The Swan Yamaha rider leads this season's standings by 28 points from Australia’s Josh Brookes ahead of the trip to the Kent circuit.
Last time out he secured a hat-trick of victories at Oulton Park, but he is not taking anything for granted.
"I treat every round the same, but the last time I raced on the Grand Prix circuit was when we won the title so I have some really good memories," the Lingfield racer said.
"I think we have seen from the rounds before how strong the competition is so you cannot rule anybody out.
"Three wins at the last round was good but we still need to stay ahead of the game and we saw last year that one point can make the difference between winning the championship so I will be pushing 110 per cent for wins for myself and Swan Yamaha."
Brookes has not won a race since Thruxton in April despite a consistent run of podium finishes.
Seven riders have already won races this season and a further four riders have scored podium finishes.
Hill's team-mate Noriyuki Haga is hotly tipped this weekend as he returns to the track where he has won five World Superbike races.
The Japanese is sixth in the standings, just inside the cut-off for the end-of-season Showdown.
"Brands Hatch is one of my favourite tracks and we have now found something with the setting that felt much better at Oulton Park," said Haga.
"The team have been working with that to prepare something for the race this weekend and I have good experience of this track. I know Tommy will be fast, so we need to work hard again because we want podiums and it was unfortunate that we didn't get one at Oulton Park.
"We did get some good points and now we are in the top six; this is important but of course now we need to stay, so we will try and fight for podiums at Brands Hatch."
There is a shorter layout of the track named the Indy Circuit, which the series visited in the season opener in April.
