Switch medical aid: transfer letter template and how to avoid waiting periods
By MedicalAidZA editorial team · 5 min read · Updated 29 September 2026

- Waiting periods (maximum)
- Up to 3 months general and 12 months condition-specific
- Gap threshold
- 90 days without cover
- Late joiner age
- 35 or older on application
- CMS Open Season 2026
- Finalise switch decisions by late November or early December
To switch medical aid without losing cover, get the new scheme's start date in writing, then ask the old scheme to end your membership the day before and to issue a membership certificate. The copy-paste letter is below.
The certificate is your proof of past cover. The new scheme uses it to decide whether waiting periods or a late joiner penalty apply. Never cancel the old scheme before the new cover is confirmed.
There is no need to guess at the rules: the table below sets out the maximum waiting periods for each kind of switch.
When to use this letter
Use it when you are moving to a new scheme, or a new option in another scheme, and want the old scheme to end your cover on a set date and give you proof of it. It suits an annual switch, a job change, or a move to an employer's scheme.
To pick a scheme, compare plans first with how to compare medical aid plans. Switching within the same scheme, between options, is a different rule, covered below. The changing medical aid guide has the full order of steps.

Dear Sir or Madam
I am moving to [NEW SCHEME NAME] with effect from [NEW START DATE]. Please cancel my membership, and that of my dependants listed below, with effect from [LAST DAY OF COVER, THE DAY BEFORE THE NEW START DATE].
[MAIN MEMBER: FULL NAME AND ID NUMBER]

2. That you will issue a membership certificate showing my start date, my end date, each beneficiary's cover dates and any waiting periods still running or already served.
3. Whether any amount is owing by me or to me, and how my medical savings balance will be handled.
4. Any [late joiner penalty](/guides/late-joiner-penalty/) recorded against me or my dependants.

Yours faithfully

What waiting periods can apply when you switch
The law caps waiting periods. These are maximums, and a scheme may impose less or none.
| Your situation | Most the new scheme can impose |
|---|---|
| Not on a scheme for 90 days or more before applying | Up to 3 months general and up to 12 months condition-specific |
| Covered up to 24 months, gap under 90 days | Up to 12 months condition-specific, not for PMB treatment, plus any unexpired waiting period from the old scheme |
| Covered for more than 24 months, gap under 90 days | Up to 3 months general, not for PMB treatment |
| Gap under 90 days, and the move is because you changed jobs or your employer changed or ended its scheme | No general or condition-specific waiting period |
| Changing options within the same scheme | None, unless a waiting period is still running on the current option |
Do not read this as "switch within 90 days and there are no waiting periods". That is only true in the job or employer cases. The waiting periods guide explains each row.
The scheme can ask for a medical report only about a condition that had advice, diagnosis, care or treatment in the 12 months before you applied.
What to attach and send
- The new scheme's written confirmation of your start date, so you can check the two dates line up.
- A copy of your ID.
- The list of dependants, with ID numbers.
Send the letter only after the new scheme has confirmed cover. Ask the new scheme when it wants the certificate.
How to send it and keep proof
Email the letter to the membership address on the old scheme's website or statement, and save the sent copy with its date and time. Ask for a reference number. Use registered post if you post it. Keep the new scheme's acceptance and the old scheme's confirmation together in one folder.
Then check that the old debit order stops after the final contribution and that the new one starts on the right date.
What happens next
We found no national deadline for the old scheme to issue the certificate, so ask for a date in your letter and follow up in writing. If it does not respond, use the complaint letter, and ask the Council for Medical Schemes for advice on 0861 123 267.
Late joiner penalties can follow you to the new scheme. If you were penalised before and can later prove earlier cover, the new scheme must recalculate the penalty from the date the proof is produced, and a sworn affidavit is enough if documents cannot be obtained. See the late joiner penalty guide.
Chronic cover: we found nothing saying chronic registrations move with you, so register again on the new scheme using the chronic medication letter. The CMS suggests checking what late joiner penalties or waiting periods apply before joining a new scheme.
Common mistakes
- Cancelling before the new cover is confirmed in writing.
- Choosing an end date that leaves a gap, or overlaps so you pay twice.
- Not asking for the membership certificate.
- Believing a gap of under 90 days always means no waiting periods.
- Forgetting to register chronic medicine again.
- Ignoring your savings balance. See the savings account letter.
Frequently asked questions
How do I switch medical aid without waiting periods?
Move with no gap and give the new scheme proof of past cover. A move within 90 days after a job change or an employer changing scheme carries no waiting period. In other cases a scheme may still impose a limited one.
Is there a best time of year to switch?
The CMS advises finalising switch decisions by late November or early December during Open Season. Check the start dates each scheme offers and how much notice your old scheme needs.
Do my chronic registrations move with me?
We found nothing saying they do. Register again with the new scheme, with a script and ICD-10 code, once the cover starts.
Will switching cost me a late joiner penalty?
A penalty applies to someone aged 35 or older at application who cannot show enough creditable cover. Penalties can follow you to a new scheme. Ask the new scheme in writing whether one applies.
What is the most important document when switching?
The membership certificate from the old scheme. It shows your cover dates and waiting periods served.
What if there is a gap between the old and new cover?
A gap of under 90 days can still carry a condition-specific or general waiting period. A gap of 90 days or more can carry both, up to their maximums.
