Only for IMC holders when IFR in Class D or G airspace. For IR holders IFR in class A airspace minima is procedure minima/company minima/absolute minima but only if there is a published procedure. For IR or IMC holders SVFR in Class A and D minima is 3km, see Schedule 8 and any 'notifications'.
3km is required in London CTR within Fairoaks, Denham and White Waltham Local Flying Areas. See ENR 1-4-2 2.1.1.1 para (vii)(a). It is a 'notification', ie. a 'special concession' within the London CTR Class A airspace and should not be abused, as it often is.
