On Monday, Williams announced their new partnership with ROKiT and it's the telecommunications company that will help Hamilton make an appearance at every BTCC race this season.
Hamilton, 26, has cerebral palsy, spoke of his delight on his racing return.
"I can't actually believe that I will be back on the grid this year. I have been in and out of different series since I started racing due to a lack of funding and general support," Nic Hamilton told Autosport.com.
"A lot of people assume that due to my name, I will have all the funding in the world. This could not be any further from the truth. I have been on my own for the past six years, grinding away, trying to get a full season under my belt with all the support I need"
