NHS TRT vs Private TRT in the UK: What You Get, What It Costs, and What to Expect

If your blood tests confirm genuinely low testosterone and you're experiencing significant symptoms, you face a choice that's not well-explained anywhere in the UK men's health space: go through the NHS or go private.

Both are legitimate. Both have significant trade-offs. Here's the honest breakdown.

The NHS Pathway

Getting diagnosed: Your GP can order a morning testosterone test. If it comes back below 12 nmol/L on two separate occasions with documented symptoms, they should refer you to endocrinology.

The reality: Many GPs are reluctant to investigate testosterone in men under 50. Many will run total testosterone only (missing SHBG and free testosterone) and tell men with total testosterone of 12–15 nmol/L with significant symptoms that they're "normal." This is a genuine gap in NHS practice.

If you get a referral: Endocrinology waiting times in most NHS trusts are 6–18 months. Some areas have shorter waits; many don't.

What the NHS prescribes: The most commonly prescribed testosterone treatments in NHS endocrinology are:

• Testosterone gel (Testogel, Tostran) - most common first-line
• Testosterone undecanoate injection (Nebido) - long-acting, injected every 10–14 weeks in clinic

What the NHS doesn't do well: Many NHS endocrinologists don't monitor oestradiol on TRT. They don't always measure free testosterone. Nebido's 10–14 week interval produces significant peaks and troughs in testosterone that many men find difficult. The inflexibility of the NHS protocol is the most common complaint from men who've gone through this route.

Cost: NHS prescription charge (£9.90 per item) or free if exempt. The treatment itself is cost-free beyond the prescription charge.

The Private Pathway

Getting diagnosed: Private men's health clinics - both in-person and online - will typically run a full panel including total and free testosterone, SHBG, LH, FSH, oestradiol, prolactin, thyroid, and metabolic markers as part of their initial assessment. The wait time from first contact to diagnosis is typically days to weeks rather than months.

What private clinics prescribe: More flexible protocols, including:

• Short-acting testosterone injections (enanthate or cypionate) on weekly or fortnightly protocols - produces more stable testosterone levels than Nebido
• Testosterone cream (applied to scrotal skin) - higher bioavailability per dose, preferred by some men for raising free testosterone
• Testosterone gel with more granular dose titration than NHS protocols
• hCG alongside testosterone to maintain testicular function and fertility
• Oestradiol monitoring and management (anastrozole if needed)

Cost: Initial consultation typically £150–300. Ongoing monthly cost: £50–200+ depending on clinic, treatment type, and monitoring frequency. Medication cost on top (which can be managed through services like Pharmacy2U for dispensing convenience).

The Hybrid Approach

The most cost-effective approach for many men is to get diagnosed and treatment initiated privately (where the full assessment and protocol flexibility are available), and then transfer care back to their NHS GP for ongoing monitoring and prescription once stable.

Most NHS GPs will continue a private prescription for established TRT if the prescribing and monitoring are appropriate. They can also order monitoring bloods through the NHS, significantly reducing ongoing costs.

This requires a cooperative GP - not all are supportive of private TRT. But the majority are reasonable if the prescribing is clearly from a reputable registered prescriber with appropriate clinical documentation.

What Actually Matters: Quality of Monitoring

The most common reason men on NHS TRT are dissatisfied is inadequate monitoring. Treatment without monitoring is the most significant clinical risk in TRT.

Whether you go NHS or private, the minimum monitoring you need is:

• Testosterone (morning, trough timing before injection or gel application)
• Oestradiol
• Haematocrit and haemoglobin (rising haematocrit is the most significant safety concern on TRT)
• PSA (annual)
• Full blood count

A private clinic that monitors all of these is safer and more effective than either an NHS protocol that doesn't, or a "TRT clinic" focused on maximising sales rather than optimising patient outcomes.

Do your research on any private clinic: check prescriber GMC registration, check what their monitoring protocol actually includes, check whether they employ qualified endocrinologists or GPs in their clinical team.
