This article was written when England had 42 Integrated Care Boards (ICBs). Following NHS reorganisation in April 2026, the number reduced to 36 ICBs. A further round of mergers is planned for April 2027, which will reduce the total to approximately 26. ICB boundaries, names, and commissioning policies may have changed since publication. Always verify your ICB and its current fertility policy directly at NHS England — Integrated care in your area.
If you have ever tried to find a simple answer to "what is the NHS age limit for IVF," you have probably found the question surprisingly hard to answer. That is because there is no single national age limit. Each of England's Integrated Care Boards sets its own thresholds, and those thresholds vary — sometimes considerably — from one area to the next.
This guide explains how ICB age policies work, what the range looks like across England, and what your options are if you are approaching, at, or just past a regional upper age limit.
What NICE Actually Recommends
NICE Guideline NG65 is the starting point for most ICB age policies. It recommends:
- Women under 40: offered up to three full IVF cycles if they meet clinical criteria
- Women aged 40–42: offered one cycle of IVF if they have not previously had IVF, have no known low ovarian reserve, and are aware that success rates are lower at this age
NICE does not recommend funding IVF for women aged 43 or over using their own eggs. This is a clinical recommendation based on HFEA outcome data showing a steep decline in live birth rates with age, particularly from the woman's own eggs.
What ICBs do with this recommendation is up to them.
Why Age Limits Differ Between ICBs
ICBs are responsible for commissioning NHS services within their area and are under significant financial pressure. Some have adopted the full NICE recommendation (funding up to age 42 under the right conditions), while others have set a lower upper limit — typically 35, 37, or 39 — to reduce demand.
A smaller number of ICBs have historically applied lower minimum ages or have additional requirements for women approaching the upper threshold (for example, requiring that investigations are completed and a referral has been made before a certain age, even if treatment does not begin until after that date).
The result is that two women in identical clinical situations, living 20 miles apart, may have very different NHS IVF entitlements based solely on which ICB covers their postcode.
The Pattern Across England
While policies change regularly and individual ICB documents are the authoritative source, the following pattern is broadly consistent:
Upper limit at 42 (NICE-aligned): A number of ICBs fund one cycle for women aged 40–42 who meet clinical criteria, in line with NICE NG65. This is more common in ICBs with larger budgets or those that have recently reviewed their policies.
Upper limit at 39 or 40: Several ICBs draw the line at 39 or 40, either because they fund fewer total cycles or because they do not extend funding beyond the under-40 recommendation.
Lower upper limits (35–37): Some ICBs — particularly those that fund only one cycle — have historically applied lower age limits, or apply the same age limit across all cycles regardless of cycle number.
Age at treatment vs age at referral: This distinction matters. Some ICBs define eligibility by the woman's age when referred; others by her age when treatment starts; and others by her age at egg collection. A patient who is referred at 39 but begins treatment at 40 may find herself outside the funded age window depending on how her ICB's policy is worded.

Single Women and Same-Sex Couples: Age Limits Apply Too
The age limits that apply to heterosexual couples also apply to single women and same-sex female couples, where those groups are included in a commissioning policy at all. For a full explanation of how eligibility works for these groups, see our guides on single women and NHS IVF and LGBTQ+ couples and NHS IVF eligibility.
If You Are Approaching the Upper Age Limit
Time is the most important variable in this situation. The steps to take are:
Ask for a referral now. Do not wait until you have "tried long enough." If you are in your late thirties and approaching your ICB's upper age limit, ask your GP for a fertility referral immediately. Waiting lists at NHS fertility units can be three to six months or longer.
Check the exact wording of your ICB's policy. The policy document will specify whether the age limit applies at referral, at treatment, or at egg collection. This distinction can make a significant practical difference.
Ask whether partial treatment before the deadline qualifies. Some ICBs will fund a complete cycle that begins (with stimulation) before the cut-off date, even if egg collection or transfer happens after. This is worth clarifying explicitly with the fertility unit.
Know your right to appeal. An age-based refusal where the policy is ambiguous or out of date is challengeable. For a detailed guide to the NHS complaints and IFR process, see how to appeal an NHS IVF refusal.
Over the Age Limit: Private Treatment
If you have passed your ICB's upper age limit — or if your ICB does not fund IVF for your age group — private treatment remains an option. The financial planning considerations are significant, and the costs involved in multiple cycles, particularly with donor eggs (which become statistically relevant in your early to mid-forties), require careful budgeting.

Check Your ICB's Current Age Policy
NHS IVF age limits change as commissioning policies are reviewed. What was accurate in a forum post from two years ago may not reflect your ICB's current position.

Frequently Asked Questions
Q: Is there a national NHS age limit for IVF?
A: No. NICE Guideline NG65 sets out clinical recommendations (up to age 42 for one cycle, under 40 for up to three cycles), but each ICB sets its own policy. Some follow NICE exactly; others apply lower age limits. The only way to know your limit is to check your ICB's current commissioning document.
Q: If I am referred before the age limit but treatment starts after, am I still eligible?
A: It depends on how your ICB's policy defines the relevant date — referral, treatment start, or egg collection. You must check your specific ICB's wording. This is worth asking explicitly at the point of referral.
Q: My GP says I am too old for NHS IVF. Should I accept that?
A: Ask your GP to show you the written commissioning criteria. If you are within the age range specified in the current ICB policy, the GP's assessment may be incorrect or based on outdated information. GPs do not always have current knowledge of commissioning policy details.
Q: Can I get NHS IVF with donor eggs if I am over 42?
A: Treatment with donor eggs is a different pathway from standard IVF, and commissioning policies vary on whether donor egg IVF is funded at all — and if so, whether the age limits differ. Some ICBs apply different age ranges for donor egg cycles. Check your ICB's current policy specifically for donor egg IVF.
Q: Does the age limit apply to my partner or only to me?
A: Age criteria in most ICB policies refer to the woman's age (or the egg provider's age in donor egg cycles). Male partner age is occasionally addressed separately, but it is rarely the primary threshold. Check your ICB's policy for the specific criteria that apply.
