How to switch TRT clinics in the UK without a gap in treatment
You can usually change TRT clinic without stopping treatment. Start before you run low, gather three documents, and let the new clinic review them before you pay anything. A doctor agrees your plan; only then give notice to your old clinic.
Most men change TRT clinic for unglamorous reasons. The bill crept up. The doctor they first saw became a support inbox. A routine renewal started taking a week.
None of that is a reason to stay put. The real worry is a gap in treatment while the new clinic decides. The answer is planning, not haste.
Can you switch without stopping treatment?
Usually, yes. A new clinic does not normally need you to stop and start again. It does need enough information to prescribe safely: your original diagnosis, your current plan and recent safety bloods.
GMC guidance requires a prescriber to have adequate information about a patient first, which is why a responsible clinic will not simply copy your old prescription.
The rule: start well before you run low, and keep following your current prescriber's instructions until the new one confirms in writing that they are taking over.
The three documents you need
| Document | What it should show |
|---|---|
| Original diagnostic bloods | Results from before you started, with dates, units and reference ranges |
| Current prescription or clinic letter | What you take, how much and how often |
| Recent monitoring bloods | Ideally a full panel from the last six months, including full blood count, PSA, liver and kidney markers |

If your clinic is slow to hand these over, you are entitled to them. A subject access request under UK data protection law is usually free and must be answered within one calendar month (extendable in some cases).
How switching works at Harrington
You pay nothing until a doctor has agreed you are suitable.
- Enquire. Tell us where you are now and roughly how much supply you have left. A member of our patient support team replies personally.
- Clinical review. Upload your records through our secure portal. A doctor checks whether they are enough or whether a top-up test is needed. We come back to you within two working days of receiving everything.
- Doctor consultation. Once approved, you book a free 30-minute video consultation with a GMC-registered doctor who has read your notes.
- Handover. If treatment continues, your prescription can often be issued straight after the consultation, timed around your remaining supply.
Some services handle transfers by reviewing paperwork in the background and sending back a decision. That can be efficient, but a switch is often the first time in months you have questions for a doctor. A conversation is the place to ask them.
If your bloods are out of date
If your last panel is more than six months old or missing key markers, our Enhanced Blood Test covers more than 50 markers from one venous sample, analysed by a UKAS-accredited laboratory, for £99. Collection is free through your GP or own clinic, £45 at a partner clinic or Superdrug, or £65 for a home nurse.
What it costs once you have switched
You choose a plan with your doctor after the consultation.
| Core | Concierge | |
|---|---|---|
| Price | £24 a month or £240 a year | Injectable plans from £99 a month |
| Medication | Ordered separately through our nominated pharmacy partner | Included and delivered |
| Monitoring bloods | Booked and paid per test when due, usually twice a year once settled | Laboratory analysis included, reviewed by your named doctor |
| Your people | Named doctor and our patient support team | The same named doctor throughout, plus a named case manager |
| Best for | Stable patients who want to run their own treatment | Men who want everything handled for one fee |
The type of medication you are prescribed is agreed with your doctor, based on your discussion and your preferences. On both plans a doctor review call costs £49 whenever you want one, blood collection is charged separately, and there is a six-month minimum term, then monthly with 30 days' notice. Our TRT cost guide sets out a full first year and compares it with your current clinic.
Costs to check before you leave
Compare the next 12 months, not the headline fee. Ask your current clinic, and any new one, about:
- consultation or renewal fees charged per prescription;
- how often monitoring bloods are needed, and who pays for collection;
- delivery and prescription fees;
- the minimum term and notice period, so you are not paying two clinics at once.
Choosing between clinics? Our eight questions to ask any TRT clinic apply to us too.

Questions men ask
This article is general education, not a diagnosis. Reading it does not confirm a condition or guarantee that treatment is suitable for you — that always requires blood tests and an assessment with a clinician.
