Havant recorded a thrilling 36-16 win at Sidcup to all but alleviate any London one south relegation fears.
The victory stretched the gap between the Hooks Lane side and the relegation zone to 12 points, with just three games remaining.
Havant coach Will Knight believes, barring a complete disaster, his side should be safe.
‘Other teams now have a lot to do to overhaul us,’ said Knight.
‘The manner of our performance, particularly in the second half, can give us a lot of confidence going into our final games.
‘During that period we showed a lot of commitment passion and precision.’
Havant trailed 13-11 at half-time after a traditionally slow start.
Both Mick Goodger and Bruce Neil were sent to the sin-bin as the visitors found themselves in trouble.
Sidcup opened the scoring with a try midway through the first period and soon added a penalty.
Havant hit back with veteran centre Grant Morris going over for a try in the corner.
Although the home side added another try, Joel Knight pegged them back with two penalties before the break.
After a few stern words from the coaches, Havant exploded into action at the start of the second period.
Dave Sweeney dropped a goal to put the visitors in front for the first time.
But they soon fell behind again to another penalty.
With the game in the balance, it was Havant who showed they had the greater appetite for the contest.
‘Our players put their hands up and showed they were prepared for the battle,’ said Knight.
‘We grew into the game and by the end we were dominant.’
With Havant in the ascendancy, Joel Knight scored two tries, plus a penalty and a conversion to stretch Havant’s lead to 31-16.
With the game won, winger Loz Blackburn put the icing on the cake with a try in the corner to secure an all-important bonus point.
‘In the second half our forwards fronted up and provided us with the control and platform we needed,’ said Knight.
‘It was pleasing to see us playing with such intensity.’
