The route to emergency contraception in England has changed materially over the last 18 months. A service once largely funded by local authorities and delivered through sexual health clinics has moved decisively into the community pharmacy, where the majority of users now access it, often free on the NHS.
This guide covers the current picture in 2026: the two main medicines, the time windows, what the free NHS supply covers, and how to find a participating pharmacy.
The two medicines
Two oral emergency contraceptive medicines are licensed in the UK:
| Medicine | Brand names | Time window | Mechanism |
|---|---|---|---|
| Levonorgestrel 1.5mg | Levonelle, ellaOne generic, own-brand | Up to 72 hours after unprotected sex | Delays or prevents ovulation |
| Ulipristal acetate 30mg | ellaOne | Up to 120 hours after unprotected sex | Delays ovulation; more effective later in cycle |
Both work by delaying ovulation so that any sperm already present cannot meet an egg. Neither is abortive — they do not terminate an established pregnancy. Ulipristal acetate is more effective than levonorgestrel closer to the time of ovulation, which is why it is often preferred when the timing of the menstrual cycle is uncertain or close to mid-cycle.
A copper intrauterine device (IUD) is the third option and the most effective form of emergency contraception, effective up to five days after unprotected sex or up to five days after the earliest likely date of ovulation. The IUD is fitted at a sexual health clinic or general practice, not at a pharmacy.
The consultation
A pharmacy emergency contraception consultation is structured. The pharmacist will check:
- Time since the episode of unprotected sex
- Stage of the menstrual cycle where the woman knows it
- Other medicines, particularly enzyme inducers like carbamazepine, phenytoin, rifampicin and St John's Wort, which reduce levonorgestrel effectiveness
- BMI, because levonorgestrel is less effective in women with BMI over 26
- Previous use of ulipristal acetate in the same cycle, which affects further supply
- Safeguarding for very young patients — under-16 consultations follow Gillick/Fraser guidelines
The consultation is private and confidential and takes around 10–15 minutes.
Free NHS supply in 2026
The Pharmacy Contraception Service, expanded in 2024 and now operating across almost all English community pharmacies, includes emergency hormonal contraception as one of its covered supplies. Eligible patients can receive the medicine free of charge without needing a prescription — the pharmacy is paid directly by the NHS for the consultation and the product.
Eligibility is straightforward: the patient must be a resident in England, the clinical criteria must fit, and the consultation must be completed in person. The cost of over-the-counter private purchase of ulipristal acetate from a UK pharmacy is typically £25–£35 and levonorgestrel £15–£25, so the NHS pathway is a meaningful saving.
Not every pharmacy has signed up to the advanced service. Coverage is high in urban areas, lower in rural ones. A pharmacy that has not signed up can still supply emergency contraception privately but cannot provide it free on the NHS.
What about Scotland, Wales and Northern Ireland?
Scotland provides emergency contraception free at participating community pharmacies through the NHS Pharmacy First Scotland service. Wales provides free emergency contraception via the Common Ailments Service and direct supply through community pharmacies. Northern Ireland has a Pharmacy First scheme that includes emergency contraception in most health and social care trust areas.
The branding differs but the principle is the same: free, confidential supply from a community pharmacy in most of the UK.
The time windows in practice
The 72-hour and 120-hour windows are from the episode of unprotected sex, not from when symptoms appeared. Effectiveness drops over time — both medicines work better the sooner they are taken. The standard advice is to access supply on the same day or the next morning where possible rather than waiting.
If both windows are missed, the copper IUD remains an option up to five days after unprotected sex or up to the earliest likely ovulation date. Sexual health clinics can advise and fit.
What the pharmacy consultation is not
The consultation is about supply of emergency contraception. It is not a general sexual health assessment, and a separate appointment with a sexual health service is the right place for:
- Testing for sexually transmitted infections
- Starting long-acting reversible contraception (coil or implant)
- Post-exposure prophylaxis for HIV, which has its own urgent pathway through A&E or sexual health clinics
A pharmacist will signpost to those services during the consultation where appropriate but they are not themselves provided at the counter.
Follow-up
All emergency contraception users are advised to take a pregnancy test if the next expected period is more than a week late or is lighter than usual. The medicine can sometimes shift the timing of the next cycle by a few days in either direction.
Women who find themselves accessing emergency contraception more than occasionally benefit from a conversation about regular contraception — the advanced pharmacy service now includes ongoing contraception supply for some methods, and sexual health clinics and GPs offer the full range.
Finding a participating pharmacy
PharmSee's pharmacy finder lists community pharmacies by postcode with opening hours and chain. Sunday opening, late-night opening and participation in the advanced service vary by site, which matters because the 72-hour and 120-hour windows can fall across weekends when GP access is restricted.

Caveats
The service structure described reflects NHS England advanced service commissioning as of April 2026. Pharmacy participation is voluntary and coverage is not universal, so individual participation should be checked with the specific pharmacy or the NHS.uk service finder. Clinical eligibility criteria are subject to change as the clinical pathways are updated.
