Yes, you can get TRT on the NHS. Testosterone deficiency is a recognised medical condition, the NHS treats it, and if you qualify the treatment is free at the point of use apart from the standard prescription charge. The route runs through your GP, usually with a referral to an endocrinologist, and it depends on two morning blood tests showing that your testosterone is genuinely low.
That's the short answer. The longer one is that plenty of men with real symptoms don't get treated on the NHS, and it helps to understand why before you start, so you can make the strongest case or decide early that another route suits you better.
Who qualifies for TRT on the NHS?
The NHS describes late-onset hypogonadism (testosterone deficiency that develops in adult life) as an uncommon, specific medical condition rather than a normal part of ageing, and notes it's more likely in men who are obese or have type 2 diabetes. In practice, qualifying comes down to two things: symptoms that fit, and blood results that confirm deficiency.
UK practice follows the British Society for Sexual Medicine (BSSM) guidelines. The 2023 guideline says total testosterone should be measured between 7am and 11am, on at least two occasions, preferably four weeks apart, ideally fasting and not during an acute illness. On those two samples:
- Below 8 nmol/L is testosterone deficiency. Where symptoms are present, treatment is usually appropriate, and this is the group the NHS treats most readily.
- 8 to 12 nmol/L is the grey zone. BSSM says free testosterone should be checked here, and that a total testosterone below 12 nmol/L on two separate morning samples usually warrants treatment where symptoms fit. This is where NHS and private practice most often part ways.
- Above 12 nmol/L, BSSM says testosterone therapy isn't usually required. In our own practice there's some discretion between 12 and 15 nmol/L where symptoms are significant and free testosterone supports it, but you're unlikely to be treated on the NHS at these levels.
- In men with pre-diabetes, BSSM supports treating a total testosterone below 14 nmol/L to reduce progression to type 2 diabetes.
Two details matter more than they look. First, timing: testosterone peaks in the early morning, and an afternoon sample can read several nmol/L lower than a morning one from the same man. Under the guidelines, an afternoon result usually has to be repeated in the morning before it counts, which can add weeks. Second, free testosterone: most of the testosterone in your blood is bound to SHBG and unavailable, so a man with high SHBG can have a normal-looking total and a free testosterone that's frankly deficient. If nobody measures SHBG, he's told he's normal. There's a fuller explanation of the thresholds in our TRT UK guide, and you can run your own numbers through our free testosterone calculator.
How to get TRT on the NHS: the route step by step
The NHS pathway is straightforward on paper. The friction is in the detail, so I've added what to ask for at each stage.
1. See your GP and ask for a morning test
Low testosterone isn't part of routine screening, so you'll usually need to ask for it specifically. Book a morning blood draw before 11am, ideally before 10am, fasting if you can manage it. Ask for the panel to include SHBG, LH, FSH and prolactin, not total testosterone alone. Take a written list of your symptoms with you. Our low testosterone symptoms page is a reasonable checklist, and reduced morning erections, low libido and loss of body hair are the symptoms most specifically linked to deficiency.
2. Repeat the test
One low result isn't enough. Diagnosis needs two separate morning samples on different days, and a GP following BSSM guidance will repeat the test, adding LH and FSH to work out whether the problem is in the testes (primary hypogonadism) or in the signal from the brain (secondary). If your total testosterone is very low, below 5.2 nmol/L, with low LH and FSH or a raised prolactin, BSSM recommends referral to endocrinology or a pituitary scan to rule out a pituitary cause.
3. Referral to endocrinology
The NHS's own guidance says that if your results suggest deficiency, your GP may refer you to an endocrinologist, a specialist in hormone problems, and that if the specialist confirms the diagnosis, testosterone replacement may be offered. In practice most GPs won't start treatment themselves without that specialist input. This is where the time goes: in much of England, endocrinology waiting lists currently run from several months to over a year. The wait varies a lot by area, so ask your GP what it is locally before you commit to it.
4. Treatment and review
If the endocrinologist agrees you need treatment, they'll prescribe, and ongoing prescribing and monitoring are arranged between the specialist and your GP. Once you're stable, reviews on the NHS are typically annual. BSSM recommends assessing men at 3, 6 and 12 months after starting, then yearly.
Where NHS TRT applications usually stall
The system is set up for clear-cut cases, and most men who come to us aren't clear-cut. The consistent sticking points are:
- Wide reference ranges. Laboratory ranges are often quoted as roughly 8 to 30 nmol/L and aren't age-adjusted. A result of 9 nmol/L is flagged as within range. For a symptomatic 34 year old, it isn't remotely normal for him.
- SHBG and free testosterone not measured. So the grey-zone decision BSSM describes never actually gets made.
- Oestradiol not measured at all. Oestrogen matters in men, and more so once treatment starts. Without a baseline there's nothing to compare against later.
