BT Openreach have yet to launch the self-install FTTC wholesale product, so no ISP can offer a self-install product at present.
Clearly, self-install is close - the technical specifications for filters and CPE (consumer premises equipment: modem or router) have been published, and various compatibility tests and field trials have taken place. EE has already switched to a router with built in VDSL2 and ADSL2+ dual mode modem on some of its packages, which will be eminently suitable for self-install. BT Retail have announced the Home Hub 5 that is supposed to contain an integrated dual mode modem, but I'm not sure whether it is available yet to their customers. Other ISPs, including PlusNet, have surely got something similar in the pipeline.
Is there a particular reason why you want to wait for self-install? The current engineer install packages attract modest up-front fees, and you can always request the engineer doesn't fix the modem to the wall. Once self-install is launched, it is unlikely there will be any barrier to unplugging your BT Openreach modem and connecting a router with a VDSL2 modem, much as those with engineer install ADSL unplugged their 'frog' and replaced it with a router.
If you are certain the engineer install option is not for you, hopefully there will not be much longer to wait.
