The Hammers signed Hugill from Preston North End near the end of the January transfer window, and the forward has already made two substitute outings in the Premier League.
The second came in Saturday's 2-0 win at home to Watford, and the Englishman has acknowledged that he is keen to make an immediate impression at his new club.
The 25-year-old told West Ham's official website: "Everyone's been really good to me, the players, staff, everybody. The lads have made it much easier for me to settle in because they're a good group.
"I'm doing bits after training just to get myself prepared and ready for when I'm needed. When I get the call I'll be ready for it.
"To get on for my home debut was a big moment for me, and getting the three points makes it even sweeter so it was a great day overall."
West Ham are next in action when they face Liverpool at Anfield on February 24.
