Joint managers Craig Roche and Stephen Kirkham praised their Newark Flowserve side after they wrapped up the Notts Senior League Premier Division title.
If promotion is confirmed, Flowserve will become the first Newark side in the modern era to play step-six football.
On Saturday, they beat bottom-of-the-table Ruddington Village 15-0 to seal the crown with seven matches to spare.
The heavy victory was their 26th from 27 league matches.
Lee Potts scored a double hat-trick while Elliott King got on the scoresheet five times.
With the title in the bag, they will still have to wait until next weekend, when ground graders will assess if their facilities are suitable for step-six football.
Work has been ongoing to get the ground up to standard. Planning permission for floodlights and a stand was given by Newark and Sherwood District Council last week.
After the final whistle both Roche and Kirkham praised their team for the manner in which they sealed the title.
Kirkham said: “It is an unbelievable achievement.
“It is not just today but all through the season. To win 26 of our first 27 games is magnificent.
“We could not have seen that coming at the start of the season but they have played great football week after week.
“We have been trying to run our club like a step-six side behind the scenes and on the pitch, and the players have proved they are ready to take a step up.
“It is not going to be easy next season. It is going to be a new challenge and we are going to make sure we are prepared.”
'A great achievement'
Roche said: “I have never been involved in a success like this in Saturday football before and I couldn’t be happier with their attitude.
“To be the first team in Newark in a long time to reach step-six is a great feeling.
“Completing the job by the end of March with seven matches still to play shows how strong we have been.
“To get where we are with our facilities and in a position where they are now is a great achievement.”
They pointed to the 4-2 win over Southwell in September, when they came back from 3-0 down to win, as one of their highlights of the season so far.
Kirkham said: “If we had lost that one then it might have put a different complexion on things and we might not have the run we did in the end.
“It gave us the momentum we needed to keep winning week after week.”
Newark Flowserve continue their league campaign on Saturday at home against FC Cavaliers, the only team to have beaten Flowserve in the league this season.
