialist |
Which Should You Choose?
NHS may be right if…
- Your total testosterone is clearly below 8 nmol/L on two morning tests
- You have a supportive GP who is comfortable managing TRT
- You're happy with standard Sustanon injections every 10–14 weeks
- Cost is the main consideration
Private UK TRT may be right if…
- You have clear symptoms but your numbers are "borderline"
- Your GP has dismissed your concerns or won't refer
- You want stable levels, not peak-and-trough Sustanon
- You need flexible delivery (work travel, needle-averse, etc.)
- You want to preserve fertility with hCG
- You can't afford to wait 6–12 months to start feeling better
Can You Combine the Two?
Yes — many UK patients start privately to get moving quickly and comprehensively, then later ask their GP about a "shared care" arrangement to shift prescribing onto the NHS. Shared care depends heavily on your local ICB and individual GP willingness, but it can be a good long-term cost saving.
The Bottom Line
NHS TRT is excellent for the men who qualify, but its narrow threshold leaves a large group of symptomatic UK men without help. A GMC-registered UK TRT clinic like TRT South fills that gap — faster, more comprehensive, and more personalised — for a cost most UK men find well worth it once they feel the difference.
