Callum Grieve converted early scores from Obonna and Sam Pim for 14-0, the visitors hitting back as Lloyd Hayes added to an Aidan Shortall score before Jamie Cooke crossed the whitewash.

Sam Dardis pushed Mond’ further ahead before Cooke’s second was added to by Hayes for a level game, Luc Jones over and Grieve on target for a 26-19 lead at the break.

Yet Hayes kicked a penalty adding the extras to a John Okafor try, only for Obonna to have the final word right at the death.

However, the boot of Burgess was on song following tries from Jake Lloyd and a 78th-minute Noah Sloot effort to snatch victory for the Londoners.

Albion moved further clear with a converted Morgan Stone effort, Esher’s Henry Mortimer and Plymouth’s Craig Duncan then exchanging tries, another Putt kick making it 34-17.

Tarling’s converted second and an Elsworth penalty nudged Dings 10 points clear before Powell slotted following an Alex Gilham try for 29-26.
