Havant suffered an agonising 26-25 London one south defeat at Chobham.
Gareth Davis had a chance to win it for the visitors at the death but his penalty shot fell short.
Head coach Will Knight felt it was a frustrating afternoon for the visitors.
He said: ‘To be fair we probably played the better rugby again.
‘Unfortunately we left far too many scoring opportunities out there
‘Those eventually came back to bite us.
‘We have to learn to control the ball better when we get close to the opposition line and not panic.’
A missed tackle allowed Chobham to lead after only three minutes but the visitors hit back quickly.
Armundus Morgan went over for a try, converted by Gareth Davis, after a series of driving mauls.
The two sides swapped penalties before Jerome Trail finished off a superb Joel Knight break from inside his own twenty-two.
Chobham reduced the arrears with penalties either side of half-time with Davis replying in kind.
Knight added another Havant try but the hosts got their winning score ten minutes from the end.
