The Motor Sports Association are making steps to make HANS devices (aka Frontal Head Restraints) mandatory for circuit racing, with a two tier process starting in 2015 and continuing into the 2016 season.
For the 2015 season, drivers of single seaters built from year 2000 onwards will need to have a HANS device or similar.
Drivers may also need to consider replacing their helmets with ones with HANS attachment posts. Some helmet manufacturers offer a service to retro-fit HANS posts to some helmet designs that require drilling. If you have pre-drilled holes, you may be able to buy the posts to fit yourself. Do not drill your own helmet.
