No. But...It depends on your set-top box.
TiVo itself has no concept of SD/HD, it simply takes the signal coming in the scart lead and records it. It records the programme in the quality you choose (Basic/Medium/High/Best). But it's true that even Best quality is not HD-equivalent (and never has been).
As to BBC and C4 going "HD only" well your ability to keep using TiVo depends on your receiving equipment. If you use satellite (Sky, Freesat, or "Freesat from Sky") but it only does SD then your set-top box will no longer be able to decode the programme stream after the switchover, so you will lose all your TV programmes. However, if your sat box is HD then you will be unaffected (other than some channels changing numbers).
If you use a Freeview box then I don't know of any planned changes here, so you will be unaffected.
So:
Freeview -- no change
Satellite HD -- no change
Satellite SD -- you will need to buy an HD box.
