Havering's men produced a dominant display to run out 3-1 winners against Witham at Campion.
Expecting a difficult fixture against a side who had scored seven against Southend a week earlier, the hosts began brightly and took the lead when Adam Willett found Harry Andrews to fire home from the top of the D.
Havering capitalised on their speed in attack again when Sam Green reached the ball and found debutant Andy Brennan to slide past the keeper.
And they continued to create chances in the second half, moving 3-0 up when Green's looped effort found Liam Purton at the far post to net at close range.
The visitors grabbed a consolation two minutes from time with a cool finish past Andy Gaut but Havering were good value for the points.
A weak second team slumped to a 13-0 defeat in the reverse fixture at Witham, who had an ex-National League player leading their line.
And the thirds also lost to their Witham rivals, falling behind to a short corner just before half time.
Fantastic play on the left by Eli Cook set up a short corner chance for Luke Clarke to level, but Witham went on to win 3-1.
Drew Cook was man of the match for Havering, as Bill Birbeck took defender of the match honours.
The fourths had to concede their match against Old Loughts sevens due to unavailability.
Havering women were on the wrong end of a 7-0 defeat at St Albans seconds.
Sue Harwood saw an early effort cleared off the line by a retreating defender, after a lovely pass from Katie Griggs, and Catherine Johnson was unable to convert Emma Sharp's hard ball into the D from the sideline ball.
Steph Prowse could not get on the end of a return pass from Harwood before the hosts opened the scoring.
Sophie McCoy made several good saves, as Sharp, Prowse, Bukki Olodo, Monica Dubb and Nic Earle came under heavy pressure.
But Saints doubled their lead after turning over possession and a short corner strike made it 3-0, while quick movement from a free hit led to a fourth before half-time.
More pressure led to two more goals after the restart and, although Johnson, Prowse, Alex Semon, Alison and Bethan Isherwood, Griggs and Tilly Bunn strung some passes together, Havering struggled to create clear chances.
Saints completed their tally from a penalty corner late on.
The seconds saw Chelmsford fours take the lead against the run of play and add a second before the break.
