Edgehill pulled a goal back from a Luke Jones penalty late on after an Adie Blake handball but Pier than enough to completed their flawless record to wrap up the title.
Pier boss Andy Spivey said: "In between our goals Edgehill had three efforts cleared off the line and overall they were very good and a little unlucky to lose. Credit to them as they have massively improved from last year.
"Credit to Pier for seeing home a perfect league season, once again it was a great all-round team performance.
"Keeper Scott Wardman, and the back four of James Wardle, Niall Gibb, Adie Blake and Gary Thomas kept Edgehill out, while the midfield of Martin Cooper, Tommy Barker, Sam Garnett and Will Jenkinson worked tirelessly, and strikers Jimmy Beadle and Jamie Bradshaw tormented the home defence throughout."
Spivey added: "I am delighted to have won it, and it is fantastic to win it unbeaten and 100% record which was last done in 1997."
"I would like to thank and also congratulate each and every player who pulled on a shirt for West Pier this season. All have contributed to a real team effort. Their desire to retain their title has been truly outstanding"
"It's been a long, long season and their success in securing the league and League Cup double is a well-deserved reward for their efforts"
