TRT UK 2026: Private Testosterone Replacement Cost, Safety & How to Access

The UK private TRT market has tripled since 2022. Some of that reflects genuinely under-diagnosed hypogonadism, but a lot of it reflects marketing to men with normal testosterone and treatable lifestyle drivers. This guide separates the two and covers what safe, guideline-based private TRT actually looks like in 2026.

Who actually needs TRT

The British Society for Sexual Medicine (BSSM) 2022 guidance, still the UK standard, requires all of the following:

1. Symptoms: reduced libido, erectile dysfunction, fatigue, low mood, loss of morning erections, reduced muscle mass
2. Two morning (before 11am) total testosterone results, taken fasted, at least 4 weeks apart
3. Total testosterone <12 nmol/L, or free testosterone <0.225 nmol/L if total is 8 to 12
4. Exclusion of reversible causes, obesity, poor sleep, opioids, cannabis, alcohol excess, untreated depression

If your total testosterone is above 12 nmol/L, TRT is very unlikely to help and carries real risks. A good private clinic will tell you that.

What safe TRT looks like

• Baseline: total & free testosterone (x2), SHBG, LH, FSH, prolactin, oestradiol, PSA, haematocrit, HbA1c, lipids
• Titration: check testosterone, haematocrit and oestradiol at 6 and 12 weeks
• Ongoing: 6-monthly bloods, annual PSA (over 40), annual DEXA at diagnosis for BMD
• Delivery: transdermal gel (Testogel, Tostran) first-line; injectable Sustanon or Nebido second-line

Pellets and compounded creams are not recommended in the UK.

Fair 2026 pricing

Component	Fair range
Initial consultation + baseline bloods	£180, £320
Titration bloods (weeks 6 & 12)	£70, £130 each
6-monthly review bloods	£90, £150
Gel (Testogel 50mg/day)	£30, £45/month
Sustanon 250mg (fortnightly)	£15, £25/month
Ongoing consultant reviews (6-monthly)	£120, £220

Total year-one cost: typically £1,100, £1,900 all-in. Clinics quoting a flat "£99/month" often skip haematocrit monitoring, which is the single most important safety marker.

The real risks

• Erythrocytosis (thick blood), requires haematocrit monitoring; occasionally needs venesection
• Fertility suppression. TRT switches off sperm production within 3 to 6 months; use hCG or enclomiphene alongside if fertility matters
• Prostate. TRT doesn't cause prostate cancer, but it can accelerate an existing one; PSA monitoring is essential over 40
• Cardiovascular, the TRAVERSE trial (2023) settled the debate: no increased MACE risk in properly monitored men. Unmonitored TRT is a different story.

Getting your GP on side

Shared care remains rare for TRT. Most NHS ICBs will not pick up prescribing unless the diagnosis was confirmed by an NHS endocrinologist. Realistic private options:

1. Full private care: consultation, bloods and prescription all through the private clinic
2. Private diagnosis + private prescription, self-collected at a UK pharmacy
3. NHS referral pathway: ask your GP to refer to endocrinology if morning testosterone is genuinely low

Red flags

• Prescribing without two morning testosterone readings
• No haematocrit or oestradiol on the monitoring panel
• Selling "boost" injections or compounded creams
• No named GMC-registered prescriber
• Willingness to treat total testosterone above 12 nmol/L

FAQs

Can I get TRT for "low-normal" testosterone? Rarely appropriate. Fix sleep, weight, alcohol and training first, most men gain 3 to 5 nmol/L within 6 months.

Will it affect fertility? Yes, plan around it or use hCG alongside.

How long do I stay on it? Usually life-long once started, because the HPG axis rarely fully recovers.