- The referral wait, and the possibility of being discharged with reassurance rather than treatment at the end of it.
If your testosterone is 5 nmol/L with symptoms, the NHS will treat you and it will cost you almost nothing. If you're at 10 nmol/L with high SHBG, significant symptoms and a free testosterone calculation nobody has done, the NHS route will most likely end in reassurance. Knowing which of those you are, early, saves months. More on the NHS route in our TRT UK guide.
What the NHS prescribes
NHS guidance describes testosterone replacement being given as an injection or a gel, and in practice the formulary tends toward two options:
- Long-acting testosterone undecanoate injection, given roughly every 10 to 14 weeks at a clinic or GP surgery. It's convenient and it's the standard NHS option. The trade-off is a pronounced peak in the days after the injection and a trough in the final weeks before the next one. Some men are fine on it; others describe the last fortnight of each cycle as a return to how they felt before treatment.
- Daily testosterone gel, applied to the skin. Needle-free and easy to adjust, but absorption varies a lot between individuals, and there's a transference risk to partners and children through skin contact.
What you generally won't get on the NHS is the more frequent, smaller-dose injection schedule most private clinics use (weekly or twice-weekly short-acting esters), which keeps levels flatter between doses. Oral testosterone and hCG to support fertility and testicular function are rarely available. Monitoring, once stable, is typically annual rather than every six months.
NHS vs private TRT, side by side
| Item | NHS | Private |
|---|---|---|
| Cost | Free, standard prescription charge applies | Typically £99 to £200 per month |
| Time to treatment | Several months to over a year | Two to four weeks |
| Diagnostic threshold | Usually requires clearly low results | Grey-zone cases assessed on free testosterone and symptoms |
| Free testosterone measured | Often not | Should be standard |
| Delivery options | Mainly long-acting injection or daily gel | Injections at varied frequencies, gels, creams, oral options |
| Dosing flexibility | Limited | Titrated to your response |
| Monitoring | Typically annual | Every 6 to 12 months, more often during titration |
| Adjuncts such as hCG | Rarely available | Available where clinically appropriate |
| Continuity of clinician | Variable | Usually consistent |
What TRT costs on the NHS versus privately
On the NHS, appointments, blood tests and specialist reviews are free at the point of use. In England you pay the prescription charge, which is £9.90 per item at the time of writing (October 2026), or £32.05 for a 3-month and £114.50 for a 12-month prepayment certificate if you have other prescriptions too. Prescriptions are free in Scotland, Wales and Northern Ireland.
Privately, TRT generally falls between £99 and £200 a month, with most established clinics clustering between £120 and £180, plus initial diagnostics on top. I've broken down the whole market, including a clinic-by-clinic comparison, in how much TRT costs in the UK, and Arc's own plans are on our pricing page.
When private TRT makes sense
I'd never tell a man with clearly low testosterone to bypass the NHS. If your results are unambiguous, go to your GP first. Private treatment makes more sense when:
- Your results sit in the grey zone (8 to 12 nmol/L) or your free testosterone is low with a normal-looking total, and the NHS has told you you're in range
- You've been referred and the wait is many months, and your symptoms are affecting work, relationships or mood now
- You want more frequent dosing, oral options or hCG alongside treatment, none of which are generally offered on the NHS
- You'd rather have the same clinician each time and reviews every few months rather than once a year
Private clinics exist because of the gaps above, not because the NHS is wrong. The differences are speed, protocol flexibility and monitoring frequency. A well-run private pathway still requires two low results before treatment is considered, and from first test to first dose usually takes two to four weeks.
How Arc works alongside NHS care
You don't have to choose one route and abandon the other. A few practical ways the two fit together:
- Start with a proper panel, then decide. Our testosterone blood test measures total and free testosterone, SHBG, LH, FSH, prolactin and oestradiol, reviewed by a GMC-registered doctor. If it shows clearly low results, you can take that to your GP to support an NHS referral. If it shows a grey-zone picture, you'll know why the NHS route may stall.
- Already had NHS bloods? If you have results from your GP taken within the last 6 months, you can send them to us instead of starting from scratch. Choose "I have recent bloods" when you get started and one of our doctors will review them alongside your symptoms.
- Already on treatment and want to move? Our switch consultation reviews your current protocol and recent bloods and continues treatment without restarting.
- The same standards. Arc is a CQC-regulated, doctor-led clinic. Every patient has two blood tests on separate days before treatment is considered, a full consultation with a GMC-registered doctor, and a review at six weeks with repeat bloods, in line with BSSM guidance.
Not sure where your levels sit?
Arc TRT is a UK doctor-led testosterone clinic that has helped over 3,000 men investigate their symptoms and, where appropriate, begin properly monitored treatment. Start with a simple at-home blood test, or send us recent results from your GP.
