Will Knight is looking for another top performance as Havant visit Guildford in London one south.
Havant beat previously unbeaten league leaders Chobham in their last outing.
But head coach Knight knows his team can’t afford to relax.
‘I am looking for us to build on what we achieved against Chobham,’ said Knight.
‘It wasn’t just the result that was great but also the level of performance.
‘We played with a good intensity and closed Chobham out.
‘I am looking for us to do the same against Guildford, producing the same fire and organisation.
‘If we can do that we are capable of getting a similar result.’
Knight is forced to make a few changes to his starting line-up due to injury and unavailability.
Prop forward Jack Ward-Golden has tweaked his back and will be replaced by Jake Biggs who will be making his first start of the season.
Back-row forward Steve Cruddas is unavailable so Luke Barefoot comes in with Joe Davis moving across to number seven.
There is just one change in the three-quarters where Harry Carr returns on the wing, in place of Richard Gumbleton.
‘Harry Carr scored a try hat-trick on his debut and is a very strong runner,’ said Knight.
‘It is up to us to create opportunities for him and make the most of his talents.’
United Services are aiming to get back to winning ways in their Hampshire derby at Eastleigh in London Three South West.
Director of rugby Matt Davis believes Services can get something from the game.
He said: ‘The aim is to establish ourselves at this level and Eastleigh will be a good marker.’
Services have experienced outside-half Jim Taylor back but are missing injured scrum-half Ben Smith. Luke Peters returns on the wing.
