Most gym and health club contracts allow cancellation or suspension on medical grounds, but require a doctor's letter to release you — and many will keep taking payment until they have one.
The letter confirms that a health condition prevents you exercising, and for how long.
Some gyms require a specific form, a minimum period, or notice in a particular format. Send the wording in advance.
The GP establishes what the condition is and whether it genuinely prevents exercise, and for how long.
Within about ten minutes.
Most people who book this have not read the medical cancellation clause, and it is where the whole thing is decided.
Look specifically for:
Send us the wording in advance so the letter addresses their actual criteria.
The letter is dated the day it is written and cannot be backdated to cover payments already taken. Book before the next collection date, not after it — that single point is the difference between one more payment and several.
What the condition is, whether it genuinely prevents exercise rather than making it uncomfortable, and for how long. Expect to be asked what your training actually involves — a shoulder injury may prevent swimming and weights while leaving cycling entirely possible, and an honest letter says so.
A gym is entitled to evidence that you cannot train. It is not entitled to know what is wrong with you. Wherever possible the letter confirms the effect without naming the condition, which is usually sufficient and keeps your medical information yours.
Worth saying plainly: if the real reason is cost, a house move, or simply not going any more, a medical letter is not the route — and the assessment fee applies whether or not one can be written.
Consumer routes exist for those situations and are often more effective. See below.
The letter states what is clinically true. If you are able to exercise, we will not write that you cannot — the assessment fee applies either way.
Whether the gym accepts it is a matter for your contract.
Same day if you can. The letter cannot be backdated, so every day of delay risks another collection.
This is the mistake that causes the most trouble. Cancelling the payment before the gym has accepted the cancellation puts you in arrears rather than out of contract, and some clubs pass that to a debt collection agency.
Wait for written confirmation that the membership has ended, then cancel.
Ask for the refusal in writing with the contractual reason. Then, in order:
Where the problem is temporary, suspension is frequently easier to obtain than cancellation and preserves your joining terms. Many contracts allow it explicitly, and a letter supporting a defined freeze period is usually accepted more readily than one supporting full release.
Ask during the consultation what you can do in the meantime rather than nothing at all. Most conditions that prevent one kind of training permit another, and staying active where you safely can is usually better for recovery than a complete stop.
What we will and will not write. The letter states the condition, that it prevents exercise, and the period involved. We will not write that a condition is permanent when it is not, and we will not give an open-ended date to make a cancellation easier. An overstated letter is the kind that gets challenged.
You do not have to disclose more than necessary. A gym is entitled to evidence that you cannot train; it is not entitled to your diagnosis. Where possible we word the letter to confirm the effect without naming the condition, which is usually enough and keeps your medical information yours.
This is not a route out of a contract you no longer want. If the reason is cost, a house move, or simply not going any more, a medical letter is not the answer, and the assessment fee applies whether or not we can write one. Consumer routes exist for those situations — check the contract terms and the gym's own cancellation policy first.
Timing matters more than people expect. The letter is dated the day it is written. We cannot backdate it to cover payments already taken, so send it before the next collection date rather than after.
No — and this is worth knowing before you pay. Whether a medical letter releases you is governed by your contract, not by the letter.
Most contracts do allow medical cancellation, but on their terms: typically requiring the condition to prevent exercise for a minimum period, commonly three months. A letter confirming a shorter or intermittent problem will not meet that, however genuine it is.
Read the clause before booking.
No. The letter states what is clinically true, including the realistic duration. We will not describe a temporary condition as permanent or leave the end date open to make a cancellation easier.
That is not obstruction — an overstated letter is precisely the kind that gets challenged, and a gym that queries it will be querying a document with a GMC number on it.
Not if you would rather it did not. A gym is entitled to evidence that you cannot train; it is not entitled to your diagnosis.
Wherever possible the letter confirms the functional effect and the period without naming the condition. Say so during the consultation.
Not with a medical letter, and the assessment fee would still apply. We would rather tell you that now than take £40 for a consultation that cannot produce what you need.
The better routes are consumer ones. Under the Consumer Rights Act 2015 a term creating a significant imbalance against the consumer may be unfair and unenforceable, and long minimum terms with no exit have been challenged successfully. Citizens Advice will help with this free of charge.
Not until the gym confirms in writing that the membership has ended.
Cancelling the payment first puts you in arrears rather than out of contract, and some clubs refer that to a debt collection agency. It is the single most common way a straightforward cancellation becomes a difficult one.
Often, and it is frequently the easier outcome. Suspension is usually granted more readily than release, it preserves your joining rate, and many contracts allow it explicitly on medical grounds.
If the condition is temporary, that is usually the sensible ask.
No. The letter is dated the day it is written and records what was assessed on that date. It cannot cover a period nobody assessed.
This is why timing matters — book before the next collection rather than after several have gone out.
Then the letter will say so, and that is the honest position. A shoulder injury may prevent swimming and weights while leaving cycling perfectly possible.
That may not release your contract — but it is usually better for your recovery to keep doing what you safely can, and it is worth asking what that is during the consultation.

Same-day access is usually available, from 6am to 10pm, seven days a week. You choose a time that suits you rather than waiting on hold at 8am.
Yes. Care is led personally by Dr Mohammad Khan, so you are not passed between clinicians. Continuity is the point of a small practice: someone who knows your history and is listening attentively rather than working through a checklist.
Yes, with your consent. We can access your Summary Care Record during the consultation, so your current medications, allergies and significant history are in the room. That means fewer questions you have already answered elsewhere, and safer prescribing.
No. We are not here to replace GPs, only to support them. Your NHS practice remains responsible for your ongoing care, and with your consent we write to them after the consultation. We are useful when you need to be seen sooner, or want more time than a standard appointment allows.
Twenty unhurried minutes and a comprehensive assessment. A written treatment plan is included, along with any prescription, sick note or referral letter arising from the consultation, at no extra charge.
£40 for 20 minutes, self-pay. Membership is optional and never required. Priced for fairness, because we are not here to charge extortionate amounts for access to a doctor.
It means the diagnosis can usually be made from your history and photographs, and that treatment can be arranged safely without examining you. Where a condition is not marked treatable online, it is because examination is the diagnosis — listening to a chest, feeling an abdomen, examining an ear or a joint — or because a procedure or device is needed.
Yes, where there is a genuine bacterial infection — cellulitis, impetigo, bacterial urine infections, confirmed strep throat. We will also frequently tell you that you do not need one. Most sore throats, coughs, colds and earaches are viral, and an antibiotic gives you the side effects with none of the benefit.
If your problem turns out to be genuinely outside what we can do remotely, the doctor will tell you straight away, point you to the right service, and refund your fee in full. We would rather do that than fill twenty minutes to justify the charge.
Call 999 or go to A&E — do not book an online appointment and do not wait for a reply to an email. For urgent problems that are not emergencies, NHS 111 is available 24 hours a day, online or by phone, and can direct you to the right service.
