Free NHS prescriptions and dental care calculator
Enter your due date or your baby's date of birth and the tool dates the maternity exemption certificate, which runs for twelve months. It also shows what the certificate is actually worth where you live, because prescriptions are already free outside England.

FormulaHow the dates and the value are worked out
The certificate
The maternity exemption certificate — the MatEx — is applied for on form FW8, signed by a midwife, GP or health visitor, and issued by the NHS Business Services Authority. It entitles you to free NHS prescriptions and free NHS dental treatment.
The dates
expires = due date or date of birth + 12 months
In practice that is the baby's first birthday. The certificate is issued during pregnancy and runs through the whole of the first year.
The value
prescription saving = expected items in the year × the English prescription charge per item
That line only produces a number in England. NHS prescriptions are already free for everyone in Scotland, Wales and Northern Ireland, so the prescription half of the certificate saves nothing there. The free NHS dental treatment half is worth having in all four nations.
The English prescription charge is reviewed each April, so the tool lets you enter the current figure rather than baking in one that will drift out of date.
What the tool does not do
It names no medicine and no amount — the prescription charge is an administrative figure, not a clinical one. It does not model NHS dental treatment bands, which are set separately in each nation, and it does not calculate whether a prescription prepayment certificate would be cheaper once the exemption ends.
An entitlement that has to be asked for
Free NHS prescriptions and free NHS dental treatment in pregnancy and for a year afterwards are not automatic. They depend on a maternity exemption certificate, which has to be applied for on a form your midwife, GP or health visitor signs, and which the NHS Business Services Authority then posts out.
Plenty of people never get one, because nobody mentioned it at the appointment where it should have come up. They then pay for dental treatment they were entitled to receive free, and in England pay prescription charges they did not owe. Ask at your booking appointment, and ask again if the certificate has not arrived within a few weeks.
The date is a cliff, not a slope
The certificate runs for twelve months from the due date or the birth — effectively to the baby's first birthday. There is no taper and no grace period. On the day after it expires you are back to paying whatever everyone else pays.
For dental treatment this needs planning rather than remembering. A course of treatment generally has to be started while the certificate is valid, and a course is not a single appointment: a check-up leads to a treatment plan, and the treatment then has to be booked. Practices are busy. If there is work you have been putting off, the sensible move is a check-up two or three months before the expiry date, not two weeks before.
What it is actually worth depends on where you live
This is the part that surprises people who have moved. NHS prescriptions are free for everyone in Scotland, Wales and Northern Ireland. In those three nations, the prescription half of the maternity exemption certificate saves you precisely nothing, because you were never going to be charged.
In England, prescriptions carry a per-item charge that is reviewed every April, and the saving is real. A year that includes iron, a course or two of antibiotics, treatment for thrush or mastitis, and anything ongoing can easily run to a dozen items or more. Multiply that by the current charge and the certificate is worth having for that reason alone.
Free NHS dental treatment, by contrast, is worth having everywhere. Dental charges are not trivial in any of the four nations, and a course of treatment can run into hundreds of pounds.
Pregnancy is a good time to see a dentist anyway
Beyond the fact that it is free, there are reasons the dental entitlement exists. Hormonal changes in pregnancy make gums more prone to inflammation and bleeding — pregnancy gingivitis is common and usually settles afterwards, but it responds well to being looked at. Vomiting in early pregnancy exposes teeth to stomach acid repeatedly, which is hard on enamel.
Dentists see pregnant patients routinely. Tell them you are pregnant and roughly how many weeks, and let them decide what to do and when. Some treatments are more comfortable in the second trimester than the third, and lying flat for long periods becomes less pleasant later on. Those are scheduling decisions, not reasons to stay away.
When the certificate runs out
In England, if you still need regular prescriptions after the first birthday, look at a prescription prepayment certificate straight away. It caps what you pay across three or twelve months and pays for itself at a fairly low number of items. It is an entirely separate scheme, it does not roll on automatically from the maternity exemption, and nobody will prompt you.
There are also other routes to free prescriptions that may apply: certain benefits, certain medical conditions, and being under 16 or over 60. The NHS help with health costs pages set out the full list, and it is worth a look rather than an assumption.
If the pregnancy does not end the way it should have
The certificate is not withdrawn if the pregnancy ends in a loss or if the baby dies. Nobody should have to ask about that at such a moment, and if a certificate is refused or cancelled on those grounds it is worth challenging with the NHSBSA rather than accepting it.
What this page will not give you
No medicine names and no amounts appear here. The prescription charge is an administrative figure — a fixed fee per item that has nothing to do with what the item is or how much of it you are given. What you are prescribed and how much is a matter between you and whoever is prescribing, and this page is not the place for it.
What the tool does is take a date and turn it into a deadline, then turn a per-item charge into a number worth looking at. Both of those are arithmetic, and both are things the paperwork itself never tells you.
The certificate is not the only help available
The maternity exemption certificate sits alongside several other entitlements that arrive on their own timetables and are applied for separately. The Healthy Start card, or Best Start Foods in Scotland, covers milk, fruit, vegetables, pulses and formula, and also provides free vitamins for pregnancy, breastfeeding and young children. The one-off maternity grants close six months after the birth. Child Benefit backdates only three months. None of them is triggered by the exemption certificate and none of them prompts the others, so working through the list once, deliberately, in the first month is worth more than reacting to whichever leaflet happens to appear.
The short version
Apply for the certificate at booking. Check it has arrived. Book a dental check-up in the first half of the year rather than the last month. If you are in England, notice what you are not paying and consider a prepayment certificate before the exemption ends. And put the expiry date somewhere you will see it, because nothing in the system will remind you it is coming.
