Giving birth in London: maternity survey results by trust

A caesarean section is an operation to deliver a baby through a cut in the tummy and womb. It may be planned, usually from the 39th week of pregnancy, or done in an emergency if vaginal birth is too risky. Around 45% of babies born in England are delivered by caesarean.

Caesarean rates and other birth outcomes for each hospital are published by the National Maternity and Perinatal Audit, but not yet as a file we can use. This page shows how women rated their maternity care in the Care Quality Commission's maternity survey for each trust. Speak to your midwife about where to give birth.

London hospitals

21 London trusts with published figures. Sorted by name. This is not a ranking: read how to read this first.

Hospital-level numbers for this specific operation are not published as open data. The activity column is context only: it shows the trust's overall NHS-funded activity in OPCS-4 chapter R (pregnancy and childbirth) in 2025-26, from Hospital Episode Statistics, in bands. It covers many other procedures as well as this one, it is for the whole trust rather than one hospital, and it does not include private patients. It is not a count of this operation.

Across England

In 2025-26, NHS-funded care in England (NHS hospitals and NHS patients treated by independent providers; private patients are not included) recorded 244,968 episodes where the main procedure was planned and other caesarean deliveries (OPCS-4 R17 and R18). 0% were day cases. Half of the people admitted from a waiting list had waited less than about 15 days from the decision to admit them. These are national figures from Hospital Episode Statistics (NHS England, 2025-26, Open Government Licence v3.0); the same detail is not published for each hospital.

How to read this

  • Not a ranking. The table is in alphabetical order. A higher volume does not on its own mean better care, and we do not combine the columns into a score.
  • Trust activity (Hospital Episode Statistics). The bands show the trust’s overall NHS-funded activity in a whole chapter of the procedure classification (OPCS-4), for context. They are not a count of this operation, they are for the whole trust rather than one hospital, they exclude private patients, and we show bands only, not exact counts. Cut points are the lower quartile, median and upper quartile of all 118 NHS trusts in England with activity in OPCS-4 chapter R in the published table, rounded.
  • Risk adjustment. Where a figure says “adjusted”, the audit has allowed for differences in the patients each hospital treats, such as age and other illnesses. Hospitals that take on more complex cases can still look different for reasons the adjustment does not capture.
  • Bands and limits. We only say a result is higher or lower than expected when the source itself says so (for example NJR outlier status, NELA funnel limits, SSNAP levels, CQC survey bands). Where the source publishes a rate without limits we show the rate and the national figure, and say “No banding published”.
  • Small numbers. A small hospital can have 0% or a high percentage by chance. Figures the source suppresses are shown as “Not published (small numbers)”.
  • Trust or hospital. This audit publishes figures for each NHS trust, which may run several hospitals. The operation may only be done at one of them.
  • Different periods. Each figure has its own period, shown next to it. Audit results describe operations done one to three years ago; waiting times are updated monthly.
  • Talk to your GP or consultant about what the figures mean for you. If you are referred for planned care in England, you can usually choose your hospital.
