The conversation about birth choices in the UK is sometimes framed as a binary between "natural" and "medical" birth, which is not especially useful. What matters is that women have access to accurate information about the options available to them and the evidence on outcomes for those options, so that they can make choices aligned with their circumstances and values.
The NHS duty to inform women about birth settings and to support their choice is clear. In practice, the availability of different settings varies significantly by location — home birth services have been intermittently suspended in some areas during staffing pressures — and NICE guidance acknowledges the tension between what should be available and what is.

Birth Settings in the UK
Obstetric unit (OU): a consultant-led unit within a hospital with 24-hour access to obstetricians, anaesthetists, neonatologists, and operating theatres. Appropriate for women with risk factors including multiple pregnancy, previous caesarean, preterm labour, significant medical conditions, or any high-risk pregnancy feature.
Alongside midwifery unit (AMU): a midwife-led unit in the same building or on the same site as an obstetric unit. Transfer to obstetric care is possible within minutes. Staffed by midwives; medical care available if required. NICE guidelines recommend offering low-risk women the choice of an AMU.
Freestanding midwifery unit (FMU): a midwife-led unit not co-located with an obstetric unit. Transfer to obstetric care requires an ambulance journey, typically 20 to 45 minutes depending on geography. The distance is a factor in decision-making for women who want the option of an FMU.
Home birth: birth at home, attended by midwives. Transfer to hospital requires an ambulance. Not all areas have 24-hour home birth services, and service availability can be intermittent.
The Birthplace Study
The Birthplace in England Cohort Study (Brocklehurst et al., BMJ 2011) followed approximately 64,000 births across different settings. Its findings are the primary evidence base for UK guidance on birth setting choices:
For low-risk pregnancies (no identified risk factors), perinatal outcomes (death or serious morbidity in the baby) were similar across all four settings. Women in midwifery-led settings had significantly lower rates of augmentation, epidural, episiotomy, and caesarean section.
For women having their first baby, home birth carried a slightly higher risk of perinatal complications compared to obstetric units and AMUs (though the absolute risk remained low). For women having subsequent babies (multiparous women), perinatal outcomes were broadly equivalent across all settings.
The higher intervention rates in obstetric units reflect both the higher risk population typically giving birth there and the availability of interventions — it does not mean obstetric units are more dangerous for low-risk women, but it does mean that low-risk women can safely consider other settings.
Birth Plans
A birth plan (or birth preferences document) is a written summary of preferences for labour and birth. Topics commonly covered include: pain relief preferences (including epidural, water, gas and air, opioids), position preferences for labour and birth, wishes for the third stage (oxytocin injection for placenta delivery vs physiological third stage), cord clamping timing (delayed cord clamping is recommended by NICE for all births), skin-to-skin contact, and feeding intentions.
A birth plan does not guarantee specific care. Labour is unpredictable, and clinical circumstances may require departures from stated preferences. Its value is as a preparation exercise (thinking through preferences in advance), as a communication tool (sharing with midwives on the day), and as a framework for informed consent conversations.
NICE NG235 (Intrapartum care, 2023) provides the current guidance framework for labour and birth care.
Pain Relief in Labour
Options in UK hospital and midwifery unit settings typically include: water (bath or pool), TENS machine (transcutaneous electrical nerve stimulation, typically used in early labour), entonox (gas and air, nitrous oxide and oxygen), opioid injections (diamorphine or pethidine), and epidural anaesthesia (the most effective form of pharmacological pain relief, available in obstetric units).
Epidurals are not available in freestanding midwifery units or at home births. A woman who plans to use epidural anaesthesia for pain relief should plan to give birth in an obstetric unit or AMU.
Key Takeaways
Women in England have a legal right to choose where they give birth, including at home. The three main options — obstetric unit, alongside midwifery unit (AMU), and freestanding midwifery unit (FMU) or home birth — differ in their access to obstetric intervention and their associated risk profiles. The Birthplace cohort study (2011, BMJ) provides the most robust UK data on outcomes by birth setting. For women with low-risk pregnancies, midwifery-led settings (AMU, FMU, home) have broadly equivalent perinatal outcomes to obstetric units with lower rates of obstetric intervention. A birth plan communicates preferences but cannot guarantee specific care; its value is primarily in supporting informed decision-making and communication.
