Jake Speight scored twice in the first half as Alfreton claimed a comfortable victory over Halifax.
The on-loan Mansfield striker opened his account when he lashed home from 12 yards out.
He headed his second in from close range after John Akinde nodded back a Josh Law corner.
Akinde then got on the scoresheet after the break, capitalising from close range after Halifax failed to clear their lines.
Lee Gregory hit a post late on for the visitors, whose three-game unbeaten league run came to an end.

Alfreton Town manager Nicky Law told to BBC Radio Derby:
"I thought it was a great all round performance against a side which has obviously scored a lot of goals this year.
"You can see why. They've got centre halves playing in centre midfield and they're a big strong powerful side, but we matched them.
"Without being too disrespectful, I think it could have been six or seven nil. I'm not saying it should have been, but it could have been.
"We had that many chances and I think we limited them to very few and I think it was a great all round performance to be fair."
