Chelmsford record back-to-back victories in London 1

In doing so, the north Essex side climbed to ninth position and moved nine points away from Chingford, who are currently sitting in the third relegation spot.

In scoring four tries, Chelmsford also recorded an important bonus point, wing Jamie Ash scoring a hat-trick.

However, the win was tempered by the loss of influential loose head prop Stephen Prest. He suffered a torn hamstring which is likely to keep him on the sidelines for up to five weeks.

After some early free-flowing rugby from both teams, Chelmsford were awarded a penalty on 10 minutes, after an infringment in the scrum.

Fly-half Simon Hoult was on hand to kick a well-taken penalty from 37 metres out to put the visitors into a 3-0 lead.

Chelmsford then contrived to give away a series of penalties in a three-minute spell and from the last one, Harrow had the chance to draw level, but the kick was missed.

Once again, Chelmsford began to exert pressure on their opponents in the set scrums, but they found themselves on the wrong side of the referee on a number of occasions and their indiscipline led to them giving away nine penalties in the first half.

Just after 20 minutes the referee yellow carded Rest for being off his feet and minutes later a similar penalty offence saw the home side draw level.

A shoulder injury to Nick Sany led him to temporarily leaving the field, but not before a penalty to Chelmsford was reversed for the second row retaliating for the blow received to his shoulder.

Matt Lincoln replaced him and the last 10 minutes of the half proved to be fruitful for Chelmsford as Harrow were caught offside and Hoult drilled the ball to within five metres of the line.

Another offside infringement saw the Harrow no.8 yellow carded, so Chelmsford took the scrum option, which had to be reset. The resultant pressure on the Harrow scrum saw it disintegrate and the referee awarded a penalty try which Hoult converted to take Chelmsford into a 10-3 lead.

Minutes before the break, Dan Idundun fed Ash, who showed a clean pair of heels to notch his first score, a well-taken try, Hoult converting.

In the second half, Ash went over again, but this time the referee ruled out the try for crossing.

Chelmsford scored their third try when Idundun ran strongly to beat the cover defence and score a try by the posts which Hoult converted.

Thirty minutes elapsed before Chelmsford scored their fourth and bonus-point try when Seth Robinson picked up a loose ball and fed wing Ash, who ran down the touchline to score by the posts, with Hoult converting.

Harrow were then awarded their second yellow card for collapsing the scrum, before Chelmsford scored their final try. Ash showed a great turn of pace to beat the cover defence and complete his hat-trick of tries. Zane Mannan converted the extras.
