The Tangerines hauled themselves back into the game in the 48th minute when Tom Ince cancelled out Carlton Cole’s opener.
But Vaz Te was on hand to fire home in the 88th minute to seal the Hammers’ return to the Premier League at the first time of asking.
“Well done to West Ham,” Holloway told Sky Sports.
“It looked like it was going to extra-time. I was very pleased with our performance overall.
“When they scored we lost our shape and belief and I asked them to do certain things at half-time. Like my lot, they went out there second half and put in a fantastic performance.
“I’m very proud of my players and my fans. Unfortunately we didn’t deliver.
“All you can do is congratulate the opponents. I thought we gave a great account of ourselves today.”
