I think most if not all Councils have stopped taking any new appointments for NCS + JCAP together. If you made your booking in advance, they will continue to honour those.
There is now 3 options (though not all council yet offer this)
1. NCS Only - This is where you take the Paper application for Naturalisation to them along with supporting docs
2. NDRS Only - This is where you apply online, but take supporting docs for them to photocopy and send
3. JCAP - This is NDRS and the Paper Passport application together now.
It's explained here quite well:

Councils that offer NCS don't all offer the NDRS or the new JCAP yet. I rang some places up that are listed
https://www.gov.uk/government/publicati ... ce-england , but they said they didn't offer NDRS/JCAP yet but might in future (staff need training etc).
Some council websites haven't been updated to say they do offer NDRS. e.g. I got an appointment at Sheffield register office, on their website there's no mention of NDRS/JCAP, but when I rang to ask they said they offer it. So always worth ringing up and finding out if a council near you are offering it yet.
Plus the new NDRS/JCAP is cheaper too
