UK circumcision is ~16–21% overall and strongly concentrated in religious minorities

National probability surveys put male circumcision in Britain at roughly 16–21% (Natsal-2 2000: 15.8% of men 16–44; Natsal-3 2010–12: 20.7% of men 16–74). It is strongly concentrated by religion: ~85–88% of Muslim men and (per a WHO estimate) ~99% of Jewish men, versus ~12–16% of White-ethnicity men.

Figures shift by denominator (age band, sexually-experienced vs all men, religion vs ethnicity); the latest national data is Natsal-3 (2010–12). The ~99% Jewish figure is a WHO estimate, not a UK survey.

UK circumcision is lawful via common law, with Re B and G the leading touchstone

Non-therapeutic male circumcision is lawful in the UK with parental consent under common law, not statute, if competently performed and in the child’s best interests. In Re B and G (Children) (No 2) [2015] EWFC 3, Sir James Munby P held it can amount to "significant harm" yet remain within "reasonable parenting" — categorically distinct from FGM, which can never be reasonable parenting.

The circumcision/FGM comparison in Re B and G is widely read as obiter dicta (the case concerned FGM) — persuasive, not binding ratio; there is no governing statute.

The BMA takes no position and the NHS does not fund routine circumcision

The British Medical Association’s 2019 guidance takes no position on the acceptability of non-therapeutic male circumcision but requires parents to demonstrate it is in the child’s best interests; the NHS provides circumcision only for medical indications (e.g. pathological phimosis), not routine or religious circumcision.

The UK is a low-prevalence HIV country that does not use circumcision for prevention

The UK is a low-prevalence, low-incidence HIV country — 3,043 new diagnoses in 2024 (down 4% on 2023, UKHSA) — with a prevention strategy built on PrEP (111,123 people in 2024), testing and treatment-as-prevention. Circumcision appears nowhere in the UK HIV strategy, consistent with WHO recommending VMMC only in high-prevalence settings.

"New diagnoses" is epidemiologically distinct from incidence and excludes people previously diagnosed abroad; the low/declining thrust holds.

Routine UK circumcision collapsed after the NHS declined to fund it in 1949

UK circumcision prevalence rises with age (Natsal-3: 12.8% at 16–24 up to 34.5% at 65–74), reflecting a historical decline: routine infant circumcision fell from roughly half of working-class newborns to under 1% by the early 1960s after the NHS (founded 1948) declined to fund it, influenced by Gairdner’s 1949 "Fate of the Foreskin" paper documenting deaths from the procedure.

The surveys did not record age at circumcision, so the cohort/historical explanation is inferential from the age gradient.
