All flights operating in airspace designated by the competent authority as a TMZ shall carry and operate Secondary Surveillance Radar (SSR) transponders capable of operating on Modes A and C or on Mode S, unless in compliance with alternative provisions prescribed for that particular airspace by the Air Navigation Service Provider (ANSP).
So in summary, it is not up to the regulator, but the ANSP. If you have SIL = 1 and the ANSP has a suitable ADS-B In capability then it could be very quick indeed!

Gaz,
Bit of wishful thinking going on here , the reference doesn't note even mention ADS-B and "alternate provisions", doesn't translate to ADS-B either.
Are there ay ANSPs in the UK that have specifically stated that ADSB is an acceptable alternative for TMZ entry?
What happens to your Skyecho when the ANSP says they require a minimum of SIL=2 to enter their TMZ under a special provision?
Yes, NATS splashing some cash, but will we get use of whatever system (if any) is implemented.
All beginning to sound similar to the Mode S promises that were made and what a debacle that turned into.
Hope I'm wrong.
