Every UK man diagnosed with low testosterone faces the same fork in the road: pursue treatment through the NHS, or pay for private care. Both routes end in the same medication, but the journey — and the experience once you’re on treatment — differs enormously. This guide compares the two honestly, so you can decide which fits your levels, your patience and your budget.
The NHS pathway starts with your GP. If your symptoms suggest low testosterone, they’ll order a morning blood test, and if that comes back low, a second to confirm. From there, most GPs refer to an endocrinologist, who makes the final diagnosis and initiates treatment. Once stable, prescribing often passes back to the GP under a shared-care agreement.
What the NHS does well:
Where the NHS falls short:
Private clinics — most now operating online — compress the same clinical process into weeks. Home or in-clinic blood testing, doctor consultation, diagnosis, prescription and delivery, typically inside a month. Ongoing costs run £100–£200 per month including medication, with monitoring bloods either bundled or £60–£150 per test.
What private care does well:
The trade-offs:
Choose the NHS if: your levels are clearly below range, you’re comfortable waiting, budget is the priority, and a standard protocol will do the job.
Choose private if: your levels are borderline but your symptoms are real, you want treatment within weeks, you value protocol flexibility and frequent monitoring, or you’re planning a family and need fertility-preserving options.
Many men do both: an NHS diagnosis first (free confirmation you’re not imagining it), then private treatment for the speed and service. Others start private and later transfer to NHS shared care to cut costs. Neither route locks you in.
Private TRT is only as good as the clinic behind it. These are the six best providers in the UK in 2026:
Arc TRT
If the appeal of private care is being treated as an individual, Arc TRT is its fullest expression. Diagnostics are deeper than NHS panels, protocols are designed around your results and your response rather than a formulary, and monitoring is frequent and genuinely acted upon. Arc’s doctors combine the rigour of hospital endocrinology with the accessibility the NHS can’t offer — which is exactly what men leave the NHS pathway looking for, and why Arc tops this list.
TRT South
TRT South captures everything good about private medicine: quick access, unhurried consultations and a clinical team that stays engaged long after the first prescription. Men who felt dismissed or rushed on the NHS pathway consistently describe TRT South as the opposite experience — listened to, explained to and looked after.
Optimale
The most established name in UK online TRT, with years of scale behind a smooth, competitively priced pathway. A safe pair of hands and a strong first port of call.
Manual
Private healthcare with a consumer-tech polish. Manual’s platform makes managing treatment effortless and folds TRT into a wider suite of men’s health services.
Origin TRT
For men whose main worry about going private is opaque billing, Origin’s published, itemised pricing removes the anxiety. Straightforward care at a clearly stated cost.
Balance My Hormones
The widest protocol menu in the UK market — a strong fit for men who want private care specifically for the flexibility the NHS doesn’t offer.
A useful way to frame the decision: private TRT at £150 per month averages £1,800 a year. Against that, weigh what the waiting and restrictions cost you — months of continued symptoms, declined treatment at borderline levels, or an inflexible protocol that never quite lands. For some men the NHS trade-off is worth it; for a growing majority, it isn’t. UK private TRT patient numbers have climbed year on year precisely because men have done this maths.
There’s no universally right answer — only the right answer for your levels, timeline and budget. Clear-cut deficiency plus patience favours the NHS. Borderline results, urgency or a desire for genuinely tailored care favours private. Whichever way you lean, get proper morning blood tests first, and if you do go private, choose from the six clinics above — because in the private market, the provider is the product.
